2021 Ford F-250 SD engine problems

Filed Nov 4, 2026 · Engine · AZ

I have a 2021 Ford F250, the truck was bought new has 34,467 miles on .Oil changes every 5000 miles. Was returning home from camping and engine developed a miss, engine light came on,I was able to make it home and engine developed a loud ticking noise in the upper part of the engine. Truck was towed to a Ford dealer ,where it sits for the past 2 weeks ,waiting on Ford to decide what they are going to do with it. Dealer told me ,after a tear down ,that Ford wanted ,that it was the cam and lifters. This is a known problem ,and Ford dropped the ball on a recall on this engine. Besides the cam ,lifter issue ,there is an oil pump problem with this year engine. I bought the truck as a retirement gift to myself, and now appears to be the worse decision I've made. I believe Ford needs to replace the engine and not just fix the cam and lifters as small metal particles will be through out the engine due to the above failures and will cause a failure again.

I took a functional vehicle to Swant Graber Ford in Barron, WI in on [XXX] for Recall 24S78 and since then I have had numerous vehicle issues involving the PCM that they flashed. I have up to 16 different codes when the check engine light comes on including numerous communication U-codes indicating faulty software download causing no run/no start problems along with severe safety concerns while driving. I returned the vehicle to Swant Graber today July 1, 2026 after 2 weeks being this was their earliest appointment availability. They then deleted the codes and told me to drive it until there is more issues which is a severe safety concern considering the condition of the PCM of this vehicle they returned to now which is unfunctional and not road worthy INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2021 f250 with the 7.3v8. 120000 miles and lifter has failed. We believe that we caught it early enough to where we have no more issues other than this. After reading up I have noticed where there has been several other customers with same issue on this engine. I run several f350 pickups with our business and have been very pleased and bought this pickup to run around in and keep from driving the work trucks. I would like to think that this should not be an issue with this amount of miles. I hope ford steps up and fixes this issue

The vehicle experienced a sudden loss of motive power and became inoperable due to failure of the high-pressure fuel system. This VIN is subject to an active safety recall (the federal safety agency 24V957 / Ford 24S78) addressing high-pressure fuel pump failure that can result in loss of motive power while driving. Prior to failure, the vehicle exhibited reduced engine performance and drivability issues consistent with fuel system malfunction. No Water-In-Fuel warning or alert was displayed prior to the failure. The vehicle was inspected by an authorized Ford dealership. Ford and the dealership asserted “fuel contamination” as the cause and refused to repair the vehicle under the recall or warranty unless the customer paid for diagnostic teardown. The recall repair was not performed. The vehicle remains unrepaired and was removed from the dealership. The loss of motive power created a safety risk to the occupants and other motorists. We are concerned that a recalled safety defect affecting the fuel system is not being remedied and is being mischaracterized to avoid recall repair.

ON YOUR VEHICLE, IT MAY BE POSSIBLE FOR AGED BIODIESEL DEPOSITS TO ACCUMULATE IN THE HIGH PRESSURE FUEL PUMP. THIS MAY RESULT IN EXTENDED CRANKING WITHOUT STARTING WHILE THE VEHICLE IS PARKED, OR LOSS OF MOTIVE POWER WHILE DRIVING. My vehicle has been inoperative for MONTHS due to this recall, per the manufacturer. We had no warning lights or problems prior to trying to start the vehicle and that failing. We took it to the manufacturer, and they said it was because of the recall. The recall date is Dec 20,2024 and it is now June 24, 2025. That is 6 months without a remedy. This is not being taken care of in a timely manner.
