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.

Nov 30, 2025Transmission & drivetrain

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.

Hi. I took my 2021 f250 6,7 to the ford dealership as it was having trouble starting, and just wasn’t running great. They changed the batteries, and told me it was a NOX sensor. So I went and got my truck to fix the sensors myself; because they wanted to charge me close to 3 grand. The next day I got up, lo and behold it wouldn’t crank. I had to have it towed back to the dealership. I tested codes before I had it towed, and took a video of it not cranking. The following codes showed. P2291 PCM - Injector Ctrl Press Too Low - Engine Cranking P2209 PCM - NOx Sens Heater Sense Circ Range/Perf Bank 1 Sens 1 U029D PCM - Lost Comm With NOx Sensor A P2535 PCM - Ignition Switch On/Start Pos Circ High U300A BCM - Ignition Switch It’s been in the shop a week , they called Friday saying it was starting, and there was nothing wrong with it. So I replied with all the codes, and told them there was definitely something going on. So they checked it again Monday and it wouldn’t start. Now today (aug 5 tues.) they say it may have a vacuum leak. Although non of the codes point to vacuum leak. I have no idea what to do now.

I hit an elk at 65 mph while pulling a flatbed trailer loaded with 4000 lbs of hay. The crash warning light did not come on nor did the air bags deploy. The whole front end of the truck is badly damaged. I contacted my local Ford dealer with this information and was told by the service agent that the body shop will handle this. As my concern is how hard do you have to hit something to get the airbags to deploy. I’m concerned for my safety while driving this truck again if it can be repaired. I’m taking it to the repair shop today. I wanted to report this as Ford will be ZERO help moving forward.

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.

The back up camera and detection system glitches out when the weather is hot outside. When the cameras goes from working to not working or giving glitching screen effects it really affects the safety of being able to see what’s behind you while backing up. I’ve had no system alerts on this issue it just has a mind of its own. There is a recall out for this issue but I was told it was a vin specific issue and that’s not the case. There is a clearly a problem with the software that’s affecting my same year model.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2021 Ford F-250 Supercab verdict →
