Ford Motor Company is recalling 42,784 Mustang Mach-E electric vehicles in the United States after identifying a potential defect involving the rear differential that could lead to a loss of drive power or unintended vehicle movement.
The recall affects certain rear-wheel-drive Mustang Mach-E models from the 2021, 2022 and 2023 model years.
According to the U.S. National Highway Traffic Safety Administration (NHTSA), the affected vehicles may have a rear differential pinion shaft that can fracture due to bending fatigue.
If the component fails, the vehicle could lose propulsion or move unexpectedly while parked if the parking brake is not engaged, increasing the risk of a crash.
Investigation Identified Fatigue Failures
According to NHTSA documents, Ford’s Product Development team began investigating the issue after analyzing a failed rear differential recovered from a 2023 Mustang Mach-E in Europe.
Subsequent laboratory examinations of additional warranty-returned components between March and May 2026 found evidence of bending fatigue in multiple rear differential pinion shafts.
The investigation also included two previously returned differentials analyzed by the vehicle’s primary drive unit supplier in 2025, which showed similar signs of fatigue failure.
Customer Notification
As of June 11, 2026, Ford was aware of 62 warranty claims related to the issue.
Owners of affected vehicles will begin receiving notification letters from July 13, 2026, instructing them to take their vehicles to authorized Ford or Lincoln dealerships for inspection.
If required, repairs will be completed free of charge.
