2006 PONTIAC GRAND PRIX Power Train Problems

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. THE CONTACT STATED THAT WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE STALLED UPON DEPRESSING THE BRAKE PEDAL WITH THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT RESTARTED THE VEHICLE. NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 95,000.

Mileage: 95,000

ENGINE SHUTS OFF IN THE MIDDLE OF DRIVING AND SAYS STARTING DISABLED DUE TO ELECTRIC THROTTLE CONTROL, REDUCED ENGINE POWER, ABS TRACTION CONTROL OFF. THIS HAPPENS WHILE MOVING AT THE CORRECT SPEED ON THE HIGHWAY, STOPPED AT A STOP LIGHT IN THE CITY, AND WHILE MAKING TURNS. SOMETIMES WHEN IT HAPPENS I LOSE POWER STEERING AND HAVE ALMOST O CONTROL OF WHERE MY CAR GOES. AT FIRST THIS ONLY HAPPENED ABOUT ONCE A WEEK, BUT NOW IT CAN HAPPEN UP TO 10+ TIMES A DAY

Mileage: 137,000

WHILE DRIVING MY CAR ON STREET I WAS STRUCK ON THE PASSENGER SIDE IN A INTERSECTION WHEN A CHEVY MAXI VAN STRUCT ME WHEN RUNNING A RED LIGHT. MY AIRBAG DID NOT DEPLOY AND MY VEHICLE WAS TOTALLED. I SUSTAINED BODY INJURIES SUCH AS BACK AND NECK AND FINANCIAL HARDSHIP. I HAVE NEVER RECOVERED FROM THESE INJURIES.

I'VE HAD TO REPLACE THE TRANSMISSION AT 67K MILES, AND IT WENT OUT ON ME AGAIN AT 110K MILES. I REPLACED THE TRANSMISSION AT NOT ONLY A GM CERTIFIED DEALERSHIP, BUT A PONTAIC DEALERSHIP (JOHN HINE PONTAIC) IN SAN DIEGO. THE TRANSMISSION WAS A GM CERTIFIED REFURBISH FROM CANADA. NO RECALLS FROM GM, AND NO REIMBURSEMENT POLICY. THIS IS AN ISSUE.

Mileage: 110,250

STEERING: CLICKING NOISE WHEN TURNING TRANSMISSION HAS A LIGHT SLIP INTO 1ST AND SOMETIMES HARD SHIFT INTO 2ND HAD THIS LOOKED AT IN 2013 WHILE IT WAS STILL UNDER WARRANTY AND THE DEALER DIDN'T WANT TO ACKNOWLEDGE THERE WAS A PROBLEM. THIS SHOULD BE UNDER RECALL SINCE MORE PEOPLE HAVE THIS SAME PROBLEM.

I BROUGHT THIS CAR JANUARY 12TH 2015 THE NEXT WEEK I HAD TO TAKE IT TO THE SHOP TO GET WORK DONE TO THE ENGINE I GOT IT BACK IT RAN GOOD FOR LIKE AN MONTH AND I HAD TO TAKE TO A DIFFERENT SHOP AND THEY TOLD ME I NEED A NEW ENGINE AND MY WARRANTY COMPANY DIDN'T WANT TO COVER IT SO I HAD TO PAY TO GET MY AFTER THE WARRANTY COMPANY SAID THEY WOULD PAY TO GET IT FIX THAT WAS ALMOST 1500 FOR NOTHING I HAD TO PAY ANOTHER 700 FOR ENGINE AND ON JULY 27TH 2015 THE TRANSMISSION STOP GOING INTO DRIVE AND THE LOWEST PRICE I HAVE FOR THAT IS 2500 THIS ALOT OF MONEY TO BE MAKING PAYMENTS ON AND ONLINE ALL I AM SEEING IS BAD REVIEWS OF THIS CAR I NEED TO KNOW IS THERE ANYTHING THAT CAN BE DONE ABOUT THIS BECAUSE THIS IS RIDICULOUS.

Mileage: 126,945

THIS IS AN ISSUE IT FELT LIKE SOMEONE HIT US FROM BEHIND AND YET NO ONE WAS THERE. STARTED DRIVING AND THE NEXT THING WE KNOW THE CAR SPEEDOMETER JUST SLOWS DOWN TO 30 MPH. LUCKILY WAS ABLE TO GET OUT OF HIGH SPEED LANE BEFORE AN 18 WHEELER SMASHING INTO THE REAREND AND WOULD HAVE KILLED MY TWO KIDS!! THIS IS BULL CRAP PONTIAC GM WILL NOT DO ANYTHING ABOUT IT!! THIS HAPPENED WITH A GM ENVOY THAT I PURCHASED. I SHOULD HAVE KNOWN BETTER TO PURCHASE ANOTHER GM PRODUCT. THERE ARE WAY TOO MANY COMPLAINTS REGARDING THE TRANSMISSION AND STEERING FOR GM NOT TO DO ANYTHING ABOUT THIS THIS ISSUE, THE WORST IS THEY KNOW ABOUT AND WILL NOT DO ANYTHING ABOUT IT. SOME PEOPLE DO NOT HAVE THAT KIND OF MONEY TO JUST CRAP OUT AND CONTINUE TO CRAP OUT FOR A KNOWN ISSUE!

Mileage: 60,000

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. WHILE DRIVING APPROXIMATELY 70 MPH, THE TRANSMISSION BEGAN TO SLIP GEARS AND VIOLENTLY JERKED. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO STATED THAT THE TORQUE CONVERTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 170,000.

Mileage: 170,000

JUST THAT MY CAR WAS JERKING DOWN THE HIGHWAY.....COME TO FIND OUT BAD TRANSMISSION IN THESE CARS. I HAVEN'T HAD IT FIXED BECAUSE I DON'T HAVE THE MONEY. SO I WILL KEEP DRIVING IT UNTIL IT JUST GOES OUT OR HOPEFULLY SOMEONE STEALS IT. PIECE OF JUNK CAR AND GM KNOWS IT. I TALKED TO THEM AND THEY SAID OUT OF WARRANTY. I KNEW THEY WOULD SAY THIS BUT I WANTED TO TELL THEM I WILL NEVER BUY GM AGAIN. I ALSO HAVE TO SEE A CHIROPRACTOR NOW MAYBE BECAUSE OF ALL THE JERKING. *TR

