Lose Power Steering Problems of Ford C-max

Turned the car on in a parking lot and saw the check engine light was on. Had totally lost power steering and acceleration, and braking was extremely difficult. Rolled down the parking lot and was able to stop the car with the parking brake and turn it off. Turned it back on and the power steering and brakes and accelerator were back. Drove the car home and tried turning it on and off a few more times. Power steering seems to be completely gone. Check engine light is on.

I was driving to work one night down a residential street and suddenly lost power steering. The wrench light came on and a message displayed about the power steering. Luckily I wasn't on a busy street so I coasted to the side of the road and called a tow truck. When the tow truck arrived I turned the car back on and the power steering was working like nothing happened. The service light and message were no longer there. I still had the car towed to the Ford dealer and was told there is no problem with the power steering. That if it happens again try and get to a shop while the service light is on so they can see what code pops up. I was lucky that I was the only person traveling on that road and my rate of speed wasn't that high. If the problem would have happened on a highway or a busier intersection it could have been fatal.

Before 50,000 miles steering went from intermittently having no power to continuously having no power. Usually power steering is absent at start-up. Vehicle displays "service power steering" message. Obd2/can throws a pscm - power steering control module u3000 cm control module code. Steering would occasionally not work under warranty - asked at Ford if there were steering recalls and told there were none. I did not escalate because turning off the car one or more times would reset. Now that the car is outside of warranty, no action I can take, (such as restarting the car or clearing the error code) will reset the steering. Steering effort is much higher than any non-power steering car or old truck I have ever driven. The failed pscm (power steering control module) does not appear to exist as a stand-alone part. Ford tells me ~$700-$800 if steering column, or $2300 if rack and pinion need replaced. Hours spent searching for the part to do my own repairs has not given me a single part number that relates to the specific problem. This all seems to be part of Fords trouble prone and hugely expensive epas (electronic power assisted steering) system. Epas has had recalls in more popular Ford models, such as recall 15s18 beginning July 20, 2015. I suspect low production quantity cars such as the hybrid C-max likely have a similar failure rate, but it isn't noticeable due to the much lower quantity produced. Ford refuses to acknowledge the same flawed system on multiple models deserves the same fix. While I never lost power steering while driving, it would be catastrophic for small/weak drivers or those wha have never driven a vehicle without power steering. I've driven both cars without power steering and with failed power steering, but I have never had to use the level of effort it takes to steer the epas system whene it shuts down.

1st incident the vehicle completely died while I was doing 50mph down a 5 lane road. All electrical went out while I was driving. Lost my power steering and braking was extremely difficult. Had to have the vehicle towed as it would not re-start. 2nd time about two weeks after getting the car "fixed" the vehicle died while I was driving on i75 with same scenario. I was able to pull over on shoulder and had to have the vehicle towed in. 3rd time after getting the "fixed" vehicle back the radio went out, then the clock went wacky, the check engine light came on and when off. Then while running errands the car simply did not restart. No power to the dash, locks, etc. Had to have it towed in. Took the vehicle back again and the 4th time after driving an 1 1/2 hours to work the vehicle would not restart without being jump started. I had it towed to the dealer again and they cannot find anything wrong with it and I am being forced to take back a brand new 2014 Ford cmax energi with 4400 miles on it that keeps dying every week. I do not feel safe nor do I want the vehicle any longer. Ford has not yet sent any special assistance to the dealer to help rectify the problem.
