We almost got into crash the other day, our 8-year-old kid got our attention that rear seatbelt got very loose and did NOT retract back at all. he almost hit his head. when I asked him if it has been like this he said no, it was tight when I buckled it in. We tried several times to retract it manually with no luck. I checked online and I have seen people complaining about the same thing. we have been lucky we didn't hit the other car then my child will be seriously injured. This is a very serious safety requirement. I hope Mercedes Benz will take this very seriously as well, before others get hurt.

THIS PAST THURSDAY EVENING (DECEMBER 13, 2018) AROUND 10:00 PM, I WAS DRIVING (WITH MY WIFE IN THE PASSENGER SEAT) DOWN A CURVY STRETCH OF ROAD ON SUNSET BOULEVARD IN BEVERLY HILLS, WHEN I SUDDENLY HEARD A LOUD THUMPING SOUND AND IMMEDIATELY FELT VIOLENT VIBRATIONS THROUGH THE STEERING WHEEL. SINCE WE WERE TRAVELING AT A RELATIVELY LOW SPEED OF 30 MPH, I WAS IMMEDIATELY ABLE TO RE-GAIN THE CONTROL OF MY VEHICLE AND WAS ABLE TO PULL OVER SAFELY. ONCE I GOT OUT OF MY VEHICLE, I IMMEDIATELY NOTICED THAT THE FRONT RIGHT WHEEL RIM HAD COMPLETELY BROKEN INTO TWO HALVES. I WAS SHOCKED AND VERY SURPRISED BECAUSE NOTHING COULD HAVE POSSIBLY EXPLAINED WHY THIS WHEEL COMPLETELY BROKE IN THE MANNER THAT IT DID. WE WERE EXTREMELY FORTUNATE THAT THERE WERE NO OTHER VEHICLES AROUND US AT THE TIME THE WHEEL BROKE, OR THAT WE WERE NOT ON THE HIGHWAY TRAVELING AT MUCH HIGHER SPEEDS, OTHERWISE THE RESULTS WOULD HAVE BEEN FATAL WITH EVEN A POSSIBILITY OF SIGNIFICANT INJURY OR EVEN LOSS OF LIFE. A COMPLETE REPORT WITH PICTURES AND CAUSE OF RAPID FRACTURE OF THE RIM AS A COMPLAINT WAS PROVIDED TO MERCEDES DEALERSHIP AND CORPORATE, THEY ARE REFUSING TO ADMIT TO ANY MATERIAL DEFECT AND LIABILITY.

ACCORDING TO THE RECALL NHTSA CAMPAIGN ID NUMBER: 16V899000 AND THE VEHICLE INSPECTION REPORT FROM THE LOCAL MERCEDES DEALERSHIP SHOW AS AN IDENTICAL ISSUE. HOWEVER, MY VEHICLE IS NOT IDENTIFIED AS APART OF THE RECALL. THE RECALL STATES THE ISSUE IS DUE TO THE STEERING CONTROL UNIT NOT BEING SOLDERED PROPERLY. DIFFICULT TO THINK THIS FALLS UNDER NORMAL WEAR AND TEAR. I WILL GET THE REPAIR DONE BEGRUDGINGLY, THOUGH IT WOULD BE NICE IF MERCEDES WOULD HAVE STOOD BEHIND ITS RECALL.
