2021 Subaru Forester

The contact owns a 2021 Subaru Forester. The contact stated that while trying to roll up vehicle windows from driver sits and passenger sit they would roll up to 3/4th all the way up and they would roll back down after. The contact stated this was a recurring event. The dealer was aware of failure and diagnosed issue needing repairs for window regulator and run channels for driver and passengers side. Manufacturer was made aware of failure and let contact know it was outside of warranty. The failure mileage was approximately 22,500.

My 2021 Subaru Forester has a recurring, worsening defect in the Idle Stop/Start (ISS) system that creates a stalling hazard. When ISS shuts the engine off at a stop, the engine intermittently fails to restart when I try to move again. It cranks progressively slower, warning lights illuminate, a continuous alert sounds, and the vehicle cannot proceed until I shift to Park and restart manually. This has left me immobile in live traffic at lights, stop signs, and mid-turn. The system also attempts to shut down in unfavorable moments, such as mid-turn, or as I am already releasing the brake (meaning it was depressed only lightly or briefly); it then tries to restart while still mid-shutdown, producing a pronounced shake. This is not a battery-charge problem. It has occurred even when the battery tested above its rated cold-cranking amps, and after each failure the engine restarts smoothly by manual start, indicating the starter, engine, and fuel systems function normally. I raised this before 2024, but it was not recorded until May 2024. At that visit the dealer performed the TCM reprogramming in Service Bulletin 16-147-24 (Forester, auto start/stop engine speed drop on restart) plus an ECM update. A later visit added another ECM update. A dealer has now identified yet another TCM reprogramming, quoted for a fee. The failure has persisted across all of these updates. Dealer staff acknowledge repeated customer complaints with these exact symptoms and say there is no known effective fix. Because ISS cannot be permanently disabled through any factory control, I must remember to disable it manually every drive to avoid a restart failure in traffic. The vehicle is available for inspection. This is an ongoing, unresolved safety defect that repeated manufacturer software remedies have failed to correct, and it can leave the vehicle disabled in live traffic.

Persistent Battery Drain on a 2021 Subaru Forester Limited. Problems began in year 4 of ownership (~17,000 mileage), after Subaru Starlink Subscription services expired. Red (Error) Starlink SOS indicator light was evident, where a normal light would show green. Battery would fully drain after about 3-4 days of inactivity while parked in a commercial garage. After repeated dead batteries, a jump-starter battery pack was used regularly, as well as a wall-outlet battery charger. The problem has not resolved with a new and appropriately specified AGM battery, replaced in December 2025. The only solution is to pull the engine-bay fuse #5, which disables the Data Communication Module (DCM), as well as other features (hands-free microphones and audio system). By pulling the fuse #5 consistently, the problem has ceased, even after a two-week period of no use. This provides irrefutable evidence that the DCM powered by fuse #5 is the source of the battery drain. The only resolution Subaru would offer was to insist on a dedicated diagnostic visit to a dealership, with the associated costs of hundreds of dollars to be borne by me, the customer, without a clear understanding of the costs or remedies to resolve this problem. I feel unsafe driving my vehicle for more than short trips given the risk of stranding or further electrical malfunctions that would impact critical vehicle functions or safety systems.

Driving along and various system warnings came on, then started losing power, then the engine died and the car was completely dead. Got a jump start and the car ran for a couple of minutes and died again. Had it towed to a repair shop and when they checked it the next morning, they couldn't find a problem and it ran great for them. I replaced the battery and alternator just to be safe because we were about to leave on a trip.

2021 Subaru Forester The vehicle has experienced recurring electrical and battery-related issues for several years. The original battery was replaced by the Subaru dealer with a larger-capacity battery because of repeated starting concerns. The replacement provided only temporary improvement. The vehicle continues to experience rough starting on a regular basis, even after installation of a newer aftermarket battery with a higher cold-cranking-amp rating. The current battery is approximately five months old. The most significant safety concern occurs during Auto Start-Stop operation. On multiple occasions, the engine has shut off at a stop as intended, but then failed to restart when attempting to move again. When this occurs, multiple warning lights illuminate on the dashboard and the vehicle is unable to proceed until it is shifted into Park and restarted manually. Because of this issue, I now disable the Auto Start-Stop feature on every drive to avoid a potential failure to restart while in traffic. The issue has been ongoing for years and has occurred with multiple batteries, including the dealer-installed replacement battery and a newer aftermarket battery. The dealer suggested that an aftermarket dash camera could be contributing to battery drain. The dash camera was disconnected, but the problem continued. I am concerned that failure of the vehicle to restart after Auto Start-Stop operation could leave the vehicle disabled in traffic and create a safety hazard. The condition appears to involve the vehicle’s electrical system, battery management system, charging system, Auto Start-Stop system, or a combination of those components. The vehicle is available for inspection upon request.

