| Car Accelerates On Its Own problems |
The contact owns a 2010 Volvo S80. The contact stated that while stopping at an intersection and trying to accelerate, the vehicle suddenly stalled and would not move. Once the vehicle was started, it suddenly stalled again halfway through the intersection; the engine revved but the vehicle would not move. The vehicle had not been inspected or repaired. The failure mileage was approximately 2,200.
Driving on city street at about 30-35 mph. As I approached intersection I took foot off accelerator pedal and stepped on brake pedal to slow down and stop at intersection. As I stepped on brake pedal, I could hear engine start accelerating and car wouldn't stop. I noticed tach reading between 4 and 5. Although engine was accelerating and vehicle was moving forward it was not moving at excessive speed. I pressed harder on brake pedal and while car slowed somewhat it would not stop. So I decided that the only way to stop vehicle was to move gear shift lever to park and then turn off engine. I then restarted car and it functioned normally. My experience might be an example of what has been called "sudden, unintended acceleration".
