2021 FORD F-150 Complaints

rear glass window completely shattered for no apparent reason while sitting in parking lot parking car. recent snow and outdoor temps about 26 degrees. had driven the car a quarter mile with rear defroster on.

-The hub bolt in the rear axle broke. Truck had to be towed to dealership. Problem was confirmed by dealership. There was no warning lamp and only found out due to flat tire. -In 12/2022, power train failure left vehicle "dead" in the middle of the highway with family of four stranded 400 miles away from home.

The passenger side day time running light is dimmed drastically and almost not visible anymore on the upright section. After doing research , this seems to be a very common issue and not a cheap repair. Some states day time running lights are mandatory to work to pass inspection. Ford has not acknowledged this issue and/or making profit from changing out the whole headlight assembly to fix. It seems like it is a bad design or low quality product for a supposed safety issue.

I am reporting a serious safety issue with my 2021 Ford F-150. This truck has already been subject to multiple recalls, yet the problems have continued. On several occasions while driving, the truck has suddenly shut off without warning, causing a complete loss of power while the vehicle is in motion. This has happened while my family and I were in the vehicle and has nearly resulted in a serious crash. Losing power in traffic without warning creates an extremely dangerous situation and has put my family’s lives at risk. A vehicle shutting off while being driven is a major safety hazard. Despite multiple visits for service and ongoing recall issues, the problem has not been resolved, and the truck continues to fail in a way that could easily lead to a catastrophic accident.

Was driving and all the sudden the steering went out. Was really hard to steer and almost crashed. Very dangerous. Came up "Steering Assist Fault"

1. Electrical System Failure: While traveling on highway, alternator failed suddenly within 2 minutes of “service soon” and “check electrical system” warnings. Caused complete loss of motive power, electronic parking brake locked up while driving, loss of power steering, all gauges failed, transmission shifted into park while in motion. Battery was damaged (“fried”). Engine continued running for several minutes after stop without ability to shut off ignition. Incident documented by Ohio State Highway Patrol. 2. Seat Belt Issue: Driver-side seat belt interlock sticks in unlocked position, creating risk of failure to lock during a crash. 3. Electronic Parking Brake: Intermittently engages while vehicle is moving downhill to a stop (mostly at or below 5 mph). Parking brake light flashes three times then turns solid while in motion. Ford TSB indicates vehicle not eligible for related recall. 4. Infotainment System: Intermittently freezes, requiring forced reboot. Preceded by audio glitches, laggy dash computerized systems. 5. Transmission: Severe clunk and physical jolt when decelerating from ~30 mph to 8 mph. Also occurs during acceleration, particularly upshifts from 2nd to 3rd and 3rd to 4th gears, more pronounced when turning. 6. 4WD System: Intermittently fails to disengage from 4WD HI to 2WD HI. “Failure to shift” message appears several minutes after command to return to 2WD HI. 7. Front Differential/Axle: Previously, faulty front differential housing fractured due to system malfunction, causing intermittent loss of front driveline engagement in 4WD LO (250-500ms delay then re-engagement under throttle). Ford replaced front differential and axle under warranty after vehicle out of service for 2.5 months.