Mileage: 120,000

ON MORE THAN ONE OCCASION, MY CAR HESITATED AFTER STOPPING AT AN RED LIGHT. UPON TAKE OFF WHILE OTHER CARS ARE BEHIND ME IF FEELS LIKE MY CAR GEARS ARE STUCK . I INITIALLY THOUGHT PERHAPS IT WAS THE WEATHER OR MAYBE MY BRAKES . NO, NOT THE PROBLEM BECAUSE MY BRAKES HAVE BEEN CHECKED AND THE WEATHER IS NOT ALWAYS A CULPRIT, I EVEN HAVE NEW TIRES . THE PROBLEM IS VERY SCARY WHEN YOUR GRANDCHILDREN ARE BUCKLE UP IN THE BACK SEAT AND YOUR CAR HESITATE, TRANSMISSION SLIPPING NOT CHANGING GEARS. THIS HAS HAPPENED FAR TO MANY TIMES FOR MY COMFORT AND SAFETY OF MYSELF AND MY FAMILY. ADDITIONALLY, THERE ALSO BEEN TIMES WHEN THE FAN STOP DURING THIS TIME. BOTH IN THE SUMMER WITH THE AIR BLOWING AND JUST TODAY (11/12/14), WITH THE HEAT BLOWING EVERYTHING STOPPED INTERMITTENTLY, WHAT IS GOING ON WITH THIS CAR! THE PROBLEM HAS ONLY GOTTEN INCREASINGLY WORST. *TR

Mileage: 130,399

SOON AFTER PURCHASE, TRANSMISSION SLIPS GEARS COMING OUT OF A STOP. AUGUST 2013, TRANSMISSION DROPPED OUT, DRIVING 30MPH. CAR WAS NOT DRIVABLE; NO GEARS. TRANSMISSION WAS REPLACED. NOW ONE YEAR LATER, SLIPS GEARS AT 40MPH. HEADLIGHTS WENT OUT WHILE DRIVING IN THE DARK. USE OF TURN SIGNALS CAUSES HIGH BEAMS TO ACTIVATE. THE CABIN FAN (A/C AND HEAT) NEVER SHUTS OFF. HEAT WORKS INTERMITTENTLY. CAR SEEMS TO SHAKE AT TIMES. FEELS LIKE A FLAT TIRE BUT WHEN CHECKED, TIRES ARE FINE. CAR ROLLS WHEN IN PARK, EVEN ON FLAT SURFACE. CAR ROLLS BACK WHEN IN DRIVE, EVEN ON SLIGHT INCLINES. NEVER CERTAIN OF BRAKES; AT TIMES, WORKS AS NORMAL, OTHER TIMES, PEDAL MUST BE PUSHED CLOSE TO THE FLOOR TO ACTIVATE BRAKES. *TR

THE TRANSMISSION SLIPS & STALLS DURING NORMAL OPERATION. BURNS EXCESSIVE AMOUNTS OF TRANSMISSION FLUID. STEERING WHILE MAKING SHARP TURNS, CAUSES MODERATE FRONT END VIBRATION. 2006 PONTIAC GRAND PRIX, SEDAN. EXCESSIVE ENGINE HEAT. *TR

Mileage: 100,000

THE TRANSMISSION BANGS INTO GEAR AND THE SPEEDOMETER GOES CRAZY. AT TIMES THE CAR WILL NOT START. I HAVE SPENT OVER 3K ON THIS FIX, WITH THREE DIFFERENT AUTO REPAIR SERVICE CENTERS, WITHOUT IT BEING RESOLVED. THE LAST REPAIR SERVICE REPLACED THE ECM (ELECTRONIC CONTROL MODULE), WHICH SEEMED TO FIX THE ISSUE FOR ABOUT 2 WEEKS, THEN IT STARTED AGAIN. I TOOK IT BACK TO THE REPAIR PLACE WHO SAID HE CLEANED THE CONDENSATION FROM THE WIRES, AND IT WORKED AGAIN FOR ABOUT 3 DAYS. I LET THE CAR SIT FOR 4 DAYS, AND DROVE FINE AGAIN, FOR ABOUT 26 MILES. IT SEEMS THAT NO MATTER WHERE I BRING MY CAR TO, EVERYONE CANNOT REPAIR IT BECAUSE THE CODES PROVIDED BY THE COMPUTER, DON'T FIX THE PROBLEM WHEN THE PARTS ARE REPLACED. I KNOW IT ISN'T THE TRANSMISSION, BECAUSE I HAD IT REPLACED WITH A REBUILT TRANSMISSION SINCE THIS WAS ONE OF THE DIAGNOSIS. I AM AT MY WITS END WITH THIS ISSUE. I CANNOT TRADE THE CAR IN BECAUSE I AM AN HONEST PERSON, AND DON'T WANT TO SELL CAR THAT I KNOW HAS AN ISSUE. *JS

Mileage: 166,000

THE INITIAL ISSUE THAT I NOTICED WAS WHEN I WAS DRIVING AT 70MPH AT ABOUT 2000 RPMS THE RPMS WOULD JUMP UP ABOUT 300 RPMS WHEN I WOULD DRIVE AT A STEADY SPEED, JUST FLAT GROUND. IT GOT WORSE AND MORE FREQUENT AS A MONTH WENT ON, SO I THEN BROUGHT TO A GM DEALERSHIP AND THEY DECIDED TO DO A TRANSMISSION SERVICE (FLUID AND FILTER) AND INSPECT WHAT THEY COULD, EVERYTHING "LOOKED GOOD". NOW SINCE THEN THIS ISSUE HAS BEEN RESOLVED BUT THE TRANSMISSION SLIPS AND SLAMS INTO GEAR, WHEN I AM IN STOP AND GO TRAFFIC OR HITTING A LOT OF STOP LIGHTS, ENGINE TEMP. DOES SEEM TO GET A LITTLE HIGH, EVEN MY MECHANIC THOUGHT SO. WHEN IT SLIPS IT FEELS AS IF I HIT A GIANT POTHOLE AND THE ENGINE/TRANSMISSION IS GOING TO FALL OUT. BUT THIS PROBLEM IS SO INTERMITTENT NO ONE CAN PIN POINT THE PROBLEM, I HAVE HAD THREE DIFFERENT MECHANICS LOOK AT THIS ISSUE AND ONE TRANSMISSION SHOP. I HAVE ALL OF THIS AND CAN'T SEEM TO RESOLVE THE ISSUE, AND NOT TO FORGET TO MENTION SINCE I HAVE OWNED THE CAR SINCE 2006, IT HAS NEVER SHIFTED SMOOTHLY FROM FIRST TO SECOND GEAR (WHEN I ACCELERATE FROM A STOP LIGHT/SIGN). I LIKE GM, BUT WHEN THIS ISSUE IS ALL OVER THE INTERNET AND GM HASN'T DONE ANYTHING ABOUT IT, I AM STARTING TO SECOND GUESS MY DECISION ON VEHICLE MANUFACTURE. *TR

