The transmission suffers erratic shifting normally between 3rd to 5th, and 9th to 10th gears where it feels as if the transmission goes into neutral when upshifting or downshifting between these gears. But, one issue occurred which has concerned me. After stopping at an intersection, when it was safe to proceed, I moved my foot from the brake to the gas pedal to proceed. The engine revved to higher RPM's, but the truck did not move as if it was in neutral instead of gear. As I looked down at the tachometer, the truck suddenly locked into gear causing the tires to chirp and the truck then lunged forward through the intersection. This was a T intersection where you have to turn right or left. This incident was so harsh and unexpected, it threw me back into my seat. I was able to maintain control and make my turn to the left without going off the end of the road. This incident has not happened again, but the erratic shifting continues.

My truck currently has 92,305 miles and are all highway miles. This truck is not used for towing outside of the weight rating. The issue is that there was a vibration when I reached speeds of 65mph and higher. The dealer states that the rear end has excessive back lash, excessive wear in the ring and pinion gears and metal shavings in the rear differential fluid. Ford's rear differential service recommendation is 100,000 miles which I have not reached. I'm now required to pay over $3200 in repairs for the carrier bearings, hub bearings, pinion bearings, seals and rings plus the transmission fluid. Based on my driving habits, I do not think this issue is something that I caused, I believe it to be a Ford issue which they deny. I have read many blogs online where other owners have this same issue and someone needs to look into it further.

Known mechanical design issue with the 10R140 transmission CDF drum where a bushing moves blocking / partially blocking fluid transfer ports. This causes transmission fluid overheating, clutch slippage, hard shifting, etc. This mechanical design issue poses a danger to the driver, passengers and other surrounding vehicles when this potential failure occurs.

I bought this truck used with 20K miles on it, after only two days of driving it. I was in the credit union parking lot, started it up, foot on the brake, put the truck in drive and it Leaped Forward. I had to jump harder on the break to stop the motion. I almost hit the truck crossing in front of me. If he was heading the other direction and closer to me, I would have easily hit him. This morning 28 Oct 2022, I stopped at the gas station and filled up and the same thing happened when leaving the station, but no one else was around.

The forward heat shield/sound insulator became dislodged from the retainers and dropped onto the forward driveshaft. This damaged the driveshaft. This incident could have resulted in the driveshaft fracturing and may have resulted in an accident. This condition is documented in NHTSA Campaign number 22V-087 and Ford recall 22S09. Per the Ford dealer who repaired the truck and per an employee of Ford Motor Company, the two wheel drive Ford Super Duty trucks have not been included in the recall. These places thousands of vehicle owners at risk of an accident related to this condition.

Dear staff; I purchased my 2021 Ford F-250 new July 25th, 2021. I noticed my undercarriage was covered in great portions of rust. The front driveshaft to the outer ends and the rear housing, including the rear driveshaft u-joint has a significant amount of rust. What-??s surprising is I have only 5400 miles and the truck appears to look 20 years old. I have a neighbor who is a GM of another competitor dealership. He crawled under the truck and said this is a safety issue which needs to be addressed. Two Ford dealership Service managers informed over the phone this is a common issue and not to be concerned. I have owned eight Ford pickups throughout my life and never had this deep concern. Knowing this rust has perforated the tie rods, I don-??t feel safe driving this $60,000 vehicle. My only recourse since Ford won-??t honor its warranty is for me to trade it in on a GMC. I have been loyal to Ford for 36 years to finally get shrugged off.

The 10-Speed Automatic Transmission shifts hard and randomly. Leaving a stop sign, at any rate of speed, causes slippage in the shifting. Sometimes it'll shift too slowly, resulting in a jerky motion of the vehicle. Sometimes when on the highway, usually traveling at 68mph (cruise control), the vehicle will randomly jump gears when it's not necessary. Recently while getting up to speed we heard a large grinding noise shifting into 4th gear. The vehicle, otherwise, runs great. The transmission leaves alot to be desired and I do not have any confidence in the shifting. It's comparable to a teenager just learning how to drive a stick shift. If I wanted that, I would have one. My transmission fluid is where it should be and the vehicle has less than 8,000 miles on it.
