NHTSA Complaint #10451851 — 2007 CHEVROLET IMPALA

DURING THE COURSE OF OWNING THIS IMPALA SINCE IT WAS NEW, IT HAS HAD 12 REPLACEMENT TIRES INSTALLED IN ORDER TO CORRECT A VIBRATION PROBLEM, WHICH IS FELT AT OR AROUND 55 MPH. IT HAS TAKEN APPROXIMATELY 10,000 MILES FOR EACH OF THE TIRES TO WEAR UNEVENLY. EACH TIME A TIRE WAS REPLACED, I WAS GIVEN AN EXPLANATION THAT THE DEFECTIVE TIRE WAS NO LONGER ROUND (EGG SHAPED) AND WOULD NOT PROPERLY BALANCE. A MAJORITY OF THE DEFECTIVE TIRES WERE FROM THE REAR OF THE IMPALA. THE LAST REPLACEMENT TIRES WERE INSTALLED ON 06-28-10 WHEN THE VEHICLE HAD 26,264 MILES ON IT. DURING THE DOZENS OF VISITS TO MULTIPLE CHEVROLET SERVICE DEPTS, NO MECHANICAL SUSPENSION PARTS WERE REPLACED. I'VE BEEN IN CONTACT WITH THE GENERAL MOTORS EXECUTIVE CUSTOMER SERVICE OFFICE (GMECSO) FOR YEARS AND HAVE DEALT WITH MULTIPLE REPRESENTATIVES. THE IMPALA AGAIN HAS A VIBRATION, AND I WOULD LIKE TO GET THE VEHICLE SERVICED. GMECSO INFORMED ME THAT THEY WANTED ME TO TAKE THE IMPALA TO A DIFFERENT CHEVROLET SERVICE DEPARTMENT IF I NEEDED TO GET THE CAR LOOKED AT FOR ISSUES REGARDING THE TIRES. SINCE 02-05-12, I HAVE MADE 5 PHONE CALLS TO THE GMECSO AND HAVE YET TO RECEIVE A CALL BACK. *TR
