Open the full vehicle complaint log (all categories)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.
RUN FLAT TIRES WENT FLAT ON A POTHOLE THAT WAS NOT EVEN REALIZED ON A SUNDAY WITH NO SERVICE STATION OPEN. EVEN IF THEY WERE, THE TIRE HAS TO BE REPLACED, CANNOT BE REPAIRED. THERE IS NO SPARE TIRE OPTION- WHEN CONTACTED, COMPANY REFUSED " NOT POSSIBLE". THIS IS NOT SAFE AT ALL AND MUST BE ADDRESSED. MUST HAVE SPARE TIRE ESP SINCE RUN FLAT TIRES CANNOT BE REPAIRED AND ARE NOT IN STOCK AT MOST SERVICE STATIONS
CAR COMES WITH 19"RIMS AND RUN FLAT TIRES (BRIDGESTONE DRIVE GUARD). SINCE LEASOING THE CAR IN NOVEMBER 2018, I HAVE RECEIVED 8 FLAT TIRES ALL FROM "POTHOLES" THAT RIPPED THE SIDE WALL. CONSUMER AFFAIRS SAYS THIS TIRE SHOULD NOT BE ON THIS CAR IN CERTAIN STATES IN THIS CASE NEW YORK. INFINITI DEALERS DO NOT OFFER AN OPTION AND THE UNSUSPECTING CONSUMER IS LEFT WITH A HAZARDOUS SITUATION. YOUR EYES CAN LEAVE THE ROAD AS YOU SEARCH FOR EVEN SMALL POTHOLES TO AVOID. WHEN THE TIRE DOES GO FLAT AND YOU ARE MORE THAN 25-50 MILES AWAY FROM A REPAIR SHOP YOU ARE IN DANGER OF BEING STRANDED. I WAS STRANDED IN A SNOWY WOODED AREA AND HAD TO DRIVE 25 MILES IN TREACHEROUS CONDITIONS WITH A CHILD IN THE CAR JUST TO FIND A REPLACEMENT. THE TIRE SHOULD NOT BE ON A CAR WITH A HEAVY FRONT END PER THE TIRE DEALER AND TIRE REPAIR SHOP. INFINITI KNOWS THIS AND WILL OFFER TO PAY FOR A NEW TIRE, RATHER THAN PUTTING CUSTOMER SAFETY FIRST AND DISCONTINUING THIS TIRE/RIM IN NY STATE. IN SEVERAL INSTANCES THE POT HOLE HIT WAS LESS THAN THE WIDTH OF THE TIRE.
