Summary of Issues: 1.On March 3, 2026, I contacted my service manager regarding my inability to open the driver’s side door. I also reported persistent rattling sounds coming from the interior panels and driver’s side door, extending toward the rear of the vehicle that leads to the gas cap door. I was forced to enter through the front passenger door. 2.On March 4, 2026, I dropped my vehicle off at Lexus service department. My service manager got into my vehicle and was unable to exit through the driver’s door. This presents a serious safety hazard. I expressed concern that the issue could be electrical in nature; however, I was advised that new door locks were needed. 3.On March 10, 2026, my vehicle was returned to me after being serviced, with the explanation that both front door locks had been replaced. I questioned why the passenger-side lock was replaced, as I had no prior issue with that door. 4.After picking up my vehicle, I traveled and left it parked at Austin Airport until 3/15/2026. Upon my return, I experienced the exact same issue-the driver’s door would not open. 5.On March 16th, 2026, I returned the vehicle to Lexus service department for further evaluation. This repeated inconvenience has been time-consuming and frustrating. As this is a luxury vehicle. 6.On March 18, 2026, I was notified that my vehicle was ready for pickup and was told the issue was related to the door bezel. Upon retrieving my vehicle, I immediately noticed that the driver’s door lock was visibly missing. I returned to the service department and documented the issue with photographs. I was then informed that the driver’s door panel would need to be replaced. Later that same evening, while attempting to refuel my vehicle, I encountered difficulty opening the fuel door. I again heard the same rattling and popping sound extending toward the gas tank. At this point, I am concerned for my safety and do not feel comfortable operating this vehicle.

My vehicle is experiencing a mechanical failure of the brake actuator/booster assembly, manifested by a "squawk/bark" noise and abnormal pedal feel during braking. This is a known defect recognized by Lexus under Customer Support Program 23LE04. The dealership technician confirmed the noise is present and recommended a full replacement of the ABS actuator. However, Lexus is denying coverage because the onboard computer has not yet triggered a Diagnostic Trouble Code (DTC). By denying the repair, Lexus is requiring me to operate a vehicle with a confirmed mechanical brake malfunction, which increases the risk of a crash, increased stopping distance, or total brake power assist failure. March 2021 (60k miles): Actuator was replaced under warranty for this exact failure. December 2021 (74k miles): The failure recurred. Lexus and the dealer refused to cover the diagnosis/bleed, forcing me to drive a defective vehicle. February 2026 (110k miles): A Lexus dealer confirmed the part is failing again and quoted $3,000 for replacement. Despite a manufacturer program (CSP 23LE04) existing for this exact part, Lexus refuses to honor it without an electronic code, even though the mechanical failure has been physically confirmed by their own technicians. The component is available for inspection.

My vehicle has 39800 miles (64k kms). I have the exact same issue with my driver side heated seat. The lowest setting may take time to warm up then gets scorching hot. Eventually after heating it up, I will turn it off manually to stop heating it, as it burns. My wife also mentions that the passenger side as well doesn’t seem to heat much. At this low of kms, I should not have this issue but saw someone else have the exact same issue. I have not taken it to the dealer yet as I fear they will charge a fee just to verify the problem. I have an old ES300 and I do not have this problem with the heard seat. My trim level is also the ultra luxury.

My vehicle, a 2017 Lexus RX 350 with approximately 111,872 miles, experienced a near-total failure of the infotainment/navigation screen approximately five months ago (around June 2025). The system would only display the introductory safety message, backup camera feed, a single radio station, and basic map locator functionality—rendering the navigation, full audio controls, climate integration, and touch interface inoperable. This issue severely impacted the vehicle's usability and safety features, forcing me to seek immediate professional service.

