    I own a 2020 Ford F-350 Super Duty (VIN: [XXX] , mileage: ~20,000). The vehicle is subject to a recall involving the transmission output planetary four assembly replacement. Ford and the dealer insist that the transmission must be disassembled and rebuilt to complete this recall. I do not agree with this solution because it permanently alters the integrity of the original transmission. Additionally, the dealer (Route 23 Auto Mall, Butler NJ) has repeatedly mishandled repairs, including installing the fuel filter incorrectly multiple times. I have opened several case numbers with Ford Customer Service: Recall Case No: [XXX](02/02/2024) Fuel filter dealer error: [XXX] (01/06/2025), [XXX] (01/15/2025), [XXX] (08/26/2025) Transmission recall follow-up: [XXX] (02/25/2025) Buyback case (denied): [XXX] (03/04/2025) Despite multiple cases, Ford refused to buy back the vehicle because it is registered under a company name. This is unfair and leaves me with a defective and unsafe vehicle. I request NHTSA to investigate this recall and require Ford to provide a new transmission replacement instead of a rebuild, and to review Ford’s handling of dealer errors and warranty obligations.

    I WAS DRIVING FORWARD APPROX 5 MPH AND LOST ALL CONTROL OF THE STEERING. THE STEERING WHEEL WAS NOT MOVING THE FRONT TIRES AT ALL. THERE WAS NO WARNING, AND INDICATION THAT THE STEERING WAS GOING BAD. THE TRUCK IS 2020 WITH APPROX 80,0000 MILES. NOT LIFTED, NO OFF ROADING. THE STEERING WHEEL WILL JUST SPIN NO STOP TO IT IN EITHER DIRECTION. MY UNDERSTANING WITH THIS TRUCK IS THERE IS NO INTERMIDATED SHAFT SO IT DIDNT SLOWLY GO OUT. THE NIGHT BEFORE MY FAMILY AND I WERE COMING DOWN FROM LAKE TAHOE WITH A BOAT ATTACHED. HAD THIS HAPPENED AT THAT SPPED WITH A TRAILER IT WOULD HAVE BEEN A VERY DIFFERENT OUTCOME.

    When exiting the interstate and coming to a complete stop at the bottom of the exit ramp we went to make a right turn onto a two lane mountain road when we felt a hesitation and within seconds the engine began to sputter, we lost power and the check engine light came on. This was a two lane 55MPH road with no shoulder pull off. Thankfully there was no oncoming traffic in the other lane and there was also an abandoned fruit stand parking lot which were were able to drift across the road and stop in. We experienced a COMPLETE loss of power. Had there been oncoming traffic or no open parking lot just across the road we might have experiened a crash. It is important to note that we were on a vacation in the mountains and thankfully our RV was parked at the Campground we were not towing it at this time. We had to find a tow service to have the vehicle towed to the nearest Ford Dealership in the area. The Dealership notified us that there were metal shavings/flakes in the lower fuel filter housing. They told us that this was a Complete Fuel System Failure and that we would need a complete fuel system replacement of all parts. We had been notified of the recall (Safety Recall Notice 24S78/NHTSA Recall 24V957) in January 2025 and we had taken it to the local Ford Dealership who advised there was no fix for the problem at this time. The Dealership that our truck was towed to after this incident advised us that we would have to pay for all the repair costs (excess of $10,000) as this was still an open recall. We feel that this is a MAJOR safety issue - we were due to leave for home the following morning where we would have been towing a 7500lbs travel trailer on the interstate roads. Had we experienced this failure then it could have been truley tragic for not only us but other motorists. After this incident we called Ford Motor Company and advised them and they told us it was still considered an open recall with no fix available.

    Passenger, right side door mirror has failed in that while driving, regardless of speed, the mirror no longer stays outright and provides rear and blind spot view capabilities, therefore making lane changes hazardous with a high potential for crash probability. The internal mechanism(s) have failed and while driving the side mirror folds inward and collapses towards the door making it impossible to see what is next to you in an adjacent lane as well as what may be approaching from the right rear and right lane. The vehicle is scheduled to be inspected by a Ford dealership tomorrow (8/1/2025) to be assessed and see if they will replace the mirror. The mirror in question is pristine and has not been subjected to harsh treatment or been struck by any outside forces that would cause internal damage. No crash reports are associated with this vehicle.

The dealer was notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was filed. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was unknown.

    The rear back up camera of my 2020 Ford F350 Superduty has not been working for several months, then in May of 2025, I found the recall notice about this issue and Ford has said that my vehicle isn't part of the rear back up camera recall, even though it has the same exact problem of the other vehicles involved in the recall. My vehicle was built in October of 2020 which falls into the same time frame of the other vehicle models and build dates. Will Ford be held accountable if I happen to back up and hit someone or damage something? My vehicle along with probably many other vehicles need to be added to this recall.