My Subaru Forester has a significant safety defect. If my web searches are representative this software problem affects multiple models and years of Subaru. I have addressed this problem with the local dealer, Subaru America, and Subaru Japan and have been told "that is the way it was designed and it is supposed to do that." As you may imagine that is not a satisfactory answer to a significant safety issue; I can only imagine Ford saying the Pinto was designed with a gas tank that explodes in a collision or a more recent Takata claiming that their seatbelts were designed that way. So here is the problem in a nutshell (and I have a host of Emails from various levels of Subaru if you want the details of how I have attempted to get them to address the issue.) There is a sensor on the gas cap that detects if it is not fully closed since that is a pollution control issue. (More on that later) When that sensor is activated, it disables the Subaru Eyesight system and when the Eyesight system is disabled it disables every safety feature except the seatbelt and it lights up the dash with a dozen alarms none of which have anything to do with the gas cap. That takes down collision avoidance, lane changing, and autodim headlights among others. It also wants you to check the engine and consult the users manual. None of that has anything to do with the actual situation. Now I have taken the car to the dealer who assures me it is operating as designed and there is no fault in the sensor. When you close the gas cap there are audible clicks and as a 190 pound man I can assure you that the cap is fully closed when I close it. But on a random basis the dashboard lights up despite the fact that the gas cap is fully engaged and the safety systems become disabled. Usually it stays lit up until I refill the tank, but its behavior is not predictable - occasionally it just resets as I drive. Besides the obvious hazard of having safety systems which do not work, havi

I am filing this complaint regarding a recurring and dangerous safety issue with my 2021 Subaru Forester. The auto stop/start feature intermittently fails to restart the engine after it shuts off when stopped. When this occurs, multiple dashboard warning lights come on, an alarm sounds, and the vehicle requires putting the transmission into "Park" and shutting it down completely before it will start again. This has happened multiple times at intersections, traffic lights, and freeways during rush hour (stopping and starting frequently), leaving me temporarily stranded in live traffic. The local Subaru dealership service department was unable to replicate the issue, however upon inspecting the vehicle's charging system, the battery was found unable to hold charge from the alternator and was replaced on June 9th, 2025. Now after less than 1 year of replacing the battery, the problem persists. I have been made aware of TSB 16-118-24R (TCM reprogramming for auto start/stop restart failure) and TSB 09-80-21 (Thermostatic Control Valve failure) which appear directly related to this issue. This is a serious safety hazard. A vehicle that cannot restart in live traffic puts the driver and other motorists at significant risk of a crash. I am requesting that NHTSA investigate this issue and consider a formal recall.

While driving this car on April 4, 2026 at around 6PM, I experienced the distinct smell of gasoline. I had driven for about 5 minutes on our way to a local restaurant that is approximately an 8 minute drive from our residence. My wife said that she had just filled the gas tank that afternoon. After arriving at the restaurant, I checked the gas cap to ensure it was tightly sealed. I also checked to ensure no fuel was leaking from the car. After finishing dinner, we I drove the car back to my residence and once again, 5 minutes into the drive, I smelled gasoline. After we arrived home, I check the vehicle exterior for leaks and found no liquids under the car. The following day, April 5, 2026 at approximately 1115 AM, having once again found no liquids or gasoline under my car, I drove the car to my local repair shop; an 8 minute drive. About 5 minutes into the drive, I smelled gasoline again. I parked the car at the repair shop, but while adjusting the parking to fit better between the painted lines, I saw and heard a large puff of smoke from the hood area. I immediately put the car into Park, shut off the engine and ran from the car. After exiting, I saw that the car ignited with visible fire under the engine compartment. I called 911 to request fire department help. No damage to any structures or other cars occurred. Q1 Above: No the car is totaled and unavailable for inspection as far as I know. Q2 Above: I had to run from a burning car. Q3 Above: No. Q4 Above: Yes, the car was inspected by my insurance company, USAA. Q5 Above: No, there were no warning lights or any indictor that there was trouble. I would like to note that the car was brought in to my Subaru dealership service station (Hyman Brothers in Midlothian, VA) for a heater element safety recall several months ago.

