As I was driving I lost power steering and almost crashed the car. A red alert and sound on the dashboard told me “steering assist failure service vehicle”. Also the light on the dashboard for steering was illuminated. I was able to barely drive the car home (approx 3 miles). Took to my local mechanic and had the error code: u3000 49-08 Driving the car by my husband in our neighborhood resulted in the same problem including the warning sounds and message. He was able to restart the car and the steering was fine and was able to drive it back to its parking spot. Took the car to the Sheehy Ford dealer today and am being told it is a 3k repair to replace the rack and pinion.

The crank shaft position sensor has failed five times and required replacement. On two occasions when this sensor failed it resulted in total loss of power while the car was on the road and in traffic. This could have resulted in crashes and injury.

Vehicle is not holding EV now/later modes causing unexpected battery usage and fuel consumption. An example is traveling highway speeds (70-75 MPH); vehicle will unexpectedly switch into auto mode and revert from gas/hybrid performance to electric/battery only performance which is reduced power and response again at highway speeds. This is not always the case as I have found this to happen before I enter the highway and can adjust my drive accordingly. Additionally, this happens in EV now mode which holds the electric engine to prevent gas use at all but the system will inadvertently switch to the auto mode. Condition is extremely sporadic and difficult to replicate most times will happen without throwing a check engine light code. Fortunately I do have a few instances where a code was thrown and I was able to have the dealer take a look and make some warranty repairs none of which have resolved the issue as it still comes back in the same random form. Attached are the several dealer visits to address the concern and after several visits, the transmission pump module seems to be a repeat issue. Unfortunately not sure if this is the cause of the modes not holding as it should.

Driving my 2015 ford c-max and all of a sudden I lose power. I press the gas and nothing. I was driving through a intersection and had to coast to the side of the rode. Big red triangle show up saying "stop safely now". Car has been at the dealer for 4 days, they are trying to find the problem. I have read online about this problem with multiple ford vehicles and a recall was called for the focus. I guess ford is to big to go after and the ntsb drags there feet like no other. Call for a recall on all vehicles that "stop safely now'. Will you wait until people die to do something!!