Mileage: 100,000

MY MECHANIC INSISTED THAT I NEEDED TO CHANGE MY TRANSMISSION FLUID IN ORDER TO KEEP THE TRANSMISSION RUNNING EFFICIENTLY. I BELIEVED HIM AND HAD IT DONE. FROM THAT TIME, MY TRANSMISSION HAS BEEN SLIPPING FROM 1ST TO SECOND GEAR. THEN I WAS TOLD MY CAR COULD USE A TUNE UP AND THAT WOULD CORRECT THE PROBLEM? HAD A TUNE UP IN JANUARY 2014. THE TRANS DOES NOT SLIP ALL THE TIME, BUT WHEN I AM IN TRAFFIC (STOP AND GO) IT WILL SLIP SLIGHTLY. I TAKE GOOD CARE OF MY VEHICLES KEEPING UP WITH THE MAINTENANCE. I SEE OTHER COMPLAINTS VERY SIMILAR TO MINE AND FEEL THAT GENERAL MOTORS NEEDS TO BE RESPONSIBLE FOR THIS PROBLEM WITH THE TRANSMISSIONS. NOW, WHAT DOES IT TAKE TO GET A RESPONSE ON THIS SITUATION? THE WAY I FEEL NOW IS THAT I WILL NEVER OWN A GENERAL MOTORS VEHICLE IF THERE IS NO RESOLUTION TO THIS PROBLEM. *TR

I AM ADDING MY TRANSMISSION FAILURE TO THIS DATA BASE. THIS IS A ONE OWNER CAR AND DRIVEN WITH CARE. THE TRANSMISSION FAILED AT APPROMIMATELY 5 YEARS AND AT 55,045 MILES . THIS COST $4,343 TO REPLACE WITH A SRTA TRANSMISSION SO I COULD GET HOME FROM VACATION. WHY IS NOTHING BEING DONE ABOUT THE NUMEROUS TRANSMISSION FAILURE COMPLAINTS? MY CAR NOW HAS 80K MILES AND I FEEL AS IF I AM CLOSE TO LOSING THE TRANSMISSION AGAIN. I HAVE THE INVOICE TO BACK UP THIS CLAIM. *TR

Mileage: 55,045

I BEEN HAVING PROBLEMS WITH THE TRANSMISSION, IT SLIPS AND GETS TO HOT, IN A NORMAL TRIP TO WORK O THE MALL ETC, IF I DRIVE FOR 30- 40 MINTS, IT REACH UP TO 240 DEGREES, I THINK IS A CAR DEFECT, WHEN I BOUGHT THE CAR THE TRANSMISSION DIED AND THE DEALER REPLACE THE TRANSMISSION, BUT EVEN THOUGH IT WAS A NEW TRANS. IT ALSO RUN TO HOT, I CALLED GMC AND THEY DENIED ANY TRANSMISSION PROBLEMS. *TR

Mileage: 80,235

THE TRANSMISSION IS SLIPPING AS I HAVE SEEN MANY OTHERS WITH THIS SAME COMPLAINT HOWEVER ONE DEALERSHIP SAYS THEY CANT FIND ISSUE. THEY DROVE FOR ONLY 2 MILES. IT IS A SERIOUS ISSUE. CURRENTLY AT A GM DEALERSHIP TO SOLVE ISSUE. HOWEVER GM KNOWS ABOUT THIS FAULTY ISSUE AND REFUSES TO ISSUE A RECALL AFTER MANY HAVE SPENT THOUSANDS TO FIX TRANSMISSIONS! I AM NEXT THIS IS TERRIBLE. WHAT IF IT COMPLETELY GOES WHILE I HAVE MY FAMILY IN THE CAR? ARE THEY THEN GOING TO FIX? GM NEEDS TO STAND BEHIND THE CONSUMER AND FIX THIS ISSUE. *TR

Mileage: 83,000

THE TRANSMISSION ON MY 2006 PONTIAC GRAND PRIX GXP BEGAN TO"SLIP AROUND THE 70,000 MILE MARK AND HAS CONTINUED TO DO THIS TODAY AT 85,000.CAR HAS BEEN DRIVEN LIKE A GRANNY SINCE I NOTICED THE SLIPPING OF THE TRANNY AND IT REVS TO 3200RPM BEFORE SHIFTING INTO 2ND GEAR.ALSO UPON STARTING THE CAR AND PUTTING IT INTO DRIVE,OCCASIONALLY THERE IS A CLUNK TO THE TRANSMISSION. *JS

THE VEHICLE WITHOUT WARNING WOULD NOT DRIVE FORWARD AFTER COMING TO A COMPLETE STOP AT A STOP LIGHT. THE ENGINE WOULD REV UP BUT WOULD NOT GO FORWARD. ENDED UP HAVING TO PUT THE TRANSMISSION IN PARK AND TURN THE CAR OFF, THEN STARTED THE CAR AGAIN AND PUT THE TRANSMISSION IN DRIVE AND THE VEHICLE WOULD DRIVE AS IF EVERYTHING WAS OK UNTIL I STOPPED THE NEXT TIME. I WOULD HAVE TO REPEAT THIS EVERY TIME I CAME TO A STOP. NO ERROR CODE OR TRANSMISSION SIGN OF A PROBLEM. *TR

Mileage: 68,000

I HAVE A 2006 PONTIAC GXP AND I AM WRITING IN TO COMPLAIN ABOUT A TRANSMISSION FAILURE. I HAVE BEEN READING ALL OVER THE INTERNET AND THERE ARE A TON OF FAILURES. THE CAR ONLY HAS 83K AND WAS NEVER MODIFIED OR CHANGED. IT IS GOING TO COST OVER 3300 TO FIX THIS ISSUE. *TR

2006 PONTIAC GXP, DECEMBER 2013 TRANSMISSION STARTING SLIPPING ON INTERSTATE NEAR CHARLOTTE NORTH CAROLINA. CAR TRANSMISSION THEN COMPLETELY STOPPED WORKING, NO FORWARD OR REVERSE. CAR HAS 86,000 MILES ON ODOMETER. VEHICLES TOWED TO VIRGINIA. HAD VEHICLE TRANSMISSION CHECKED BY GM AND PRIVATE AUTO SHOP, NO CODES FOUND, BOTH SAID TRANS GOT HOT AND BURNED UP. NO LOCAL TRANS SHOPS WILL REBUILD THE TRANSMISSION DUE TO REPEAT FAILURES. *TR

