Common problems reported by 2021 Ford F-250 owners, with recommended fixes and estimated repair costs.
Transmission Shifting Problems
Powertrain complaints related to the 10-speed TorqShift automatic transmission top the list for the 2022 F-250. Owners report rough shifting, delayed gear engagement, and occasional gear hunting under load. Towing exacerbates the issue significantly.
Have the dealer reprogram the PCM with the latest shift calibration and check for applicable TSBs. Ensure the transmission fluid level is correct and use only Ford-specified Mercon ULV fluid. Severe cases may require valve body or solenoid pack replacement.
Est. Cost: $0 - $200 for reflash; $1,500 - $3,500 for valve body repairDriveshaft Damage from Heat Insulator Contact
Underbody heat and noise insulators may loosen on certain 2017-2022 F-250 and F-350 Super Duty vehicles and contact the aluminum driveshaft. The contact can damage and eventually fracture the driveshaft, causing a sudden loss of drive power and a significant road hazard.
Ford issued a TSB to inspect and secure or replace the underbody heat insulators and inspect the driveshaft for damage. If the driveshaft is scored or cracked, it must be replaced. This should be covered under warranty.
Est. Cost: $100 - $300 for insulator repair; $800 - $2,000 for driveshaft replacementTrailer Brake Controller Malfunction
The integrated trailer brake controller may fail to properly engage trailer brakes, malfunction intermittently, or display error messages. Some owners report the trailer brakes applying unevenly or not at all during towing, significantly increasing stopping distances.
Ford issued a recall addressing trailer brake software errors. Have the dealer update the trailer brake controller module software and inspect the wiring harness to the trailer connector. Test trailer brakes before every towing trip.
Est. Cost: $0 for software update; $200 - $600 for wiring/module repairPremature Brake Pad Wear and Noise
Owners report front brake pads wearing out prematurely, squealing, screeching, or grinding, and vibrations in the brake pedal or steering wheel during braking. The heavy weight of the Super Duty accelerates brake wear, especially when towing.
Replace front brake pads and rotors with heavy-duty aftermarket options rated for towing. Inspect the caliper slide pins for proper lubrication and check for caliper drag. Consider upgrading to slotted or drilled rotors for better heat dissipation during towing.
Est. Cost: $400 - $900 for front brake job6.7L Power Stroke EGR Valve Coolant Leak
The exhaust gas recirculation (EGR) valve and cooler on the 6.7L Power Stroke diesel engine can develop coolant leaks, producing white smoke from the tailpipe and a sweet coolant odor. If unchecked, coolant can enter the cylinders and cause hydrolock.
Replace the EGR valve and cooler assembly. Inspect the EGR cooler for internal cracks. Some owners opt to install an EGR delete kit where legally permissible. Monitor coolant levels closely and address any loss immediately.
Est. Cost: $700 - $1,700 for EGR valve/cooler replacement
