Consumer Description

WHILE I WAS DRIVING MY INFINITI ON THE HIGHWAY MY SERPENTINE BELT SNAPPED 4 DIFFERENT TIMES WHILE IN MOTION. ALL WITHIN ONE YEAR. INCLUDING ME GETTING MY CAR BACK FROM THE DEALER AND THEM LETTING ME HAVE IT BACK THAT WAY. ALSO, THE TIRES ARE HORRENDOUS, FROM DAY ONE, THEY PULLED THE CAR LEFT OR RIGHT ON THE CAR. ALL THE SETTINGS WERE CORRECT ON THE CAR. I WANTED TO HAVE THE TIRES REPLACED, BY THE MANUFACTURER, AND THAT CAN BE DONE BECAUSE NO IT'S TO LONG AND EVERYONE TOOK TO LONG TO MAKE THINGS HAPPEN. NOT TO MENTION DUNLOP IS IMPOSSIBLE TO GET A HOLD OF.
