2017 Mercedes-Benz GLS550: complaints, problems and recalls

I LOWER THE PASSENGER CAR WINDOW WHEN I ENTERED THE CAR IN A VERY HOT DAY AND THE WINDOW GLASS EXPLOTED. I TOOK THE CAR TO THE DEALER AND THEY SAID IT WAS NOT A CAR DEFECT. HOWEVER, THE CAR WINDOW GLASS JUST EXPLOTED JUST BY LOWERING IT.

I PURCHASED A 2017 GLS 550 IN JANUARY 2018 FROM LOEBER MOTORS IN LINCOLNWOOD ILLINOIS. THE STICKER ON THE VEHICLE REPRESENTED THAT THERE WERE 'ALL SEASON' TIRES ON THE VEHICLE. AFTER NUMEROUS GUARANTEES FROM THE SALESMEN, I WAS ASSURED THAT THE VEHICLE WOULD BE 'SAFE' ON THE FACTORY TIRES AS THEY WERE REPRESENTED AS ALL SEASON. IT WAS NOT UNTIL I FOUND MYSELF DRIVING THROUGH A SPRING SNOWSTORM IN WISCONSIN THAT I REALIZED THAT THERE WAS SOMETHING TERRIBLY WRONG WITH THE WAY THE VEHICLE WAS HANDLING IN THE STORM.

We had our Mercedes GLS550 2017 with 59,295 overheat and call for immediate shut down on the Massachusetts Turnpike with my wife and child in the car. It was quite a dangerous situation because the failure caused by hose assembly 166-830-15-00 clamp (as described by the dealer as the reason for the loss of fluid and hose failure) caused almost an immediate overheating. The service advisor stated that it is "a quite common failure". I was quite suspicious, because just 11 days prior and 138 miles prior they had performed an Oil Change (Servic…

Reported: 2017-02-08 (February 8, 2017)

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2017 GLE 400 4Matic, GLE 350 4Matic, GLE 350, GLE 550E 4Matic, GLE 63 AMG, GLE 63S AMG, GLE 43 AMG 4Matic Coupe, GLE 63S AMG 4Matic Coupe, GLS 450 4Matic, GLS 550 4Matic, and GLS 63 AMG 4Matic vehicles. In certain types of crash events, the center console may unlatch, allowing the objects within to fly around the cabin. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 201, "Occupant Protection in Interior Impact."

Consequence: In the event of a crash, if objects are not secured within the center console, they may strike the vehicle occupants, increasing their risk of injury.

Remedy: MBUSA will notify owners, and dealers will modify the center console so that it remains latched in a crash, free of charge. The recall is expected to begin in early March 2017. Owners may contact MBUSA customer service at 1-800-367-6372.

Reported: 2017-12-18 (December 18, 2017)

The rear passenger door on the driver side may indicate that it is locked, when it may not be. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 206, "Door Locks and Door Retention Components."

Consequence: If the door appears to be locked, the door may be unintentionally opened, increasing the risk of injury.

Remedy: MBUSA will notify owners, and dealers will inspect the left rear door lock, replacing it as necessary, free of charge. The recall is expected to begin in January 2018. Owners may contact MBUSA customer service at 1-877-496-3691.

Consequence: The leaking oil in the presence of an ignition source can increase the risk of a fire.

Remedy: MBUSA will notify owners, and dealers will correct the oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out, free of charge.
