2020 MERCEDES-BENZ GLS 580 Recalls — Canada & USA

The 2020 Mercedes-Benz GLS 580 has 7 recalls, the most serious being an improperly secured 48-volt ground connection under the passenger seat that can overheat and start a fire. Three recalls involve occupant restraint. The front airbag wiring harness may be routed incorrectly, and separately, the airbag control unit software may be programmed incorrectly — either problem can prevent the airbags from deploying properly in a crash. The seats themselves also have two issues: certain vehicles were assembled with incorrectly built seats that may not hold an occupant in a crash, and the third-row seatback locks can fail in a crash, leaving rear passengers without proper restraint. On the structural side, the rear door window trim can detach and become a road hazard. There is also a software issue where activating car wash mode can cause the sunroof to close unexpectedly, raising the risk of injury to anyone near the opening.
