2021 Lexus RX 350. My husband and I have each driven a Lexus RX 350 since the mid 90's without a single issue. I bought a 2021 RX 350 i November, 2020. In October, 2021, my friend was driving it on a road trip in Hot Springs, AR. Long story short, as we sat waiting to join the traffic the car just sped off by itself at full speed, causing a fault accident. At the time, I thought my friend had just had some sort of mental lapse. However, in January, 2022, the identical thing happened to me. I filed a complaint with my local Lexus, Austin, TX. It was inspected locally, and the only feedback that I got from the October accident was that "your friend must drive with two feet", which she absolutely does not!! Then, I had to submit a mountain of paperwork to Lexus corporate. In April, they sent a gentleman (3rd party person) to inspect it. I got nothing but a bunch of symbols from him. I received an email as my formal response to my complaint, stating "no accident found"! I guess there wasn't; they had the wrong date for the date of the accident!! I have been lied to, jacked around all over the place, and they won't even return a call now. Additionally, ever since I've owned the car, there is a place in the seat that pokes me; it's never been an issue until this past week when I ended up with sciatica. I won't bother taking in it, because they will just say "nothing found"! Worst of all, I am legally obligated to disclose the unintended acceleration when I sell the vehicle, which will be sooner rather than later, as I am very nervous driving it after the incidents of UA. I will never purchase another Lexus ever!! There is something very sinister going on. Buyer Beware!!

Why don’t you report it to NHTSA?

Thank you for the great idea. I'm definitely going to do it. Also, they took it down! Isn't that special?!!

Took what down?

Why didn’t she just floor the brake pedal?

Exactly. There is no scenario possible where slamming on the brake won't stop the car, even if you have the gas pedal pinned to the floor simultaneously. There is no such thing as unintended acceleration. It's driver error.

If it were me i would trade it in ASAP.If anything you would feel safer.

Things like this has happened on older RX's and toyota has addressed these.

One thing I noticed is that the poster is new and has been driving an RX350 since this 'mid 90s'. Is this a typo? First RX was a 300 for 1999. Could this be clickbait? Maybe some clarification from the poster?

Not true. The engine will overpower the brakes

Not with the current ECM software. I've tried it in the wife's 2016 GS F, and you immediately get throttle close and a warning on the combination display that both pedals are being used. My '08 IS F never got the software update because I refused it so I can still left foot brake to rotate the car at the track. Can't ever do this with any Lexus after '08.

And by design, the engine will not overpower the service brakes until they overheat and fade. It's a global automotive standard.

OP is a troll.

Correct. Lexus retrofitted my 07 IS 250 by a recall after the "runaway" ES in the mid 2000s that had the gas pedal trapped under the floor mat. After the recall, even if I lightly tapped the brake with my left foot while my right foot was on the gas pedal, the car would noticeably start to slow down.

Oh yeah, I forgot Toyota is stupid like that on stock programing. Sucks since they applied it to everything, you would think they would have left the F cars or any of the RWD cars alone. It's not hard to go to N if something happens after all...it would also make brake boosting impossible as well.

I'm not so sure about that second one, I have been able to overpower the brakes in many cars before they are sent to scrap to see if they can do it. Might just be due to age but if you stand on the gas and brakes the brakes usually lose.

NHTSA investigative staff review complaints. Complaints are not taken down unless bogus.

Can you provide NHTSAs reason for taking down your complaint?
