2018 Chevrolet Volt

My 2018 Chevy Volt started making a creaking and clanking noise when driven at low speeds. Dealer diagnosed the problem as being the rear shocks and bushing. Replacing these did not fix the problem. Not sure if this is a safety issue or not.

The car suddenly lost power and produced error messages on the screen. I had to quickly change lanes to get out of traffic on the highway. My dealer diagnosed the issue as a BECM malfunction and quoted a repair cost of approximately $3500. However, due to my car originally being registered in California, this failure is not covered under GM Special Coverage Bulletin N232432680 (issued March 2024), which provides an extended warranty for BECM issues on affected 2016-2018 Volts up to 15 years or 150,000 miles. My VIN does not qualify for this coverage despite the vehicle being within the model years affected by known BECM soldering/connection failures. This appears to be part of a broader pattern of BECM defects in 2016-2019 Volts that can lead to sudden loss of propulsion, as previously investigated by NHTSA. GM should extend coverage or issue a recall for all affected vehicles, as this defect compromises vehicle safety and leaves owners with expensive out-of-pocket repairs for a known issue.

I was driving my 2018 Chevy Volt at about 30 mph on EV mode. The battery was at 50%, the car was performing normally. Then the battery jumped to 100%, the check engine light came on, and the vehicle lost power. I was in rush hour traffic and unable to get the vehicle to go faster than 5-10 mph. I switched to "normal" mode to engage the gasoline engine, hoping this would help but it did not. The gas engine RPM fluctuated wildly and did not restore the ability to accelerate the vehicle. I was still unable to go faster than 5-10 mph. I was a few blocks from home and managed to get home safely. The engine code was P1E00. I put the vehicle on the charger and it seemed fine the next day. This exact situation I ran into - reduced engine power - is addressed in Special Coverage N232432680, which includes this vehicles VIN. I took the car to the GM dealer today and they are telling me that the car is fine, they can find no problems. I mentioned that this issue is covered under Special Coverage N232432680, and was told that unless they can reproduce the issue in the shop, that they cannot apply Special Coverage N232432680.

The vehicle (2018 Chevrolet Volt) is experiencing an intermittent failure of the Battery Energy Control Module (BECM). Diagnostic trouble code P1E5B was stored in the system. This is a well-documented defect in this vehicle population that frequently results in a sudden, unexpected loss of propulsion power while driving ("Propulsion Power Reduced" mode), posing a significant safety risk in high-speed traffic. ​Although a Chevrolet dealership confirmed the presence of the stored fault code, they refused to perform the repair under the extended warranty (Special Coverage N23243268) because the Check Engine Light was not actively illuminated at the exact time of inspection. The manufacturer requires the vehicle to be operated until the fault recurs, exposing the driver and others to the danger of stalling on highways or at busy intersections. The failed component remains in the vehicle and is available for inspection.

Dealer non-Compliance with Recall N192273600 I am reporting Anderson Chevrolet for failure to identify and perform a mandatory federal emission recall while the vehicle was in their possession for service. Because the dealer neglected their statutory duty to perform the free recall repair, I was forced to spend $584.83 at independent shops to diagnose and fix a defect that is a direct mechanical match to the recall repair. General Motors has denied reimbursement, claiming the independent shops repair is ineligible, despite the fact that the dealer’s original negligence created the need for the independent repair. I did call the General Motors Customer Relations department, was told by Breanna a case would be opened and followed up by Angel. No case number given. Angel called the next day and informed me the reimbursement was denied because services were rendered by an independent shop.

It was the XXX recall for the DTC P0442/check engine light code. The dealership said that the recall had been satisfied in 6/2020 by putting a buffer in to separate the 2 lines but not replacing the part. Now the exact same code DTC P0442/check engine light in the exact spot that occurred for the original recall. The dealership originally quoted $5,093, then after me complaining that it is the same recalled problem they dropped the cots to $2384. I believe that is an agreement that the manufacturer should cover this. Of course I will have to pay to get my car but I would like the manufacturer to reimburse me for it seeing it was a manufacturer default. I spoke to the manufacturer they flat out refused to cover it. I obviously disagree. Would like you to pressure them to change their decision.

