I have a 2016 Ford C-Max. On Saturday, 9-16-2023 my wife and I were traveling on Highway 69 in Prescott AZ. We turned off the highway and about 50 yards from Hwy 69 a STOP SAFELY NOW flashed on the instrument pannel. The car IMMEDIATELY braked hard and stopped. I had no time to pull over. Had it been 50 yards sooner I would have abruptly stopped on Hwy 69. The Hwy was traveling at 55 MPH. You figure it out, we were going to have an accident 100%. The C-Max was towed to Sun Valley Tire, a AAA approved repair shop in Prescott Valley. They pulled up the Ford, Technical Service Bulletin - TSB 17-0015. That bulletin describes wiring that chafes and shorts out the car. Exactly what happened to us. The actual fix is simple, locate the shorted out wire and repair it. To get to it requires disassembling most of the car. Total cost $438.01. That is not the point, Ford knew that this problem existed, sent out a TSB and is allowing Ford owners like me to have a life threatening incident. WHY has Ford been allowed to continue allow these C-Max's to stay on the road without a fix! Are you doing your jobs? I want the federal safety agency to do its job. I also want to be reimbursed. Who do I contact. You have my VIN # and therefore all my information.

Several times now the vehicle has completely shut off while driving. At first, it was driving uphill on the freeway and when it hit a small bump it would shut off. I figured it was just at high speeds that this occurred. Recently, it was just driving up a driveway incline at 5 MPH, and going over a small speed bump triggered it to shut off. I have taken the vehicle in to have service fix it and they can't duplicate the issue. It is very dangerous to be driving 65mph on the freeway and the car just shuts off. It does not go into a safe mode, just completely shuts down. In order to continue driving, you must press the push-button start and let the car sit for a few minutes. After you wait, push the button again and it will allow you to continue driving as normal. I believe it is a wiring issue but multiple service locations have not been able to locate it. I have paid hundreds in labor attempting to fix it. Very dangerous!

Driving along a highway holding steady speed of 65mph, the car displayed a "stop safely now" message and disabled the accelerator. We were able to coast to a stop on the side of the road. The car would turn on and off with the push of the on/off button, but the "stop safely now" message remained on the dashboard any time the car was powered on, and the car would not move. We called ford as we are still under warranty; however, a tow truck would have taken approx 90 minutes, and I was not in a safe position, so I used a obdii scanner and app to reset the fault codes. After that the vehicle resumed normal operation. This is the third time we have seen this error in the last 18 months; however, the last time was approximately a year ago.

I was going to back into my driveway. I put the car in reverse then all of the electrical went haywire.everything turned on( windshield wipers, radio, all the lights. Etc.) then I put my foot on the gas to go in reverse and it went forward. Then I tried turning the car off and it would not turn off, so I was stuck in the middle of the street. I then moved the stick shift back and forth, put it in reverse again and it went a couple of feet, then wouldn't move anymore. All the electrical components remained on, but I couldn't turn the car off. I then had it towed to the car dealership with all the electrical components still on.they couldn't get it turned off either. They have it there and have no idea what to do. Now they can't get it turned on because the battery died.
