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.

Certain 2022-2024 Ford F-150 Lightning BEVs May Have A Battery Defect

Posted on by

A potential safety issue has been identified in a small number of 2022-2024 Ford F-150 Lightning Battery Electric Vehicles (BEVs). The problem affects the high voltage battery cells, which may have a manufacturing defect that can cause an internal short circuit. This defect is due to misaligned electrodes in the battery cells, which can occur over repeated charge and discharge cycles.

The issue was first brought to Ford’s attention in October 2024, when a fire was reported in a 2022 model year F-150 BEV. Further investigation revealed two additional fires in 2022 and 2023 model year vehicles, prompting Ford to launch a broader inquiry into the matter. Although no physical samples were initially available for analysis, Ford’s Field Review Committee authorized a program to collect and evaluate additional samples from the field.

The subsequent tear-down analysis of the returned battery arrays revealed evidence of misaligned electrodes in the high voltage battery cells. The supplier also found that eight stacker machines between two production lines had produced cells with cathode shift, which did not meet the design requirements. This manufacturing concern resulted in overlap that fell short of the required standards. Notably, some of the cells from vehicles that experienced fires were manufactured during this time frame.

On February 18, 2025, Ford learned of a fifth report of a vehicle fire and decided to approve a safety recall. The recall affects certain 2022-2024 Ford F-150 Lightning BEVs, and owners are advised to take precautions until the repair is completed. Specifically, owners should only charge their vehicles to a maximum of 80% battery capacity to minimize the risk of an internal short circuit.

To address this issue, dealers will inspect and replace the high voltage battery array as necessary. Owner notification letters are expected to be mailed on March 17, 2025.