My 2018 Chevrolet Volt frequently fails to recognize when the vehicle is shifted into Park. The dashboard displays “Shift to Park” even though the gear selector is already in Park. When this occurs, the vehicle will not power off, requiring multiple attempts to move the shifter before shutdown is possible. This creates a safety risk because the vehicle may be left powered on unintentionally and may not properly secure itself in Park. In one occasion, the vehicle moved backwards even when shifter was in Park, which created a collision risk. This is a known defect affecting many GM vehicles, including the Chevrolet Volt, and has been widely reported by owners. I am concerned about unintended vehicle movement, battery drain, and driver safety.

On June 27, 2025, while driving, the vehicle displayed a "Propulsion Power Reduced" warning message and a Check Engine Light illuminated. I immediately experienced a loss of power. I brought the vehicle to an authorized Chevrolet dealer the same day. On July 1, 2025, the dealer diagnosed the failure as a faulty Battery Energy Control Module (BECM) and high-voltage system fault (Code P1E00), requiring a full replacement of the high-voltage battery pack (Part #24296900). The manufacturer (GM) was contacted, and the replacement battery was ordered on July 2, 2025. As of December 2025, the vehicle remains in dealer possession (over 5 months) with no repair completed. The manufacturer has stated the part is on indefinite backorder with no ETA. The failure of this component renders the vehicle inoperable and presents a safety risk due to sudden loss of propulsion power while in motion. The manufacturer has confirmed the failure but is unable to provide a remedy within a reasonable timeframe.

I switched over to battery power but had only approximately 10 miles of range left so after a couple of miles I switched back to engine power and was almost immediately informed by the instrument panel that the engine was in failure mode. Was fortunate that there was an exit nearby and was able to use the remaining battery power to exit the highway and pack the car before there was no power.the car was towed to a dealer and we were told that the egr valve and cooler had failed.they were replaced and I was told that they were not covered by the federal emissions warranty so the cost would be $4000.the car was driven with the vast majority being electric power.

The dealer reported having repaired an emissions recall for a fuel vapor leak, however the repair was ineffective and the vehicle still reports the leak as a fault code "slow" and "fast" emissions leak. The dealer refused to recheck their work without payment. Recently I came into possesion of a borescope camera and was able to photograph the dealer's "repair". The photos clearly show the parts for the emissions repair are located in the wrong place as compared with GM's own service bulletin. Therefore the dealer did not do the repair, or failed to do the repair, and refused to check there own work without compensation when informed of the continuing problems and left me to do their recheck of their work at my own expense. I have provided photos of the GM prescribed parts placement and the incorrectly placed parts in my car as well as the resulting damage. We never experienced the relief intended to be provided by the repair service. They claim to have performed the necessary recall service, but THAT IS A FALSE CLAIM. See Chevrolet TSB N192273600. NOT PERFORMED CORRECTLY SO FAILED. The dealer, Haselwood Chevrolet, Bremerton Washington, was contacted by phone and email but offers no response. They have the pictures of the botched repair job. Additionally the car needs warranty service for a bad park switch which service they refuse to perform without my agreeing in advance to pay for that in warranty repair.

In 2020, GM issued a recall (#N192273600) for emissions pipes on the Chevy Volt that could be compromised by rubbing against the A/C hose connector. I took my vehicle to my local dealership (Chesrown Chevrolet) to have this issue remedied, that same year. This year, my check engine light came on and this same dealership informed me that the cause was this same issue (i.e. a compromised emissions pipe due to rubbing against the A/C/ hose connector). Assuming the fix was conducted per GM's specs, GM did not provide an adequate fix for their faulty design.

