I own a 2007 Avalon. We recently had a light snowfall of two inches. Upon turning into my dead-end street (a very slight decline),I heard a beep. After that, I had no control of the vehicle and it coasted down the street, past the left-hand turn I needed to make and came to rest on the road. Thankfully, this was a small dead-end street, I was going slowly prior to losing power (5-10 mph),and there were no other vehicles near me. If not, I easily could've caused an accident. After coasting to a stop, I tried to go in reverse (slight incline) to get back to the turn I needed to make. However, the accelerator was unresponsive when I tried to do so and the traction control light was on. After several attempts, I decided to go forward and make a U-turn in order to get back to the street in which I needed to turn. I was able to go forward and turn around but after doing so, again the accelerator was unresponsive (facing very slightly uphill now). After trying the accelerator several times, I shut the vehicle off and restarted it but the accelerator remained unresponsive. I then put the car in "drive 2" and was able to inch my way up slowly to the (now) right-hand turn I needed to take. Upon making the turn onto the level street, power returned to my vehicle and I was able to get to my house. After the incident, I took the vehicle into northway Toyota (place of purchase) and had them check it out. They said the traction control system was working as it should and that there was no way for me to shut it off. I also asked them to check the tire tread thinking that this may have led to the problem and that snow tires would possibly help the situation. The service dept. Told me that there was approximately 50% tread life left in the tires (the car has approximately 23,000 miles on it) and that the tires I had should be fine and snow tires wouldn't be helpful. This incident could obviously be very dangerous should it occur again. Please look into this and come up with a solution.
