Open the full vehicle complaint log (all categories)OUR 2004 PONTIAC GRAND PRIX HAS HAD TWO FAILURES OF THE HEATER MOTOR IN THREE YEARS. IN BOTH CASES NOXIOUS FUMES AND SMOKE CAME FROM THE DASHBOARD. I CONSIDER THIS A SAFETY ISSUE BECAUSE THE SIGHT OF SMOKE COMING FROM THE DASHBOARD WHILE ON A BUSY INTERSTATE (WE WERE) CAN RESULT IN GREAT ANXIETY. I'M AN ELECTRICAL ENGINEER AND MY MECHANIC LET ME SEE THE PARTS. THE SMOKE CAME FROM A RESISTOR THAT IS PART OF THE SPEED CONTROL FOR THE MOTOR. IT'S A VERY POOR DESIGN, WITH HEAT FINS TO DISSIPATE THE HEAT INTO THE HEATER/AC AIR FLOW. IF THE MOTOR STARTS TO DRAG, CURRENT GOES UP AND AIRFLOW GOES DOWN, WITH THE RESULT THAT THE RESISTOR HEATS UP TO THE POINT WHERE IT PUTS SMOKE INTO THE AIR STREAM. I CONSIDER THIS EXTREMELY POOR DESIGN, AND A POTENTIAL FIRE HAZARD. I'VE WRITTEN TO THE MANUFACTURER AND SUGGESTED A NEW DESIGN (I HATE HAVING TO RE-DESIGN THINGS DONE BY AMATEURS!). *TR
LEFT FRONT PASSENGER WINDOW WENT DOWN WITH OUT ANY WARNING AND DID NOT COME BACK UP, ANOTHER PIECE OF CRAP AND ANOTHER IDIOTIC PIECE OF ENGINEERING BY THE PONTIAC ENGINEERING DEPT. BROKEN CABLE ON THE POWER WINDOW SYSTEM LEADING TO TOTAL FAILURE AND HAVING TO REPLACE THE WHOLE ASSEMBLY. *TR
HEADS UP DISPLAY ON 2004 GRAND PRIX FAILED DUE TO CONTROL SPRING BECOMING FREE DUE TO PREMATURE PART FAILURE OF THE PLASTIC ARM. THIS LEAVE A BLACKISH/GRAYISH SQUARE ON THE WINDSHIELD WHERE CREATES A DRIVING NUISANCE- WHERE THE HUD SHOULD BE. THIS PART FAILURE IS MENTIONED NUMEROUS TIMES ON THE INTERNET, THUS LEAVING THE OWNERS WITH A $600-700 REPAIR IN WHICH THERE ISN'T A NEW PART BUT INSTEAD A REBUILT ONE PUT IN. *TR
POWER WINDOWS GO DOWN BY THEM SHELF'S AND WILL NOT COME BACK UP, / FAILURE IN THE POWER WINDOW MOTOR MECHANISM. *TR
THE BLOWER FOR MY HEATER WILL NOT SHUT OFF EVEN THOUGH THE KEYS ARE OUT OF THE IGNITION AND THE CAR IS SHUT OFF. *TR
WHEN I TURN MY VEHICLE OFF THE HEATER/BLOWER CONTINUES TO RUN. I DID SOME RESEARCH ON THIS AND IT SEEMS THAT GRAND PRIX'S ARE NOTORIOUS FOR THIS. I BELIEVE THIS IS A KNOWN ISSUE WITH THE VEHICLE AND I SHOULD NOT HAVE TO PAY FOR IT, IT SHOULD BE A RECALL. *TR
HEADS-UP DISPLAY SHOWS DOUBLE IMAGE AND IS BLURRY-- REPLACEMENT WINDSHIELD AT CUSTOMER EXPENSE CORRECTED PROBLEM.*AK
REAR DEFOGGER GRIDS INOPERATIVE. DEALER FOUND AND REPAIRED MINUTE CRACKS IN HEATER ELEMENT ON TWO OCCASIONS. NEW REAR WINDOW TO BE INSTALLED SINCE PROBLEM CANNOT BE REPAIRED
NOT ALL GRIDS IN REAR DEFROSTER WORKING. WHEN DEFROSTER IS ON I GET STATIC FEEDBACK INTO THE RADIO. DEALER REPAIRED GRIDS ONCE, BUT PROBLEM CONTIUNED AS SOON AS I PICKED UP THE CAR. DEALER IS TO REPLACE GLASS NEXT WEEK.*AK
