2008 Pontiac Grand Prix Brakes Problems

FIRST TIME I NOTICED A PROBLEM I WAS MAKING A SHARP RIGHT TURN INTO A PARKING SPOT DRIVING ROUGHLY 5 MPH OR LESS. WHEN I PUSHED ON THE BRAKE IT JUST PULSATED MUCH LIKE THE ABS TAKING OVER BUT THE CAR WOULD NOT STOP! I ALMOST HIT THE CAR IN FRONT OF MY PARKING SPOT. I HAD IT IN A SHOP FOR OTHER REPAIRS AND MENTIONED THIS BUT SINCE AT THE TIME IT WAS INTERMITTENT THEY BLEW IT OFF AS I MUST HAVE BEEN BRAKING ON ICE. ONCE IT STARTED TO WARM UP IN THE SPRING AND IN THE SUMMER IT STARTED HAPPENING MORE AND MORE BUT ONLY WHEN TURNING. I HAD A FEW CLOSE CALLS WHERE I HAD ALMOST CRASHED. WHEN IT HAPPENS NOW THE DASH WILL DISPLAY SERVICE ABS AND SERVICE TRACTION CONTROL SYSTEM. IT DID NOT DISPLAY THAT BACK WHEN IT WAS INTERMITTENT. I HAVE SINCE PULLED THE ABS FUSE AND WHILE THE SAME SERVICE LIGHTS COME ON AT LEAST I HAVE BRAKES! I THINK IT WAS 5 OR SO MONTHS EARLIER THAT I HAD MY FRONT RIGHT WHEEL BEARING REPLACED BY A PONTIAC DEALER AND I HEAR THAT BECAUSE THE WHEEL BEARING AND SPEED SENSOR ARE ONE OF THE SAME THAT I MAY NEED THAT REPLACED AGAIN. THIS IS NOT SAFE AND THE MORE PEOPLE I TALK TO THEY HAVE HEARD OR EXPERIENCED THIS AS A COMMON ISSUE. *TR

WHILE LEAVING MY PARKING SPACE, TAPPED THE BRAKE PEDAL, BRAKE PEDAL SEEMED TO RESIST BEING APPLIED. WHILE STILL IN THE PARKING LOT, TRYING TO STOP, NOTICED THE BRAKES PULSATING AS IF THE ABS SYSTEM WAS TRYING TO KICK ON. WITH SIMILAR RESISTANCE AS BEFORE AS PULSATING CEASED. HAPPENS DAILY NOW. TODAY 9/4/12 THE ABS & TRACTION CONTROL LIGHTS BOTH CAME ON SHOWING BOTH NEED SERVICED. EACH TIME THIS HAS OCCURRED, THE PAVEMENT HAS BEEN DRY WITHOUT ANY APPARENT GRAVEL AT THE LOCATIONS. *TR

BRAKELINE CONNECTION UNDER VEHICLE (IN FRONT OF WHERE DRIVER SITS) COULD BECOME CRACKED OR BROKEN IF KNOCKED BY ROAD DEBRIS, OR BUMPS IN THE ROAD. I NOTICED THIS ON MY 2008 GRAND PRIX GXP, SO NOT SURE IF THIS MODEL SITS LOWER TO THE GROUND THAN OTHER GRAND PRIX MODELS. WATCHING RESERVOIR FLUID LEVEL TO DETERMINE HOW MUCH IS LOST OVER A MONTH. I DISCOVERED AFTER NOTICING A BURNT FLUID SMELL IN THE CABIN AFTER 16 MAR 2012. PARTICULARLY STRONG AFTER HARD BRAKE SITUATION I WAS TOLD BY LOCAL DEALER THAT THERE WAS NO WARRENTY ON THIS VEHICLE, AND THAT THE PARTS MAY NOT BE AVAILABLE ANYMORE.

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

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
