Failure Date: 11/01/2024

The accident happened when I was using the "brake hold system". It is designed to use when the needs to stop briefly. When the brake hold button is touched while the driver's foot is on the brake pedal, the driver do not need to step on the brake even though the shift lever is in d. After I finished paying for a car wash, I touched the brake hold button. Then the vehicle suddenly accelerated forward and ran at a high speed. I was pushing the brake pedal, when I touched the button. I was startled and attempted to stop the vehicle with all my strength by braking the brake pedal. It didn't stop and went over the cub and accelerated even more and it crossed the both lanes and hit the cub on the other side. It climbed up the bank wall and it finally stopped. The police and the ambulance came and took me a hospital. I later found out the vehicle was towed to a nearby junk yard. I believe that the new high-tech system known as brake hold malfunctioned and caused "unintended acceleration". I believe that it certainly is extremely dangerous. It has not yet been inspected by the Lexus mechanics. There were no warning signs whatsoever before the unintended acceleration. Btw, I have used the function before I. E. When I used drive throughs.

6 Vehicle Speed Control problem of the 2018 Lexus RX

Failure Date: 10/01/2024

1. At [xxx] on [xxx], I was pulling into my gym's parking lot, when I stepped on the break to park my car, instead of stopping, the car accelerates rapidly and crashed through the other side of the sidewalk where there were light pole and cement walls, throwing me forward and backward with seat belt on, I was in total shock! 2. My insurance sent a field inspector to the body shop 2x in hope to repair my car but ended up declaring it a total loss. 3. Lexus said they would send a field tech to get the edr (event data recorder) data from my 2018 Lexus Rx350 within 30 days, but the results won't be available for 30-45 days after that. Lexus's slow response to this accident concerns and disappoints me b/c it was a serious crash that Lexus should treat it seriously and promptly. 4. The disbelief of a 'young' car with only 12297 miles could have issues like this puzzled me and drove me to do a lot of online research, then I came across this site [xxx] which contains an article titled '10 common problems of a Lexus Rx350'. Problem #5 described exactly what had happened to 'one recurring problem this car has is that the system malfunctions severely. This typically happenes when the driver is trying to park the vehicle. Reports paint the same pictures repeatedly: the driver is pulling into a parking lot, they push the break pedal, and instead of stopping, the car acelerates rapidly, which results in a crash. " based on this article, it seems that Lexus should have issued a recall, but no! 5. The strange thing was that no airbags were exploded/activated, yet the vehicle was damaged to beyond repair, it makes me wonder if there was an issue with the airbags too. If this incident had occurred at an intersection, I dare not imagine the outcome. . . I could have been killed or critically injured along with other innocent people on the road. I am very traumatized by the whole experience and sadly, the feeling seems to have gotten worse as time goes. Information redacted pursuant to the freedom of information act (foia), 5.

October 20, '23 our recent dead stop! whistle blower! did you know that when the alternator goes out on a Lexus, that the car draws down energy from the battery to keep the car going? that's only for about a mile or so, then the car shuts down! you can't steer and the engine stops running and you have no power as you come to a dead stop, whether on the freeway, or one lane mountain pass road, where we would have been later. What would we have done? scary! luckily, our Lexus stalled on a city street nearing our on-ramp to the freeway. (needing to be towed. ) Lexus has a serious engineering-defective-design-flaw that probably is responsible for accidents. Thanks, doug. Pass it on pleas!.

16 Vehicle Speed Control problem of the 2020 Lexus RX

Failure Date: 08/10/2021

Was driving into the garage (coasting) very slowly and as I was preparing to step on brake the car revved forward unsuspectedly - I have a video on my ring door bell and you can hear the engine then the squealing of the automatic braking system. I destroyed the adult 3 wheel bicycle that was stored along the wall but that helped the vehicle from crashing through the bricks - I remember shouting “what the hell is happening”. After much research as I knew I did not depress the accelerator in error - I found that this has been a common occurrence with Toyota and Lexus products. I am a very careful driver and I have replayed the incident in my head over and over. I presently dont have the insurance and repair information readily available.
