THE REAR SUSPENSION BEGAN TO PRODUCE A HISSING NOISE UPON PARKING. THE NEXT TIME WHILE DRIVING A LOUD RELEASE OF AIR WAS HEARD COMING FROM THE REAR PASSENGER SIDE AND THE REAR END OF THE CAR SLAMMED TO THE GROUND. NOW I HAVE TO HAVE THE REAR SUSPENSION REPLACED. THIS SUDDEN FAILURE AT HIGHWAY SPEEDS, ESPECIALLY IN UNFAVORABLE WEATHER CONDITIONS, COULD RESULT IN A SERIOUS ACCIDENT. REPORTS OF PROBLEMS WITH THE AIRMATIC SYSTEM ARE ABUNDANT AND NOT JUST ISOLATED TO MY AND YEAR OF CAR. IN FACT MB IS CURRENTLY IN A CLASS ACTION LITIGATION REGARDING THE AIRMATIC SUSPENSION IN THEIR GL LINE OF CARS. I BELIEVE THE PROBLEM TO BE SYSTEMIC AND SHOULD BE RESOLVED BY MB TO HELP ASSURE THE SAFETY OF THOSE THAT DRIVE THEIR VEHICLES. *TR

AFTER REPLACING THE LEFT SIDE SUSPENSION AIRBAG THE DAY BEFORE, I NOTICED MY CAR LEANING TO THE RIGHT SIDE AS I GOT INTO IT AFTER USING IT ONCE AFTER BEING REPAIRED. NO WARNING INDICATOR CAME ON WHEN I STARTED THE CAR. I WAS CONCERNED MAKING TURNS IN THIS SITUATION BUT MANAGED TO MAKE IT HOME. I BROUGHT THE CAR IN FOR SERVICE BECAUSE IT WAS OBVIOUSLY UNSAFE TO DRIVE. AFTER REPLACING THE SUSPENSION AIR COMPRESSOR 3 MONTHS EARLIER, THE LEFT SIDE AIR BAG THE DAY BEFORE, I WAS TOLD THAT THE RIGHT SIDE SUSPENSION AIR BAG HAD FAILED. MERCEDES WILL NOT COVER THIS REPAIR AND WILL NOT RECALL THIS KNOWN CONDITION WITHOUT BEING FORCED. THEY SHOULD BE FORCED SINCE MANY PEOPLE ARE HAVING THIS PROBLEM. I HAVE HAD A PROBLEM WITH THIS SUSPENSION SYSTEM 3 TIMES. *TR

WHILE DRIVING DOWN THE HIGHWAY, A DASHBOARD INDICATOR DISPLAYED "CAR TOO LOW". WE PULLED OVER AND THE REAR END OF THE CAR WAS SITTING AS LOW AS POSSIBLE. IT WAS CLEAR THAT THERE WAS A PROBLEM WITH THE AIR BAG SUPPORTED SUSPENSION. ON RESTARTING, THE CAR ROSE AND WE WERE ABLE TO MAKE IT TO OUR DESTINATION. THE CAR THEN, WITH INCREASING FREQUENCY HAD THIS PROBLEM. I BROUGHT IT IN FOR SERVICE AND THE AIR COMPRESSOR THAT INFLATES THE REAR SUSPENSION AIR BAGS WAS REPLACED. THIS PROBLEM OCCURRED WITH NO WARNING AND AT HIGHWAY SPEEDS WITH 5 PERSONS IN THE CAR CREATING AN IMMENSE SAFETY RISK. MANY OTHERS HAVE REPORTED THE SAME ISSUE WITH THIS AND RELATED CARS FOR THIS AND NEARBY MODEL YEARS. LIKE THEM, I WONDER WHY THERE IS NO RECALL. MERCEDES BENZ WILL NOT REPLACE THESE DEFECTIVE PARTS WILLINGLY AND THERE ARE MANY OF THESE CARS DRIVING DOWN OUR HIGHWAYS. *TR

I HAD TO TAKE THE VEHICLE TO THE SHOP FOR REPAIRS AT LEAST EVERY 3-5 MONTHS SINCE THE DAY I BOUGHT IT, WHICH WAS IN 2010. NEARLY ALL OF THE REPAIRS HAVE BEEN UNDER WARRANTY, IT ONLY HAS LESS THAN 75, 000M. IN SEPTEMBER OF THIS YEAR WHILE I WAS DRIVING HOME FROM WORK WHEN THE CAR STARTED STALLING JERKING AND SHOUT OFF. THE ENGINE LIGHT, ESP LIGHT AND THE BREAK LIGHT CAME ON. IT IMMEDIATELY RESTARTED, THE ENGINE LIGHT STAYED ON, WHILE THE ESP AND BREAK LIGHT WENT OFF. THIS WAS A VERY FRIGHTEN EXPERIENCE, HOPING I WON'T BE HIT FROM BEHIND. I MADE IT TO THE DEALER SHIP. THE CAR WAS IN THE SHOP FOR 3WKS WHEN I WAS TOLD THAT IT NEEDED TO HAVE A TUNE UP BEFORE ANY OTHER REPAIRS COULD BE DONE, HOW THIS RELATED TO THE VEHICLE JUST STOPPING IN MID DRIVE, IS ODD.TO SAY THE LEAST. 2 DAYS AFTER GETTING THE TUNE UP, IT IS STILL IN THE SHOP BECAUSE THE ENGINE LIGHT IS STILL COMING ON. I'M FEELING UNCOMFORTABLE ABOUT GETTING BEHIND THE WHEELS AGAIN IN THIS VEHICLE. I EXPECTED MORE OUT OF A MERCEDES BENZ WITH LESS THAN 100,000MILES *TR
