Unintended acceleration
 

I am wondering if anyone has experienced unintended acceleration with their LX570. On two occasions, I drove over a very slight speed bump and the car accelerated without my foot being on the gas. It felt like the automobile hydroplaned even though the road was completely dry and clear of debris. Lexus has looked at the vehicle and cannot replicate what happened. I am afraid to drive the car due to my obvious safety concerns. (The mat was not the issue) Thanks!

Unwelcome Hard Acceleration with Adaptive Cruise
 

I get the "unintended" "unexpected" "unwelcome" hard acceleration when the adaptive cruise control tries to come back to the set speed after having slowed down due to a car in front. This is scary but I dont think Lexus has a solution for this (yet). I've had the adaptive cruise in Porsche & Mercedes and when it needs to accelerate back to the set speed it does that in a dignified, calm and gradual manner. The LX just downshifts like crazy and tries to reach the set speed in a wild manner. Not cool!

I have experienced an unexpected acceleration on my 2010 LX. Happened, when I pressed and released brake pedal. This occurred a few times already. The only problem is to re-produce the issue at a dealership.

That is exactly what happened with mine, tella. I noticed it after releasing the brake after going over the speed bump. I took the dealer to the exact spot where it happened on Friday and was not able to replicate it. Was wondering if it had to do with the ABS getting messed up somehow. Do you recall the road conditions?

Very scary, 03, I don't use cruise control much, but I will be extra cautious when I do due to your warning. Be safe!

Did either of you call in Lexus Corporate Customer Satisfaction? I did...not so impressed.
