2020 FORD F-150 Complaints

Transmission is being replaced for a 2nd time due to erratic downshifting at highway speeds. Going from 10th to 1st to 5th and back to 10th gear. Then loss of power.

Transmission shifting erratically between gears, sometimes shifts hard enough to jerk the truck. I have searched Ford owner databases and this is a common problem with the 10R80 transmissions

TRANSMISSION STALLED INTO FIRST, WOULDNT ALLOW YOU TO PUT VEHICLE INTO GEAR UNLESS YOU TURNED VEHICLE OFF AND BACK ON. FORD SERVICE CENTER VERIFIED CONCERN IN PARKING LOT. VEHICLE STARTS IN FOURTH GEAR AND LUNGES VERY ROUGH. NO DTC. FLUID LEVEL FULL BUT VERY DARK WITH FINE METAL CONTAMINATION PRESENT. PERFORM CDF TEST. RESULTS FAIL. CDF BUSHING HAS SLIPPED COMPLETLY BLOCKING FLUID PORTS. ALSO SUSPECTED HUB BASKET HAS WORN GROOVED FROM F CLUTCH APPLICATION CAUSING FINE METAL IN FLUID. OVERHAUL NEEDED FOR REPAIR Safety concerns: my truck stalled in an intersection which put me, my pregnant wife, and our [XXX] daughter at risk of being hit by another vehicle. After speaking to multiple services centers (both Ford and 3rd party), I was told by *all* of them that they've been replacing 10-speed Ford transmissions like crazy these past few months. My vehicle is currently at a certified Ford dealership pending repair. Currently contesting a denial in financial assistance considering the vehicle is within the 5 year powertrain warranty (the vehicle had an initial 5 year, 60,000 mile warranty and my truck is at 72,200 miles). No warning lamps or messages occurred until the moment the problem occurred. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving at highway speeds and my truck began to shake violently and very loud banging sound. Slowed down to pull over on the highway. Found driveshaft broken in half with gas dumping out of the fuel tank. Broken driveshaft damaged heat shield for gas tank, punctured gas tank and dented/broke clips on exhaust. Very lucky back driveshaft didn’t hit pot hole and leaking gas didn’t start a fire. Stranded on side of road for hours. Sent my vin to the dealership and they said my was not under the recall #21S56 even tho it was built after known driveshaft issue and clearly the insulator caused the issue.

I am writing to report a serious safety issue with my Ford F-150. On March 15th, 2025 while driving on State Route 167 - 410 in heavy rain, my vehicle experienced an intermittent engine shutdown while in motion. Second time happened to my wife while leaving the neighborhood on March 18th, 2025. Specifically, the engine completely shut off while driving at 40 mph. This occurred despite the Auto Start-Stop feature being manually disabled. Upon the engine shutdown, the Driver Information Center (DIC) displayed the message, "Auto StartStop Shift to P, then Restart Engine." The car did not lost power and I needed to do a full stop, shift to P, restart and switch back to D to continue driving. This malfunction occurred under hazardous conditions, specifically during heavy rain on a freeway. The sudden loss of engine power created a highly dangerous situation, placing myself and other drivers at significant risk. I am deeply concerned about the potential safety implications of this issue. The fact that the engine shut down while driving, even with the Auto Start-Stop feature disabled, suggests a critical malfunction that requires immediate attention. Despite having an extended warranty and the serious nature of this safety concern, the service department from Sunset charged me money for an unsuccessful diagnosis after two days, with service advisor unable to identify or replicate the problem.

Transmission shifts very hard out of 2nd 3rd and 4th gears up and down. Took for service and was supposedly fixed. After about 3k miles it started again. Ford says fixing is my cost even though they sold me trash

Transmission engages and disengages periodically as i slow down or come to a stop. Shifts erratically while driving from 6 gear to 4th gear , and when accellerating it hesitates from 2nd to 3rd gear, then shifts hard to 4th gear where i have to press on the brake to stop it. My concern is when it down shifts hard while in traffic, almost got rear ended one time. Just not safe to drive, ive have this truck for less than 5 months now. Preowned with less than 100k miles, just doesnt make sense..
