A multitude of Mercedes-Benz GLE and GLS models have been recalled in the United States because the fastening on the rear door window trim may not meet production specifications.

A National Highway Traffic Safety Administration (NHTSA) recall notice reveals that the rear window trim bar might separate from the vehicle while driving. If this were to occur, it could increase the risk of a crash and could pose a risk of injury to other road users.

Mercedes-Benz has revealed that a deviation in the assembly process means the trim bars may not have been fastened in accordance with current production specifications. Owners will not receive a warning if the trim bar is about to separate while driving.

The recall impacts Mercedes-Benz GLE 350 models (86,652 units), the GLE 400e (1 unit), GLE450 (15,558 units), GLE 53 (5,375 units), GLE 580 (2,118 units), GLE 63 S (1,565 units), GLS 450 (41,532 units), GLS 580 (5,161 units), GLS 600 (673 units), and GLS 63 (2,365 units), all of which were built between May 20, 2019 and April 7, 2022.

Mercedes-Benz started to receive isolated field reports in the United States in March 2021, saying that trim bars were loose or had detached from a vehicle while driving. An investigation was immediately launched to retrieve damaged parts for analysis. The automaker concluded that the window trim detachments were not the result of a design or product specification error but issued a recall anyway.

Owners will be notified before November 11, 2022. Dealers will check the installation of the trim bars on the rear door windows and rework them if necessary.
