2020 FORD F-150 Complaints

The contact’s father owns a 2020 Ford F-150. The contact stated that the check engine warning light was illuminated. While driving at various speeds and accelerating or while idling, the vehicle bucked or jerked. The vehicle failed to accelerate intermittently, causing the driver to make several attempts to restart the vehicle, depress the accelerator, and allow the engine to cool down for the vehicle to accelerate as needed. There was a loud grinding and knocking sound coming from the engine compartment. The vehicle was taken to the dealer, who diagnosed that the engine had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure, and a case was opened. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 55,000.

My truck is a 2020 F150 3.5 eco-boost four-wheel-drive, 41,000 miles I’ve owned the truck since November 20th 2021, the mileage at time of purchase was 28,211. Less than 30 days later I had taken it to the Ford dealership to have the IWE’s replaced and wheel bearings, which is the four-wheel-drive locking hub assembly. It took them over six months to fix it. Now, December 1, 2025 the same problem has returned the IWE’s have failed, when they fail metal shavings goes into the wheel bearings. Mind you this is less than 13,000 miles since the first repair. Upon picking my truck up from Ford on a Friday afternoon at 5 PM, January 9, 2026. Upon start up now, my cam phases are rattling.. I even asked Ford. I lost over seven months of driving my pick up and not being able to use my warranty because it’s set up the dealership for so long. Now it’s out of warranty and I’ve left looking at over $6500 to fix the cam phaser issue that they knew was bad and they didn’t recall them. So as of today, January 11, 2026 my truck has 41,000 miles on it. I have driven it less than 13,000 miles in five years. And I’m not looking forward to having to fix the transmission as well because it has a major issue and that should’ve been recalled as well. Ford is leaving us hanging out there with these trucks that cost over $50,000 and in the end it’s gonna cost us another 20 to 30,000 to fix them. Ford still hasn’t fixed the recall that is presently out as well for the sync and back up camera.

The truck's cam phasers are rattling bad and getting worse. It used to only do it at initial start up in the morning and any time it sat for an hour or more , but now it seems to be rattling on every startup. Ford has newly designed cam phasers, but they are not offering to put those in unless I pay for it.

Front passenger door lock will not function. the lock does not lock or unlock with the key fob or the interior door lock controls.

10 speed transmission, started slipping. And then slamming into gear while it would down shift. We have had 4 rebuilt transmissions put in with Ford. And now the truck just went into the shop again for the same issues. This last time before going into the dealership, felt like the transmission was just going to drop out. It was hard.Do not feel safe in this truck any more. it is not reliable. No warning lights at all.

10 speed TREMIC transmission, the same one covered by NHTSA #24V-208. Transmission hunts for gears, and has dropped from a high gear to first gear without warning. The advisory says that it could drop out of any gear to first gear without warning possibly causing a crash. For some reason, my vehicle with the same transmission and same problems is not covered by the recall.

Vehicle is showing symptoms similar to common reported problems from people who owned Ford F-150 with Eco-boost. Symptoms such as: Engine had difficulty starting Transmission shifting Rattling noises coming out from the engine compartment Oil leaks coming out the tail pipe Gauge is showing engine is over heating Turbo is having a hard time accelerating

The transmission has Harsh, Jerky, clunking shifts. It also has delayed engagement and complete power loss. There is also problems with downshifting from 7th gear to first gear when coming to a complete stop. Vehicle seams to be in neutral then finally shifts to 1st gear before vehicle finally moves.

Transmission shifted from 10th gear to 1st gear at highway speed. Transmission was rebuilt by ford, and is again exhibiting poor/harsh shifting.

Transmission is stalling, jerking, skipping gears and slipping. I have talked to the dealership several times about the transmission slamming really hard in 4th and 8th gear. They would tell me it’s just trying to find the right gear to be in, your battery is causing it or it needs to be reprogrammed. There has never been any warning lights. This truck has spent over 4 months in the shop for drive train issues. New rear end, new drive shaft and a vibration that has never gone away.
