The 2019 Mercedes-Benz GLC350e has 5 recalls, the most serious involving the front roof panel between the windshield and panoramic sunroof, which can detach from the vehicle and become a road hazard for other drivers.
A related roof panel concern affects vehicles that had a prior repair attempt: if that repair did not bond the panel correctly, it can also detach while driving. On the occupant safety side, the electric pre-safe system and seatbelt pretensioners may fail to activate in a crash, leaving occupants with less protection than expected. There is also a passenger airbag concern where the dashboard indicator can incorrectly show the airbag as active when it is not, leaving a front-seat passenger unaware the bag will not deploy in a crash. Finally, the passenger-side sun visor on some vehicles carries airbag warning labels printed in a foreign language, which may prevent occupants from understanding the risks to children seated in front.
