Ford Explorer Axle Problem
Certain 2020-2022 Ford Explorer Vehicles May Still Be at Risk

A critical issue affecting certain 2020-2022 Ford Explorer vehicles has come to light, despite previous repair attempts under recalls 23V-199 or 22V-255. The problem lies in the rear axle horizontal mounting bolt, which may fracture and cause the driveshaft to disconnect. This can lead to a loss of forward power, increased risk of crash and injury, and even unintended vehicle movement.

The root cause of the issue is attributed to a software tool malfunction that failed to upload the correct software update to the vehicle during previous repair attempts. As a result, the underlying condition specified in Safety Recalls 23S16 / 23V-675 and 22S27 / 22V-255 may still exist, putting drivers and passengers at risk.

The Technical Explanation

Affected vehicles were built with a 3-point mounted axle design, which can lead to a fracture of the rear axle horizontal mounting bolt. When powertrain torque is applied through the driveline, it causes axle rotation, exerting a bending force on the rear axle bolt. Repeated peak torque events, typically experienced during launch events, can cause fatigue failure of the bolt. This can result in a loud, grinding, binding, or clunking noise, as well as severe vibration.

The Consequences

If the rear axle bolt breaks, the driveshaft or half-shafts may become disconnected, leading to a loss of forward power and transmission torque to the rear wheels. This increases the risk of crash and injury. Furthermore, if the parking brake is not applied, the loss of primary park torque can allow the vehicle to roll in park, increasing the risk of crash and injury.

The Solution

To correct the problem, dealers will update the powertrain control module (PCM) software. Ford’s number for this recall is 25S22, and the NHTSA campaign number is 25V-166. It is essential that owners of affected vehicles take immediate action to have their vehicle repaired to prevent any potential accidents or injuries.