While driving the car, the engine stops completely. After a few seconds, it can be restarted. It does this several times a week at random intervals. It's very dangerous since it usually happens when we're driving in traffic. The dealer checked it out in July but couldn't find anything wrong. Even though it's a serious safety problem, they said to keep driving it until it does it every time the car is driven or until the car won't run. When this happens, all the dashboard warning lights come on and the word "Eyesight" is displayed with a diagonal line through it. A warning buzzer also sounds. This started last summer with very infrequent occurrences and is now several times a week.

On January16,2026 while driving from Houston,TX to Austin TX the vehicle experienced a complete loss of power on Highway 71 W. We were traveling at approximately 70 MPH when the engine completely failed. We were forced to immediately pull over onto a narrow shoulder Our situation at that point was dire: we could not exit the vehicle as other cars were speeding by. Fortunately an emergency vehicle from the Texas Department of Transportation pulled up behind us with his emergency lights flashing. He told us we were in a dangerous situation and, due to our location, he was not able to tow us to safety. Our only option at that point was to allow the emergency vehicle to puss us to a safe location off of the highway. The driver pushed our vehicle approximately 1/2 mile to a motel parking lot. We contacted Austin Subaru, arranged for a tow truck, and proceeded to the dealer. The dealer technician advised us the Thermo Control Valve had failed. We were told this failure was common. The repair was at no charge since Subaru, being aware of the problem, had extended the warranty on this part. The action by Subaru to extend the warranty instead of proactively replacing the part before failure seems blatantly irresponsible

I am writing to file a formal complaint regarding repeated, severe, and dangerous malfunctions of the vehicle's engine Start/Stop (Idle Stop) feature. The system is failing to operate as intended, resulting in the engine stalling while the vehicle is in motion or under crucial driving circumstances, creating significant safety hazards. History of Incidents I have experienced four separate incidents where the engine unexpectedly stalled or shut down, creating extreme risk: Incident 1 (Railroad Tracks): The engine stopped while I was actively driving over railroad tracks. The car stalled on the tracks, and within seconds of the engine restarting, the crossing gates came down and a train passed. I narrowly avoided being hit by the train, missing the impact by approximately ten seconds. Incident 2 (Heavy Traffic/Bridge): During heavy, back-to-back traffic as a bridge (PGA bridge) was opening, the car momentarily stopped and then resumed movement. The unpredictable stopping motion created a severe risk of being rear-ended, as the following vehicle would have had difficulty anticipating the sudden, unintended stop. Incident 3 (December 2025): While taking a right turn, the engine stopped suddenly, with dash lights blinking, during only a slight pause in vehicle movement. This occurred while the vehicle was still maneuvering. Incident 4 (The following day): The engine stopping malfunction described in Incident 3 occurred again the next day. Attempted Repair and Ongoing Concern Two years ago, the dealership installed a new battery following the first two incidents. However, the problem has now recurred this week (December 2025). The dealership has informed me that using a third-party device to permanently disable the Start/Stop function would void the powertrain warranty. Causing Mechanical Stress: I believe the continuous, potentially faulty activation is putting unnecessary stress on the battery, electrical system, and engine components, which may ultimately shor

