My truck completely shut down while leaving the shop and I was only going about 6-10mph. The dash alert stated "fuel accessory" or something in orange, sorry, I panicked a little:) I took it to Bradley Ford the next day and they couldn't fix it as they didn't know the issue. This happened a second time, but didn't shut off completely, it just felt like I was running out gas (full tank). I do live in Lake Havasu City, Az and it's hot here so I don't let my truck go below 1/2 tank hoping this will help avoid a major accident. Thank you!

I was turning left from a side street onto a divided highway and stopped in the middle to wait for an opening in traffic. When one came I hit the gas and nothing happened. Pressed it again, to the floor and nothing happened. I then put the truck into reverse to back out of the way of traffic because the truck rolled forward a bit when I attempted to accelerate. I then waited for a very large opening and attempted to accelerate again. Pushed the pedal and again nothing. I then pressed it to the floor and held it there. The truck very slowly began to accelerate and then after about 20 seconds accelerated like normal. The truck seemed normal the rest of the way home.

Due to a defective door (cheap plastic pin), the check engine light comes on with associated warnings on the fuel door not being shut. It is shut but not locked due to the defective pin (I believe plastic) that interacts with the warning light and warning message.

Ford Motor Company has issued a safety recall, identified by letter NEF-107DG and recall number 24V-957, due to the potential failure of the CP4 fuel pump in certain vehicle models. The recall affects the following makes, models, and model years: FORD/F-250 SD (2020-2022), FORD/F-350 SD (2020-2022), FORD/F-450 SD (2020-2022), FORD/F-550 SD (2020-2022), FORD/F-600 SD (2020-2022), FORD/F-650 (2021-2022), and FORD/F-750 (2021-2022). This action addresses concerns that the CP4 pump may fail prematurely, potentially leading to engine stalling and increasing the risk of a crash. Notably, my 2021 Ford F-150 XLT with a 3.0L diesel engine is equipped with the same CP4 fuel pump as the models listed above. As such, it should logically be included in this recall to ensure consistent safety measures and address the risks associated with this known defect.

I've experienced the loss of power during hard acceleration. Right hand turns from a stop feel like the engine has stalled and rolling right hand turns are becoming increasingly more dangerous. Most recently as I was merging onto a highway. Pedal to the floor, the truck initi9ally accelerated for a couple seconds until it stalled to make the truck not only not accelerate but almost made it feel as if I was breaking. This is very dangerous.

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.

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.

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-150 Supercab Diesel verdict →
