10R80 Transmission Rough Shifting and Delayed Acceleration
The 10-speed automatic (10R80) in the 2022 Expedition exhibits harsh shifting, delayed gear engagement, and sudden power loss during acceleration. Many owners describe the truck as lurching or slamming between gears, especially during towing. Ford recalled some 2021-2022 Expeditions for shifting issues.
Ford issued recall 22V346 and multiple TSBs for the 10R80 transmission. The dealer will reflash the PCM with updated shift calibration. Severe cases require valve body or solenoid pack replacement. Always use the specified Mercon ULV fluid.
Est. Cost: $0 - $200 for reflash; $1,500 - $3,500 for valve body repairFront Brake Line Contact with Air Cleaner Pipe (Recall)
The front brake lines may contact the engine air cleaner outlet pipe and become abraded over time, potentially causing a brake fluid leak. Reduced brake fluid leads to reduced braking capability and longer stopping distances.
Ford issued a recall for 2022-2024 Expedition and Navigator vehicles. The dealer will inspect the brake lines for damage and reroute or replace them free of charge. If brake fluid is low or the brake warning light is on, do not drive the vehicle.
Est. Cost: Covered under recallTrailer Brake Software Failure (Recall)
A software error can prevent a towed trailer equipped with electric or electric-over-hydraulic brakes from braking when the Expedition brakes. This significantly extends stopping distance while towing and increases crash risk.
Ford issued a recall affecting 391,836 vehicles to update the trailer brake controller software. Contact your dealer to check your VIN. Until the software is updated, test trailer brakes before every towing trip and maintain extra following distance.
Est. Cost: Covered under recallMoonroof Wind Deflector Detachment (Recall)
The moonroof wind deflector clips may be inadequately attached to the moonroof frame, causing the wind deflector to detach from the vehicle at highway speeds. The detached deflector becomes a road hazard for following vehicles.
Ford issued a recall to inspect and reattach or replace the moonroof wind deflector clips with an improved design. Contact your dealer to verify your VIN.
Est. Cost: Covered under recallRearview Camera Image Delay/Freeze
A software error can cause the rearview camera image to delay, freeze, or not display at all when the Expedition is in reverse. Some owners report the camera showing a frozen image from a previous backing event rather than a live feed.
Ford issued a recall for 2021-2024 Expedition vehicles to update the camera system software. The fix may also be available as an over-the-air update. Contact your dealer to verify your VIN.
