2007 Chevrolet Impala suspension problems

“COMPLAINT: REAR WHEELS LINKAGE WAS DESIGNED SO THAT THE "CAMBER" CANNOT BE ADJUSTED. THE REAR TIRES WEAR AGRESSFULLY ON THE INBOARD EDGES TO A POINT THAT THEY ARE BALD WHILE THE OUTSIDE, WHICH IS VISIBLE, APPEARS TO BE GOOD. THE REAR TIRES BECOME UNSAFE, WITH A WEAR RATE THAT ONLY LAST ABOUT 15,000 MILES. I AM ON MY 5TH SET OF TIRES WITH THE CAR MILEAGE AT 66,000. GM WAS AWARE OF THIS CONDITION IN 2008, BUT THEY ISSUED A TSB (08032A) TO CORRECT ONLY "POLICE CARS" AND DID NOT REPAIR OR LET OTHER PRIVATE CUSTOMERS KNOW ABOUT THIS. MY CAR SERIAL NUMBER IS LISTED UNDER THE ONES ON THE TSB. THIS CONDITION ALSO CREATES A PROBLEM WHEN OPERATING THE CAR IN WET AND SLIPPERY ROADS, SINCE THE REAR TRACKING IS NOT THE SAME AS THE FRONT TIRES. THE CAR TENDS TO WHIP FROM SIDE TO SIDE, AN OPERATORS CAN LOOSE CONTROL. THE PARTS USED BY GM ARE THE SAME AS ON POLICE VEHICLES AS PERSONAL CARS. THEY CLAIMED A PROBLEM, BUT FOR SOME REASON DENY ANY ISSUES ON A PERSONAL CAR! GM DEALERS REFUSE TO EVEN SPLIT THE COST, AND GM WILL NOT CORRECT MY ISSUE.”

“TL* THE CONTACT OWNS A 2007 CHEVROLET IMPALA. WHILE DRIVING AT APPROXIMATELY 55 MPH, THE VEHICLE VEERED OFF THE ROAD INDEPENDENTLY. THE VEHICLE WAS DIAGNOSED BY BOTH THE DEALER AND AN INDEPENDENT MECHANIC AND THEY BOTH CONFIRMED THAT THE REAR AXLE WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 20,000. THE VIN WAS UNAVAILABLE.”

“BOUGHT 2007 IMPALA NEW. HAVE REPLACED REAR TIRES 6 TIMES DUE TO CAMBER ISSUE. IMPALA IS DESIGNED WITH NO ADJUSTMENT FOR CAMBER ON THE REAR SUSPENSION. TIRES WEAR ON THE INSIDE AT A FAST RATE. NOTHING IN THE TRUNK TO CAUSE WEIGHT ISSUES, STANDARD HIGHWAY DRIVING ON A DAILY BASIS. TIRE SOUND IS HORRIBLE AND INCREASES WITH SPEED. FIRST SET OF TIRES REPLACED AT 9,000 MILES. GM RECALLED POLICE MODELS OF THE IMPALA TO FIX THE ISSUE, BUT NOT IMPALAS THAT WEREN'T POLICE MODELS. SO GM KNOWS THERE IS AN ISSUE WITH THE REAR SUSPENSION CAUSING EXCESSIVE TIRE WEAR BUT WON'T PERFORM A RECALL. MY WIFE WOULDN'T EVEN DRIVE THE CAR BECAUSE SHE WAS AFRAID TIRES WOULD BLOW OUT ON THE HIGHWAY. 6 SETS OF TIRES ON A VEHICLE WITH 90,000 MILES IS ABSURD. I FINALLY HAD TO HAVE ANOTHER SHOP INSTALL AFTERMARKET CAMBER ADJUSTING BOLTS AND GET AN ALIGNMENT TO FIX THE ISSUE. SHOP I DEALT WITH SAYS THEY'VE BEEN PERFORMING THIS REPAIR ON IMPALA'S SINCE MID 2007. $20 FOR THE BOLT KIT AND $80 FOR THE ALIGNMENT. $100 TO FIX AN ISSUE (NOT INCLUDING TIRE REPLACEMENT COSTS) AND GM WON'T OWN UP TO IT. THIS IS A BASIC DESIGN FLAW THAT GM HAS BEEN AWARE OF, WITH NO ACTION BEING TAKEN ON THERE PART. *TR”

“IN NOVEMBER OF 2013 I NOTICED WEIRD TIRE WEAR ON MY 07 IMPALA LT (REAR).. THOUGHT IT WAS DUE TO LOW GRADE TIRES SO I PURCHASED A TWO BETTER TIRE FOR THE REAR.. MARCH 16 2014 I RECEIVED A FLAT WHILE PARKED... ATTEMPTED TO CHANGE AND INSIDE TIRE WEAR FOUR MONTHS BRAND NEW TIRES DESTROYED. SO I RESEARCHED WHY THIS WOULD HAPPEN AND FOUND OUT THAT GM HAD CLASS ACTION LAWSUIT AGAINST THEM FOR KNOW ABOUT THIS AND ONLY RECALLING LAW ENFORCEMENT ISSUED IMPALA'S.I PURCHASED THE CAR 2010 AND NOVEMBER 2013 IS WHEN I FIRST SEEN PROBLEM. *TR”

“EXCESSIVE WEAR ON INSIDE EDGES OF REAR TIRES I'M JUST FORTUNATE I CAUGHT THE WEAR EARLY . SO I BROUGHT IT TO MY LOCAL CHEVY DEALER FOR A 4 WHEEL ALIGNMENT. I WAS TOLD THAT BOTH REAR SPINDLE RODS NEEDED REPLACING TO THE TUNE OF $700.00. THE SERVICE DEPT. TOLD ME THEY COULD NOT GET ENOUGH ADJUSTMENT IN THE CURRENT SPINDLE RODS TO BRING THE ALIGNMENT INTO SPEC. AND THERE IS AN UPDATED PART TO REPLACE THEM. GM HAS KNOWN ABOUT THIS PROBLEM SINCE 2009 AND IT EFFECTS BOTH 2007 AND 2008 CHEVY IMPALAS. THEY DID A RECALL ON 07 AND 08 POLICE VERSIONS OF THE IMPALA BUT NOT ON THE CIVILIAN VERSION. THE NHTSB NEEDS TO TAKE A HARD LOOK AT THIS DESIGN PROBLEM BEFORE SOMEONE IS HURT OR KILLED DUE TO A BLOW OUT. *TR”
