“Transmission. When the temperature is 40 degrees or below I sometimes have an automatic transmission problem. In the morning after the vehicle was parked over night I start the vehicle, put it into reverse, I back 40 feet down my driveway which has about a 30 degree grade down to the street.. …”
NHTSA complaint #11174390, filed 2019-02, 60,000 miles“Part of my power in my car shut off on the freeway, at 1:39 pm at 67 degrees outside . I had been driving for 40 minutes. My dashboard went dark, and only my clock time was on. I glided to the side of the road, and was able to pull the car very hard to the right (as the power steering was off). Then turned the key to off, waited 3 minutes turned the key and it went back on. It has not happened again.”
NHTSA complaint #11093939, filed 2018-05, 112,000 miles“Driving car, stopped at traffic light, or leaving places the transmission will not engage when put into drive. It gets stuck and won't move. This is very dangerous as I have almost been hit from behind when this happens. I have to put in park and try again and it sometimes shifts or makes a loud cluck and jerk. Happens off and on. Took into the Ford dealer couple of times and they said they could only determine what the problem is if it does it with them. Never does it when in the shop. …”
NHTSA complaint #11182232, filed 2019-02, 89,000 miles“Driving stopped at a stop sign noticed the wrench light on (happens often while this happens will not accelerate like normal until it hits 2-3rd gear). I press the gas to accelerate after making the turn I had to make another turn about 1/4 mile up the street. I released the gas to make the turn but my car kept accelerating it was not going very fast but the engine was accelerating pushing the rpms up to 6000. My foot was not on the gas and nothing was pressing the gas no floor mat or items in the way of the pedals. …”
NHTSA complaint #10574690, filed 2014-03, 100,200 miles“1) driving at steady speed. 2) let up on gas pedal and car did not slow down. Occurred twice in three times that vehicle was borrowed from a friend; one time with a witness. 3) pulled my foot completely off floor and applied brake; problem (in my opinion) is poor pedal orientation which leads one to believe that gas pedal is no longer pushed when one just lets up on pressure on gas pedal, along with too lite of pedal return pressure. Have been told Ford is aware of this but feels it only happens if someone is wearing big and heavy work boots. …”