Mileage: 86,000

WHILE DRIVING TO WORK IN MY PONTIAC GRAND PRIX GXP ONE MORNING I CAME TO A STOPLIGHT. CAR WAS RUNNING NORMAL. I WENT TO LEAVE THE LIGHT AND THE CAR DID NOT MOVE. THE ENGINE WOULD JUST REV UP. I WAS ALMOST REAR ENDED BECAUSE WHEN THE LIGHT TURNED GREEN I LET OFF THE BRAKE AND PRESSED THE GAS AND I DID NOT MOVE. I THOUGHT I MAY HAVE KNOCKED THE TRANSMISSION INTO NEUTRAL BUT I LOOKED DOWN AND THE CAR WAS IN DRIVE. THIS IS WHEN I REALIZED I WAS THE NEXT VICTIM OF THE GM LS4 4T65E-HD COMBO KIT. I WAS STUCK AT THE LIGHT IN THE MIDDLE MOST LANE. I PUT MY HAZARDS ON.CARS HAD TO GO AROUND ME, AND I COULD HAVE GOTTEN HIT. BEING DEAD IN THE WATER SORT OF SPEAK, I WAITED FOR THE ROAD TO CLEAR AND I CHECKED IF I HAD REVERSE. I DID LUCKILY, AND I WAS ABLE TO BACK MY CAR INTO THE PARKING LOT A HALF A BLOCK BACK. THIS WAS A DANGEROUS SITUATION FOR ANY DRIVER. I HAVE ALWAYS BEEN A GM FAN BUT THIS CAR IS CHANGING MY MIND. IT WOULD NOT BE SO BAD IF GM WOULD TAKE RESPONSIBILITY, AND FIX THEIR DEFECTIVE TRANSMISSION PROBLEM. *TR

Mileage: 96,000

I HAVE A 2006 GRAND PRIX GXP WITH 118K MILES ON IT AND THE TRANSMISSION HAS FAILED AND NEED REBUILDING THE DEALER SHIP TOLD ME TO MAKE A REPORT BECAUSE THIS IS A ONGOING DEFECT. *TR

THE TRANSMISSION IS CONSTANTLY SLIPPING IN AND OUT OF OVERDRIVE. IT IS STILL DOING THIS AFTER A 2ND TRANSMISSION FLUSH. THE FIRST WAS DONE BEFORE 50K MILES. THEN SECOND WAS DONE RECENTLY. THIS IS STILL AN ISSUES. BOTH TIMES THERE WERE NO METAL SHAVINGS FOUND DURING THE CHANGE. *TR

Mileage: 81,000

2006 GRAND PRIX GXP TRANSMISSION. *TR

TRANSMISSION STARTED SLIPPING OVER 70MPH. RPMS BEGAN TO FLUCTUATE SPORADICALLY. BASED ON OTHER POSTS LOOKS LIKE THE TRANNY IS GOING OUT. BOUGHT IT FROM [XXX] 2YRS AGO AND WAS TOLD TRANNY HAD BEEN REPLACED SO I FELT CONFIDENT BUYING THE CAR WITH 90K B/C PONTIACS HAVE HISTORICALLY BEEN GREAT CARS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

Mileage: 127,000

THE TRANSMISSION SLIPS AND BANGS BAD AFTER DRIVING AROUND 65 MPH THEN SLOWING DOWN AND TURNING ON AN OFF RAMP TRANS FLUID TEMP IS ABOUT 195 DEGREES AT TIME OF INCIDENT. THIS SLIP HAPPENS IN LOW GEARS SOMETIMES AS WELL AFTER DRIVING AROUND ON SHORT TRIPS. ALSO, REPLACED GEAR SHIFT SPRAGUE LOCK SOMETHING TWO TIMES ALREADY. ALSO THE AC HEATER FAN MOTOR HAS BURNED OUT ,NOW NEW ONE WORKS INTERMITTENTLY. *TR

Mileage: 110,300

TRANSMISSION FAILURE. TORQUE CONVERTER CLUTCH FAILURE CAUSING THE TRANSMISSION TO FAIL. *TR

Mileage: 79,000

LOOKED AT TRANSMISSION TEMPERATURE GAUGE TO SEE THE TRANS TEMP WAS 208 DEGREES. THE CAR WAS RECALLED FOR A TRANS LINE REPLACEMENT WHICH WAS DONE. THIS DID NOT FIX THE PROBLEM. NOW WHEN CAR IS COLD I FEEL SLIPPAGE WHEN GIVING THE CAR GAS GOING UP AN INCLINE. IF YOU GO TO EDMOUNDS.COM YOU WILL BE ABLE TO SEE THIS IS A COMMON PROBLEM. MANY PEOPLE ARE HAVING THIS PROBLEM. THE TRANS LINE THAT WAS REPLACED HAS A FEW FINS BUILD INTO THE LINE. THIS DOES NOT HELP THE TRANSMISSION STAY ANY COOLER. 208 DEGREES IS WAY TO HOT FOR A TRANSMISSION TO BE RUN AND HOLD UP. IT BURNS UP THIS TORQUE CONVERTER UP THEN TAKES THE TRANSMISSION OUT. PLEASE HELP AS THIS IS COSTLY TO HAVE A TORQUE CONVERTER AND TRANSMISSION REBUILT. I WAS TOLD A TRANS COOLER WOULD FIX THE PROBLEM. THANK YOU *TR

Mileage: 36,000

I HAVE A 2006 PONTIAC GRANDPRIX GXP THAT I PURCHASED NEW AND AS OF 5-28-13 I HAVE DRIVEN ONLY 54000 MILES WHEN ON 5-28-13 AFTER COMING TO A COMPLETE STOP AT A TRAFFIC LIGHT I TURNED RIGHT AND THE CAR ONLY BEGAN TO CRAWL INTO ONCOMING TRAFFIC. THANKFULLY I DIDN'T CAUSE AN ACCIDENT AS THE LEFT LANE WAS OPEN TO SWERVE AROUND ME, BUT NEEDLESS TO SAY THE CARS WHERE BEEPING AND SWERVING TO AVOID ME AS I COULD ONLY GO 5MPH. LATER THAT DAY I DROVE THE CAR SLOWLY TO THE DEALERSHIP JUST FOR THEM TO TELL ME THE TRANSMISSION HAS FAILED. I WOULD THINK IT SHOULD LAST ALOT IF NOT DOUBLE THE 54000 MILES I CURRENTLY HAVE ON THE VEHICLE AND IT WOULD COST ME 3500 TO REPLACE!! AFTER BEING FRUSTRATED AND THINKING WHAT IF THE LEFT LANE WAS NOT OPEN, WHERE WOULD I BE THEN, DOING SOME RESEARCH THERE ARE TONS IF NOT ALL OF THE GXP VERSION OF THE PONTIAC GRANDPRIX WITH THE SAME EXACT ISSUE, HOW COME THERE'S NOT AN RECALL, THIS CAN DEFINITELY CAUSE AN ACCIDENT AS YOU CANNOT ACCELERATE WITH NO PRE WARNING SIGNS, AS I EXPERIENCED A NEAR MISS. *TR

