“Pulling out of my garage my car accelerated out of control at high speed backwards across the street into the side of my neighbor's house taking her electrical box, sprinkler motor and A/C unit down. The wire's were hot and I was advised to stay in the car until the firefighters arrived and the power shut down by the power company - scared to death of a fire or electrocution.”

NHTSA complaint #10521182, filed 2013-06, 75,000 miles“First time problem happened was july 3, 2016 with my 2006 Kia Optima. I was sb on hwy i25 in cs, co. Speedometer read 25mph as I was coming off the on-ramp. I accelerated to 40mph into flow of traffic. I felt a lurch & the vehicle automatically accelerated. Speed went from 40mph to about 60 MPH without depressing accelerator. Breaking did not slow it down. I felt car was going out of control. My passenger reached over & turned ignition switch off & on quickly, to decelerate & accelerate. …”
NHTSA complaint #10905623, filed 2016-09, 103,083 miles“My Kia Optima accelerator sensor went out about a week ago. It would not go above 20 miles an hour. I turned the ignition off and restarted it. When I did that, it took off like a jack rabbit without even touching the gas pedal. Dealership towed it for repairs. They said it was dangerous to drive. It was determined to be the accelerator throttle sensor. The defect was repaired and no further incidents have occurred to date.”
NHTSA complaint #10365910, filed 2010-11, 79,000 miles“I went to go shopping, and at the second stop sign in my neighborhood I stopped. When I tried to drive the gas pedal when pushed would not let the engine go fast enough to go above 20 MPH, then I noticed that the check engine light was on. I pulled over and checked my engine and its fluids, could not find any thing wrong. So I started the car up again, and everything seemed to work fine. So I drove off and the car worked like it should have. I then went to a auto parts store, and they used their meter to check engine codes. …”
