I WAS DRIVING DOWN THE ROAD AND ALL OF A SUDDEN MY CAR LOST POWER AND SAID "REDUCED ENGINE POWER" I WAS PRESSING THE GAS GOING 55 MPH AND IT SUDDENLY LOST ALL RPMS AND SPEED DROPPED. I WAS ALMOST REAR ENDED BY ANOTHER VEHICLE TRAVELING BEHIND ME. I WAS VERY UPSET ON THE SIDE OF THE ROAD WITH MY SON. I WAS TOLD ABOUT MANY OTHERS WHO HAVE HAD THIS PROBLEM WITH PONTIACS. WHAT IS BEING DONE ABOUT THIS? AND IF NOTHING WHY? MY SON AND I WERE VERY LUCKY WE WEREN'T I'M AN ACCIDENT. WANT ANSWERS AND WHY THERE ISN'T A RECALL GETTING THESE CARS FIXED. IT IS VERY UNSAFE.

THE CAR WAS ABOUT TO ENTER THE MASS PIKE WHEN ALL FORWARD MOTION STOPPED. THE TRANSMISSION WAS IN 'DRIVE' BUT IT ACTED AS THOUGH IT HAD SLIPPED INTO NEUTRAL. THE CAR WAS DEAD IN THE MIDDLE OF THE ROAD AND THERE WERE A NUMBER A NEAR MISS COLLISIONS BEFORE THE EMERGENCY VEHICLE ARRIVED. THE CAR IS NOW AT A GM DEALERSHIP AWAITING A TRANSMISSION REBUILD. WE BOUGHT THIS CAR NEW AND HAVE HAD A NUMBER OF TRANSMISSION ISSUES STARTING AT 12,456 MILES. WITHIN THE FIRST YEAR OF OWNERSHIP WE REPORTED A 'CLUNKING' NOISE TO THE DEALERSHIP - THEY SAID THEY COULD NOT RECREATE THE PROBLEM. WE HAD ADDITIONAL ISSUES WHERE THE CAR WOULD 1) NOT MOVE WHEN STARTING FROM A TRAFFIC LIGHT OR 2) WOULD ACT AS THOUGH IT WAS IN NEUTRAL WHEN COASTING AND THEN 'BANG' INTO GEAR SEVERAL SECONDS AFTER STEPPING ON THE GAS PEDAL. THESE ISSUES WERE REPORTED TO THE DEALER AT 33657, 45381, 51284, 56446, 61543 AND 72552 MILES. IN EACH CASE, EXCEPT FOR THE ONE AT 56446 MILES THE DEALER SAID THEY COULD NOT REPLICATE THE ISSUE - BUT THEY CHARGED FOR THE TIME. AT 56446 MILES WE TRIED ANOTHER DEALERSHIP AND THEY SPENT OVER AN HOUR TESTING THE CAR. FINALLY, THEY DID EXPERIENCE THE PROBLEM. THEY REPLACED SEVERAL TRANSMISSION PARTS BUT WE EXPERIENCED A SHUDDERING PROBLEM LESS THAN A YEAR LATER. THEY DETECTED A POSSIBLE TORQUE CONVERTER PROBLEM AT THAT POINT BUT SAID IT THE COULD BE DRIVEN AND NO OTHER PARTS OF THE TRANSMISSION WOULD BE AFFECTED. THERE IS A COMMON ISSUE WITH THE TRANSMISSION IN GM V8 CARS - THERE ARE MANY REPORTS OF FAILURES AND EXPENSIVE REPAIRS. IT APPEARS TO BE A DESIGN ISSUE. THE SYMPTOMS STARTED EARLY ON, AND DESPITE OUR MULTIPLE REPORTS OF PROBLEMS AND EXACT ADHERENCE TO THE MAINTENANCE SCHEDULE THERE WAS ALMOST A SERIOUS ACCIDENT. *TR

