2017 Ford C-Max Problems

Car accelerated by itself in Drive. I'd to either apply brake or put the car in Neutral to stop it. When shifted back to D, it auto accelerated. After I got home, shut it off and after 10 min. it started working normally.

THE CAR WAS IN ACCELERATION MODE AT EVERY SPEED ON THE HIGHWAY, RESIDENTIAL STREETS, AT STOP SIGNS, ALWAYS EXCEEDING THE SPEED LIMITS. I CONTINUALLY BRAKED TO MAINTAIN CONTROL. TIRES SQUEALED WHEN I RELEASED THE BRAKE AT STOP SIGNS. THERE WAS NOTHING UNDER THE GAS PEDAL. I DIDN'T DARE DRIVE INTO THE GARAGE; THE CAR WOULD HAVE BEEN IN THE KITCHEN. WHEN I PUT IT IN PARK, ENGINE STILL REVVED.

Swollen lugnuts

Ford Dealer Service recommends I replace lug nuts. I have 35th miles. That they are expanding and Ford cannot assure they or other repair shops will be able to remove lug nuts for repairs or replacements such as brakes, tires, etc. I read many complaints online about this problem, that the lug nut can break causing other lug nuts to break under pressure, that cause tire to fall off. They do not replace under warranty and do not discount parts. I call upon NHTSA to have Ford recall these affected cars for replacement lug nuts. Thank you

Rear back-up camera does not display on dashboard console screen when air temperature is cold, i.e. below about 45º, and will only turn back on when the car has sufficiently warmed up after driving some distance. This has been happening for at least two years. When the camera is not working, there is a blind spot directly behind the car. The rear of the car proximity warning signal still works, but the screen remains black. I brought this problem to the attention of the dealership service manager, who told me he could not find anything obviously wrong.
