NHTSA Complaint #10314761 — 2008 CHEVROLET IMPALA

I PURCHASED 2008 CHEVY IMPALA WITH 22000 MILES ON IT AT NORMAN FREDE IN CLEAR LAKE/HOUSTON AREA. AFTER 6MONTHS THEY SUGGESTED TIRE ROTATION WAS NEEDED AND DUE AFTER ROTATION I NOTICED CAR SHAKING BETWEEN 20 TO 30MPH AND ABOVE 65MPH I TOOK IT IN AND IT WAS ALIGNED AND I WAS CHARGED 2MONTHS LATER STILL SHAKING WAS REALIGNED AT NO CHARGE BUT BEFORE THAT I HAD A NAIL IN ONE OF BACK TIRES AND I HAD IT REPAIRED BY A TIRE SHOP AND THEY WERE SHOCKED TO SEE MY 4 TIRES WERE WORN AND THEY SHOWED ME, I WAS SO UPSET I TOOK CAR IN AGAIN AND THEYSAID BECAUSE I HAD 36,000 MILES ON IT WAS THE REASON. WELL I TOOK IT IN AGAIN AND THEY TOLD ME STRUT NEEDED TO BE REPAIRED THAT'S WHY MY TIRES WERE ALL WORN AND WANTED TO CHARGE ME $150 TO REPAIR STRUT AND $400 PLUS FOR TIRES AND I SAID "NO" WHY SHOULD I HAVE TO PAY I HADN'T EVEN HAD THE CAR FOR A YEAR AND THIS WAS HAPPENING, I WAS UPSET AND LEFT BUT BEFORE I LEFT THEY REALIGNED IT AGAIN AND IN MY SERVICE TICKET THEY DID NOT EVEN MENTION THE STRUT REPAIR. I TRIED TO CONTACT THE SERVICE MANAGER BY EMAIL AND THE GENERAL MANAGER, I RETURNED THE SERV MGR CALL TWICE BUT KEPT MISSING HER AND THE GEN MGR NEVER CALLED OR EMAILED ME. I FEEL THAT THIS IS A CERTIFIED CAR AND I SHOULD NOT HAVE TO DRIVE LIKE THIS OR PAY FOR ANY REPAIRS. PLEASE WHAT CAN I DO. *TR