My Subaru has an auto start/stop. I was at a complete stop, making a left-hand turn, and my car completely shuts off with the following message: For safety, auto restart disabled; eyesight with a \ through the words, put car in park and restart vehicle. In the time it took me to put the car in park and restart, I was almost T-bone. This was terrifying. This had happened on previous occasion in stop and go traffic which is dangerous because my car has come to a complete stop without any warning to me where the driver behind me There are no warning symbols, warning lights, or any type of signal or symptoms to notify me that my car was going to stop completely.. Typically I remove my foot from the break, the car starts and then I put my foot on the gas pedal and the car moves forward. In the situations described above the car just stopped.It just flat out stopped. There’s never been any indication or signal to indicate the car is not going to restart The retailer replaced my battery and said it should help. I called the Subaru factory rep who was of no help. She said she is not a trained technician and all that she could offer to do was to contact the retailer. The dealer was not able to reproduce the problem. The retailer replaced the battery without any response about the safety issue. I asked if Subaru had a safety board I could report this too and the factory rep said no, but she will document it and they’ll do an internal review to see if we have any other similar issues reported, however, they will not contact me because they don’t talk to the public about these issues. I told her there are hundreds of these if not, thousands concerns online stating the same issue. The rep said she would document my concern. Documentation is good if there’s a fix but I’m concerned about the unnecessary death of a driver.The retailer also advised I could do the auto start override, I’m trying to make a point of how serious of a safety issue this problem can be.

The vehicle has experienced four separate engine shutdowns while stopped in traffic. Each time, the engine turned off unexpectedly, requiring a manual restart. One incident occurred near a railroad crossing with my child in the car. The vehicle also lurches forward at low speeds and hesitates when accelerating after being stopped. These issues persist despite service visits. I believe they may relate to Technical Service Bulletins regarding the Auto Start/Stop and battery systems (TSBs #16-147-24, #10232217, #07-218-23R, #10251098). Subaru service staff have acknowledged awareness of these problems. I’m submitting this complaint to ensure the safety risk is documented and investigated.

Issue started with hearing a clunking noise from the front of the car, had the dealer inspect at 37,000 miles. They said they the clunking was caused by ECU issue and reprogrammed the ECU to correct it. Obviously, a software update did not correct the noise. Had an independent repair shop inspect the vehicle and found both front control arm bushings were cracked and torn allowing the control arm to move around causing the noise. Since the control arms are an integral component of steering the failure of these bushings could've caused loss of control, or an accident. They were replaced by the independent shop and now the noise is gone.

Unintentional Acceleration - 2 times within 4 days of each incident. 9/17/25 while stopped to pull into a parking lot my 2021 Subaru Forester accelerated as I was stopped. I had to slam on the brakes, take a deep breath and was shocked at the pull and speed the car wanted to go. 9/20/25 Pulled into a parking spot, not moving and the car again pulled and accelerated. Again I slammed on the brakes to stop from crashing into other vehicles or whatever was in the vicinity the car wanted to go. There were no warning messages, no symptoms prior to these 2 incidents. The car only has about 24,000 miles on it and all maintenance has been done on time and at the dealership. No outside mechanics have ever worked on the car. I called AAA to tow me as I was not safe to drive the car and had it towed to the Suburu Dealer where I purchased the car. This is an extremely dangerous situation. The floor mats were not near the gas pedal or the brake pedal and It was absolutely 100% not my error in foot pedal placement. I will not drive the car any longer until the dealer calls to tell me what is wrong or what they have found to be the problem. There is a civil lawsuit against Subaru for this situation but when mentioning it to the dealer they acted like they knew nothing about it. This is not something that should be ignored. I was lucky the 2 times it happened and I hope to God it never happens again!

I was going down a highway using the lane keeping assistance feature. Suddenly the vehicle stopped following the road and ran me into a ditch. I was able to steer back onto the road, but if the ditch had been deeper I believe there would have been a rollover accident. The root cause is that when the audio system is turned up in the vehicle, the warning chimes do not interrupt the music or sound loudly enough to be heard over it. When the vehicle needs manual intervention assistance staying on the road, the driver may not hear the warning sound in time before the system disengages. The warning chime sounds need to be able to be heard over the audio system. This exact thing has happened to me 2-3 times in the last year.

