2008 PONTIAC GRAND PRIX Complaints

UNDER HARD HIGH SPEED BRAKING THE FRONT BRAKES SHUDDER BADLY CAUSING A SEVERE FRONT END SHIMMY DUE TO WARPED ROTORS MAKING STOPPING DIFFICULT. IF PRESSURE ON PEDAL IS NOT RELEASED THIS COULD CAUSE LOSS OF CONTROL AND A CRASH. IT IS WORSE IF GOING DOWNHILL. THIS IS A VERY COMMON ISSUE ON GM CARS BUILD IN THE LAST 8 YEARS. THERE ARE POSTS ALL OVER THE INTERNET ABOUT THIS. THE PROBLEM IS WITH POORLY MADE BRAKE ROTORS THAT WARP AT UNDER 15,000 MILES OF NORMAL USE. I HAVE HAD THE SAME ISSUE WITH MY WIFE'S 2003 IMPALA. THESE CARS SHOULD BE RECALLED AND THE ROTORS REPLACED WITH PARTS OF ADEQUATE QUALITY. IF YOU CAN GET THE ISSUE ADDRESSED UNDER WARRANTY, THE DEALER WILL ONLY EITHER TURN THE DEFECTIVE ROTORS OR REPLACE THEM WITH THE SAME OEM JUNK. THE ONLY FIX I HAVE FOUND IT TO REPLACE THEM WITH AFTERMARKET ROTORS AND PADS. *TR

I HAVE A 2008 PONTIAC GRAND PRIX, THE AIR BAG SENSOR LIGHT CAME ON, I CHECKED WITH THE DEALER REPAIR SERVICE, THEY SAID IT WOULD BE $1,100 TO FIX IT. I CALLED GM AND THEY DID OFFER TO PAY FOR HALF THE COST TO FIX IT, BUT MY AIR BAGS WERE NOT ABLE TO WORK WITH THE SENSOR OUT. I HAD TO PAY $475 TO HAVE THE SENSOR REPLACED, IT WOULD SEEM THAT IS SOMETHING THAT SHOULD BE COVERED FOR MORE THAN 3 YEARS, BEINGS THE CAR IS 3 YEARS OLD, NEVER BEEN IN AN ACCIDENT, SO AS FAR AS I KNOW, THE AIRBAGS HAVE NEVER BEEN DEPLOYED, SO WHY WOULD I HAVE TO PAY $1,100 FOR THAT? THAT IS A SAFETY ISSUE, AND IF I WOULD HAVE BEEN IN AN ACCIDENT, THE AIRBAGS WOULD NOT HAVE WORKED. *TR

2008 GRAND PRIX GXP FRONT WHEEL CRACKED, LOSING AIR WITH 24K MILES. THE WEEK BEFORE IT WAS BRAKE PADS AND ROTORS. TOTAL OUT OF POCKET EXPENSES 1,200.00 IN TWO WEEKS. I FIND THIS ABSOLUTELY UNACCEPTABLE FOR A CAR WITH BUMPER TO BUMPER COVERAGE. JUST EXACTLY WHAT DO THEY COVER? LAST I CHECKED MY WHEELS WERE BETWEEN MY BUMPERS, AND IF GM CAN'T BUILD A CAR ROAD WORTHY OF A MICHIGAN WINTER THEY SHOULD NOT BE ALLOWED TO SELL THEM HERE. THIS WOULD BE ALOT EASIER TO SWALLOW IF IT WERE A USED CAR, BUT NEW WITH 24K MILES IS ABSURD! *TR

P-0411 CODE; AIR CONTROL VALVE SOLENOID. MY CHECK ENGINE LIGHT KEPT GOING ON AND THEN WOULD GO OFF. THIS PROCESS REPEATED A FEW TIMES. BOUGHT NEW GAS CAP A FEW TIMES. FINALLY, LIGHT CAME ON AND WOULD NOT GO OFF. TOOK IT TO DEALER WHO TOLD ME IT WAS THE AIR CONTROL VALVE SOLENOID AND IT WAS NOT COVERED UNDER WARRANTY. AFTER LOOKING INTO THIS PROBLEM ONLINE, IT SEEMS THAT THIS IS NOT A NEW PROBLEM WITH THESE CARS. HTTP://AUTOFORUM.CLASSIFIEDS1000.COM/PONTIAC-GRAND_PRIX/SECONDARY_AIR_PUMP HAS SOME LISTINGS. IF YOU SEARCH SECONDARY AIR PUMP; PONTIAC GRAND PRIX CARS - YOU GET MULTIPLE HITS. *TR