Electrically actuated EGR valve fails, it draws too much current and blows the F03 fuse (Labeled “No Walk Home”) which has 4 other components on it, this causes “Reduced propulsion” message, soon after the engine overheats due to one or more of the 3 other components that lost power, and the “Engine not available” message appears and the vehicle loses all motive power. This syndrome is well documented in the GM-Volt online forum. Additionally this vehicle has portions of the EV battery that failed, I am still waiting for battery parts to arrive and its been 4 months, many owners have waited between 1 and 2 years for the battery to be fixed, this contributed to this issue as the electric propulsion would have possibly been available if the warrantied battery was repaired within a reasonable timeframe. I was refused a service loaner. My recent contact with Chevrolet customer service suggested I rent a car, and they will reimburse $45 per day, however they insist I pay for it and when the repair is complete, they will reimburse me. There is a gentleman on the Volt forum who has laid out about $5,000 on rental cars for well over a year, and is finally reluctantly getting a buyback, but they depreciated the car but did separately make good on the rental reimbursement. Neither he nor I really want that result, we want the car repaired in a good faith effort, instead both battery parts and EGR valves are in short supply. Currently the GM part is between $1400 and $2500 when in 2024 the same part was widely available for $240. I understand this is a bit rambling, but the context matters, and GM is dragging their feet on servicing the warranty liability they have. My TZEV warranty is good until 2034 and they are actively trying to kill my car off to save the ongoing cost of servicing this warranty. They are also putting owners at risk. Please consider a battery recall and an EGR valve recall. Regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When shift lever is moved to Park, the car often does not recognize it is in Park and can't be shut down. It takes a lot of time of moving the selector in and out of Park to finally get the car to recognize it is in Park. During an occasion when the car would not go into Park, the car ran for hours while the driver was at work. This seems to be a known issue (micro switch) with this model. This is available for inspection upon request. Safety is at risk because this condition leads to not being able to shut the car down, which leads to the potential for a dead battery and getting stranded. While I have not yet had my car's problem reproduced or confirmed by a dealer or independent service center, there is a lot of evidence in online forums of the prevalence of this problem. The vehicle/component has not yet been inspected by the manufacturer, police, insurance representatives or others. There weren't any warning lamps, messages or other symptoms of the problem prior to the failure as long as we've owned the vehicle. We purchased this vehicle less than a week ago, on August 2, 2025. The issue presented itself once on our test drive and again intermittently in the six days we've owned the vehicle.

On [XXX], our 2018 Chevy Volt experienced a critical BECM (Battery Energy Control Module) failure while being driven by our [XXX] daughter. The failure caused the vehicle to enter limp mode, resulting in a severe loss of power and the inability to shift properly. Most alarmingly, the brakes failed to function correctly—despite being fully engaged, the car continued to move forward at a red light, placing our daughter in immediate danger. She was only able to safely stop the vehicle by maneuvering it off the road into a parking lot. This BECM defect is a well-documented issue for Chevy Volts from 2016 to 2018. However, Chevrolet has refused to cover our VIN under the existing special service bulletin, despite our vehicle using the same faulty part number as those included in the recall, and has provided no explanation for this exclusion. As a result, we are being forced to pay $2,100 out of pocket to replace a part that GM knows is defective. This is an unacceptable financial burden for a safety-critical issue. GM should immediately issue a recall for all vehicles equipped with this faulty part number to ensure the safety of all drivers and prevent further undue costs.

EGR valve failure at highway speed of 70mpg on busy road with passenger and service dog in vehicle on a road trip (on ICE not electric). This produces a reduced propulsion in the vehicle and it becomes unsafe to drive. The EGR failure blew the 15A #3 fuse known as the "no walk home" fuse, so I needed to be towed to a parts store then unplug the EGR valve to make it somewhere safe. It was a Sunday, so every dealership (in the VA area at least) was closed. It is a well known/documented issue and the warranties have been extended, but only in a few states with the CARB protections. There are no warnings, if I was not an adept driver, we could all be dead. I also became stranded ~six hours from my home and only ~eight thousand miles outside of warranty. The replacement part costs ~$1800 without labor - the most expensive EGR valve the 60yr old parts employee at the dealership had ever seen, on a hybrid car which doesn't even truly require the part to operate or to pass emissions in some states. I think GM will help me with a goodwill repair in this case, as I have been a loyal Chevy customer my entire life and Volt owner since 2013 - but that is not the norm, so please take action and extend warranty protection to all Volt owners like the BECM issue.

The Volt experienced a "Shift to Park" error, preventing it from recognizing when it was in park, even when the gearshift was engaged. While this issue was frustrating, it initially didn’t affect the car’s driving capability. I simply had to wiggle the gearshift until the system registered that it was in park. This problem persisted for a month until one day, the vehicle would no longer shift into any mode, though the "Shift to Park" message remained on the dashboard. The car turned on but would not accelerate. The issue was eventually repaired at the dealership, a process that took about two weeks. During this time, we were not initially offered a rental car. It was only after we called and insisted that the dealership provided one while waiting for the necessary parts. This issue appeared to be a factory defect. While part of the repair was covered under warranty, we still had to pay $685 out of pocket.

