Power Train Problems of Lexus GX470

Unintended acceleration of a 2006 Lexus Gx470 when shifting from park to drive. This is the first known occurrence of this abnormal activity in the 6 months I have owned this vehicle. The engine rpms went from idle to wide open throttle for 2-3 seconds when I shifted the transmission into drive. Since my foot was on the brake I was able to keep the vehicle under control. The engine returned to normal idle on its own. Fortunately, I was in the middle of an empty parking lot and there were no damages and no injuries. The dealer (woodfield Lexus, schaumburg illinois) found no faults or failures upon initial inspection of the vehicle. Toyota motor sales, north America is sending me instructions on what steps I should take to address this dangerous and unsafe issue. I was told these instructions should arrive in the mail within 7-10 days.

When I purchased my vehicle from the Lexus dealer it had an occasional thump, bump clunk when I was stopped at stop lights. Sort like someone was trying to bump me forward. I have complained about this at every service appointment including warranty appointments. No one seems to know what it is. It has gotten much worse. I therefore have tried to do some internet research and appears that not only does Lexus know what it is but they might have actually published a technical service bulletin on the problem. I am fearful that the vehicle is becoming unsafe and I believe with the number of complaints I found on the Lexus sites that this is should be a recall issue not an issue that my dealer continually ignores. My Lexus also in cold weather (low 30s) has a large growling noise when stopped and brakes applied. I think it is part of the aforementioned issue. I have had my vehicle aligned a few times. It has a sensation of pulling right. However it stays true, pretty much, on the road. I should not have this feeling in the steering play. Lastly, I am constantly changing out the outside lights on the vehicle. Headlights, turn indicators and rear brake lights.
