Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers.

Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I recently bought this truck used from a Ford dealership. The next day when I was taking my wife for a short drive. I noticed the engine light was on the dash display. I the same time the truck started accelerating Like it was on cruise control and returning to a higher speed. The cruse control was not set when I tried to access the cruse control I would get the message that it was unavailable at this time. I had to stop the truck and turn the truck off. When I restarted the engine light was still on, but the acceleration stopped. I drove to the dealership to see if they had any information or recalls but by the time, I got there the engine light was off and their computer did not tell them anything. This has now happened two times. The dealership says I must bring the Truck in while this is happening. for them to get a reading. This is not my primary vehicle, and I don't drive it all the time and it is 45 minutes from any dealership. The uncontrolled acieration is a safety issue. The problem has not been reproduced Dealer thay had no idea what was happening. The warning lamp engine and the cruse control not available message., I am wondering if anyone else has had the problem?
