• 12/06/2024· POWER TRAIN

  While driving on a local highway recently, my forearm brushed the automatic shift knob while reaching to place my phone on the wireless charging pad. The transmission shifted into neutral, resulting in an unexpected loss of speed. It took me a few seconds to realize what had happened - I shifted back into Drive, and resumed my trip. No accident resulted from this, but it has happened twice in the month that I have owned the car. I reported the issue to the dealership thinking my car had a problem - they said that this is the way the car is designed to function. I found a section in the Owner's Manual which confirms this - shifting from Drive to Neutral while stationary requires the knob to be held to the left for a couple seconds; for some reason, doing this while moving requires only a tap (see attached photo of the owner's manual). This seems like a design issue - the unexpected loss of power from bumping the shift knob to the left (no forward or backward motion is needed) could easily result in an accident. I don't understand why they specifically created a system where a "push and hold" is not required to shift into neutral when the vehicle is moving. I reported this issue to corporate Lexus today. They said they will consider this feedback in subsequent model designs, but I wonder whether a recall is appropriate. That's why I'm reporting the issue to you, as well.

• 11/26/2024· STRUCTURE

  The material (most likely) plastic used as a trim on the vehicle is melted or started to melt. This is the trim (b-pilar) between the driver's door and the rear passenger's door. We believe the quality of the material used for the trim is defective and should be addressed by the manufacturer.

  Was pulling into parking spot when car went haywire and started accelerating on its own. It would not stop until it has hit 5 cars and crashed into a cement wall. The brakes did NOT stop the acceleration. This occurred at the exact same time there was an incoming call which was not answered. The airbags did NOT deploy. The car appears to be totaled and has been towed to a State Farm affiliated auto yard. There were no indicator lights that something was wrong BUT the Lexus app showed 5 warnings that came in to my text messages same day. These 5 alerts are indicative of exactly what occurred.

• 09/03/2025· ENGINE

  When we purchased this car in June 2024 it did not have an engine revving issue. The engine, electrical or transmission maybe all of them have SERIOUS SAFETY ISSUES! When driving and you let off the gas pedal the engine starts revving very loudly, it scares the heck out of you because you don't know if you can stop! I have a serious mechanical background, there is always the possibility of the transmission not disengaging and forcing the car NOT to stop! This issue is VERY DANGEROUS AND SCARY! We get very nervous driving a car we paid almost 70K for! Yes reported to the dealer Mungenast Lexus of St. Louis, yes they have duplicated the issues. After keeping our car now on two different occasions for weeks at a time they went to Lexus engineers who are now trying to say its normal! if so, why didn't it start doing the revving until there were thousands of miles on the car! THIS IS A COVER UP! Not been inspected by the manufacturer yet, they only spoke with them. No reason for police or insurance yet. No, there has never been a check engine light appear. The only other thing the car did, after the first time of it revving like this it died when we were pulling out in traffic, it didn't die it actually shut off! This has only happened the one time, it shutting off, can it do it again you bet! These cars are dangerous, I hope nobody has to die to prove this!

  Lexus RX Sunroof exploded on it's own. I just left my driveway and was the only vehicle on the road. There were no projectiles, the sunroof glass simply exploded and glass flew into the air. if I was driving at 60 MPH, the exploded glass would have become a projectile and could seriously hurt a bystander. They were no warnings. I filed a complaint with Lexus Reference # 250820001020 but their response was that this was not a mfg issue. I pointed out that they are two class action suits on Lexus, but they insist that this is not a recalled part. This is a safety issue with glass flying at 40 to 60 MPH in the open air.

• 08/25/2025· UNKNOWN OR OTHER

  While driving on the freeway the sun roof "exploded" shattering glass out onto the highway. The noise was loud and frightening. Upon pulling over I observed most of the sunroof was gone with fragments of glass remaining along the edges of the roof. I believe this to be a major safety issue. If the ceiling cover had been open, the passenger in the rear seat could have been seriously injured. No doubt flying glass is a danger to any cars following. The vehicle was inspected by the Lexus dealer who declined to cover the damage under warranty. My insurance (CSAA) agreed to pay the cost of replacement. The glass shop which did the work indicated this is a manufacturing defect and indicated they replace 5-6 sun roofs a week.

  gas gauge very inaccurate. manual calls for 'low fuel' at 2.6 gallons, actually comes on between 7 -8 gallons left in tank. Dealer accepts it is a problem but has no solution. attempting to get full range may leave car out of gas on highway, since gauge cannot be trusted.

