ENGINE
DURING HARD BRAKING, ENGINE OIL DRIPS ONTO THE ENGINE EXHAUST MANIFOLDS. THERE IS A STRONG SMELL OF BURNING OIL WHEN PARKING THE CAR AFTER DRIVING. THE VIN WAS ORIGINALLY LISTED AS BEING ELIGIBLE FOR NHTSA RECALL # 15V201, BUT A RECENT SEARCH DOES NOT LIST IT ANY LONGER EVEN THOUGH IT EXHIBITS THE CONDITION. I AM CONCERNED WITH THE RISK OF AN ENGINE COMPARTMENT FIRE IF THIS IS NOT REPAIRED SOON.

ENGINE
ON 9/26/14 I TOOK THE VEHICLE IN FOR A RECALL FOR UNINTENTIONAL IGNITION KEY ROTATION. THE VEHICLE WAS SUPPOSEDLY REPAIRED. BUT WHEN I ATTEMPTED TO PULL OUT OF THE DRIVEWAY AT BILL RAPP PONTIAC SERVICE THE VEHICLE SHUT DOWN AGAIN. IT SAID IN THE INFORMATION DATA THAT "START UP FAILURE DUE TO ELECTRICAL THROTTLE MALFUNCTION. REDUCED ENGINE POWER." I WAITED APPROXIMATELY 30 SECONDS AND ATTEMPTED TO RESTART THE VEHICLE WHICH DID START UP. ON APPROXIMATELY 9/29/14 WHILE ENTERING INTERSTATE 81N IN SYRACUSE, NY, THE VEHICLE ONCE AGAIN SHUT DOWN ON THE HIGHWAY. I CONTACTED BILL RAPP PONTIAC SERVICE DEPARTMENT AND WAS TOLD THAT I NEEDED TO BRING IN THE VEHICLE AGAIN BUT THAT I WOULD HAVE TO PAY FOR ANY FURTHER SERVICES SINCE THERE IS CURRENTLY NO OTHER RECALL FOR THE 2005 PONTIAC GRAND PRIX EXCEPT FOR THE ONE WITH THE KEY ROTATION ISSUE. WHAT CAN I DO? MY CAR IS STILL SHUTTING DOWN IN STREET AND HIGHWAY TRAFFIC.

ENGINE
SINCE WE PURCHASED THIS VEHICLE IN DECEMBER 2013 THERE HAS BEEN FOUR INCIDENTS WHERE THE ENGINE TOTALLY SHUT DOWN WHILE IN TRAFFIC WITHOUT WARNING. THE FIRST TWO INCIDENT OCCURRED WHILE MY DAUGHTER WAS DRIVING WHILE AWAY AT COLLEGE WITH THIS VEHICLE. ON APPROXIMATELY 5/17/14, WHILE ON INTERSTATE 287 (60MPH) THE VEHICLE SHUT OFF WITHOUT WARNING. ON APPROXIMATELY 6/20/14 IN S. ORANGE, NJ THE VEHICLE SHUT OFF WITHOUT WARNING IN STREET TRAFFIC (28MPH). THE THIRD AND FOURTH INCIDENTS HAPPENED WHEN I WAS DRIVING THE VEHICLE ON APPROXIMATELY 8/7/14 AT A STOP LIGHT (0MPH) WHILE WAITING FOR THE SIGNAL TO CHANGE THE VEHICLE SHUT DOWN TOTALLY. ON 9/1/14 WHILE DRIVING ON INTERSTATE 81N THE VEHICLE TOTALLY SHUT OFF WITHOUT WARNING. ONCE THE ENGINE SHUT DOWN, THE CHECK ENGINE LIGHT CAME ON, A MESSAGE READ "LOSS OF ENGINE POWER' CAME ON. I WAS DRIVING APPROXIMATELY 72MPH AND CAME VERY CLOSE TO CAUSING A MAJOR ACCIDENT WITH THREE OTHER CARS AND A TRACTOR-TRAILER. I WAS IN THE PASSING LANE ATTEMPTING TO PASS THE TRUCK WITH THREE OTHER VEHICLES BEHIND ME. WHEN I ATTEMPTED TO ACCELERATE THE VEHICLE SHUT DOWN. THE LIGHTS ON THE DASH BOARD WENT BLACK AND THE STEERING WHEEL LOCKED. THE CAR BEHIND ME WENT INTO A DITCH ON THE LEFT, WHILE THE SECOND CAR SWERVED TO THE RIGHT TO AVOID A COLLISION WITH ME. I HAD BEEN DRIVING FOR APPROXIMATELY THREE (3) HOURS FROM S. ORANGE, NJ TO SYRACUSE, NY. I WAS USING ONLY THE IGNITION KEY AND THE CAR REMOTE ON THE KEYRING. NO OTHER ITEMS WERE ON THE KEY RING. FORTUNATELY THERE WAS NO ONE INJURED AND NO CRASH OCCURRED. I AM NOT USING THIS VEHICLE BECAUSE I AM TERRIFIED TO DRIVE IT. THIS IS ESPECIALLY DISTURBING SINCE THIS VEHICLE WAS PURCHASED FOR MY DAUGHTER WHO IS AWAY AT COLLEGE. THIS IS MORE THAN AN UNINTENDED KEY ROTATION AS GM IS CLAIMING. PLEASE, I NEED YOUR HELP. THIS VEHICLE IS VERY DANGEROUS. PURCHASE MILEAGE = 56,372, CURRENT MILEAGE = 58,824.

