2021 FORD F-150 Complaints

Check engine light went on. Knock sensor failure. Vehicle running rough and knocking. On line lots of people complaining. Gentleman in the service department who works for Ford said that he has been getting a lot of knock sensor failures lately.

When using the window wipers, they become inoperable. Stopping in the middle of the window, pausing when moving, or completely stopping and unable to get them to start moving until they begin to move on their own. This has occurred multiple times and at multiple different speeds of operation for the wipers. This was a previous recall issued by Ford that has been completed on the vehicle yet the same result is occurring.

Vertical Daytime Running Lamp is out and from doing multiple hours of research it looks as if it was a quality control issue. The LED board was not secured internally and it caused an LED to touch the tube and burned it. It is very common on 2021-2023 models and the manufacturer changed it for 2024. Please we need to get this as a recall.

I haven't had a issue yet, but I'm not comfortable continuing to drive my truck with a known safety recall that Ford has no solution for even though it's been a recall for several months. I live in a area with no Ford dealerships, so it's a little difficult to get warranty work done.

The EPAS (Electric Power Assisted Steering) module experienced an internal sensor failure, causing a sudden and complete loss of power steering assist. The vehicle is available for inspection upon request and the EPAS module has been retained. The loss of power steering occurred without warning while the vehicle was in motion, requiring significantly greater physical force to maintain control of the steering wheel. This creates a serious risk of losing vehicle control, particularly at higher speeds, during lane changes, or in emergency maneuver situations. Because the failure occurs randomly and without any prior indication, there is no opportunity to safely prepare or pull over before it happens, putting both the driver and other motorists at risk. Yes. The issue has been acknowledged by multiple Ford dealerships and independent mechanics, all of whom confirmed this is a known and recurring problem with this vehicle’s EPAS system. Numerous online automotive forums also document other owners experiencing the identical failure, suggesting this is a widespread issue rather than an isolated incident. The vehicle was inspected by an authorized Ford dealership, which confirmed the EPAS module failure and acknowledged familiarity with the issue. No warning lights, dashboard messages, unusual sounds, or handling changes occurred before the failure. The power steering loss happened suddenly and without any prior symptoms, leaving no opportunity to anticipate or react to the malfunction before it occurred.

My 2021 Ford F-150 intermittently displays the warning message “Reverse Brake Assist Not Available – See Manual” when the vehicle is placed in reverse. When this message appears, the reverse brake assist / parking collision warning feature is not available, which may reduce safety while backing up. The vehicle was inspected by a Ford dealership. The dealership confirmed DTC U3000:49 in the IPMA module and identified Ford TSB 23-2040 as applicable to the concern. The dealer stated that the repair requires an IPMA software/module update and calibration. The quoted repair cost was approximately $1,100. This appears to be a software/programming-related condition affecting a driver assistance and brake-related safety feature, not normal wear and tear or a failed mechanical component. The warning is intermittent, but it has appeared multiple times. The vehicle is available for inspection upon request. No crash, injury, or fire has occurred. Ford Customer Support was contacted and case number XXX was opened. Ford advised that no active warranty, recall, or customer satisfaction program currently provides repair cost coverage, and that because this involves Reverse Brake Assist, I may choose to file a safety concern report with NHTSA. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After a day of heavy rain, the vehicle stalled at a stop light and would not restart. The steering wheel and transmission locked, preventing the vehicle from being placed in neutral, creating a safety hazard as the vehicle was immobile in traffic. No warning lamps appeared prior to the failure. The vehicle required a tow. The dealer confirmed water had intruded through the passenger side cowl/firewall seam due to inadequate factory sealing, tracking down and pooling directly onto the Body Control Module (BCM) mounted on the passenger side firewall. The BCM failed due to water damage, causing PATS desynchronization and the no-start condition. The BCM failure subsequently shorted out the starter motor. Dealer replaced the BCM, repaired the leak, and replaced the starter. Total repair cost approximately $3,200. Failed components are available for inspection at the dealership. This identical failure; passenger side cowl water intrusion leading directly to BCM damage — is documented across numerous 2021+ F-150 owner forums, indicating a widespread factory sealing defect at the cowl/firewall/inner fender seam junction.

2021 Ford F-150 Lariat, 5.0L Coyote V8, purchased new, now 65k miles. Two interrelated safety defects: OIL CONSUMPTION: On 3/21/2026 at 62k miles, I discovered the engine was critically low on oil. Only 3 quarts drained during a full oil change, against a rated 8.8 quart capacity. The engine had been running on one third of required oil. The onboard oil life monitor showed 9% remaining and gave NO low-oil warning, no warning lights, no alerts. No external leak. On 5/22/2026, Koons Ford Woodbridge formally confirmed excessive oil consumption after a documented oil consumption test. Ford TSB 19-2365 acknowledges this exact defect on the 5.0L Coyote for 2018-2020 model years, attributing it to high intake manifold vacuum during deceleration fuel shut-off pulling oil into the combustion chamber. The 2021 engine is mechanically identical. TRANSMISSION: Hard and slipping gear shifts reported to Ford within months of purchase in 2021. Ford issued multiple software updates over the years to mitigate the behavior, most recently late 2025. Fix was temporary; hard/slipping shifts returned. CATASTROPHIC FAILURE: While awaiting Ford HQ authorization on repairs, the vehicle suffered complete drivetrain failure on Friday night. Engine lost power and transmission failed entirely. I was near home and coasted safely off the road. Had this occurred at highway speed during my daily commute, the result could have been catastrophic. Vehicle towed to Koons Ford Woodbridge. SAFETY CONCERN: This is my only vehicle, used for daily highway commuting. The oil consumption defect provides no warning before engine damage. The transmission has degraded despite years of Ford software patches. The vehicle has demonstrated total drivetrain failure capability with no driver warning. Ford Corporate case opened: CXH-07446845-G0J0K0. Filing to document this at the federal level and add to the existing pattern of complaints. Requesting NHTSA review whether these defects warrant investigation.

Incident Description:The vehicle experienced a complete internal transmission failure while driving, creating a severe and sudden loss of power on the roadway. A professional technician's diagnostic assessment confirmed active fault code P07F7 (Incorrect Gear Ratio 10th Gear) and explicitly cited Ford Technical Service Bulletin TSB #25-2474, pointing directly to a failed internal mechanical CDF clutch drum sleeve.On October 31, 2025, the dealership attempted to patch the issue by replacing only the external electronic transmission solenoids. However, this did not address the true internal mechanical defect, causing the transmission to fail again immediately with the exact same symptoms.Ford has acknowledged this severe design flaw via an internal Customer Satisfaction Program but has strictly capped coverage at 70,000 miles. Because this identical mechanical failure occurred at 81,893 miles, Ford has denied all financial and safety assistance to fix the actual broken mechanical hardware. This widespread manufacturing defect affecting 10R80 transmissions causes vehicles to suddenly lose propulsion in traffic, creating an imminent crash hazard. This campaign must be expanded to a mandatory safety recall.

My 2021 Ford F-150 has been having trouble with the transmission. Hard shifting, shifting to 10th gear at 40mph and unable to downshift after slowing down. I have also had issues with the daytime running lights not working since around 45k miles. My truck only has 59K miles at the time of me typing this.
