NHTSA Complaint #10949625 — 2012 CHEVROLET VOLT

SEE NHTSA COMPLAINT NUMBER 10949504 FEB 3, 2017 THAT REFLECTS A SECOND TIRE IN THE SAME DRIVER FRONT POSITION WHEN IT LOST PRESSURE DUE TO A CRACK IN THE SIDEWALL WHILE SITTING IN THE DRIVEWAY THE MORNING OF FEB 3, 2017. THE PRESSURE HAD DROPPED FROM ABOUT 38 PSI TO 26 PSI OVER ABOUT 2 DAYS IT HAD BEEN PARKED. I GOT IT TO A CORNER GAS STATION ABOUT 1 MILE AWAY WHO WHERE - LOSING ANOTHER 2 PSI WHILE TRAVELING AND THE MECHANIC DETECTED THE SIDEWALL PROBLEM INDICATING IT WAS A TIRE DEFECT AND IT WOULD BE BEST TO TAKE IT TO THE DEALER/SERVICE DEPT. IT WAS RE-PRESSURIZED TO 38PSI AND OTHER TIRE PRESSURES WERE CHECKED (NO PROBLEMS). GOING THE FEW MILES TO THE DEALER, THE TIRE LOST 4-5 PSI PRESSURE. I WAS TOLD BY THE DEALER/SERVICE MANAGER THAT THE TIRE NEEDED REPLACEMENT AND THAT IT WAS SOMETHING I MIGHT HAVE DONE AND NOT A TIRE PROBLEM. THE SIDEWALL DEFECT SEEMS A SAFER DUPLICATE OF THE FIRST TIRE FAILURE (THAT HAPPENED ON THE INTERSTATE DURING SLOW MOVING TRAFFIC AND WITH FOUR ADULTS IN THE CAR - NHTSA COMPLAINT 10706538, 4/19/15). NOTE THAT BOTH TIRE FAILURES THE TWO ON THE DRIVER'S SIDE. TIRE ROTATIONS ARE DONE FRONT/BACK ON THE SAME SIDE, ONSTAR AND I BOTH MONITOR TIRE PRESSURES, TIRES HAVE NOT BEEN DRIVEN UNDER OR OVER-INFLATED, FAILURES HAVE BOTH BEEN IN THE DRIVER FRONT POSITION (HEAVIEST LOAD).
