Example complaints

“We picked up our new 2009 Avalon limited on 7/31/09. On 9/7/09, after returning from a drive, the car accelerated into the garage door as it was opening. We had stopped about 6 feet from the door to open it. As we released the brake pedal the car shot forward into the door. Damage to the car amounted to $1500, and another $1000 for the garage door. I did not file an insurance claim. Toyota later recalled the vehicle to put a spacer on the gas pedal and to re-flash the computer. I believe this is an electrical problem with the gas pedal control system and not a mechanical problem. …”
NHTSA complaint #10312990, filed 2010-02, 1,350 miles“The vehicle started making a subtle vibration both in motion and stationary noise. The next day the vibration noise was a little worse. Took to dealer. They said it was a transmission problem. I questioned at under 60000 miles, the shrugged. 6964.08 dollars later and 4 days, noise was gone.”