After arriving home from a short drive to the grocery store I parked my car in the drive way and went inside. On the drive home I could hear a low humming coming from the speakers and the car was decelerating when the accelerator was not being pressed, no warning lights or sounds came on. About 10 minutes after I parked a neighbor knocked on the door letting me know my car was smoking from inside the hood. Within a minute or 2 the entire hood of the car was engulfed in flames. The entire front half of the car burned to a crisp, the fire also burned half a tree. The car was burning so hot that it melted the hood of the car, had I parked it with the hood facing my house my house would have caught fire. The problem has not been reduced or confirmed by dealer or independent service. The vehicle is being stored by the insurance and for the time being is accessible for investigation. Because I was having trouble with the infotainment system, the humming coming from the speakers, and a recent warranty extension by from Subaru for the infotainment system due to known issues I suspect that the fire was caused by electrical issues.

On 8/12/15, I had stopped at a stoplight. When the light changed and I attempted to move forward with traffic, the Eyesight Disabled warning came on and my car completely stalled and refused to move. The car prompted me to put it into park, I attempted this and it did not resolve the issue. After this, the car prompted to press the start/stop button. This also did not work. I eventually had to completely turn off the car while in an active lane of traffic and turn it back on. This resolved the issue. In less than 24 hours, I was at the dealership. They have been unable to determine what caused the vehicle to effectively shut off while idling. They are performing a TCM update and do not appear to believe the issue is a safety issue, however again the vehicle stalled in an active lane of traffic during rush hour. It felt like when the car goes into the gas saving mode while idling but this had not happened. It just stopped. This was an extremely unsafe situation to be in a car that can not move or have to try and get it into neutral and get it out of traffic on a busy road, moments after being on the highway. The dealership checked the battery twice and confirmed that it was functioning and I have the video walk through where the confirm the car is in good condition and they could not replicate the issue.

On August 12, 2025, at approximately 10:16 AM, while driving at normal speed on CR-43 NW southbound just past Minnesota Ave in Big Lake, MN, my Subaru’s EyeSight Driver Assist System, specifically the Automatic Emergency Braking (AEB) / Pre-Collision Braking System, suddenly activated without warning and with no obstacle present. The braking was abrupt and unnecessary, causing the vehicle behind me to nearly rear-end mine. Road conditions were clear, dry, and unobstructed, with no pedestrians, vehicles, or hazards in my lane. This appears to have been a “false positive” from the AEB system. This sudden stop placed both my safety and the safety of other drivers at serious risk, and in different circumstances could have caused a collision resulting in injury or death. The vehicle is available for inspection upon request. The problem has not been reproduced or confirmed by a dealer or service center because Subaru requires a $200 diagnostic fee, which I have not paid. The vehicle has not been inspected by Subaru, police, insurance, or any other parties for the same reason. No warning lamps, error messages, or other indicators appeared prior to the incident. All systems appeared to be functioning normally before the unexpected braking occurred. I am concerned this defect persists beyond 48,000 miles, outside the limits of prior settlements, and believe Subaru should issue a recall covering all affected vehicles, regardless of mileage, to prevent potential crashes.

We purchased a 2021 Subaru Forester Touring SUV on [XXX] at the El Cajon Subaru dealer and this July, I experienced the transmission (CVT) inadvertently shift from drive to neutral twice in one day. This was a concern to me and after I did research online, I was very surprised to discover that this has been an apparent issue with the CVT transmission. We then arranged to have the vehicle towed to the Kearney Mesa Subaru in San Diego for them to diagnose the problem. They found NO issues! I contacted the Subaru Manufacturer at Subaru.com and received a Case # and Jorge, a customer service individual called us today, 8-6-2025 , to address my inquiry. He informed us that if the dealership was unable to duplicate the problem then he was unable to request further action. This was an issue that he was unfamiliar with, or had ever even heard of, and could only suggest that we have the vehicle seen, again, by another dealership to see if they can determine the problem. This is very disappointing as we have only driven this vehicle less than 1000 miles since purchasing. And since I'm now reluctant to drive any distance in this vehicle, or on freeways, will need to have it, again , towed to another dealership as suggested! I would very much appreciate any information you can provide on how to approach this circumstance and if you have encountered any additional complaints specifically related to the Subaru CVT transmission shifting unexpectedly into neutral. Thank you for your attention to this request as we find this a significant safety concern that needs to be addressed. .INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crash

