2020 FORD F-150 Complaints

Transmission failure vehicle when pulling into traffic/or road while up shifting the trans would have harsh shift and would slip as if not in gear the engine would rev rpm’s and slam hard into gear usually 2nd gear through 7th gear. Sometimes while driving say going downhill the transmission would down shifting from 10th gear to 8th gear hard, sometime it would down shift on the display to first gear and seemingly be coasting until it would just up shift to any gear it chose. My safety and that of my passengers was that while merging into traffic with the transmission slip or hunting for gears caused other traffic to brake, slow or avoid my vehicle.There were never any warnings on the display dash. Manufacturer Dealer had 7 week wait list for appointments but was scheduled. Manufacturer Dealer mechanic tested vehicle and determined code o76f present for 7th gear leading to failure of transmission and recreated the same failure results while test driving. Recommended transmission replacement and has since replaced the transmission with new transmission at my expense of $8630.00- taxes plus charge of $199.00 for diagnostic work.

Issue Description: The radio/infotainment system intermittently cuts out and produces loud static noises while driving. The issue occurs without warning and happens repeatedly. Safety Concern: The sudden loss of audio and loud static creates a distraction while driving and can interfere with hearing important external sounds (traffic, emergency vehicles, etc.). The unpredictable nature of the problem increases driver distraction and could contribute to unsafe driving conditions. Conditions: Occurs while driving (various speeds) Happens intermittently No clear trigger

Vehicle is having erratic downshifting at highway speeds causing it to drop gears and brake harshly then violently accelerate. The transmission was already replaced by the dealer in 2025. Dealer is reporting they cannot get the vehicle to duplicate the issue but this has posed a great safety risk of injury for my family.

Transmission issues: Harsh, erratic shifting (jerking, lurching, and hesitating, especially when cold). Delayed engagement (2 to 3 seconds before engaging Drive or Reverse). Gear slippage accompanied by prominent clunking. Severe risk of total transmission failure if left unaddressed.

10r80 transmission shifts from 7th & 9th gear to 2nd gear causing truck to jerk and over rev. there were two mil lights local shop was able to read and reset once and cleared codes. This just recurred and truck was not able to be driven. Ended up replacing transmission same week as this problem started. New transmission has been fine since.

I was driving and slowing down for a stop sign and the engine shut off by itself while still moving at appx 10-15mph. The display had several warning lights appear, and the message "Auto Start Stop, Shift to P, Then Restart Engine". I have the Auto Start Stop disabled on my vehicle, so there was no reason for my engine to shut off while decelerating. I searched online for potential causes and discovered that there are numerous incidents of this happening (engine shutting off while moving) to drivers that have deactivated the auto start stop on their vehicles.

* This complaint concerns a catastrophic failure of the transmission in my vehicle. This defect was first reported to a Ford dealer while still within the 5-year/60,000-mile powertrain warranty (Jan 3, 2023, at 58,679 miles; Invoice #XXX). * The condition worsened. Between July 2024 - Jan. 2026, I received 7 digital "Service Engine Soon" warnings via the Ford App. My dealer advised that the vehicle was "OK to drive" as long as the light (which never stayed on) was not flashing. I was told diagnostics could not be made unless the light was active at the dealership. Jan 16, 2026, the light came on; I was able to take the truck to the dealer. A fault code was finally captured, but the dealer reported a two-month service backlog. I could not wait that long. *Feb 2026, I established a clean engine baseline. I spent $833.15 to replace O2 sensors (EJ’s Automotive) to rule out engine-related performance issues. During this service (at 103,431 miles), an inspection confirmed metallic clutch material contamination in the transmission fluid only 10,248 miles after a 2nd professional flush. This failure occurred despite a total maintenance investment of $11,533.80 across 21 service visits. * This failure resulted in a dangerous Loss of Motive Power, creating a collision risk. The vehicle is currently grounded and completely inoperable. The dealership verbally designated the vehicle as VOR due to the confirmed diagnosis, only to contradict that status by claiming it was "driveable" after I declined a $15,000 quote for a teardown to diagnose the issue. * Since the truck can no longer tow, 2 third-party transports for a horse and a trailer relocation are necessary. The failure has also resulted in a total parasitic battery drain. The tailgate latch and door locks are inoperable, suggesting the transmission fault is interfering with module communication. This is consistent with the root cause Ford has acknowledged in TSBs 24-2101 and 25-2126 involving the CDF clutch drum sleeve. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF

The transmission has a history of harsh shifting and slipping. At 101,600 miles being told this is a known issue with the transmission and likely needs to be replaced.

This car has tail lights that are in operable, and do not work, it has almost caused a quite a few near accidents, would like to see this resolved soon.

I took it to the ford dealership, they said the transmission needed to be replaced