Mileage: 54,000

TL* THE CONTACT OWNED A 2006 PONTIAC GRAND PRIX. THE CONTACT STATED THAT WHENEVER HE DROVE THE VEHICLE, THE TRANSMISSION SLIPPED. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION AND THEY STATED THAT THE TORQUE CONVERTER NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED BUT PROVIDED NO ASSISTANCE. THE FAILURE MILEAGE WAS 70,000.

Mileage: 70,000

AS I'M DRIVING ON THE HIGHWAY AND I REACH A SPEED OF 70 MPH OR HIGHER, THE RPM'S START TO JUMP AROUND AND CAN FEEL THE CAR KICKING IN AND OUT OF OVER DRIVE. AT FIRST IT STARTED DOING IT GOING UP A HILL OR INCLINE ON THE HIGHWAY BUT AS TIME HAS GONE ON THE PROBLEM HAS GOTTEN WORSE AND NOW DOES IT EVEN ON STRAIGHT, FLAT ROADS. I GOT ON EDMONDS WEBSITE AND POSTED THE PROBLEM ON THERE ASKING IF ANYBODY KNOWS WHAT'S WRONG WITH IT AND HOW TO FIX IT. I GOT PEOPLE REPLYING BACK TO ME SAYING THAT IT IS MY TRANSMISSION AND THEY HAVE HAD THE SAME PROBLEM AND GMC WILL NOT HELP THEM PAY FOR OR REPAIR IT. THERE ARE PROBABLY A 100 PEOPLE THAT I KNOW OF ALONE THAT ARE HAVING THE SAME PROBLEM. I THINK THIS SHOULD BE LOOKED INTO, IT COULD BECOME A SAFETY ISSUE AND NOT ONLY THAT, GMC SHOULD BE HELD RESPONSIBLE FOR MAKING AND SELLING DEFECTIVE EQUIPMENT TO THE PUBLIC AND REFUSING TO FIX THE PROBLEM. SOMETHING NEEDS TO BE DONE,BUT NO MATTER WHAT HAPPENS I WILL NEVER BUY ANOTHER GMC VEHICLE!!!!! *TR

I BOUGHT THIS AUTOMOBILE BRAND NEW ($32,000) FROM HALEY PONTIAC IN JUNE OF 2006. WHILE DRIVING WITH MY GRANDCHILDREN IN THE CAR THE TRANSMISSION FAILED COMPLETELY IN TRAFFIC. THE CAR ONLY HAS 86,859 MILE ON IT. I CONTACTED BOTH GM AND GMC AND THEY DENY ANY WRONG DOING OR EVEN PARTIAL REIMBURSEMENT. AFTER DOING RESEARCH ON THE INTERNET I HAVE FOUND OVER 2000 PEOPLE WHO HAD THE SAME ISSUE. GMC KNEW WHEN THEY MADE THIS VEHICLE THAT THE TRANSMISSION WAS NOT COMPATIBLE WITH THE CARS V8 5.3 LITRE ENGINE BUT SOLD IT ANYWAY. ALSO SINCE THEY KNEW THE ISSUES THAT WOULD ARISE THIS MAKE AND MODEL CAME WITHOUT THE 100K POWERTRAIN WARRANTY (WHICH THEY HAD BEFORE AND RESUMED IN 2007). I'M REALLY CURIOUS WITH ALL THE COMPLAINTS WHY HASN'T THIS CAR BEEN RECALLED AND REPAIRED PRIOR TO CONSUMERS HAVING TO PAY OVER $3000 FOR NEW TRANSMISSIONS (TO GMC SERVICE DEPARTMENTS). WHAT WILL IT TAKE FOR SOMEONE TO HOLD THEM ACCOUNTABLE AND TREAT CONSUMERS FAIRLY? DOES IT ACTUALLY TAKE A DEATH FROM THE FAULTY MECHANICAL ISSUE? OR PERHAPS A CLASS ACTION LAWSUIT? I'M NOT CERTAIN BUT I TRULY BELIEVE THAT MY COMPLAINT AS WELL AS ALL THE OTHERS OUT THERE (I'M CERTAIN SOME HAVE ALREADY BEEN SENT TO YOU) SHOULD BE GROUNDS ENOUGH FOR AN INVESTIGATION AS WELL AS A RECALL. I PLAN ON PURSING THIS MATTER BY WRITING TO BOTH THE STATE ATTORNEY OFFICES AS WELL AS THE PRESIDENT OF GM. THANK YOU FOR TAKING THE TIME TO READ MY COMPLAINT. *TR

Mileage: 86,859

4T65E-HD AUTOMATIC TRANSMISSION FAILURE. CAR DOES NOT ENGAGE ANY GEAR TO INCLUDE REVERSE. ACCORDING TO GENERAL MOTORS, THIS TRANSMISSION IS RATED TO HANDLE 280 POUND FEET OF TORQUE. HOWEVER, IT WAS MOUNTED IN A VEHICLE (2006 GRAND PRIX GXP) WHICH BY GENERAL MOTORS' OWN ADMISSION MAKES 323 POUND FEET OF TORQUE. THEREFORE, BY GENERAL MOTORS' OWN ADMISSION, THE TRANSMISSION THEY SELECTED FOR THIS VEHICLE WAS NEVER DESIGNED TO HANDLE THE MOTOR TO WHICH OF WAS MATED. MAX TORQUE FOR THIS VEHICLE OCCURS AT JUST 3800 RPM. IT WOULD SEEM THEN THAT AN INDIVIDUAL WOULD NOT NEED TO BE ENGAGING IN HARD OR ABUSIVE DRIVING TO EXCEED THE DESIGN SPECIFICATION OF THIS TRANSMISSION. *TR