  While on a long road trip on a hot day, on the interstate, the car suddenly lost speed and would not accelerate. It was like the car had shifted into neutral. I was coasting on the interstate, steadily slowing, and was forced to pull over to the shoulder. I turned the car off and waited a couple of minutes then turned the car back on. No error messages were displaying at that time. About 5-10 minutes later, I pulled over for a planned stop. My husband assumed driving responsibilities when we got back into the car. Upon trying to get back on the interstate, the car would not accelerate, and multiple errors error messages appeared, including: ""System Malfunction/Visit Your Dealer," "Check Engine/Visit Your Dealer," "Drive-Start Control Malfunction/Visit Your Dealer," "Secondary Collision Brake System Malfunction/Visit Your Dealer," and "Traction Control Turned Off." He pulled into a nearby parking lot where we had to have the car towed to the dealership. It felt like the car was in neutral when this happened both times.

  We live on dirt road in Kansas, and must drive 2.5 miles to get to paved road. This RX 500h Sport does NOT have proper gaskets around the doors. We can actually see dust rolling into the front and back doors as we drive. We have had numerousLexus RXs,& GXs over the years and never experienced a dust problem at this level. Again, we can actually see dust clouds entering the car as we drive down our daily 2.5 dirt road trips.

  We just pick up this car last week from the dealership here at San Antonio. TX. As we were driving there is a downpour/rain due to hurricane beryl, turn on the wiper and did not work, just got stuck in the middle of the windshield. i almost got hit on the road because i can see in front of me. Maybe it is also my fault by not checking this things before i drove off. At this moment the car is back at the dealership and my service advisor says that the motor is defective and they will order the parts.

  I experienced a sudden release of toxic fumes from the vehicle between the steering column and instrument panel area on June 29, 2025, while driving. The fumes struck my face, caused immediate bitter chemical-like taste and made me feel physically ill and extremely concerned for my safety. The fumes were strong enough to leave a lingering taste described as “bitter and green” with initial symptoms of headache, lightheadedness, nausea, vomiting green substances, eye irritations, nose and throat irritations. The local auto dealership inspected the vehicle, no mechanical defect was identified, and they noted that they cannot reproduced the event that led to the release of the toxic fumes. However, the vehicle manufacturer took possession of the vehicle for 1 week to conduit further inspections

  I have purchased a new Lexus RX 350 2024 from South County Lexus in Mission Viejo in March 2024. Upon completion of the purchase, I was informed that I get only one key for the car as there is a shortage of the keys. I was told that it will take a few months to get a 2nd key. Now it is June 6, 2024. I called the Lexus dealership as well as corporate office. I was informed that I probably will get the key in August 2024. I find it absolutely unacceptable. It creates a safety hazard when a 2nd key is not available.

  From last month, I am receiving a lot of messages on my IPhone that multiple rear doors are open, please check the doors. Over night RX2024H draining the Battery and a lot of time it shows on screen red. Today again it showed only close to 20% charge left. I took the RX to Roseville Lexus and they perform 10K miles service and advise me that this RX350H has issues with the notices sending to owner's cell phones. They advised me to delete my account and logoff on my cell for Lexus App. Now I am driving on GUEST Mode and it still has the Battery issue it is draining over night or when parked in the garage. Chris Lawson at Roseville Lexus told me last month that RX350H has this issue and when battery is dead and car won't start and they called the Lexus service and they sent the AAA and AAA guy. Some of them got more issues and Lexus is not covering it under warranty. When, I called Chris that my batter shows RED on charge and he said, if I want them to check the car dealer will charge $219 for trouble shooting. Please look into it and Lexus should fix the issues in their cars or fix the issues in the applications. it is not safe for driving. Any questions please call Chris Lawson at 916-472-7445 for more information. I have the pics but not able to attach to this complaint

  Lexus is still not providing 2 key fobs on delivery. They are not listing the 2nd Key Program (23LJ01) as a campaign on their vehicle mobile software. The "digital key" is glitchy and not a safe and secure option - it seems to be a way for Lexus to periodically generate more profit at the expense of customer safety and security.

