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.

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]
