2007 Pontiac Grand Prix

2007 PONTIAC GRAND PRIX GXP TRANSMISSION FAILURE AT 96,000 MILES (AND 6 MONTHS OUT OF WARRANTY). STOPPED AT TRAFFIC LIGHT WHEN I PRESSED THE ACCELERATOR TO GO AND HEARD A "CLUNK" AND HAD NO FORWARD GEARS IN AUTOMATIC. DID HAVE TAPSHIFT GEARS AND REVERSE, THOUGH FORWARD GEARS SLIPPED. TOOK IT TO A LOCAL DEALER (WE WERE OUT OF TOWN) AND TOLD THE TRANSMISSION HAD FAILED. HAD TO HAVE THE TRANSMISSION REBUILT AT A COST OF $3600. PLUS CAR RENTAL AND HOTEL TO DRIVE HOME AND RETURN TO PICK UP THE CAR WHEN IT WAS REPAIRED. SECOND GM TRANSMISSION FAILURE I'VE EXPERIENCE IN LESS THAN TWO YEARS WITH THE PREVIOUS ONE ON A CHEVROLET TRAILBLAZER. *JS

DRIVING ON THE HIGHWAY AT 70 MPH AND ALL OF A SUDDEN THE CAR SHUTS DOWN, LIKE SOMEONE UNPLUGGED THE ENGINE. THIS WAS THE MOST HORRIFIC MOMENT IN MY LIFE, SEMI TRUCKS ZOOMING PAST ME. FINALLY MADE MY WAY TO THE SIDE OF THE HIGHWAY AND HAD TO CALL A TOW TRUCK, CAR WAS TOWED HOME AND THE TOW TRUCK GUY PUT THE KEY IN THE IGNITION AND IT STARTED RIGHT UP. DROVE THE CAR TO WORK AND IT SHUT DOWN AGAIN THIS TIME I WAS ONLY DOING 35 MPH. I WAITED FOR ABOUT 30 MIN AND THE CAR STARTED RIGHT BACK UP, ON MY HOME FROM WORK IT DID IT AGIN. THE FOLLOWING WEEK IT DID IT AGIAN, TOOK THE CAR TO A "GM" CERITIFIED MECHANIC BUT OF COURSE THEY COULD NOT FIND A PROBLEM, PICKED THE CAR UP AND DROVE IT FOR A FEW DAYS IT HAPPENED AGAIN, TOOK IT BACK TO THE GM MECHANIC, STILL COULDN'T FIND ANYTHING WRONG, PICKED IT UP A WEEK LATER SAME ISSUE. TO SUM IT UP I HAVE HAD THE IGNITION MODULE AND THE CRANK SENSOR SHAFT AND STILL CAN NOT LOCATE TH PROBLEM. THE CAR IS TOO DANGEROUS TO DRIVE AND NOW IT'S JUST SITTING IN MY DRIVEWAY AND WON'T START AT ALL. GM REALLY NEEDS TO TAKE A LOOK AT THIS SITUATION BRFORE SOMEONE GETS REALLY HURT, THE CAR IS DEFECTIVE. *TR

I HAVE A 2007 PONTIAC GRAND PRIX GXP W/5.3L V8. CURRENTLY HAS 45,000 MILES JUST RECENTLY STARTED HAVING ISSUES WITH THE TRANSMISSION. FROM A DEAD STOP TRANS WILL SLIP, THAN SLAM INTO GEAR, ALSO SHUTTERS BETWEEN 1-2, AND SOMETIMES FROM 3-4. CAR DOES CURRENTLY HAVE POWERTRAIN WARRANTY THAT I PURCHASED WITH CAR. SO CAR WILL BE GOING IN FOR REPAIR UNDER WARRANTY (I HOPE) AFTER READING ONLINE IN A GM OWNER FORUM FOUND OUT ABOUT THE CURRENT INVESTIGATION WITH GM TRANSMISSION FAILURES WOULD REALLY LIKE TO SEE A RECALL COME OF THIS. BECAUSE SEEMS THAT THIS IS A VERY COMMON ISSUE.. IT WILL LEAVE YOU STRANDED WITHOUT WARNING, AND MAY BREAK IN THE MIDDLE OF TRAFFIC CAUSING A DANGEROUS SITUATION TO BE IN. IT SEEMS TO BE TOO MUCH FOR A TRANSMISSION THAT WAS DESIGNED TO BE MATED TO A V6 ENGINE. NOT TO BE MATED TO A 5.3L V8. *TR

