2007 PONTIAC GRAND PRIX Complaints

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

WHILE DRIVING AT NIGHT, HEADLIGHT LOW BEAMS TURNED OFF AUTOMATICALLY. HIGHBEAMS AND TURNING SIGNALS WORK FINE. CHECKED FUSES, THEY WERE GOOD. CHECKED BULBS, THEY WERE GOOD. LOWBEAM HEADLIGHTS STILL WILL NOT WORK. *TR

AUTOMATIC TRANSMISSION FAILURE. TRANSMISSION SHUDDERS, SLIPS AND SLAMS INTO GEAR. GXP MODEL. *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.

I WAS DRIVING DOWN THE ROAD ON A SATURDAY NIGHT WHEN ALL OF A SUDDEN THE ROAD BECAME DARK. I GOT OUT TO SEE IF MY HEADLIGHTS WERE ON AND THEY WEREN'T . SO I GOT BACK IN THE CAR AND BEGAN TO CHANGE THE HEADLIGHT SWITCH FROM AUTOMATIC TO ON. NOTHING. THEN I WENT FROM LOW BEAM TO HIGH AND AGAIN NOTHING. THEY I HAD MY FUSE BOX CHANGED AS WELL AS THE GROUND WIRE. NOTHING. I BEGAN TO RESEARCH ONLY TO FIND OUT ALOT OF PEOPLE HAVE STARTED TO HAVE THIS PROBLEM STARTING AUGUST 2010 UNTIL PRESENT (10/2011). *TT

WHILE DRIVING AT NIGHT, THE LOW BEAMS ON MY CAR SUDDENLY FAILED, AND I COULD NOT GET THEM TO GO BACK ON. FORTUNATELY, THE HIGH BEAMS STILL WORKED. SUBSEQUENTLY, THE SAME THING HAPPENED WITH MY DAY RUNNING LIGHTS WHICH ARE TIED IN WITH THE LOW BEAMS. I TOOK THE CAR TO THE LOCAL PONTIAC DEALERSHIP AND IT WAS UNSUCCESSFUL IN DUPLICATING THE PROBLEM. I THEREFORE DECIDED TO GOOGLE THE ISSUE TO DETERMINE IF THERE WERE OTHERS WHO SHARED THE SAME PROBLEM WITH THE SAME MAKE, MODEL, AND YEAR AS I OWNED. LO & BEHOLD, THERE WERE NOT A FEW WHO ALSO EXPERIENCED LOW-BEAM HEADLIGHT FAILURE. I ALSO NOTED THAT THIS PROBLEM WAS NOT SPECIFIC TO JUST 2007 MODEL YEAR PONTIAC GRAND PRIXS, BUT ALSO OTHER MODEL YEAR GRAND PRIXS, AND EVEN SOME BUICK MODELS). SOME POSTERS HAD SUGGESTED THAT THE ISSUE WAS WITH A RELAY, GM PART # 15016745, AND ONCE THEY REPLACED THIS PART, THEY NEVER HAD THE PROBLEM REOCCUR. SINCE I WAS HESITANT TO PURCHASE A PART OF WHICH I HAD NO GUARANTEE THAT IT WOULD WORK, I WENT TO THE WEB SITE JUSTANSWERS.COM, AND PAID A GM EXPERT $35 IN HOPES THAT HE COULD HE COULD FIND RESOLUTION. HE INDICATED THAT THE LOW BEAM FAILURE WITH MY CAR WAS COMMON, AND HE, TOO, RECOMMENDED GM PART # 15016745, WHICH IS LOCATED IN THE UNDER-HOOD FUSE BLOCK. I PURCHASED THE RELAY WHICH I FOUND ON GMPARTS.COM, AND RECEIVED IT YESTERDAY. I HAVE, YET, TO INSTALL IT, AND I'M HOPING THAT THAT IS THE PROBLEM. IT IS FRIGHTENING TO HAVE YOUR HEADLIGHTS FAIL WHILE DRIVING AT NIGHT. I AM WRITING YOU SO THAT YOU MIGHT INVESTIGATE THIS ISSUE, AND ABATE ANY POTENTIAL ACCIDENTS. NO ONE REALLY KNOWS IF THERE HAVE ALREADY BEEN ANY DEATHS RESULTING FROM THIS SERIOUS ISSUE. THANK YOU.