Mileage: 111,542

WE HAVE A 2006 PONTIAC GRAND PRIX GXP AND THE TRANSMISSION STARTED SLIPPING AND SHUDDERING. MY WIFE WAS DRIVING THE CAR TO A SHOP AND IT JUST QUIT AND WOULD NOT GO FORWARD OR REVERSE. WE HAD TO HAVE THE TRANSMISSION REPLACED. $3,000 GONE. I CONTACTED PONTIAC CUSTOMER CARE AND THEY DID NOT HELP US IN ANY WAY. I HAVE READ STORY UPON STORY ABOUT TRANSMISSION FAILURES ON THIS PARTICULAR VEHICLE. PEOPLE HAVE BEEN LEFT STRANDED AND WITHOUT A VEHICLE WHILE REPAIRS WERE DONE TO CORRECT GM'S PROBLEM THAT THEY WILL NOT FIX! IS THERE ANYTHING ANYONE CAN DO TO AT LEAST HELP REIMBURSE THOSE WHO HAVE BEEN BURNT BY GM'S LEMONS? ANY HELP WOULD BE GREATLY APPRECIATED. *TR

GOT MY GXP IN 2-12-10 WITH 41000 MILES ON IT. TRANSMISSION WENT OUT IN 56000 MILES. COST 2500 TO FIX NOW WITH 89000 MILES THE TRANSMISSION IS SLIPPING AGAIN. I LOVED GM CARS AND IF THEY DON'T RECALL THIS SOON. I WILL BE GOING TO DODGE HEMI POWER. *TR

Mileage: 67,000

TRANSMISSION FAILED ON MARCH OF 2012 BAD TORQUE CONVERTER THE WHOLE TRANSMISSION HAD TO BE REBUILT AND JUST FAILED AGAIN ON SEPT 22/2012 LAST REPAIR IN MARCH COST WAS $2800 THIS TRANSMISSION HAS LESS THEN 6000 MILES SINCE BEING REBUILT AND FAILED AGAIN PONTIAC 2006 GRAND PRIX GXP 5.3 ENGINE. *TR

2006 PONTIAC GRAND PRIX GXP. TOTAL TRANSMISSION FAILURE AT 110K. THIS IS A FAMILY VEHICLE WHICH WAS PURCHASED NEW. ALL SERVICE MAINTAINED, NEVER EVEN CLOSE TO BEING ABUSED AND THIS TRANSMISSION SHOULD BE WELL WITHIN ITS LIFE. AS I HAVE READ, THESE TRANSMISSIONS ARE BASICALLY(SUPPOSEDLY) A BEEFED UP VERSION OF THE TRANSMISSION USED IN THE 3.8L MODELS. IT IS SAME AS USED IN THE IMPALA SS, WHERE MANY MANY FAILURES HAVE OCCURRED. COMPLETELY FAILED AT 110K. TOOK INTO DEALERSHIP ON A MONDAY, THEY RAN DIAGNOSTICS, TEST DRIVE IT TWICE COULD NOT FIND ANY ISSUE. VEHICLE TOWED IN 24 HOURS LATER, WITH A COMPLETE TRANS. FAILURE. IT STARTED ALL OF A SUDDEN, WOULD NOT SHIFT PROPERLY, HARD SHIFTS, THEN WOULD SKIP GEARS, THEN WOULD NOT GO INTO REVERSE, THEN WOULD NOT ENGAGE AT ALL. THIS IS A VERY SERIOUS ISSUE THAT DESERVES A RECALL. ONLY REAL OPTION IS TO REPLACE WITH A FACTORY REBUILT TRANSMISSION. OBVIOUSLY GM WILL NOT DO A VOLUNTARY RECALL, THEY ARE MAKING TOO MUCH ON THE SALE OF REBUILT TRANSMISSIONS. *TR

Mileage: 110,000

TL* THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX GXP. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, THE VEHICLE DECREASED SPEED AND LOST POWER. THE VEHICLE WAS INOPERABLE AND NO WARNING LIGHTS WERE ILLUMINATED. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHO DIAGNOSED THAT THE FAILURE WAS WITH THE TRANSMISSION, WHICH WAS NOT SUITABLE FOR THE ENGINE SIZE. THE DEALER WAS NOTIFIED WHO STATED THAT IN ORDER TO DIAGNOSE A TEST ON THE VEHICLE, THE VEHICLE HAD TO BE TOWED TO AN AUTHORIZED DEALER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE WHO FILED A CASE ON THE CONTACT'S BEHALF (CASE NUMBER: 71-1090706145). THE VIN WAS NOT AVAILABLE. THE FAILURE AND CURRENT MILEAGE WAS 85,000.

Mileage: 85,000

THE TRANSMISSION FAILED. WAS TOLD THIS WAS A PROBLEM THAT OCCURS IN GM CARS. SHOULD BE RECALL ON CARS IN TRANSMISSION THAT FAILED. COST $1200 TO REPAIR. *TR

Mileage: 90,000

WHEN TAKING OFF FROM A STOP, THE TRANSMISSION HARSHLY JERKS INTO FIRST GEAR. SOMETIMES WHEN COMING FROM A STOP, IT FEELS THE SAME AS A MANUAL TRANSMISSION - HOLDING THE CLUTCH DOWN. I HAVE HAD A FEW CLOSE CALLS AS THE CAR SOMETIMES FAILS TO GIVE OUT FULL POWER FROM A STOP. I AM AFRAID THAT I WILL GET INTO AN ACCIDENT BECAUSE OF THIS. GM CANNOT FIND ANY PROBLEM. *TR

Mileage: 126,855

THE TRANSMISSION FAILED AND NEEDS TO BE REPLACED. *JS

Mileage: 78,000

I HAVE A 2006 PONTIAC GRAND PRIX GXP, I HAVE HAD ALL THE MAINTENANCE DONE ON THIS CAR SINCE I OWNED IT. THE TRANSMISSION WENT OUT ON THIS CAR AT 80,000 MILES AND FROM WHAT I HAVE BEEN READING THIS HAS BEEN A PROBLEM WITH ALL THE GXP'S THAT HAVE COMEOUT AND GM IS NOT WILLING TO RECALL THIS PROBLEM OR EVEN FIX THE PROBLEM THEY KNOW ABOUT. GM SHOULD TAKE RESPONSIBILITY AND FIX THIS FOR EACH CUSTOMER. I HAVE SEEN WHERE PEOPLE HAVE BOUGHT THE CAR AND AT 39000 MILES THE TRANSMISSION IS SLIPPING. THIS IS VERY POOR CUSTOMER SERVICE BY GM AND THEY SHOULD HAVE TO HAVE ALL THE GXP MODELS RECALLED AND THE TRANSMISSIONS REPLACED. THANK YOU *TR

