“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. …”
