ON SEPTEMBER 6 2017 MY MERCEDES CLUSTER PANAL (ODEMETER) STOPPED WORKING WHILE DRIVING. WHICH THEN I MADE AN APPOINTMENT WITH THE DEALERSHIP AND THEY REPLACED THE ODOMETER WHICH THEN FAILED AGAIN HOURS AFTER PICKING UP THE CAR. AFTER REPLACING IT 3 TIMES UNDER WARRANTY I'M STILL EXPERIENCING THE SAME ISSUE. I CONTACTED MERCEDES CUSTOMER SERVICE AND THEY AIN'T ADDRESSING THE ISSUE PROPERLY AND HAS STOPPED CALLING ME BACK REGARDING THIS MATTER. I HAVE BEEN OUT OF A CAR SINCE SEPTEMBER 6,2017 TILL TODAY WITH NO LOANER VEHICLE FROM MERCEDES. I WAS FORCED TO RENT A CAR UNDER MY OWN EXPENSE WHILE STILL MAKING THE LEASE PAYMENTS ON THE MERCEDES THAT IS NOT SAFE TO DRIVE SINCE I'M NOT ABLE TO KNOW SPEED, GAS, GEAR I'M IN ETC..

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2016 Mercedes-benz Gl-class verdict →