DRIVE GEAR WON'T ENGAGE FROM A STOP. STARTED VEHICLE AND IT STALLED. REVERSE OUT OF PARKING SPOT AND PUT IN DRIVE TO LEAVE PARKING LOT. WENT TO ACCELERATE FROM A STOP AND ENGINE REVVED AND WOULD NOT MOVE LIKE IT WAS IN NEUTRAL. HAD TO PLACE VEHICLE IN 1ST GEAR TO MOVE UP THROUGH 3RD AND THEN PUT IN DRIVE AFTER GETTING UP TO SPEED. PROBLEM STARTED WITHOUT WARNING AND MILEAGE IS ONLY AT 84,400. NEVER HAD A GM VEHICLE WITH THIS TYPE OF ISSUE BEFORE AND I HAVE ONLY OWNED GM. VERY DISAPPOINTED. *TR

THE CAR HAS HAD OFF AND ON TRANSMISSION ISSUES. FROM A STOP, WHEN TRYING TO ACCELERATE. IT BOGGED BADLY, LIKE IT WAS IN 2ND, SUDDENLY IT SLAMMED INTO FIRST AND I WAS ON MY WAY. THERE HAVE BEEN SEVERAL INSTANCES OF ROUGH SHIFTS. ALSO, AT TIMES I'LL BE GOING VERY SLOW 0-10MPH AND NEED TO ACCELERATE IN TRAFFIC. THE CAR HESITATES FOR A SECOND BEFORE REGAINING RPM. I HAVE NOT BEEN STRANDED YET BUT WANTED TO RECORD THE INCIDENTS. I HAVE BEEN VERY HAPPY WITH THIS CAR AND THE 4 GMS I DROVE BEFORE ( ALL 100K+, 2 OF THEM 220K+), BUT THESE ISSUES ARE STARTING TO WORRY ME. *TR

NEW OWNER OF PONTICA GRAND PRIX. NEVER OWNED A PONTICA, PURCHACE FOR WIFEY RED COLOR SHE LIKE IM A PRO MECHANIC 20 YEARS OR BETTER AND HAD DID THE RESEARCH HEARD ABOUT TRANS IN PONT. FAILURE ALSO DOOR ACTURATOR BEEN BAD COULD BET THE PRICE 2 MONTHS LATER TRANS B/O (BAD OPERATION) I DROP PAN AND FOUND THE FOWARD BAND BROKEN IT LOOK LIKE IT WAS STOP WELDED ON AND BROKE RIGHT AFTER THE SPOT WELD SHOULD HAVE BEEN CAST ONE PIECES BUT NO! (I BELIEVE DEFECT IN MANUFACTURING) SHOULD HAVE BEEN CASTED I LOVE USA BUT IF THEY DONT STAND-UP ITS NISSIAN FOR ME. I REPLACE TRANS. LKQ LOW MILES 25,000! WILL BE TRADING FOR GUEST WHAT WONT BE GM! YOU STOP WELD BODY PARTS NOT TRANS PARTS BY GM THEY SHOULD'NT GOT BAIL OUT NOT JUST PONTICA THE TRANS 4T65E ARE DEFECTS 2007 UPLANDERS ECT IF U HAVE A 3.8 LOOK OUT GM MESSED UP THIS ONE. *TR

THE ISSUES I HAVE WITH MY 07 PONTIAC GRAND PRIX GXP ARE THE FOLLOWING MORE OFTEN THAN NOT NOW WHEN TAKING OFF FROM A STOP TRANSMISSION REVS UP AND SLAMS INTO GEAR CAUSING WHEEL SPIN GOING DOWN HIGHWAY TORQUE CONVERTER WILL LOCK UP AND RELEASE AT CRUISING SPEEDS 65-70 MPH CAUSING CAR TO BUCK ERRATICALLY CAUSING STABILITY ISSUES. *TR

TL* THE CONTACT OWNS A 2007 PONTIAC GRAND PRIX. THE CONTACT STATED THAT WHEN DRIVING AT VARIOUS SPEEDS, THE LOW BEAM HEADLIGHTS WOULD FAIL SPORADICALLY. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY ADVISED HIM THAT THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS APPROXIMATELY 80,000. THE VIN WAS UNAVAILABLE.
