The truck unexpectedly downshifts to 1st gear when traveling up to 45 mph and causes a dangerous change in speed. It recovers after a few seconds and goes back to normal shifting. This has happened multiple times. Once about 6 months ago and then again a couple days ago.

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 cost of $8,300 for a total transmission rebuild.

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 part for the drive shaft recall. They have no time line for when they will be able to get the part and told me I may come get my vehicle and use it while I wait for the part but I have to sign a waiver stating that it's dangerous to drive. They refuse to give me a loaner vehicle if I would opt to leave my vehicle there while we wait for the part. I'm currently trapped in Texas with 2 horses and can't get back home to Pennsylvania because my vehicle is unsafe to haul the horses back 26 hours.
