2021 FORD F-250 SD Complaints

All of my rear lights stopped working with no warning. My blind spot monitoring and cross traffic detection also stopped working. This is a serious issue as the light go out intermittenly without warning. Especially dangerous at night. Dealership thinks it might be a faulty harness. Dealership thought they fixed it by cleaning contacts but the very next day they went out again while driving in a snow storm. Luckily no one was behind me because they would not have been able to see me.

Both the driver and passenger mirrors will not fully adjust. The mirrors need a different adjustment for standard driving and when towing a travel trailer. Neither mirror will properly adjust for towing and non towing applications. The lack of proper mirror adjustment causes a safety issue as the driver cannot see things in their full scope due to the mirror misalignment. I have almost had two accidents due to the mirrors not being able to be properly adjusted. Ford is aware of this issue on 2017 to 2023 F150, F250 and F350 trucks with the tow mirrors. Ford has issued a Special Service Message#51829. Ford has a cleaning procedure they wish to be done as part of the diagnostics but Ford and the Ford Dealer will not release this information. Ford is attempting to block warranty claims related to this issue. I believe they are doing this so they will not have to issue yet another recall! I spoke with a Ford Dealer this morning and they stated that they had no knowledge of the SSM51829 or the mirror cleaning procedure. Even though the truck is under the Ford warranty, they would require a $250.00 dollar fee just to inspect the problem.

My 2021 Ford F-250 equipped with the 10R140 10-speed transmission suffered a sudden internal failure around ~100,000 miles. The failure symptoms and internal damage match the defect Ford acknowledged in Safety Recall 22V-256, which applies to the 2020 F-250/F-350 trucks using the same 10R140 transmission. Despite identical symptoms and the same transmission design, my VIN [XXX] ) was excluded from the recall. NHTSA’s VIN decoder also returned an “ambiguous model year” notice, suggesting this vehicle may have been built during the transition period where Ford continued using the same defective 10R140 components. Symptoms experienced prior to failure included harsh shifting, delayed engagement, gear slipping, and eventual loss of drive. A transmission shop stated they “won’t touch these transmissions” due to known issues. The failure created a serious safety risk due to sudden loss of power while driving. This appears to be a recall scope error. Early 2021 units like mine are experiencing the same 10R140 internal failures as the recalled 2020 population. I request NHTSA investigate whether Ford under-reported the affected VIN range and whether the recall should be expanded to include early-2021 F-250 trucks. 10R140 transmission failure on a 2021 Ford F-250. Identical to the failure described in 2020 Recall 22V-256. Early 2021 VIN, suspected recall scope error. approximately sometime in January 2025 not exact date.
