Steering wheel became loose. Within a week I took it into a Ford dealer who confirmed this was a serious safety concern. They worked on the problem a day later. Steering wheel bolt was damaged and would not retain torque. The steering wheel bolt was replaced by dealer.

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.

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.

Dec 22, 2022Fuel systemSpeed control

The vehicle accelerate on its own accord, despite no foot or pressure to the accelerator, even going uphill and including after braking. For example, ona flat road, I stepped on the brakes and began to decelerate, I released the brake and the vehicle immediately began to accelerate forward at a high speed. I had to slam the brakes to prevent further movement. This is one of many instances, the most common of which is acceleration upwards of 10-15mph after the accelerator is released. It appears as if the accelerator remains pressed forward, I can feel the accelerator move back into place significantly later than when I remove my foot. I fear for my life and safety, and that of others. The vehicle is available upon request. I have not gone to a dealer or service center. The vehicle has not been inspected, but I have read similar reports online. There were no warning lamps or messages, but the issues began October 2022, and have increased in frequency since.

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

I own a 2017 Ford C-Max and share it with my husband. It is our only car so the past few weeks have been tough. Since I received my recall (22S43) in the mail, my car has been struggling to start. I believe this is due to the recall as the car is not in the correct gear to start the engine (even though I’ve been putting it in park & engaging the emergency parking brake). Yesterday, on our way home from the grocery store, our car gave us the “stop safely now” display; luckily we were close to home but it was still pretty scary. The engine had shut off. Also, I missed a doctors appointment last week because my car wouldn’t start. I almost missed my appointment for the RMV as well. Not only that but I had to cancel my trip to Lake George because the car feels unsafe to drive. I did not get a refund so the financial burden Ford is causing me for their negligence is frustrating to say the least. I bought the car a year and a half ago (Jan 2021). I have called Ford in Beverly, Framingham, Westborough, and Marlborough. None of the service departments could help me. They said that they won’t have the parts until the 4th quarter of this year. I’m not sure what to do at this point but would appreciate your help. My VIN is [XXX]. I am currently only using the car for “necessary” trips, though half of the time the car won’t start. Thanks, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2017 Ford Cmax Energi verdict →