NHTSA Safety Complaint – Seat Heater Defect Vehicle: 2017 Lexus RX 350 Mileage at purchase: 45,430 Purchase date: Feb. 17, 2025 Dealer: Lexus of Tacoma at Fife, WA Description of Problem: The driver’s seat heater does not function properly. It is slow to activate (5–6 minutes), then overheats uncontrollably even when set to “LOW.” On multiple occasions, the seat became hot enough to cause burns through clothing. Defect Confirmed by Dealership Service Staff: Dealership staff confirmed that the driver and passenger seats heat at different rates. This matches a known defect identified in Lexus Technical Service Information Bulletin L-SB-0038-18 (Oct 10, 2018). Additionally, they confirmed that the drivers' seat spikes to uncontrolled high temperatures, even on the "LOW" setting. Despite this, the dealership refused to repair the issue without an extended warranty and suggested using a sheepskin seat cover to prevent further burns, which is prohibited in the vehicle manual. Safety Hazard: •The defect caused burns to the driver. •The driver's elderly mother, who has peripheral neuropathy in her legs, did not feel when the passenger heater was accidentally turned on, highlighting the risk of undetected burns should the heater defect remain unrepaired. •Risk of fire is also present given the uncontrolled heat and inherent electrical issue. Attempts to Resolve: Reported to dealership on 3/28/25. Dealer disclaimed responsibility. Reported again to dealership on 6/25/25. No response. Reported to Lexus Corporate Customer Service on 8/28/25. Summary: The seat heater malfunction is a confirmed manufacturing defect, already documented by Lexus in a TSIB. Not mentioned in the TSIB is the additional problem of uncontrolled heat spikes, which poses significant risk of burns or fire. Request NHTSA investigation and corrective action.

3 months before the accident the power steering light came on twice and went off. The day of the accident the brake light came on when I started the car that day. It disappeared when I was put in drive. I was entering onto the highway to merge with the traffic. Another car waiting for the light to turn green so he could enter also. My car didn’t stop because my brakes failed and the collision avoidance system didn’t work either. No sounds nor warnings. I have photos of the message that was displayed on the dashboard.

My car has an oil leak from the timing chain cover gasket that was discovered by an independent mechanic at 37,465 miles. The dealer confirmed the leak on June 14, 2024 during a recall replacement of the fuel pump. The repair is very expensive and the car is no longer under warranty. This is the second occurrence of this same issue. The first occurred in April 2021 at 24,192 miles and was repaired by the dealer under warranty. There were no warning lamps or messages of the problem but there was oil on the ground where I park. The car is available for inspection. An internet search confirms that this is a known and common problem with the Lexus RX350 (and specifically the 2017 model) for many owners with some occurring more than once as in my case.

I bought this car in March 2020. We took it to the Kingsport, TN Lexus dealer Sept. 14, 2020 for several warranty issues and a recall factory interior front door handle replacement. Today, 9/3/24 the front driver’s side interior door handle broke and the door cannot be opened from inside the car. Called local dealer who said that it was guaranteed for 12 months or 12,000 miles. I find this completely unacceptable. I am [XXX] and have driven cars for over 40 years and I have never had a car handle break. For this handle to basically last four years is unacceptable and unsafe for any Lexus driver. At this point I question as to whether the repair was actually made. If in fact replaced, I am shocked by the lack of quality in a repair that was to have fixed a serious issue. Driving a car when you cannot open the door is not something I recommend to anyone! I have called Lexus National customer service and they have opened a case. I do plan to have this repaired and I do not plan to pay for what I consider to be very low quality part replacement.

When checking the emergency SOS function in my car I found that it did not work. I called Lexus support and was told that the following safety systems would no longer be operative: Lexus Enform Safety Connect including Automatic Collision Notification; Enhanced Roadside Assistance; Emergency Assistance Button and Stolen Vehicle Locator; Lexus Enform Remote including Remote Engine Start/Stop, Door Lock/Unlock, Vehicle Finder, Guest Driver Monitor, Vehicle Status and Alerts, Key Fob Remote Start, and Integration with Alexa and The Google Assistant; Lexus Enform Destination Assist including 24-hour live response center agent; Lexus Enform Service Connect including Vehicle Health Report, Vehicle Alerts, and Maintenance Alerts; These include safety systems that I rely on, especially when driving on interstate highways, and were included when I purchased my car. I had no warning that the services would cease to function in October of this year. Lexus states that these systems will no longer function because telecommunications providers will no longer support 3G service. This is certainly a safety issue for me and for other drivers and I believe that Lexus should be required to modify the hardware/software in these vehicles to function in a 4G/5G environment. Lexus representatives state that Lexus has no plans to correct these safety issues. I am requesting that NHTSA review this matter as a highway safety issue.

