2006 PONTIAC GRAND PRIX Complaints

MY CAR SLAMS INTO GEAR FROM A DEAD-STOP. IT GRINDS VERY LOUDLY WHEN THEN TCC IS APPLIED. SHIFTS HARD AND SHAKES VERY VIOLENTLY, SOMETIMES TO THE POINT WHERE IT IS ALMOST UNDRIVABLE. GM DEALER REFUSES TO ACKNOWLEDGE THE PROBLEM BECAUSE THEY DON'T WANT TO FIX IT. THEY CLAIMED THE GRINDING NOISE IS A TICK OR RATTLE CAUSED BY TIMING CHAIN FOR THE DISPLACEMENT ON DEMAND WHEN THE ENGINE GOES FROM 8 TO 4 CYLINDERS. THE TSB ONLY STATES IT WOULD MAKE THE NOISE WHEN GOING FROM 8 TO 4, NOT 4 TO 8. MY CAR ONLY MAKES THE NOISE WHEN I'M ON THE THROTTLE, SO IT WOULD NOT BE GOING INTO 4 CYLINDER MODE. GM ARE A BUNCH OF LYING DIRTBAGS WHO DON'T WANT TO FIX THE PROBLEMS THEY CAUSE. THEY COMPROMISED THE RELIABILITY OF THIS TRANSMISSION TO MAKE IT SHIFT SMOOTHER. I'M A MEMBER OF AN ONLINE FORUM OF JUST THE LS4/4T65E-HD FWD CARS AND THERE ARE OVER 138 PEOPLE WITH THESE CARS WHO HAD OR ARE HAVING TRANSMISSION PROBLEMS/FAILURES. WHY HASN'T THERE BEEN SOME KIND OF RECALL YET? THIS IS CERTAINLY A BIG ENOUGH PROBLEM TO WARRANT A RECALL! *TR

WHILE PARKING THE CAR AND MOVING IT IN MY BUILDING PARKING LOT THE AIR BAGS DEPLOY SO FAST AND HARD THAT BROKE THE WINDSHIELD BOTH AIR BAGS CAME ON, I CALLED MY INSURANCE THEY HAVENT DONE NOTHING I FILE A CLAIM AND I HAVE BUMPER TO BUMPER WARRANTY THEY DONT WANT TO COVERED IT AND I CALLED THE DEALER THEY SAID FOR ME TO CALL GM CORPORATED. NO ONE WANTS TO DO ANYTHING MY SON HURT HIS HAND AND DRIVER GOT HIT ON HIS SHOULDER THE CARS IS STILL AT THE PARKING LOT WHERE I LIVE AT, THE AIR BAGS DEPLOY FOR NO CAUSE NO ACCIDENT. *TR

2006 GM GRAND PRIX. CONSUMER STATES PROBLEM WITH VEHICLE HEADLIGHTS *TGW THE CONSUMER STATED THE HEADLIGHTS WENT OUT WHILE DRIVING IN A RURAL AREA. THE CONSUMER EXITED OFF THE HIGHWAY AND TURNED OFF THE ENGINE. AFTER 10 MINUTES, SHE STARTED THE VEHICLE AGAIN AND ONLY THE HIGH BEAM LIGHTS CAME ON. THE NEXT DAY, THE CONSUMER CALLED AN AUTO PARTS STORE AND THEY SUGGESTED REPLACING A RELAY PART. *JB

WHILE DRIVING AT NIGHT, ON A BUSY ROAD, THE HEADLIGHTS SIMPLY WENT OFF. AFTER TRYING TO TURN THEM BACK ON WITHOUT SUCCESS, WE HAD TO CONTINUE DRIVING WITH THE HIGH BEAM HEADLIGHTS ON TO GET HOME. THE NEXT DAY THE HEADLIGHTS WORKED. THIS CONTINUES TO HAPPEN PERIODICALLY. SOMETIMES, THE HEADLIGHTS WILL NOT COME ON FROM A COLD START. OTHER TIMES, THE HEADLIGHTS FLASH OFF AND ON WHILE DRIVING. THIS IS A CRITICAL SAFETY ISSUE.

