Ford Recalls 86,543 Mustang Mach-E EVs Over Loose Rear Window Trim Risk
Ford Motor Company announced on August 3 that it will recall 86,543 Mustang Mach-E electric SUVs in the United States. The recall addresses a defect where the rear side quarter window trim may become improperly secured and detach while the vehicle is in motion, potentially striking other vehicles and increasing the risk of a crash. The recall covers 2023, 2024, and 2025 model-year Mustang Mach-E vehicles produced between February 17, 2023, and October 8, 2024.
Process Change at Supplier Led to Insufficient Adhesive Curing, Issue Now Resolved
Ford identified the root cause of the recall as a new assembly jig introduced at the supplier’s factory, Saint-Gobain Mexico, in February 2023. While the jig improved production efficiency, it reduced the installation time for the rear side quarter window trim, preventing the adhesive primer from curing properly. This resulted in insufficient bonding strength between the trim and the window glass. Official documents from the National Highway Traffic Safety Administration (NHTSA) confirm that the shortened installation time led to inadequate adhesive curing, which is the primary cause of the trim detachment.
Ford began receiving reports from owners in May 2024 regarding loose or detached rear side quarter window trim on 2023 to 2025 model-year Mustang Mach-E vehicles. As of the recall announcement, Ford had received 219 such reports but stated it was not aware of any accidents or injuries related to this defect. Saint-Gobain Mexico addressed the issue in September 2024 by implementing a 30-second timer on the assembly jig to ensure the adhesive had sufficient time to cure, resolving the bonding failure.
