Bought truck brand new. The axle bolt sheered off at 76k miles which is a common problem which Ford has issued a service bulletin for repair. Ford claims my truck is not drivable due to the manufacture defect of the bolt either being cross threaded or overtightened from the factory. Ford is insisting I pay for the mistake even though it's a manufacture defect with a service bulletin for a repair. Ford is refusing to pay for the fix due to miles. Axles, axle shafts and axle bolts should not have to be replaced before the differential fluid does in the axle at 100k miles. They are claiming the extreme premature wear is my fault. The truck is bone stock. Ford case #cas-43720120-d7h6y6. Worst part is Ford dealership telling me claim was denied to only find out Ford approved the claim partially. The Ford dealership was trying to double dip on profits. Dealership is wade Ford. Called up akins Ford in winder and they told me they would cover it.
For months have been having two issues with my 2021 f150 powerboost with the co2 sensors as well as an issue with the exhaust heat exchanger bypass valve a. Which after my bumper to bumper warranty expired now needs replaced even though the same issues have been throwing a cel for months.

I have owned my 2021 f150 less than 2 weeks. I purchased the car with 200 mile on it. I was pulling out of a parking lot tonight and heard a clunk. 50 feet later the engine quit and there was a strong fuel smell and something was scraping on the pavement. We got out of the car and there was a big puddle of fuel under the vehicle. Upon further inspection, the front fuel tank bracket was unhooked from the right side and the front of the fuel tank was resting on the pavement. The fuel tube connection at the front of the gas tank was sheared off. We had the truck towed to anderson Ford in rockford, IL.
I am filing this complaint regarding an unresolved safety recall on my 2021 Ford F-150 (VIN: [xxx] ), recall 25s75 / NHTSA 25v455, issued July 2025. As of today, April 10, 2026, no remedy is available and Ford has not provided a firm commitment beyond a verbal statement from a customer service representative. I contacted Ford in writing via certified mail (delivered March 27, 2026) and by email. Ford case number: [xxx]. I received one email response on March 31, 2026 from patrice hargrove, truck concern cxs, stating the remedy would not be available until June 2026, that Ford had not advised me to stop driving, and that Ford would not provide a loaner or rental reimbursement. I responded the same day asking for written confirmation of the June 2026 date and confirmation that my correspondence had been documented in my case file. I followed up again on April 6, 2026. I have received no response to either email. My concern is not only the recall itself but the history of this specific vehicle. In October 2022, this truck stalled in the middle of the street while I was driving with my children in the vehicle. It was towed and serviced, with the cause attributed to alternator failure. The failure mode described in recall 25s75, an engine stall caused by fuel pump failure, is the same experience I have already had with this truck. This vehicle has also undergone a rear axle wiring harness repair in June 2024 and a transmission service under customer satisfaction program 25l02 in December 2025. I have two young children who ride in this vehicle regularly. Ford has acknowledged a safety defect that can cause an engine stall while driving, has provided no interim safety accommodation, and has not responded to my follow-up correspondence in over a week. I am requesting that NHTSA review Ford's handling of this recall and the adequacy of Ford's response to affected owners. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
