Rear Axle Mounting Bolt Fracture
The rear axle horizontal mounting bolt can fracture and cause the driveshaft to disconnect from the rear axle. This can result in a sudden loss of power to the rear wheels and a potential road hazard from a dragging driveshaft. A recall was issued affecting thousands of 2020-2022 Explorers.
Ford issued recall 22S46 to inspect and replace the rear axle horizontal mounting bolt. Contact your dealer to verify if your VIN is affected. The repair is performed free of charge.
Est. Cost: Covered under recallTransmission Erratic Shifting and Fluid Venting
The 10-speed automatic transmission can shift erratically, exhibit delayed gear engagement, or vent transmission fluid externally. Owners report the vehicle jerking between gears at low speeds, and some have found fluid puddles under the vehicle from the transmission vent.
Ford issued a TSB for 2020-2022 Explorer/Aviator addressing the erratic shifting with a PCM recalibration. The fluid venting condition may require seal and gasket replacement. If internal damage has occurred, the valve body or transmission may need replacement.

Est. Cost: Covered under recallTransmission Park Gear Disengagement (Rollaway Risk)
A loose bolt inside the transmission may prevent the park gear from fully engaging even though the shifter indicates 'PARK.' This creates a rollaway risk when the driver exits the vehicle, and Ford recalled over 250,000 Explorers for this defect.
Ford issued recall 23S01 to inspect and tighten the transmission internal bolt. Always use the parking brake as a secondary precaution. Contact your dealer to verify your VIN status.
