NHTSA Complaint #10716754 — 2006 PONTIAC GRAND PRIX

R READING SOME OF THE COMPLAINTS THAT HAVE BEEN SUBMITTED, I DON'T KNOW WHERE TO BEGIN OR IF I HAVE ENOUGH CHARACTERS TO EXPRESS MY FRUSTRATION WITH MY 2006 PONTIAC GRAND PRIX GT SUPERCHARGED. MY RECENT ISSUE IS THAT THE CAR KEEPS CUTTING OUT AND STALLING.I TOOK THE CAR TO THE DEALER AND SPENT $110 ON A DIAGNOSTIC AFTER 4 OTHER LOCAL MECHANICS COULD NOT DUPLICATE THE ISSUE OR PINPOINT THE PROBLEM. THE RESULT FROM THE DEALER'S DIAGNOSTIC WAS: P0300 MULTIPLE MISFIRES; NEEDS 3 COILS AND IGNITION MODULE REPLACED $1090 INSTALLED; ALSO HAS A BEARING GOING OUT IN THE SUPER CHARGER AND THERE IS A HARSH 1-2 SHIFT. I JUST SPENT ABOUT $1000 GETTING FUEL PUMP, BACK WHEEL BEARINGS, RIGHT BRAKE HOSE, AND VALVE COVER GASKETS REPLACED. RACK AND PINION HAD TO BE TIGHTENED ALTHOUGH IT WAS REPLACED TWICE LAST YEAR (BAD PART THE FIRST TIME). I HAVE HAD POWER STEERING PUMP REPLACED, WATER PUMP REPLACED, AIR INTAKE TUBE/VALVE REPLACED. PAID DEALER FOR DIAGNOSTIC BECAUSE NO CODES OR INDICATOR LIGHTS WERE ON AND 4 DIFFERENT MECHANICS COULDN'T PINPOINT ISSUE. DEALER STATED THEY HAVE UP-TO-DATE EQUIPMENT AND CODE P0300 CAME UP. CAR INTERMITTENTLY HESITATES TO START. CAR ACTS HESITANT AFTER CAR STARTS AFTER HESITATING TO START. INTERIOR SEATS AND DASHBOARD HAS CRACKED. ABS/TRACTION SEEMS TO BE FAILING, CAR STILL MOVES AFTER APPLYING FOOT ON BREAK...SLIDES A LITTLE, NO IMMEDIATE STOP, EVEN AFTER I HAVE HAD COMPLETE BRAKE WORK PERFORMED (WHEEL BEARINGS, PADS, ROTORS, HUBS, ETC.). SUPERCHARGE SWITCH HAS BEEN REPLACED AND ELBOW TUBE OFF THE MOTOR BLOCK (THINK THAT IS CORRECT, IT'S AN L-SHAPED SMALL TUBE). A LOT OF REPAIRS HAVE BEEN MADE. THE CAR RUNS SMOOTHLY WHEN NECESSARY REPAIRS ARE MADE. HATE TO GET RID OF THE CAR WITH ALL THE MONEY AND CARE THAT HAS BEEN PLACED INTO THE CAR. I AM NOT IN A POSTION TO PURCHASE A NEW VEHICLE BUT WITH THE MILES I DON'T WANT TO PUT EXTENSIVE $. GM WON'T ASSIST.