• 04/14/2026· LANE DEPARTURE

  When in cruise, the car will merge itself into the next lane if you hold the turn signal partially. If you keep holding it or fully engage the turn signal (maybe you forgot to turn off you signal, or held it too long), the car will merge through the solid white line off the road into a ditch. This happened to me once, and I noticed it trying several other times.

• 03/07/2026· ELECTRICAL SYSTEM

  I am reporting a recurring electrical and mechanical system failure on a 2024 Lexus RX 350h Luxury. On [XXX], the vehicle suffered a total power loss that rendered the electronic door latches unresponsive to all inputs. Because the occupants were a [XXX] and a [XXX] strapped into car seats, they were physically unable to reach the interior manual overrides. Critically, the mechanical backup key also failed to unlock the vehicle from the exterior, preventing immediate rescue. This created a life-threatening entrapment scenario. The doors only responded after multiple minutes of repeated manual attempts. Once entry was gained, the vehicle would not start and the headlights began blinking rapidly, indicating a total system communication failure. I had to use jumper cables to restore power. This is the second occurrence of this catastrophic failure, documented on Repair Order [XXX] at Lexus of Westminster. The failure of both electronic and mechanical failsafes constitutes an extreme occupant safety hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  I am writing to report a serious safety issue involving my Lexus RX350. While driving on the freeway with my [XXX] child, I suddenly heard a loud explosion-like sound coming from the roof. To my shock, I discovered that the sunroof glass had shattered into pieces. Fortunately, the sunroof cover was closed, preventing glass from entering the cabin and potentially causing severe injuries. When I contacted my Lexus dealership, they acknowledged that another GX had come in just the previous week with the exact same issue. They insisted that a rock was the cause. However, I find it extremely concerning that a small rock could cause such catastrophic failure, indicating that the glass material may be dangerously flimsy. This incident has left me deeply shaken, as it could have resulted in severe injury or even loss of control of the vehicle. I am afraid for my safety and that of my family, knowing that this could happen again. I urge NHTSA to investigate whether this is a defect in the sunroof design or material quality, as it poses a significant risk to drivers and passengers. Please let me know if additional details or documentation are required. I appreciate your time and attention to this critical safety matter.

  My 2024 Lexus RX 350h experienced a catastrophic 12V battery collapse (2.00V), disabling the electronic 'e-Latch' door system and rendering interior handles non-functional for standard use. While a manual override exists, it is not intuitive for emergency egress. Additionally, the electronic parking brake and shift-by-wire systems remained physically locked, preventing the vehicle from being moved to a safe location during the power failure. I am reporting this as a failure of primary safety and fail-safe protocols. Dealer did not consider this a a problem because he said I “needed to read the manual before I ever drove the car”

  When coming from a stop, the car will not respond to the gas pedal being engaged OR it will begin to engage and then no response leaving the car rolling for a few seconds until a response is recieved and the car engages again. This has caused us to be put in harms way MANY times with oncoming traffic when making turns or in front of oncoming traffic in intersections. The dealer states this is not a known issue however it is all over the internet that hundreds of reports of this issue have been made. The dealer states no fix since they don't "have a problem". MAJOR safety issue. We have reported this many times to Lexus now with no resolve or help from them.

  When I start to coast to come to a stop the engine will rev, even though the Energy Flow screen shows the gas engine is disengaged and running only on EV. The engine will rev, even with me using the brake. But the EV light is off and the rpms are rising. Eventually the EV light will come on and the gas engine will cut off and the vehicle will switch to EV mode. My mpg has dropped to 36.2, so something is not right. When I was at the dealer for my 10K service, they told me this was the car "shedding" the extra energy, but the battery was not fully charged, so I'm perplexed and frustrated.