Mileage: 80,000

2006 PONTIAC GRAND PRIX GXP. 104K MILES. THE TRANSMISSION IS GOING OUT AGAIN. SLIPPAGE IN REVERSE AND DRIVE. THIS IS THE 3RD GM/SERTA TRANSMISSION. THE ORIGINAL STOCK TRANSMISSION FAILED AND 39K MILES. 2ND AT 71K, 3RD AT 88K. CAR IS NOT DRIVEN HARD AND HAS NEVER SEEN THE RACE TRACK. TRANS FLUID AND FILTER CHANGED EVERY 10K MILES. *TR

AUTO TRANSMISSION IS SHIFTING HARD AND SLIPPING. SHIFTS HARD FROM 3 TO 4 AND WILL SLIP JUST DRIVING DOWN ROAD AT ROAD SPEED. GETTING WORSE DAY BY DAY, AND MUCH WORSE WHEN COLD. STARTED AS A WHINNING NOISE ABOUT A MONTH AGO. I HAVE BEEN TOLD BY GM DEALER THAT TRANSMISSION WILL PROBABLY NEED REBUILT. I AM ORIGINAL OWNER, CAR HAS NEVER BEEN DRIVEN HARD. *TR

Mileage: 75,500

BOUGHT A "NICE" USED PONTIAC GRAND PRIX GXP IN 2008 (AN 06 MODEL). THE CAR ONLY HAD AROUND 17,000 MILES ON IT. THIS CAR HAS BEEN THE BIGGEST MONEY PIT EVER. I AM SO DISAPPOINTED WITH THIS VEHICLE. I HAVE PRIDED MYSELF IN BUYING AMERICAN MADE VEHICLES, BUT NOT ANYMORE! FIRST OF ALL, THE TIRE SIZING AND THE PRICE OF THE TIRES,RIDICULOUS! THE POWER STEERING LINE BROKE, AND OF COURSE IT WASN'T THE LINE THAT WAS COVERED UNDER RECALL, THERE HAS ALWAYS BEEN A NOISE IN THE FRONT END, ESPECIALLY GOING AT A SLOWER SPEED AND OVER BUMPS, KIND OF POPPING, I'VE ALWAYS FELT THAT THERE WAS SOMETHING WRONG IN THE FRONT END. IN OCT. 2010, THE HUBS AND BEARINGS WERE REPLACED, THEY WERE STILL UNDER WARRANTY, BUT WE HAD TO PAY A DEDUCTIBLE, WHICH WAS QUITE A BIT, THEN IN JULY 2011, WITH 60,000 SOME ODD MILES ON IT, THE TRACTION CONTROL LIGHT, THE ABS LIGHT CAME ON, TOOK IT TO THE DEALERSHIP, THEY SAY IT'S A SENSOR, IN THE LEFT HUB (THAT WE JUST HAD CHANGED, LESS THAN A YEAR AGO), THE WARRANT HAD RAN OUT ON IT, SO WE PAID ALMOST 500 TO REPLACE THAT, THEN SURPRISE, SURPRISE, IT HAS HAPPENED AGAIN THE LIGHTS ARE BACK ON! ALSO, SOMETIMES WHEN I ACCELERATE AT SAY A STOP SIGN OR STOP LIGHT, THERE'S SORT OF A "GRABBING" AND THE CAR DOESN'T WANT TO GO, LIKE IT COULD BE THE TRANSMISSION SLIPPING. THESE ARE ACTUALLY JUST A FEW OF THE THINGS THAT I'VE HAD GO WRONG,THERE'S BEEN ODDS AND ENDS THINGS THAT OF COURSE HAVE COST A FORTUNE TO FIX, EVERYTHING ON THIS CAR IS...OH, THE TIE ROD END, THAT WAS SOMETHING ELSE THAT HAD TO BE REPLACED...I COULD GO ON AND ON MONEY PIT. I WANT TO GET RID OF IT, BUT IT'S ONE OF THOSE THINGS, I'VE GOT TOO MUCH INVESTED IN IT..I'D NEVER GET OUT OF IT WHAT I NEED..NO WONDER THEY NO LONGER PRODUCE PONTIACS. FROM THE THINGS I'VE READ, IT SEEMS THAT I AM NOT THE ONLY PERSON WHO HAS HAD TROUBLE OUT OF THIS VEHICLE. IT SEEMS AS THOUGH THERE SHOULD HAVE BEEN ALOT MORE RECALLS. *TR

I HAVE A 2006 PONTIAC GRAND PRIX GXP. I STARTED HAVING TRANSMISSION PROBLEMS LAST DECEMBER. THE CAR SHUDDERS HORRIBLY AROUND 50 MPH. HAD THE CAR TO A FEW DIFFERENT GM DEALERSHIPS. ONE CLAIMS THEY DIDN'T FIND ANYTHING WRONG. THE OTHER ONE FELT THE PROBLEM, REPLACED A SOLENOID AND CAR CONTINUED TO DO IT. AT THIS POINT THEY CLAIM THERE IS NOTHING WRONG EVEN THOUGH THE SHUDDER IS STILL THERE. CAR WAS UNDER WARRANTY TIL MARCH. NO LONGER UNDER WARRANTY AND IS GETTING WORSE. I KNOW OF OVER 150 PEOPLE WITH W-BODY V8 GM CARS THAT HAVE EXPERIENCED TRANS. PROBLEMS. WHY HASN'T THERE BEEN A FEDERAL INVESTIGATION???? I GUESS IT MAY BE BECAUSE OF THE GM BAILOUT? NHTSA, PLEASE LAUNCH AN INVESTIGATION AND A RECALL!!!!! I GUESS YOU'LL JUST WAIT UNTIL IT CAUSES MORE ACCIDENTS AND DEATHS! GOOD JOB MORONS!! THANKS FOR LOOKING OUT FOR THE PEOPLE! *TT

WE HAVE A 2006 GRAND PRIX GXP. THE SIGHT AND SOUND OF THIS MACHINE IS WONDERFUL. THE TRANSMISSION ISSUES MAKE ME WANT TO DRIVE THIS CAR UP GM'S, WELL U GET THE PICTURE. IT SLAMS INTO FIRST FROM A STOP, SLIPS WHEN ACCELERATING, AND IT HAS LESS THAN 70,000 MILES ON IT. I HAVE HAD THIS CAR INTO THE DEALER THREE TIMES FOR THE SAME PROBLEM WHILE UNDER WARRANTY. ONE "OVERHAUL" AND TWO DIAGNOSTIC CHECKS LATER THE PROBLEM IS STILL THERE. THE FLUID WAS CHANGED AT 47,000 MILES. I HAVE HEARD IT IS A PRESSURE VALVE PROBLEM BUT THIS FIX WILL BE ON MY DIME, AS IT IS OUT OF WARRANTY NOW. WAY TO GO GM, ANOTHER VICTIM HERE. *TR

