Last year I experienced a mystifying auto problem. While stopping at a traffic light, my car accelerated suddenly without any action on my part. Imagine the frightening feeling of having your foot on the brake, when suddenly the car accelerates and jerks forward. It took a bit of investigation before baffled mechanics figured out the cause. The break pads and rotors needed replacing. A simple solution, yet one I failed to recognize at first thought. If you're baffled as to the cause of sudden acceleration, look to the brake pads and rotors. Replacing the worn out parts may be costly, but driver safety and peace of mind is well worth the investment.
