Accelerator stuck open and had to apply brakes which kept me moving forward in a skidding motion on freeway; luckily I didn't hit the person in front of me as I applied both feet on brake pedal sending the car skidding in a breaking pattern! accelerator finally released.

The contact owns a 2006 Lexus IS350. The contact was driving approximately between 35-45 mph when the vehicle accelerated up to 90 mph without warning. The brake pedal was depressed to the floor with extreme force. The vehicle failed to slow down. Immediately, the emergency brake was engaged and the vehicle slowed down.

The contact received conflicting information from the dealer and manufacturer with uncertainty of the floor mat installation. The failure has not recurred. The failure mileage was 44,000. The current mileage was 65,000.

Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6) I own a 2006 Lexus is 350. I have had two incidents of "unattended acceleration" but was fortunate that both occurred on the freeway and I was able to get the vehicle to stop accelerating. My question is this; I received a notice from Lexus, about six months ago, that there was a problem with the vehicle; however they were going to let me know when they had a fix for the problem. I've called several times, the last time was this week 3-9-10, and was told again that they do not have a fix and I need to wait and they would let me know when to bring the vehicle in. This seems dangerous, and I would like to complain that Lexus is not doing enough to either get me a replacement vehicle to drive until they fix the car, or fix it. [xxx]