The shattered glass fell into the vehicle and left a huge hole in the center of the glass panel. My safety was at risk due to explosion of glass while driving at an elevated rate of speed of 75mph. All while traveling over 100 miles from home and then having to drive the vehicle home with a gapping hole in the roof. The surrounding drivers were also at risk due to the glass flying off and hitting their vehicles. There were no cracks or failures to the glass prior to the glass exploding.

During a routine maintenance at the Lexus dealer where vehicle was purchased, we were told that there was a potential oil leak from ("potentially") the engine where the block, cylinder head, and timing cover components meet. The quote we got for the repair is $18,781.52 as a good portion of the car needs to be disassembled to access the motor. This issue was only brought up after the warranty expired. The Toyota 2GR-FKS 3.5L V-6 engine in this vehicle is known to leak in this area due to the gasket mating surfaces in the area mentioned above not sealing completely requiring silicone RTV caulk to be installed during engine assembly. If this is not done correctly leaks occur. Lexus refuses to make good on this saying the car is out of warranty. Ironically, after receiving the quote from the dealer for the repair, we received an offer to extend the warranty - available only after this $18k repair was completed.

•What component or system failed or malfunctioned, and is it available for inspection upon request? Amplifier is in failure. There is no sound. This is a very common problem with Lexus. It is available for inspection upon request. •How was your safety or the safety of others put at risk? (1)Navigation and Directions – Navigation is working properly, but no sound coming out from navigation. This could lead to confusion and distractions. I have been using my phone to navigate, and this is not safe using my phone while I am driving. (2)Distracted driving – There is no sound using Bluetooth, so I disconnect my phone with the car’s Bluetooth. When I receive a phone call, I have to check the phone to see if this is an urgent call, like calling from my son’s aftercare. If the call is urgent, I have to respond to the call. This doesn’t allow the driver to make hands-free calls. This can lead to distractions that compromise the driver’s attention and increase the risk of accidents. •Has the problem been reproduced or confirmed by a dealer or independent service center? This issue was checked by Lexus Englewood Service center, and they confirmed that this is the amplifier failure. I purchase this vehicle at Englewood Lexus. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? This issue was checked by Lexus Englewood Service center, and they confirmed that this is the amplifier failure. •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

The lane departure camera is mounted to the windshield and the glass between the windshield and the camera becomes fogged over time. This results in the lane departure system becoming less sensitive or inoperable - in particular in low-light or when sun was shining toward the camera (dusk/dawn). It also results in the adaptive cruise control becoming more erratic (abrupt in stops). This design puts the user of the vehicle and others around them at risk as key safety systems are compromised. This is in an area that is generally not easily accessible for an owner to clean. However, I was able to remove the camera and clean the glass (please see pictures) and normal function resumed immediately. This is not an operation a owner should attempt and there are warnings about camera re-calibration. I believe NHTSA should consider this a design defect that could be cured by a visit to a dealer (periodically) with their technicians performing a complementary cleaning of the interior camera glass to ensure the camera continues to function properly. About the car: This car has never been in an accident, non-smoker, always garaged (no sun/heat exposure) driven in the city with no dust or debris in the cabin (exceptionally clean inside and out) 33,500 miles at time of cleaning (photos attached). I believe this fog is due to off-gassing of cabin materials that occurs naturally as the vehicle ages.

I purchased a 2017 Lexus Rx 450h Fsport last year at Carmax. About 6 months ago, I noticed that every time I pressed the brakes, there was a chirping sound. I figured it could be dust in the calipers. As the months went by, the chirping sound has gotten louder and now it affected the parking brakes. I researched this problem and many people online have also complained that they are hearing this Chirping sound or what the Dealer calls a "Brake Squawking" sound. I received a letter from Lexus saying to bring my vehicle in for a possible Brake Booster and Fuel pump failure. So I brought my car to the dealership. Since it's there I complained about the chirping sounds that it's making every time I step on the brakes and when the parking brake is applied. I told the Advisor at Lexus that a lot of people online have also complained about this problem and it should be a "Recall". He said that it's not a Recall. To make the story short, the Dealership didn't find anything wrong with the Brake Booster and the Fuel pump. What's causing the Chirping or Squawking sounds was the "Brake Actuator". I was quoted $4,327 to have these parts replaced because my Rx was already past the 50,000 miles warranty. I brought my Rx to the Dealership at 55,483 miles. It was a great thing that we purchased the extended warranty at Carmax called the Max Care which I only had to pay a $100 co-pay. Amazing! It took about 2 days to have this completed. Now, the chirping sound has disappeared when I press the brakes and when the parking brake is applied. I truly believe that this should be a Recall by Lexus and be covered. It shouldn't matter how many miles the customer has. This is a safety issue. The brake actuator shouldn't fail this soon. I have a 2007 Lexus GS350 with 225,000 plus miles and I never replaced the Brake Actuator. I don't know if even has one. The bottom line is when I press the brakes on that car, there were never any chirping sounds.

