NHTSA Complaint #10609264 — 2013 CHEVROLET IMPALA

I PURCHASED A 2013 IMPALA IN NOVEMBER WITH 19,000 MILES ON IT. I NOTICED A BANG IN THE FRONT END WHEN BACKING OUT OF DRIVEWAY CUTTING TO THE RIGHT OR LEFT. THE DRIVERS TIRE IS WEARING UNEVEN BECAUSE THE ALIGNMENT IS OFF "BUT ONLY SLIGHTLY AND WITHIN SPECS". STEERING WHEEL SHAKES AT 45-50 MPH WITHOUT PULLING. GO OVER A BUMP AND FEEL A VIBRATION IN THE FLOOR UNDER MY FEET! IT HAS BEEN IN SEVERAL TIMES AND THEY HAVE DONE THE FOLLOWING: 1. TIGHTEN MOTOR MOUNT 2. HAD IT HALF A DAY TO REPLACE A BROKEN MOTOR MOUNT (SAME ONE THEY TIGHTENED TWO WEEKS EARLIER) 3. HAD IT ALL DAY TO "LISTEN FOR THE NOISE", HEARD IT AND ORDERED A STRUT SPACER 4. HAD IT HALF A DAY TO REPLACE STRUT SPACER, DID NOT STOP THE NOISE THEY HAVE HEARD THE NOISE 3 TIMES AND MADE SEVERAL ATTEMPTS TO CORRECT BUT WAS NOT SUCCESSFUL. I SUGGESTED THE RACK AND PINION BUT WAS TOLD GM WILL NOT PAY THEM TO EXPLORE MY FRONT END. SHOP SAYS WITHOUT HEARING THE NOISE ALL THE TIME WE WILL HAVE TO WAIT FOR A "CATASTROPHIC EVENT TO OCCUR". *TR