I HAVE A 2006 PONTIAC GRAND PRIX GXP WITH THE 5.3L V8 ENGINE. THE CAR HAS LESS THAN 104,000 MILES ON IT AND THE TRANSMISSION DOES NOT ALWAYS ENGAGE FIRST GEAR WHEN ATTEMPTING TO ACCELERATE FROM A STOP. WHEN FIRST GEAR FINALLY ENGAGES IT DOES SO WITH A VERY PHYSICAL BANGING FEELING. ALSO, THE TRANSMISSION SHIFTS EXTREMELY SLOWING FROM 2ND TO 3RD GEAR AT TIMES. THIS IS A MAJOR SAFETY HAZARD WHEN ATTEMPTING TO PULL OUT IN TRAFFIC, IF YOU ARE GIVING YOURSELF ENOUGH TIME TO MAKE A TURN, AND THE TRANSMISSION WILL NOT ENGAGE, AND THEN FORCEFULLY DOES SO, IT COULD CAUSE AN ACCIDENT THAT RESULTS IN INJURY OR EVEN DEATH. I KNOW THAT MY CAR IS ONLY ONE OF VERY MANY W-BODY V8'S THAT HAVE/ARE EXPERIENCING TRANSMISSION PROBLEMS. WE ARE FORCED TO SPEND OUR MONEY AND HURT OUR CREDIT TO FIX A TRANSMISSION THAT SHOULD NEVER HAVE BEEN PUT IN THE CAR TO BEGIN WITH. AMERICAN CARS SHOULD BE BUILT BETTER THAN THIS! IF THE GOVERNMENT WON'T HOLD GM ACCOUNTABLE FOR THIS MESS, MORE CONSUMERS WILL HAVE THE SAME PROBLEMS THAT I AND MANY OTHERS ARE EXPERIENCING. *TR

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

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

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

I WAS JUST INFORMED BY THE DEALERSHIP ON APRIL 3 2010 THAT MY TRANSMISSION NEEDS TO BE REPLACED IN MY 2006 GRAND PRIX, WHICH I PURCHASED NEW. THIS IS A VERY DISTURBING DISCOVERY BEING THAT MY CAR WAS BRAND NEW AT THE TIME OF PURCHASE AND NOW NEEDS AN ENTIRELY NEW TRANSMISSION. THE INCIDENT THAT OCCURRED WHICH PROMPTED ME TO TAKE MY CAR TO THE DEALERSHIP HAPPENED APPX 2 WEEKS AGO WHEN I TRIED TO PRESS THE GAS PEDAL AND THE CAR WOULD NOT ACCELERATE. LUCKILY, I WAS ON A SIDE STREET AND NOT ON A MAJOR HIGHWAY WHICH WOULD HAVE CAUSED SERIOUS INCIDENTS. THIS IS THE ONLY TIME THIS HAS HAPPENED AND I HAVE RECEIVED NO NOTIFICATIONS THROUGH ONSTAR THAT THERE IS A PROBLEM WITH MY TRANSMISSION. SO, I AM CONCERNED ABOUT THIS ISSUE AND WONDERED WHERE I CAN SEEK ASSISTANCE. *TR

TL*THE CONTACT OWNS A 2006 PONTIAC GRAND PRIX. WHILE DRIVING APPROXIMATELY 30 MPH, THE VEHICLE JERKED AND THEN STALLED AT A TRAFFIC LIGHT. SHE SHIFTED THE GEAR INTO PARK IN ORDER TO RESTART THE VEHICLE. AFTERWARDS, THE VEHICLE WOULD NOT ACCELERATE PAST TEN MPH. THE VEHICLE WAS TOWED TO A LOCAL REPAIR SHOP AND THEY STATED THAT THE TRANSMISSION WAS DEFECTIVE. THE VEHICLE WAS REPAIRED. APPROXIMATELY TWO MONTHS LATER, SHE NOTICED A LOUD NOISE AND HER VEHICLE WAS DRIVEN TO A LOCAL REPAIR SHOP. THE MECHANIC INFORMED HER THAT THERE WAS A HOLE IN THE WATER PUMP THAT NEEDED TO BE REPLACED. FOUR MONTHS LATER, THE WINDOWS WOULD NOT ROLL DOWN. THE VEHICLE WAS DRIVEN TO A LOCAL REPAIR SHOP AND THE MECHANIC REVIEWED A DIAGRAM OF THE VEHICLE. THE DIAGRAM STATED THAT THE FUSE FOR THE WINDOW WAS NOT LOCATED IN THE PROPER PLACE. THE WINDOW HAS NOT BEEN REPAIRED. THE DEALER STATED THAT THE FAILURE WAS NOT UNDER WARRANTY. THE MANUFACTURER HAS NOT BEEN NOTIFIED. THE CURRENT MILEAGE WAS 50,000 AND FAILURE MILEAGE WAS 45,000.

APPROX. ONE WEEK OF TRANSMISSION TRYING TO KICK INTO NEXT GEAR, THEN ONE DAY (AFTER ABOUT 4 DAYS OF THIS OCCURRING) TRANSMISSION COMPLETELY DIED. ABLE TO PUT INTO DRIVE BUT TRANS WAS NOT COMMUNICATING WITH WHEELS (PER ONSTAR DIAGNOSTIC REPORT). HAD TO BE TOWED TO DEALER WHO SAID THAT THERE WERE "SEVERAL NOTES ON COMPUTER SYSTEM" AND THAT THE FLUID WAS "BURNT BEYOND RECOGNITION." HAD CAR TOWED TO A DIFFERENT SHOP W/ ASE CERTIFIED MECHANIC WHO SAID THAT WHILE TRANS. FLUID WAS A LITTLE BURNT, WAS NOT THAT BAD. EITHER WAY, A NEW TRANSMISSION IS GOING TO HAVE TO BE PUT INTO CAR AND THERE IS A CHANCE OF THIS HAPPENING AGAIN. PONTIAC/GM IS AWARE OF PROBLEM DUE TO TSB'S BEING PUT OUT FOR PROBLEM, BUT NO RECALL HAS BEEN ISSUED YET. REFUSE TO PURCHASE A 3-4K TRANSMISSION FOR THIS PROBLEM TO PROBABLY HAPPEN AGAIN BEFORE 60K MILES. *TR