It was found during inspection of front break calipers that rubber dust boots on 3 out of 4 pistons (2 pistons per caliper) were torn apart. Chunks of cut out rubber boots were found inside the pistons. The car never had break work done since the time it was manufactured. The brake pads on both front wheels are still factory original. The only way for dust boots to get damaged is to have improper installation during car assembly process where rubber boot is not tacked fully inside caliper. The issue would result in premature wear of piston seals dust boot supposed to protect. Wearing off seals would result in leak of break fluid and potential sudden loss of break functionality. The workmanship issue is likely to be impacting other vehicles assembled on the same factory floor by the same employee.

On 5/8/2020, Northtown Lexus replaced or repaired the vacuum pump. Northtown Lexus required the vehicle to be returned for repair twice, following the initial repair on 5/8/2020. After three attempts, the vehicle's vacuum pump (per a factory recall) is not functioning properly. Northtown Lexus refuses to further diagnosis this defective vacuum pump and continued to decline any and all requests for repair. The vehicle operates abnormally ever since this factory recall was originally addressed by Northtown Lexus on 5/8/2020.

Sunroof Glass Failure Report: I was traveling on the interstate at the speed limit and there was a loud bang, which after I pulled over, discovered that the sunroof had "exploded". There was no sign of anything hitting it and the weather was typical for the Texas Gulf Coast in a July morning. Luckily, the underneath cover for the sunroof was closed, because several pounds of glass fragments were released in the sunroof failure and would have been all over the passenger compartment of the Lexus. This is a major safety issue, especially if a child is fastened in a car seat with this problem directly overhead. This issue has been reported by numerous other Lexus owners and seems to occur often enough that it should be a concern for the manufacturer, but I am not aware that they have taken any action on this. A photo of the failed sunroof is included.

Today, May 5th approximately 9am travelling on 287 East (Westchester County, NY) I was startled by what sounded like an explosion - I literally ducked in the driver's seat. Sounded like it came from overhead and then I observed that no other car seemed to have slowed or was affected. I put on my hazard lights and drove a 1/2 mile or so until I could safely pull over. As I'm driving I can hear over my head rumbling and the wind as if the sunroof was open - but I hadn't opened it. When I was able to get out and take a look the closed sunroof had shattered outward - it reminded me of a volcano pattern. Left my hazards on, got unto local roads and drove car to dealer - Ray Catena Lexus of White Plains, where we purchased the automobile. Service told me something must have hit me at the right angle. They could find no debris besides broken glass in the sunroof compartment. I was shaken and went through the process of figuring out a loaner and cost to repair. Upon my return home I spoke to my husband and we realized it just didn't make sense. We started doing research and discovered that the Toyota corporation may well be aware of these incidents, they've been happening to different models of Lexus cars/SUVs for years - different models all over the country. In California there is currently a class action suit against the corporation. I'm thankful I was driving and not my daughter and that I had the presence of mind not to lose control of the car or open the soft inside cover of the sunroof. This needs to be investigated, Toyota makes many different model cars, trucks, SUVs and this is unacceptable. My one regret is that I didn't have the presence of mind to take a photo.

I was involved in a side collision accident and my car was determined to be total loss by the At-Fault's insurance company. I was lucky that my son and I came out with bruises and a few scratches but the main problem here is the airbags. It DID NOT deploy at all when it was hit. The force hit us from lane 1 all the way to lane 3 and damages to the structure near cabin was found by one of the vertified accident body shop. So yes, no airbags were deployed.