ENGINE
ACCELERATING ON THE EXPRESSWAY IN TRAFFIC UP 40 MPH, DRY CONDITIONS. VEHICLE IN FRONT OF ME STOPPED QUICKLY. WHEN I DEPRESSED THE BRAKE HARD, I HAD NO ABS ASSIST. UPON IMPACT, THE AIRBAGS DID NOT DEPLOY EVEN THOUGH IT WAS A HIGH ENERGY IMPACT. THE VEHICLE DAMAGE CAUSED THE VEHICLE TO BE SCRAPPED AND NOT FIXED. BASED ON THE VEHICLE SPEED AND RATE OF DECELERATION, I WOULD EXPECT THAT THE ABS SYSTEM WOULD HAVE BEEN ENGAGED AND THE AIRBAGS SHOULD HAVE DEPLOYED. IF THE ABS WOULD HAVE BEEN ENGAGED, I BELIEVE THE VEHICLE WOULD HAVE STOPPED IN TIME. THE VEHICLE IN QUESTION HAS BEEN RECALLED FOR AN IGNITION SWITCH DEFECT THAT CAUSES THE DISABLING OF THE ABS AND AIRBAGS. DRIVER SUSTAINED A SPRAINED ANKLE.

ENGINE AND ENGINE COOLING
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.

ENGINE AND ENGINE COOLING
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.

ENGINE AND ENGINE COOLING
TL*THE CONTACT OWNS A 2005 PONTIAC GRAND PRIX. WHEN THE WINDOW DEFOGGER IS ACTIVATED AND THE WINDSHIELD WIPERS ARE ENGAGED, THE VEHICLE SHUTS DOWN. WHILE DRIVING 70 MPH, THE VEHICLE STALLS AND LOSES POWER. THE MECHANIC STATED THAT THE O-RING WAS MISSING, WHICH CAUSES THE VEHICLE TO LOSE POWER DUE TO LACK OF HEAT. THE MECHANIC WAS UNABLE TO DUPLICATE THE FAILURE. WHEN THE CONTACT TOOK HER VEHICLE TO THE DEALER, IT WAS STILL UNDER WARRANTY. HOWEVER, WHEN SHE PICKED UP HER VEHICLE FROM THE DEALER, SHE NOTICED THAT 100 MILES HAD BEEN ADDED, WHICH PUT THE VEHICLE OUT OF WARRANTY. THE FAILURE PERSISTS. THE CURRENT MILEAGE IS 37,000 AND FAILURE MILEAGE WAS 35,000.

