2021 FORD F-250 SD- Whitewright, TX
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

2021 FORD F-250 SD- Royse City, TX
This vehicle is subject to two open safety recalls for which no repair remedy is currently available from the manufacturer: 1. Recall 24V957 (24S78) Dec 20, 2024 involves the high-pressure fuel pump and powertrain control system. The recall states the fuel pump may fail and cause extended cranking/no start or loss of motive power while driving. Loss of motive power while in traffic or while towing increases the risk of a crash. The manufacturer has stated that parts and/or software are not available to repair this defect. The vehicle is regularly used for towing a recreational trailer, which increases the safety risk if loss of power occurs during operation, especially at highway speeds or while merging. 2. Recall 25V686 (25SA8) Oct 10, 2025 involves the 360-degree/rear-view camera system. The recall states that the rear camera image may become dark in certain reversing situations when front and side cameras are exposed to significantly more light than the rear camera. Reduced visibility while reversing increases crash risk, particularly when maneuvering a large pickup truck. The manufacturer has acknowledged both recalls but has not provided a repair remedy within a reasonable timeframe. The powertrain-related recall has remained unresolved for an extended period. The vehicle has not been repaired because the manufacturer states parts/software are unavailable. At this time, the defect conditions have not resulted in a confirmed failure event, but the vehicle continues to be operated with open safety recalls that cannot be remedied. The safety risk remains present due to lack of available repair. Due to the prolonged unavailability of a repair remedy for a recall involving potential loss of motive power, I am unable to safely use the vehicle for its intended purpose of towing, as doing so would increase the risk of a crash if the defect occurs.

I was driving on I-77 WV Turnpike when suddenly my moon roof shattered. No other vehicles were around and no overpasses in sight. When I pulled over, the glass was raised as if the blowout came from inside the vehicle. It sounded like a gunshot went off inside my truck. Vehicle has been repaired. Replacement glass was $1,800.00
