The back up camera and detection system glitches out when the weather is hot outside. When the cameras goes from working to not working or giving glitching screen effects it really affects the safety of being able to see what’s behind you while backing up.

There is a clearly a problem with the software that’s affecting my same year model.

We were on the interstate and our truck had reduced power and then failed. The diesel particulate filter light came on as well as the service engine soon warning. We were hauling our 40 foot 5th on the way home from a trip. We were able to make it to the side of the road but it would not start. It would crank for a while then quit. We were stuck on a very busy/dangerous highway for over 2 hours waiting on a tow truck to get us. It cost $500 to be towed to the ford dealership 2 miles away. We were nearly 3 hours from home. Our truck and 5th wheel are both still at the dealership. We were told today that the fuel pump exploded leading to shards of metal throughout the system and that it would be $15000-18000 to repair. There isn’t a solution with the recall but it will be covered under our powertrain warranty. We are left without a truck and have no way to get our camper home until it’s repaired.

The truck has developed a significant knock coming from the intake manifold. It is loud enough to hear with the hood closed. The problem exists warm and cold. The knock was verified by Sunrise Ford in Fontana, CA in December of 2024. The Dealership had another F250 on the lot with the same 6.2 engine and that it also has a knock coming from the intake manifold, so they considered the situation "normal". There is a significant amount of information available that the knock is related to an impending failure of the Intake Manifold Runner Control (IMRC). If the IRMC fails, the parts will go into the combustion area and could cause an immediate catastrophic failure of the engine. At best this problem creates a loss of power and a pulsing vibration at idle.

I am the original owner of this 2021 F250, (by my notes, dates & miles may differ slightly by Ford/Dealer records) I first noticed Death-Wobble around [XXX] @ 3,040 miles & Ron Alpen Ford checked factory alignment & ordered an updated steering stabilizer. Updated steering stabilizer was on back order until around 8/8/23 @ 26,647 miles when it was installed on the F250. As you can see, over two thirds of this truck's three year bumper to bumper warranty was dissolved by back order. This is where I believe Ford Motor Company's engineering group got involved & recommended a custom alignment, I believe this was performed by Ron Alpen Ford around 4/8/24 @ 33,486 miles. As you can see, over half of this truck's remaining warranty was dissolved waiting on Ford Motor Company's assistance. Ford Motor Company fell silent after recommending I take the truck to a different Ford Dealer for a second opinion... I still do not believe a second opinion was the correct opinion of Ford... Ford should have supported Ron Alpen Ford further in this repair. I set up an appointment at Courtesy Ford, Courtesy had the truck for two full weeks straight... Ford claimed that the truck had conveniently made it outside of the warranty period... 12/3/24 @ 35,922 Courtesy replaced the drag link & the steering stabilizer a SECOND time as the continuing death-wobble had destroyed the first updated steering dampener at my expense because the truck was conveniently out of the 3 year warranty period...

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.

On multiple occasions now I have experienced the death wobble after hitting a bump in the road. Today the vehicle shook so violently that it crossed into the lane next to me on a curve.
