2017 Ford Fusion: start-stop system problems

Filed Oct 20, 2026 · Engine · FL

While driving, the vehicle suddenly lost engine power (it shut off) and displayed "auto start stop shift to P, then restart engine". The vehicle has never done this before, and thank goodness my wife did not have the kids in the car at the time. She was able to pull over safely only because she was on a small road with light traffic, and not at highway speed. Clearly, this put not only our vehicle at risk, but others as the brakes and steering became very hard to use when the engine just shut off out of nowhere. Since it happened today, I have not taken it in to be inspected as of yet. Upon my wife getting the car restarted she came the few miles straight home, where I did test the battery and it read good at 12.57 volts with the engine and accessories off. So the Motorcraft battery is good and as such should not be a cause in this case. To say the least, we have now lost confidence in this vehicle as being a safe mode of transportation.

My brakes are grinding squealing/rattling and i have pads replaced, no rotor wear, not sure what’s wrong. I’ve brought my car in to be serviced 3+ times and have left with no fixed car and worse brakes. When i bring up issues with my car that are related to the recalls the car has, they tell me those recalls don’t apply to my car although im having the same problems. My brakes have progressively gotten worse/louder and the pressure on my pedals is not the same. I’m scared to drive my car and i have been trying to get it fixed for months. This is not the only problem im having, my gas tank “farts” constantly and my car will stall and shut off unless i turn off auto start stop. There is no recall on this yet it’s a KNOWN problem. It makes the car undriveable.

Vehicle started making noises from the gas cap like vacuum noises. After refueling, car seem like it was having problems starting. After letting it sit for a couple minutes at the gas station, the car cranked but started putting like it wanted to turn off. Got to a red light and car suddenly turned off. Message shown on dash : Auto StartStop disabled. Manual Start Required. Car still wouldn’t crank. Got a scanner hooked up to the car and it said Evap Purge Solenoid Valve. There were recalls on this type of problem but not the same engine size. This could have caused a fatal accident had traffic been moving.
