What 52 owners told NHTSA about the 2024 Lexus RX 350

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.

I was stopped at a red light with brake on, my vehicle leaped forward on its own three times, with the brake on, the force was so strong I thought someone rear-ended me. No warning lights, the acceleration was load.

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)

On Feb. 10th 2026 I was driving north I405 (Los Angeles). The car suddenly applied emergency breaks in the middle of the freeway, while there was no car in front of me, at least for 100m. I was lucky that the car behind me didn't hit me. It could be a serious multi-car collision.

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”

The rear backup camera does not work when put into reverse

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.

NHTSA ODI 11714118

When accelerating at slow speed, the engine or turbo turns off which causes the nose of the car to take a hard nose dive and then turns back on within 1 second but results in a big loud sound coming from engine/transmission. This issue almost caused on accident because it does a hard engine break where I was almost rear ended but from other drivers perspective, it might seem that I’m break checking them. Showed car to Lexus but they said it is normal but it not normal and should be investigated as it can cause harm to everyone involved if accident were to occur. Situation occurred 3 times this week and it is entirely random and can’t replicate at will.

I went to reverse the car. Suddenly, the car's automatic emergency breaking system engaged. This occurred on 2 separate occasions. The first time, was in a parking lot during a sunny day. There was definitely nothing behind me, not even a person, but the camera saw a leaf or something small, and engaged the automatic emergency brake. The second time, it was raining in the evening, the sky was dark. I went to reverse (to complete a u-turn in an empty lot). Suddenly the automatic emergency braking engaged. In both instances, if I was reversing (as part of a u-turn on a busy street, this would have been very dangerous. Please investigate this. It was very scary.

The car started showing multiple error messages on the dash and then shut off while in operation, it would not restart without a service call and battery boost. This has happened multiple times. Online research shows this is a common issue with the hybrid models - the 12v battery doesn't get adequately charged, voltage drops and car ceases to work - even while mid drive on the road, this is extremely scary and dangerous.

Battery has "sulfated" twice in 15 months of ownership. Lexus/dealer have replaced battery two times. Considered safety issue since battery could "die" at any time. Could be locked out of car with infant inside or if battery dies while driving, car could become immobile.

Heard clicking noise coming from steering wheel. Car shimmied when breaking off of freeway. Newish car, only 20,611 miles. Took into dealership before anything went awry. Dealership said never heard of the steering problem before. Turned out it was a tie rod going bad and repair was covered by warranty. Break issue was also covered by warranty.

Very poor quality front windshield, very fragile. Breaks and chips off very fast even with small rocks which impairs visibility even after repairs leading to replacement of front windshield due to poor visibility especially glare from the sun.

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.

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.

NHTSA ODI 11684200

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.

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.

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