MY 2005 PONTIAC GRAND PRIX GXP WOULD OFTEN LOSE SPEED IN CURVES, CLIMBING HILLS, OR AT HIGH RATES OF SPEED. I TOOK IT TO A GM DEALER AND WAS DIAGNOSED WITH TRANSMISSION PROBLEMS. I WAS QUOTED ONE PRICE FOR TRANSMISSION, LABOR, AND RADIATOR REPLACEMENTS, BUT ENDED UP PAYING OVER $4000. GWATNEY IN NORTH LITTLE ROCK, AR HAS A HORRIBLE SERVICE STAFF. THEY WERE NOT WILLING TO WORK OUT A DEAL EVEN AFTER INFORMING THEM I WAS QUOTED A DIFFERENT PRICE. THEY THREATENED TO CHARGE ME ADDITIONAL STORAGE FEES IF I DIDN'T PICK UP MY CAR. I EVENTUALLY PAID, BUT I WROTE IN DISPUTE OF PRICE ON THE RECEIPT. HERE I AM 9 MONTHS LATER WITH THE SAME PROBLEM! GO FIGURE. *TR

MY 2005 PONTIAC GRAND PRIX GXP TRANSMISSION JUST STOPPED WHILE I WAS DRIVING. I HAVE READ HOW ABOUT 225 PEOPLE HAVE DOCUMENTED ON A WEBSITE OF THEIR TRANSMISSION ISSUES WITH THIS SAME MAKE AND MODEL VEHICLE HERE HTTP://WWW.GMLS4.COM/INDEX.PHP/TOPIC,33.0.HTML WITH MY CAR ONLY HAVING AROUND 80,000 MILES AND HAS NOT BEEN DRIVEN HARD I AM REALLY DISAPPOINTED IN GM FOR MAKING A VEHICLE LIKE THIS. THE TRANSMISSION IS NOW WHINING AND I CAN DRIVE IT ABOUT TEN YARDS AND THERE WILL BE LOSE OF POWER AND IT WILL NOT DRIVE IN ANY GEAR ON THE VEHICLE. I AM VERY DISAPPOINTED AND NEED THIS CORRECTED AND WILL ULTIMATELY NEED A NEW TRANSMISSION WHICH WILL ULTIMATELY HAVE THE SAME PROBLEM DOWN THE ROAD. *TR

ON 1/23/12, WHILE BACKING OUT OF A PARKING SPACE ON A LEVEL LOT, MY 2005 PONTIAC GRAND PRIX LUNGED FORWARD. I IMMEDIATELY HIT THE BRAKE. THE CAR WAS IN REVERSE NOT DRIVE! I ATTEMPTED TO BACK OUT AGAIN AND THE SAME THING HAPPENED! THE SECOND TIME IT LUNGED FORWARD SO QUICKLY I WAS AFRAID THE CAR WOULD NOT STOP, EVEN WITH THE BRAKE FULLY APPLIED. THIS SECOND LUNGING INCIDENT DAMAGED/CRACKED THE AIR DAM, AS IT WAS NOW WEDGED AGAINST THE CONCRETE PARKING SPACE DIVIDER. AT THE SAME MOMENT, THE DASHBOARD FLASHED/LIT UP LIKE A CHRISTMAS TREE....AND THE ENGINE STALLED. I PUT THE CAR IN PARK AND TURNED THE IGNITION OFF..THEN GOT OUT TO INSPECT THE DAMAGE. UPON RE-ENTERING THE CAR, IT WOULD NOT START! IT FINALLY RESTARTED ON THE THIRD ATTEMPT AND I WAS FINALLY ABLE TO BACK OUT OF THE PARKING SPACE. *TR

I HAVE A 2005 GRAND PRIX GXP IN WHICH THE TRANSMISSION HAS FAILED. I TOOK THE VEHICLE IN FOR SERVICE LAST YEAR BECAUSE IT WOULD HESITATE FROM A STOP AND SLAM VIOLENTLY INTO FIRST GEAR. AT THE TIME THE DEALER COULD NOT REPRODUCE THE CONCERN AND TOLD ME TO BRING IT BACK WHEN IT GOT WORSE. MY EXTENDED WARRANTY THAT I PURCHASED SEPARATELY FROM GMPP EXPIRED ON THE 22ND OF SEPTEMBER. THIS IS A DANGEROUS FLAW WHEN YOU ARE UNABLE TO ACCELERATE WHEN PULLING INTO TRAFFIC, ESPECIALLY ON THE GXP MODEL WHICH HAS OVER 300 HORSEPOWER AND TORQUE STEER THAT IS HARD TO CONTROL WHEN IT FINALLY SHIFTS INTO GEAR. *KB
