The vehicle was repaired. There were no injuries and a police report was not filed. The manufacturer was not notified of the failure. The failure mileage was approximately 300.”
NHTSA complaint #10986373, filed 2017-05, 300 miles“When running on a highway and you press down on the accelerator hard to merge onto a highway or go around a vehicle to move out of the way of vehicles quickly coming up behind you, the engine takes over and speeds up on its own. It has occurred three times on a newly purchased used car and it will increase speed up to 100mph. You have to press intermittently on the brakes to pull over to the shoulder and turn off the car for five minutes for the car to reset. If you try to just break, you get a burning smell. …”