While driving on I-17 Southbound near mile marker 311 at approximately 75 mph, I experienced a sudden and dangerous malfunction of the Lane Keep Assist (Auto-Steer) system in a 2021 Subaru Forester. The feature was active at the time and unexpectedly veered the vehicle sharply toward the concrete wall on the left shoulder of the highway. I attempted to regain control, but due to the abrupt nature of the malfunction, I overcorrected and collided with the wall on the rear driver side. There were no vehicles in the immediate vicinity, or this could have resulted in a multi-vehicle collision at high speed. I hit my head during the impact but did not require emergency medical services at the scene. Road conditions were dry and clear, with no visible debris or extreme weather factors. There were no warning lights or error messages from the vehicle prior to or during the incident. The Auto-Steer system did not disengage on its own before veering off course. This was the first time driving this particular vehicle, which was a company car, and I immediately reported the incident to my employer. The damage was reported and the vehicle is seemingly available for inspection. At the time of this report, the issue has not yet been formally diagnosed by a dealer or service technician. The failure of this driver-assist feature significantly endangered my safety and potentially the safety of others had there been nearby traffic. I am filing this report so the issue can be investigated, and similar malfunctions prevented in the future.

The Auto-Stop/Start feature frequently fails to properly restart the car, often causing the car to stall during the restarting process, leaving me effectively disabled on a busy road. The battery has already been replaced once.

I commute with my car and recently it started to speed up all by itself. I removed my floor covers thinking the gas pedal might be stuck on it but that wasnt the problem. While accelerating from a stopped position, it revs up and accelerates rapidly all by itself. Tapping the break pedal to deactivate accidendal cruise control doesnt work. I have to slam the break just to stop it from accelerating on its own. This is the fourth time it's happened. I have my personal mechanic change the oil every 3k miles and follows the factory recommendations on all other manufacturers recommendations. Very scary to drive because it happens at random.

My vehicle is equipped with automatic start/stop system. In early 2024, I began having issues with sluggish restart during the start/stop cycle. I took it into the dealer at that time, who stated it required a software update and charged the battery. The issue persisted. It was more serious, as it was not just sluggish on the restart, but the restart would fail and stall the car. This happened in heavy traffic, which was very scary and unsafe. I took the vehicle back into the dealer in late 2024 for the same issue. They did another software update and charged the battery again. They recommended that we purchase a new battery. One month later, we purchased an upgraded AGM battery, as it was recommended for auto start/stop systems. The issue continued to persist. First, with sluggish restart. Later, the auto start/stop system failed again in heavy traffic. We took the vehicle in again, and again the dealer stated it was the battery. They recommended we purchase a new battery. It was explained the battery was 6 months old, and the issue has never been fixed. Further, it was pointed out that the car could be restarted manually with the push button ignition, after a start/stop system failure. That led us to believe it was not a battery failure, but a deeper system failure. The dealer continues to assert it is the battery, even though it happened with a factory battery and a new, upgraded, battery. Neither of the batteries have failed testing, and report as "good" on the diagnosis forms. We believe there is a system issue, that is causing issues with the auto start/stop system, and is not being identified by the dealer. It is a safety issue, as it has happened in heavy traffic several times. We have attached diagnostic reports from March 2024 and June 2025, but cannot find the October 2024 diagnostic report.

The automatic shutoff that occurs when the vehicle stops to prevent idling, disengaged two separate times in the span of 4 days. Both incidents occurred at very busy intersections and failed to restart both times. When attempting to restart the car, lights came up on the dash, along with beeping, and failed to restart the car after the light had turned green. To restart, the car had to be completely turned off for about 60 seconds and then could be restarted. To avoid having to experience this issue again, or worse - get into an accident - I took it to the shop where they could not recreate the issue.

Without any prior issue of having the engine turnover from being parked for more than 20 hours, the car would not start. It’s like the battery completely died overnight. I was able to unlock it but the car would not start, and therefore was unable to go into neutral because I didn’t have a long enough screwdriver with me to manually override into neutral. So it had to be jumped partially to be towed (had it towed for more than just the battery because it’s under warranty). The interesting part is that my car has a factory issued battery, and my car was the third Subaru made after 2020 that had to be towed due to the same issue, in the same day. Maybe the batteries are defective? Regardless, since everything relies on power now, having a provided device to allow for manual override would prevent folks from being stranded. I tried using my key AND the screwdriver that comes with the spare tire. Both were to short.

