“Occasionally while stopped at red light, my engine will rev unexpectedly without my me touching the gas pedal, this has caused my car to jerk forward on several occasions and has almost made me hit the car in front of me and worst it has forced me into the middle of intersections.”
NHTSA complaint #10318187, filed 2010-03, 140,000 miles“As I was driving down the highway I accelerated to pass and it seemed as if my throttle shorted out. My car's RPM's dropped and I started to decrease speed. I removed my foot from the accelerator and it seemed to catch again, but as I pushed the pedal again my accelerator went out for a second time. At this point and my engine shut down. I shifted into neutral and tried to restart my car multiple times while rolling with no success. …”
NHTSA complaint #10357146, filed 2010-09, 102,000 miles“I was on my way to work when the vehicle in front of me came to a complete stop. I was approx. Three car lengths behind her (which is plenty of distance at 25mph) when I applied my brakes though nothing happened. They made a grinding noise (like the pads were gone, but they are new ceramic pads). I ended up hitting the vehicle in front of me. I got a citation for following to close, which is $260.00, my insurance was increased by over $100.00 a month, I had to pay for her car plus $3750.00 of damage on mine. …”