ENGINE AND ENGINE COOLING
2005 PONTIAC GRAND PRIX GT SEDAN VIN #[XXX] PURCHASED 12/16/2004. INTERMITTENTLY VEHICLE STALLS/ LOSS OF POWER IN THE ENGINE. WHILE DRIVING THE VEHICLE IT WILL SUDDENLY JUST LOSES POWER. YOU CONTINUE TO PRESS THE ACCELERATOR PEDAL AND THEN THE ENGINE WILL SUDDENLY TAKE BACK OFF AT A GREAT SPEED. THIS HAS HAPPENED WHILE DRIVING NORMALLY WITHOUT TRYING TO ACCELERATE AND ALSO WHILE TRYING TO ACCELERATE. THE CAR HAS LOST POWER WHILE TRYING TO MERGE IN TRAFFIC. THE CAR HAS LOST POWER WHILE TRYING TO CROSS HIGHWAYS. THE CAR HAS LOST POWER WHILE JUST DRIVING DOWN THE ROAD. GMC HAS PERFORMED THE FOLLOWING REPAIRS WITHOUT FIXING THE PROBLEM. 12/30/2004 [XXX]-MODULE, POWERTRAIN CONTROL-ENGINE REPROGRAMMING. 01/24/2005 [XXX]-SOLENOID,PRESSURE CONTROL-REPLACED. 02/04/2005 [XXX]-MODULE, PCM/VCM-REPLACED. 02/14/2005 [XXX]-PEDAL,ACCELERATOR-REPLACED. DEALERSHIP PURCHASED FROM CAPITAL BUICK-PONTIAC-GMC 225-293-3500. DEALERSHIP HAS ADVISED THAT THEY DO NOT KNOW WHAT IS WRONG WITH THE CAR. WE HAVE BEEN TOLD THAT WE HAVE TO GO DIRECT TO PONTIAC WITH THE PROBLEM. HAVE BEEN IN CONTACT WITH PONTIAC SINCE 02/15/05. PONTIAC ADVISED THAT THEY WERE GOING TO RESEARCH THE PROBLEM AND SEE IF ANY OTHER GRAND PRI WAS REPORTING LIKE PROBLEMS. SO FAR THE ONLY ADVICE FROM PONTIAC IS THEY WANT US TO COME IN AND TAKE ANOTHER GRAND PRIX OFF THE LOT AND SEE IF WE CAN GET THIS CAR TO DUPLICATE THE SAME PROBLEM. THIS DID NOT IMPRESS ME AT ALL. SO AFTER WAITING FOR 2-1/2 MONTHS FOR PONTIAC TO DO SOMETHING TO FIX THE PROBLEM, I HAVE DECIDED TO REPORT THIS TO NHTSA. *AK *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE AND ENGINE COOLING:ENGINE
"CHARGING SYSTEM FAILURE" HAS APPEARED AT LEAST 12 TIMES ON THE DRIVER'S MESSAGE CONSOLE THAT I HAVE DOCUMENTED. IT IS ALSO ACCOMPANIED BY THE FAN BLOWER REPEATEDLY CUTTING IN AND OUT WHEN TURNED ON. THIS HAS HAPPENED JUST ABOUT EVERY TIME THE FAN IS TURNED ON. HAVE TAKEN THE VEHICLE IN TO HAVE THE PROBLEM CHECKED AT LAMBERT PONTIAC-BUICK IN CUYAHOGA FALLS, OHIO, AND THEY STATED THEY RAN A COMPUTER DIAGNOSTIC AND COULD NOT DETERMINE WHAT THE PROBLEM WAS, AND STATED THERE WAS NOTHING THEY COULD DO ABOUT IT. ALSO, ONE TIME WHILE ACCELERATING IT SOUNDED AS IF THE ENGINE WERE ABOUT TO CUT OFF, BUT IT DID NOT. VEHICLE ONLY HAS 3200 MILES ON IT.
