We are or have been very loyal Toyota and Lexus owners for many years. Our 2010 RX 350 was an upgrade from the 2006 IS 350. The Vehicle is a great ride except for the unintended acceleration.
It came very close to tragedy 2 weeks ago on an interstate. I have heard about the Toyota problem but didn't want to believe that it would happened to our RX. There is less than 20k on the vehicle. It started acting up a few months ago, it would accelerate over set cruise speed by 10 miles hr but wasn't life threatening, braking stop the acceleration. This happen twice with me & twice with my wife until the brake didn't stop the problem acceleration. She couldn't get it stop by jabbing the brakes hard,
The Rx has great comfort just bad acknowledgement of the unintended acceleration.
Fix the problem. It is real. It is not driver error or floor mats. My wife is still alive. When you buy a Lexus you shouldn't have to worry if its unsafe.
