NHTSA Complaint #10470686 — 2007 CHEVROLET IMPALA

I WILL NOT DRIVE THIS CAR DOWN ANY STEEP GRADE. GOING DOWN CUESTA GRADE AND APPLYING BRAKES, THE STEERING WHEEL SHAKES UNCONTROLLABLY. WE HAD THE CAR CHECKED OUT AT A DEALER AND THEY SAID IT WAS PROBABLY THE ROTORS. WE THEN HAD THEM TURNED FRONT AND BACK AND GOT A FRONT END ALIGNMENT. THAT DID NOT CHANGE ANYTHING. WE THEN HAD A FOUR WHEEL ALIGNMENT DONE AND REPLACED THE BRAKES. NO DIFFERENCE. THAT IS WHEN WE WERE TOLD WE NEEDED TO REPLACE OUR TIRES. THE REAR WERE WEARING OUT AT VERY FAST. THEY LASTED UNDER 20K MILES. WE ARE NOW ON OUR THIRD SET. IT'S TOO BAD GM WILL NOT RECALL 2007/2008 IMPALAS. ONLY THE POLICE VERSION.THIS IS NOT RIGHT. OUR REAR SPINDLES AND FRONT UPPER/LOWER CONTROL ARMS SHOULD BE REPLACED AT NO COST TO US. IF NOT WHO WOULD BOTHER BUYING THIS CAR WHEN WE SELL IT? *TR