Automatic stop activated at traffic light. When the brake was disengaged, the star would not start. The occupant was stalled at the traffic light during rush hour in a thunderstorm with limited visibility for approximately 15 minutes. Winter Haven Police Department was dispatched but did not arrive probably due to other weather-related traffic situations. After that time, the engine did start and was moved into a lot without incident. The good Samaritan that assisted stated he had just stopped down the street on another disabled vehicle in traffic due to malfunctioning auto stop/start. Here is the issue. The alternator and battery have both been checked twice and were in proper order. The OE battery was in use. There was no warning to indicate any issue with the batter. In fact, the Subaru app was reporting the vehicle was operating normally while the vehicle was dead in the road. I work with a local law enforcement agency and have worked fatal crashes on that road. It is unacceptable for the vehicle to not have some type of redundant system to warn owners that the vehicle battery is failing before they are thrust into a possible deadly roadway breakdown.

Was stopped at traffic light. Start Stop system was engaged. Engine turned off as normal. When I took my foot off the brake the engine did not engage and the Eyesight warning light came on that the Eyesight system was not functioning. Put the car in park and engaged the ignition button and the engine started. Turned off the Start Stop system and the car functioned normally after that. Have read postings on Subaru forum that this has happened to others.

My dealer diagnosed issues with my car as: the gasket around my sunroof failed and allowed water to infiltrate the cabin and the electrical system over time. This caused corrosion in the electrical harness, which caused battery failure, failure of the adaptive headlight system, and random electrical glitches. My interpretation of their diagnosis was that this was a cascading failure that might have led to problems with other electrical components such as power brakes, other adaptive systems, etc., and affected safety, if it had not been diagnosed in time. An insurance appraiser confirmed the dealer's diagnosis. Repairs (including replacing the electrical harness) have been completed and so the situation is not available for further inspection. When the adaptive headlight system stopped working, this was reported on the dashboard, but the cause of this and the base problem was not.

In the summer of 2024, my forester started completely stall out when I was stopped at a stop light. The auto start/stop system seemed to not turn back on. I would have to put the car in park, turn the car off and turn it back on. It was very scary being in traffic and people getting upset behind me. This happened multiple times. I took my car to the dealership. I was told an update needed to be installed and it was not anything I could do at home. After that point, it worked better, but still started back up hard at times. When I remembered, I typically started turning the feature off each time I drove it because I do not trust the feature. Unfortunately, it happened again yesterday. We were at a stoplight, and the car did not start back up, it stalled out. My husband had to quickly try to put the car in park, turn it off and then back on. Cars started honking at us. I am very concerned about this feature.

MY 2021 Subaru Forester battery has died twice in the last 10 months. I could not jump start the vehicle the first time about 10 months ago. I needed AAA to jump start it. I took the car to the dealer; they recharged the vehicle and said the battery was fine. They did not bill me. The car died again this week. This time I was able to jump start the vehicle myself. The safety issue is I might need to get to a doctor's appointment or other emergency in a hurry. I may be out shopping or hiking and need to return home, perhaps in bad weather. I might be stranded in a busy intersection or a lonely country road. The battery is simply not trust-worthy. The vehicle was inspected by the dealer, and they said the battery was fine. There was no warning lamp before the battery failed. The car is not safe-I don't know when it won't work.

12/14/24-I was stopped at a red light at a VERY busy intersection. The engine was in stop mode by the start/stop feature. When the light turned green, the car failed to start. The entire car shut down, with alarms sounding and dash lights flashing. The entire system had to reboot before I could restart the car. It was a freighting experience. Fortunately, I wasn't killed by traffic zooming by or by some person with road rage. 12/16/24-Issue evaluated by local Subaru dealer. Their evaluation was that when the auto start feature was activated, my car battery was too low to work. There was zero warning about a low battery before this failure in traffic. I had to buy a new battery. The auto start/stop feature is not an enhancement, but a safety hazard. Owners should be able to permanently disable this unnecessary drain on batteries and starters. I did a search, and there are plenty of others that experienced similar issues with their Subarus.
