2024 LEXUS RX Complaints

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.

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

Brand new vehicle- 12volt battery failed after 5 weeks. Lexus initially stated battery fine. Then battery failed while in their possession- Lexus replaced battery. Few weeks later battery failed again. Lexus tested & replaced battery for second time - but battery kept draining & they were unable to repair after having vehicle at dealership for 3.5 months

This car is a hybrid. it is 15mos. old w/13500 miles. I've had two 12v battery failures which resulted in 1 time being locked out of car, and 1 time locked in.

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