Yesterday, my daughter was driving on [XXX] in Seattle traveling around 65mph when the vehicle lost power and reported the error of "shift to park", "Propulsion reduced" and "StabiliTrak failure". Luckily, she coasted to an off-ramp and safely put the vehicle in park. Thankfully she was not involved in an accident, but was very shaken by the experience. After doing some research it seems that the Chevy Volt has a known issue with the BECM and GM has failed to issue a recall, putting thousands of lives at risk. After turning the vehicle on and off several times, she was able to get it started and with minimal propulsion on residential streets was able to return to our house. this morning I dropped the vehicle at our local GM dealer for diagnosis and repair, but wanted to file a report, to hopefully prevent this from happening to another unsuspecting driver/child.

The contact owns a 2018 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. The check engine warning light illuminated. Shortly afterward, the message "Reduce Propulsion, Engine will not Start" was displayed on the instrument panel. The vehicle was towed to a local dealer where it was diagnosed with a defective EGR valve. The contact was informed that the EGR valve needed to be replaced. The vehicle was not repaired due to the cost and lack of parts availability. The vehicle was towed to the residence. The contact believed that the cause of the failure was related to high temperatures. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

Driving on gas on the highway, the adaptive cruise control suddenly disabled with a "Reduced Propulsion" message on the dash and a check engine light. The car started struggling in its propulsion. We found an AutoZone and scanned the codes, and multiple were returned. A Google search pointed us to the "walk home" fuse, which indeed had been blown. Replacing that fuse and disconnecting/reconnecting the battery eliminated the errors. Less than a week later during highway driving (the next time the battery charge was used up and it switched to the ICE) I got another check engine light, but this time without the "reduced propulsion" message. Scanning at AutoZone again revealed a P0404 message referencing the EGR valve. Due to the limited availability of the part I have called into Covert Bastrop (Bastrop, TX) and am waiting to hear back on their ability to fix the car.

The issue started with a forward push while lowering my speed while coming to a stop. It then progressed to a trembling engine. Then it progressed to the car struggling to effectively switch from electric to gas and back. It then would only be usable on electric range and the engine would not start and would be greyed out. Now, it only works on engine mode, it uses fuel like a pick up truck, it loses power while driving due to trying to switch to electric mode and back, and it struggles to accelerate. It will do it while idle as well as while driving 45mph and up. It barely has any propulsion power and I have to turn my hazards on any time I am going to accelerate. If I brake hard the engine will shake violently and then shut off. I then have to switch gears from drive to park or neutral to park to drive to reengage the engine. Recently it has turned on all the accessories but the ev and the gas is greyed out and there is zero propulsion power. I replaced the 12v battery thinking it might have been dying and it still has the same issue. I read about the class action lawsuit for the BCEM and have made an appointment the dealership but when I told them what was wrong with it the said we need to wait for the diagnostics.

The contact pulled over and upon an attempting to restart the vehicle, the vehicle failed to restart. Due to the failure, the vehicle was towed to an independent mechanic where it was discovered that the BECM (Battery Engine Control Module) was defective. The mechanic discovered that the vehicle was under warranty and contacted that the local dealer for assistance. The mechanic drove the vehicle to the dealer who acknowledged the failure; however, the dealer stated that the failure was not covered under warranty. The manufacturer was also notified of the failure and the contact was provided a case number. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 100,000.

On [XXX], while driving on [XXX] in Virginia, the check engine light came on in my Chevy Volt. A message on dash said that there was reduced propulsion, and the gas engine quit running. The car switched to battery power, which would not have lasted long enough to get us home. At this point, we were stranded on a very busy highway which seemed quite dangerous. Using battery power, we were able to get off the highway. We then made arrangements to have the car towed, approximately 150 miles to a car dealer/repair business in Frederick MD. The vehicle was checked out by the car dealer who identified the EGR valve as the problem. However, they did not know when the part would be available , and still, 4 weeks later, do not have any date for availability of the broken part.
