2017 FORD F-350 SD Power Train Problems

While driving my 2017 Ford F-350 equipped with the 6R140 transmission, the vehicle experienced a sudden and complete transmission failure due to a valve body malfunction. Without warning, the transmission lost all ability to engage gears, resulting in an immediate loss of power and drivability. This failure occurred while the vehicle was in motion, presenting a serious safety risk to both occupants and other motorists — especially in high-speed or high-traffic situations. The risk is further compounded when the vehicle is towing, as it may increase stopping distance, reduce control, and leave the driver stranded in unsafe conditions. This type of failure appears to be part of a broader pattern affecting this transmission platform, which raises significant concerns about its reliability and safe operation under normal usage. There were warning lights or other symptoms prior to the failure. The damage has since been remedied, with an astounding out of pocket...

The owners manual states I have a tank capacity of 36 gallons. On E I can only fit about 26 gallons. If I were to take my average MPG and use the advertised 36 gallons to figure out how far I would run out of fuel and this would cause the vehicle to stall while driving. Ford is aware of this issue and knows how to fix it but declined to take care of the safety repair.

2017 Ford F350 Superduty 6.7L diesel will intermittently surge/buck while towing uphill under load causing loss of power and creating unsafe driving situation. When it happens I’ve also observed electrical power loss to OBD-II port where I have accessory guage installed to monitor critical truck systems like oil temp, trans temp, coolant temp, etc.. No DTC or fault codes are generated when this happens. I haven’t taken to dealer yet but I’ve researched and read lots of truck forums where multiple Ford owners have had the same issue. When they’ve taken their truck to the dealer they’ve been told this is “normal”. I don’t agree and believe this is a serious safety issue to a consumer that suddenly loses all power and must let off all acceleration while other cars are following/around vehicle when vehicle surges. This has now happened four different times and various speeds (30-60 mph).

Truck started doing the death wobble when hitting brakes and sometimes when hitting bumps in the road. Death wobble was very violent and last for a few seconds each time before we could get vehicle stopped. I made my local ford dealer aware of my problem and they inspected it and said it was related to the drive shaft recall. I made the earliesr appointment which was a couple weeks later. I dropped my vehicle off and they said that due to this recall malfunction it had caused damage to my tie rods and drag lengths and those parts needed to be replaced. They said their damage was directly correlated to the drive shaft recall however I would have to pay out of pocket for that to be fixed ($1400). They have had my vehicle for a week and fixed the tire rods and drag lengths but do not have...

THE CONTACT STATED THAT THE DRIVER PARKED THE VEHICLE WITH THE ENGINE IDLING, THE DRIVER EXITED THE VEHICLE AND 10 MINUTES LATER, THE TRANSMISSION ERRONEOUSLY SWITCHED TO THE REVERSE POSITION CAUSING THE VEHICLE TO ROLL AWAY AND CRASH INTO A PARKED VEHICLE. THERE WAS NO ONE IN THE VEHICLE DURING THE ROLL AWAY. NO INJURIES WERE REPORTED AND NO POLICE REPORT WAS TAKEN. THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE LOCAL DEALER VARSITY FORD (3480 JACKSON RD, ANN ARBOR MI. 48103) WAS NOTIFIED OF THE FAILURE. THE MANUFACTURER WAS NOT NOTIFIED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 60,000.

EXPERIENCED HEAVY OSCULATION AT 25K MILES. AT 26K MILES THE TRUCK WILL GO INTO A "DEATH WOBBLE" AT SPEEDS OVER 60 MPH. ANY TIME I HIT A BUMP IN THE ROAD AT SPEEDS ABOUT 60 MPH THE TRUCK VIOLENTLY SHAKES AND IT'S VERY DIFFICULT TO MAINTAIN CONTROL OF THE VEHICLE. THIS IS A HUGE SAFETY CONCERN. TOOK THE TRUCK IN TO GET IT REPAIRED UNDER THE WARRANTY. THE DEALERSHIP WAS VERY FAMILIAR WITH THE DEATH WOBBLE. THE TRACK BAR WAS ON BACKORDER; HOWEVER, I FOUND ONE AVAILABLE AT ANOTHER DEALERSHIP. I DROVE THERE, PICKED IT UP AND TOOK IT TO THERE DEALERSHIP WHO FIXED THE TRUCK THE FIRST. GOT THE TRUCK BACK SEVERAL DAYS LATER. AT 31/32K MILES, IT STARTED TO DO THE OSCULATION/VIBRATION AND STEERING WHEEL SHAKE WHEN I HIT ANY BUMP ON THE ROAD/ROUGH PATCH AT SPEEDS OVER 60 MPH. TOOK THE TRUCK BACK TO THE SHOP AT...
