Known issues on the 2010 GL550. Three recalls are listed for the 2010 GL550. A pair of them concern the brake booster, whose housing on certain vehicles could trap moisture and corrode until brake performance dropped or the brakes failed outright; drivers were advised to leave those vehicles parked until a dealer had inspected them. The third covered certain all-wheel-drive versions with a driver's frontal air bag inflator that could rupture when deployed, sending metal pieces into the cabin. Two of the three owner complaints involve air bags. Separately, three complaints on the 2010 GL-Class line mention suspension, structure and the gasoline fuel system. Booster, air bag and suspension service is documented with specifications and diagnostics.
