NHTSA Complaint #10618321 — 2008 CHEVROLET IMPALA

WHILE DRIVING AT HIGHWAY SPEED, NOTICED SOME VIBRATION FROM REAR TIRES. CHECKED TIRES WHEN I GOT HOME. REAR TIRES HAVE EXTREME TREAD WEAR ON THE INSIDE EDGE. THIS WEAR IS HIDDEN BECAUSE IT IS ON THE VERY INSIDE EDGES OF THE TIRES, AND YOU DON'T NOTICE WHEN LOOKING AT THE TIRES FROM THE SIDE OF THE CAR. MOST OF THE TIRE YOU CAN SEE LOOKS NORMAL. THE WEAR IS ON THE INNER MOST 5% OF THE TREAD. AND IT IS EXTREME WEAR, ALL THE WAY THROUGH THE STEEL BELTS. I RESEARCHED AND FOUND A GM SERVICE BULLETIN FOR 2007-8 IMPALA TIRE WEAR AND SUSPENSION PROBLEMS LIKE THIS. BUT THAT BULLETIN ONLY CALLED FOR SERVICE ON MODELS WITH POLICE SUSPENSION IN THE REAR. THE SOLUTION REQUIRED REPLACEMENT SPINDLE ARMS TO BE INSTALLED. CALLED GM AND THEY WILL NOT REPLACE MY CONSUMER SPINDLES. BUT I HAVE THE SAME PROBLEM. THIS TIRE WEAR HAS CAUSED BOW OUTS AND CRASHES IF YOU LOOK AT REPORTS THAT A GOOGLE SEARCH CAN FIND. SEARCH FOR IMPALA SPINDLE AND TIRE WEAR. YOU WILL BE AMAZED AT HOW OBVIOUS THIS DEADLY DEFECT IS. *TR