2006 PONTIAC GRAND PRIX GXP TRANSMISSION FAILURE AT 60,000 AND 100,000 MILES. *TR

HAVING SAME ISSUE AS OTHERS ON THIS WEBSITE IN REGARDS TO 2006 PONTIAC GRAND PRIX HEADLIGHTS. I HAVE BEEN DRIVING AND ALL OF A SUDDEN HEADLIGHTS WILL SHUT OFF. CAN BE OFF FOR 20 TO 30 MINUTES THEN KICK ON AGAIN, OR HERE RECENTLY DOESN'T COME BACK ON AT ALL. I HAVE REPLACED THE FUSES, HEADLIGHTS AND SWITCHES. MY CAR IS CURRENTLY IN THE SHOP TO REPLACE THE SWITCH AGAIN FOR THE SECOND TIME IN LESS THAN 2 YEARS. *TR

TRANSMISSION SHUDDER AT CRUISING SPEEDS. DELAY WHEN LEAVING FROM DEAD STOP. CAR SLAMS INTO GEAR HARD. GRINDING/CRUSHING SOUND. *LN

MY TRANSMISSION HAS NOT FAILED COMPLETELY AS OF YET, BUT I AM EXPERIENCING A LOT OF PROBLEMS WITH IT.THE CAR SHUDDERS VIOLENTLY DURING ACCELERATION. SOMETIMES MORE SEVERE THAN OTHERS. VERY NOTICEABLE LOSS OF POWER. HAD THE TRANSMISSION SERVICED AND THE FLUID WAS ALMOST BLACK AND THERE WAS A EXCESSIVE AMOUNT OF METAL OR TCC MATERIAL IN THE BOTTOM OF THE PAN. CAR JUST REACHED 65,000 MILES. *TR

TRANSMISSION FAILURE, THE TRANSMISSION FAILS TO FULLY ENGAGE IN TO ANY GEAR WHEN IT IS SUPPOSED TO, IT WILL SLIP AND CATCH FROM A STOP, THE TORQUE CONVERTER FAILS TO LOCK UP AND ALL GEARS SLIP UNDER MODERATE TO HEAVY ACCELERATION. *TR

NO MAJOR EVENTS LEADING UP TO THE FAILURE, JUST AVERAGE CITY/HIGHWAY DRIVING WITH LITTLE TO NO AGGRESSIVE ACCELERATION. REGULAR MAINTENANCE IS ALWAYS TAKEN CARE OF. THE TRANSMISSION IN MY 2006 GRAND PRIX GXP, WITH 88,000KM, LIKES TO SLIP EVERY NOW AND THEN AND SOMETIMES FAILS TO ACCELERATE UNTIL IT THE RPMS REACH ABOUT 1800, THEN IT FINALLY CATCHES AND PULLS HARD. THIS DOES NOT HAPPEN ALL THE TIME, BUT I'M WORRIED THE TRANSMISSION IS TAKING DAMAGE EVERYTIME IT DOES OCCUR, AND MAY EVENTUALLY LEAD TO A FAILURE, POSSIBLY RESULTING IN A CRASH. NOTHING HAS BEEN DONE YET TO FIX THE PROBLEM, AS IT ONLY HAPPENS A FEW TIMES WEEK, AND MY POWERTRAIN WARRANTY HAS EXPIRED. I'VE DONE SOME RESEARCH, AND JUDGING BY MY SOURCES, THE TRANSMISSION MATED TO THE 5.3L LS4 VA FRONT DRIVE GM VEHICLES IS RATED AT 280LB-FT OF TORQUE, WHILE THE MOTOR IS CLEARLY ADVERTISED AT 323LB-FT OF TORQUE. THANK YOU FOR YOUR TIME. *TR
