2013 Mercedes-benz GL-Class Complaints

Driver's side tire continues to leak air - note low tire pressure even with new tire replacement. Airmatic Suspension failure. Rear airbag suspension airbag. Compression also failed. Several complaints to dealer advising the car was bouncing up and down while in drive. Took vehicle to the shop with suspension complaints at the end of April 2021. We were told they did not find an issue with suspension but saw an issue with the sway bar. This cost $549.00. The week we brought the car home it was still bouncing up and down and we contacted the dealer again and was advised they did not find anything wrong. Within 2 weeks of having the vehicle, I was driving and the vehicle was violently bouncing up and down even traveling at a low level. We took the vehicle back and have not been advised now that they see the malfunction light for the suspension on they realize that's the issue. The suggested cost to repair only the rear is $4k. If the front and rear need repairs it over $7k....

WE PURCHASED THE 2013 GL 550 FIVE MONTHS AGO. WHEN WE WERE DRIVING HOME THE VEHICLE SHIFTED ITSELF INTO PARK WHILE IN WAS IN DRIVE. THE VEHICLE ABRUPTLY STOPPED AND VIOLENTLY JERKED THE CAR AND OUR FAMILY WAS INSIDE IN TRAFFIC APPROACHING A FOUR WAY STOP LIGHT. WHEN WE ATTEMPTED TO PUT THE CAR BACK INTO DRIVE AND PULL OFF THE CAR AUTOMATICALLY SHIFTED ITSELF INTO PARK AGAIN WHILE WE WERE DRIVING. THIS HAPPENED IN THE MIDDLE OF TRAFFIC WHILE MAKING A LEFT TURN WITH ONCOMING TRAFFIC AT A LIGHT. POLICE WERE CALLED. CAR WAS TOWED. WE'VE SINCE FOUND THAT THERE WAS A RECALL FOR FAULTY INSTALLATION OF THE EIS FOR THE MODEL YEAR RIGHT BEFORE OURS, 2012. APPARENTLY THE PROBLEM WAS NEVER FIXED AND WAS PASSED ON, BUT MERCEDES BENZ FAILED TO WARN CONSUMERS NOR ISSUE A RECALL. WE ARE GETTING NO HELP WITH REPAIRS EVEN THOUGH THIS IS AN ONGOING SAFETY ISSUES OCCURRING IN SEVERAL OF THEIR CARS. WE'RE ASKING NHTS FOR ASSISTANCE WITH FORCING MERCEDES BENZ TO FIX THIS VERY DANGEROUS AND EXPENSIVE PROBLEM...

WHEN ACTIVATION OF THE SUSPENSION LIFT SYSTEM. COMPRESSOR IS COOLING THEN A MALFUNCTION MESSAGE APPEARS ON THE SCREEN. VEHICLE SHAKES VIOLENTLY IN THE REAR UP AND DOWN AT LOW AND HIGH SPEEDS AND OVER ANY SMALL BUMPS IN THE ROAD. THIS CONCERNS ME FOR THE SAFETY OF OTHER OWNERS WHOM MAY HAVE THE SAME PROBLEM. 2013 MERCEDES BENZ GL 450 IS THE MODEL I OWN CURRENTLY AND IVE BEEN HAVING THIS PROBLEM FOR THE PAST 3 MONTHS AND I'M ALMOST SCARED TO DRIVE IT FOR FEAR OF SOMETHING CATOSTROPHIC HAPPENING. PLEASE LOOK INTO THIS PROBLEM. EVEN WHEN PARK AND ACTIVATING THE SUSPENSION SYSTEM THE ERROR MESSAGE STILL APPEARS.. I HAD A INDEPENDANT MECHANIC SAY ITS THE REAR AIR BAGS AND THE COMPRESSOR THAT HAS TO BE REPLACED BECAUSE OF IT BEING A 4 MATIC MODEL THE AIR LINE FROM THE COMPRESSOR IS NOT SUPPLYING THE REAR SUSPENSION WITH ENOUGH AIR TO LIFT THE VEHICLE THUS CAUSING THE PROBLEM THAT WE HAVE.

2013 MERCEDES ROUGH RUNNING AT IDLE, VARIOUS FAULTS STORED FOR INJECTOR QUANTITY COMPENSATION FOR CYLINDER BALANCING. FAULT CODE P1CWF-85. THE CHECK ENGINE LIGHT EVENTUALLY CAME ON. UPON FURTHER INSPECTION AND DIAGNOSIS FOUND THAT BOTH ENGINE BANK 1 AND 2 CAMSHAFT POSITION SENSORS WERE FULL OF OIL DUE TO FAILED INTERNAL PACKING OF SENSOR. INSPECTED INJECTOR CONNECTORS AND HAD OIL, O2 SENSORS CONNECTOR HAD OIL, POWER TRAIN CONTROL UNIT FULL OF OIL. IF ENOUGH OIL WAS TO FLOW THROUGH THE ELECTRICAL WIRES TO THE CONTROL UNIT AS SUCH THIS INSTANCE OR SENSOR MAY RESULT IN IMMEDIATE CATASTROPHIC FAILURE AND VEHICLES ABILITY TO DRIVE. IF THE VEHICLE IS ON THE HIGHWAY AND STOPS WORKING MAY ENDANGER OCCUPANTS. ALSO NOTED THAT THE FAILED PART IS A MERCEDES BENZ SERVICE BULLETIN FOR PREVIOUS MALES AND MODELS BUT THIS 2013 GL550 IS NOT INCLUDED EVEN THOUGH THE SAME PART NUMBER IS USED IN THE NEW CARS AS THE PREVIOUS VEHICLES WITH THIS MERCEDES BENZ ACKNOWLEDGED ISSUE. ALSO NOTED THAT THE BODY HARNE...
