2014 MERCEDES-BENZ GL550

I recently purchased my Mercedes from Auto Boutique in Pearland, Texas (713) 352-0777. 1.The vehicle's air suspension system is constantly grinding, and moving/adjusting while being driven. It feels like the vehicles fame is off balance. 2. The back camera system does not work unless the radio is turned on; which is very alarming not to mention dangerous. 3. All the tires are registering improper inflation errors even though no air has been added or removed. I took the vehicle back to the place of origin; but they are not Mercedes Certified to address the issues. I am terrified to drive the vehicle, and it stays parked in the garage

The manufacturer was notified of the failure and informed the contact that the vehicle was not covered under TSB Number: 10233794. The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 104,000.

I HAD JUST ARRIVED HOME. THE CAR WAS OFF AND I WAS PARKED IN MY GARAGE. I OPENED THE DOOR BUT IT DIDN'T OPEN ALL THE WAY TO THE FIRST HINGE. MY HAND WAS IN THE DOOR AS IT SLOWLY STARTED TO CLOSE. THE DOOR CAUGHT SLIGHTLY AND THE SOFT CLOSE FEATURE ACTIVATED. MY THUMB WAS CAUGHT IN THE DOOR AND WAS CRUSHED AS THE DOOR SEALED COMPLETELY CLOSED WITH THE SOFT CLOSE FEATURE. I WAS UNABLE TO OPEN THE DOOR DURING THIS TIME. I WAS YANKING ON THE DOOR HANDLE TRYING TO OPEN THE DOOR TO FREE MY THUMB BUT THE DOOR WOULD NOT OPEN UNTIL THE SOFT CLOSE WAS COMPLETE. AS A RESULT MY THUMB WAS CRUSHED. I BELIEVE THAT THIS A DESIGN FAULT WITH THE VEHICLE. THE FACT THAT THERE WAS NO SENSOR TO DETECT SOMETHING IN THE DOOR AS WELL AS NOT BEING ABLE TO OPEN THE DOOR AT ANY POINT DURING THE SELF CLOSE PROCESS PRESENTS MANY SAFETY ISSUES! I REACHED OUT TO MERCEDES DIRECTLY AND THEY SAID AFTER AN EVALUATION THAT THE VEHICLE WORKS THE WAY IT'S DESIGNED AND THAT THE DOOR COULD OPEN DURING ANYTIME OF THE SOFT CLOSE FEATURE. I MADE A SHORT VIDEO SHOWING THAT IN FACT YOU CAN NOT OPEN THE DOOR DURING THE SOFT CLOSE PROCESS. MY FINGER WAS NOT BROKEN BECAUSE I CLOSED THE DOOR ON IT! THE DOOR WASN'T CLOSED ALL THE WAY, IT HAD ONLY JUST SLIGHTLY LATCHED AND WAS THEN CRUSHED BY THE SOFT CLOSE. I EXPLAINED TO MERCEDES THAT THIS WAS VERY DANGEROUS ESPECIALLY WITH MY 3 AND 5 YEAR OLD. IF IT CRUSHED MY THUMB IT WOULD BREAK THEIR HAND!! AFTER I DISPUTED THAT YOU CAN'T OPEN THE DOOR SOMEBODY HIGHER UP AT MERCEDES CALLED ME AND SAID THAT I WAS CORRECT YOU CAN'T OPEN THE DOOR DURING THE SOFT CLOSE AND THAT I WAS RIGHT BUT THAT IS THE WAY THE VEHICLE IS DESIGNED THEREFORE IT'S OPERATING CORRECTLY. WHEN I ASKED WHAT THEY WOULD DO HE SIMPLY ASKED WHY DON'T I JUST GO AND BUY A NEW CAR WITHOUT THE FEATURE!! I EXPLAINED THAT I DIDN'T FELL LIKE SPENDING ANOTHER $100 000.00 WHEN MY CAR IS ONLY 4 YEARS OLD!

DAIMLER AG, (DAG) THE MANUFACTURER OF MERCEDES-BENZ VEHICLES, HAS DETERMINED THAT ON CERTAIN GLE, GLS AND GLE COUP VEHICLES (166, 292 PLATFORM) WITH THE ACTIVE CURVE SYSTEM (ACS), THE OIL IN THE ACS'S OIL RESERVOIR COULD START FOAMING UNDER DYNAMIC DRIVING SITUATIONS IN COMBINATION WITH AN OIL LEVEL BELOW MINIMUM. THE OIL FOAM MIGHT LEAK OUT OF THE OIL RESERVOIR THROUGH THE VENT HOLES IN THE SEALING CAP. DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT. AS A PRECAUTIONARY MEASURE AN AUTHORIZED MERCEDES-BENZ DEALERSHIP, WILL CORRECT THE OIL LEVEL IF NECESSARY AND REPLACE THE SEALING CAP OF THE OIL RESERVOIR WITH AN OPTIMIZED SEALING CAP TO PREVENT OIL FOAM LEAKAGE. SAFETY RISK: DEPENDING ON THE ORIENTATION OF THE VENT HOLES IN THE SEALING CAP, LEAKING OIL COULD SPRAY ONTO HOT SURFACE COMPONENTS OF THE EXHAUST SYSTEM. IN SUCH A CASE THE RISK OF A FIRE CANNOT BE RULED OUT.

THE REAR HEADRESTS IN THE MODELS THAT HAVE THE EZ FOLD SYSTEM IN THE 2014 GL550 WILL NOT COME OUT, NOR DO THE HEADRESTS TILT BACK TO A COMFORTABLE POSITION FOR CHILDREN. IN THE MERCEDES FORUMS, THERE ARE DOZENS OF COMMENTS ON THIS AND I HAVE ATTACHED PHOTOS FROM ONE OF THESE THAT MIMICS WHAT MY CHILDREN, 9 & 13 ARE EXPERIENCING - UNABLE TO SIT VERY COMFORTABLY IN THE BACK SEAT, AS THE HEADREST PROTRUDES TOO FAR OUT WHERE THEIR NECKS ARE TOO CRANKED FORWARD, OR HEAD IS NOT IN A GOOD POSITION. I AM SEEKING A FIX WHERE THE HEADREST CAN TILT BACK LIKE THE ONES IN THE VEHICLES WITH MANUAL FOLDING REAR SEATS. TAHNK YOU.
