CONTINENTAL CONTISPORTCONTACT SSR TIRES SIDE WALL RIP/TEAR (MERCEDES BENZ), THIS IS THE FORTH REPLACED TIRES, COMPLAINED SEVERAL TIMES AND FALLS ON DEATHS EARS. MY CONCERN IF A MAJOR CRASH DO TO THE TIRES THEN WHO IS AT FAULT. REPLACING IT SEVERAL TIMES IS NOT THE ANSWER. TAKING THESE TIRES OFF THE ROAD WILL SAVES LIVES. CAR ONLY HAS 6000 MILES ON IT.

I WILL HAVE TO RETURN THE CAR TO THE DEALER FOR REPAIR. THE TRANSMISSION HAS A VERY HARD SHIFT WHEN I ACCELERATE MORE THAN MODERATE; THE HARD SHIFT CAUSES THE VEHICLE TO PAUSE AND JAR /JERK ABRUPTLY THAT ALMOST SEEMS LIKE YOU HIT SOMETHING. I HAD REPORTED THE ISSUE WITHIN 7 DAYS OF PURCHASE AND I WAS TOLD AMGS HAVE HARD SHIFTS. WHEN I INSISTED THERE WAS AN ISSUE A SECOND TIME IN MARCH 2019; THE ISSUE WAS ADDRESSED AND I WAS TOLD IT WAS THE COMPUTER SOFTWARE THAT REQUIRED AN UPDATE; THE UPDATE TEMPORARILY CORRECTED THE PROBLEM FOR APPROX 1 MONTH. THE VEHICLE HAS BEEN OUT OF SERVICE FOR APPROXIMATELY 13 DAYS SINCE PURCHASED 9 MONTHS AGO IN JULY 2018.

I HAVE OWNED THE CAR FOR ABOUT 14 MONTHS AND DRIVEN JUST OVER 10,000 MILES DURING THAT TIME. I HAVE NOW HAD MY FIFTH FLAT OR DAMAGED FRONT TIRE SINCE OWNERSHIP OCCURRING ON BOTH DRIVER SIDE AND PASSENGER SIDE. THE DEALER REPLACES THE TIRE, WITH THE OEM REPLACEMENT, FIRST AT MY COST OF AROUND $400 EACH AND THEN EACH SUBSEQUENT TIME FOR $35 UNDER THE INCLUDED ROAD HAZARD WARRANTY. I HAVE CONTACTED THE DEALER AND MBUSA ABOUT THIS REOCCURING ISSUE WHICH THEY STATE IS NOT UNDER RECALL AND IS AN ISSUE WITH THE TIRE MANUFACTURER. HOWEVER, I FAIL TO SEE HOW THEY ARE NOT RESPONSIBLE BECAUSE THEY CHOSE THE OEM TIRE SUPPLIER. IN EVERY CASE EXCEPT ONE, THE TIRE ISSUE WAS CAUSED BY A RELATIVELY SHALLOW POT HOLE OR PAVEMENT DEFECT. THE ONE EXCEPTION WAS WHEN I CAME IN CONTACT WITH A MORE SUBSTANTIAL POT HOLE AT NIGHT (I DIDN'T SEE IT) AND THE TIRE BLEW OUT COMPLETELY AND I HAD TO ABANDON THE CAR OVERNIGHT UNTIL THE DEALER COULD TOW IT THE NEXT DAY. ONE TIME, THE CAR WAS TRAVELING AT HIGHWAY SPEEDS, BUT OTHER TIMES IT WAS ON BACK ROADS AT SPEEDS OF NO MORE THAN 35-40 MPH. THE TIRES ARE RUN FLAT TIRES AND THE CAR HAS NO SPARE SO I AM RELUCTANT TO DRIVE AT NIGHT AND DEFINITELY CANNOT TAKE ON ANY TRIPS FOR FEAR OF GETTING STRANDED.
