The car started accelerating on its own to 80 miles per hour in a 35 mph zone. There was a high risk of striking pedestrians. Immediately put the car in neutral and slammed the brakes and also engaged the parking brake. It was a very scary experience. Took the car to the dealer and the dealer was able to replicate the problem in the parking lot. Got the car throttle body replaced for $376. Apparently the throttle body sticks. Did some research on the internet and found that NHTSA has been investigating this issue for a long time. Not sure why a recall has not been issued? this defect could result in people getting killed -- I feel that I have a responsibility to ensure that something is done so that others do not experience the same problem.
