2000 PONTIAC GRAND PRIX Power Train Problems

TRANSMISSION FAILURE AT 180K MILES. CAR WILL NOT SHIFT ON IT OWN I HAVE TO FORCE CAR INTO GEAR BY SPEEDING UP HEARING TRANSMISSION WHINE AND THEN LETTING OFF THE GAS PEDAL SO TRANSMISSION SHIFTS GEARS. THIS IS ON ALL ROAD CONDITIONS. SO MANY COMPLAINTS HAVE BEEN MADE WHY HAS GM NOT ISSUED A RECALL ON THIS MATTER.

Mileage: 180,000

WHILE DRIVING THIS VEHICLE DOWN THE ROAD AT 55MPH, THE VEHICLE WILL JUST CUT OFF FOR NO REASON, THEREBY I LOSE CONTROL OF LL THE VEHICLE SAFETY COMPONETS,HAVING TO TRY AND GET OUT OF TRAFFIC. THIS HAPPENS TO A LOT OF GM VEHICLE MADE IN THIS VEHICLE YEAR. THERE ARE MANY ON THE INTERNET WITH THE SAME VEHICLE DEFECT. THIS IS CLEARLY A GM VEHICLE DEFECT. THIS VEHICLE NEEDS TO BE RECALL AS A PUBLIC SAFETY HAZZARD. MYGM REFERENCE NUMBER IS ( 8-3665783770). SO PLEASE DO THE PUBLIC A SERVICE AND HAVE THIS VEHICLE RECALL , BECAUSE THIS PROBLEM IS A PUBLIC SAFETY HAZZARD. NO ONE MECHANIC SEEN TO BE ABLE TO FIND THE PROBLEM. THIS HAPPENS AFTER THEY SAY MY VEHICLE, SPENT LOTS OF MONEY ,BUT NO ONE SEEMS TO KNOW WHAT CAUSES THIS PROBLEM, INCLUDING GM.

CONTACTED GM TO TELL THEM I HAVE INFORMATION REGARDING ENGINE COMPARTMENT FIRES IN W BODY CARS 1997-2004. THEY DON'T SEEM TO BE INTERESTED.

THERE ARE MANY SAFETY CONCERNS ON THIS VEHICLE. THE FIRST CONCERN IS THE SMOKE THAT COMES FROM UNDER THE HOOD BECAUSE OF THE OIL LEAKING ON THE ENGINE WHILE IN MOTION. TO THE POINT I HAVE HAD TO USE A HOSE TO COOL DOWN THE MOTOR. OIL POURED OUT WITH THE WATER. I HAVE HAD THE PRIOR RECALLS DONE AND STILL HAD LEAKING AFTER THE SO CALLED RECALL WAS DONE IN 2010. I WAS TOLD BY CASTLE PONTIAC (NORTH RIVERSIDE, IL) THERE WAS NO FURTHER REPAIRS THEY COULD OFFER. EVEN THOUGH I SHOWED THEM THE OIL CONTINUING TO LEAK AFTER THE SO CALLED RECALL WAS COMPLETED. THE SECOND CONCERN IS THE HEAD LAMP ASSEMBLY THAT IS FOGGY LOOKING CAUSING THE VEHICLE TO HAVE POOR LIGHTING. THE NEXT CONCERN IS THE SUSPENSION THAT IS LITERALLY FALLING APART. I HAVE ALSO HAD TO HAVE THE HEAD GASKET CHANGED ON THIS VEHICLE AND THE TRANSMISSION HAD TO BE REBUILT. ALSO THE TAIL LAMPS RETAIN WATER EVERY TIME IT RAINS & THE PASSENGER & DRIVERS SIDE DOORS FILL WITH RAIN. LIKE I SAID THERE ARE MANY SAFETY CONCERNS ON THIS VEHICLE. I CAN PROVIDE PHOTOS TO THE CORRECT PARTIES & WOULD BE WILLING TO CONSIDER MY VEHICLE BEING USED TO BE INVESTIGATED TO CREATE REMEDIES FOR THESE SAFETY CONCERNS AS MY SMALL CHILD & MYSELF TRAVEL IN THIS VEHICLE. WHEN I TALKED TO GM CUSTOMER SERVICE TODAY I WAS TOLD THE VEHICLE IS SAFE TO DRIVE YET I AM SURE IF THE OWNER OF GM HAD THIS VEHICLE THEY WOULD NOT DEEM THIS VEHICLE SAFE. THANK YOU IN ADVANCE FOR TAKING TIME TO READ MY CONCERNS. *TR

TL* THE CONTACT OWNS A 2000 PONTIAC GRAND PRIX. THE CONTACT STATED THAT WHILE STARTING THE VEHICLE, THE ENGINE RPMS INCREASED AS THE ENGINE ROARED. THE CONTACT ALSO STATED THAT THE VEHICLE SURGED FORWARD AND JERKED. AS A RESULT, THE BRAKE PEDAL WAS DEPRESSED IN ORDER TO CONTROL THE VEHICLE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO DIAGNOSED THAT THREE UNKNOWN SENSORS FROM THE TRANSMISSION NEEDED TO BE REPLACED. IN ADDITION, THE CONTACT STATED THAT THE STEERING RACK AND PINION BECAME DETACHED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURES. THE APPROXIMATE FAILURE MILEAGE WAS 89,000.

Mileage: 89,000

TL* THE CONTACT OWNS A 2000 PONTIAC GRAND PRIX. THE CONTACT STATED WAS DRIVING APPROXIMATELY 25 MPH WHEN THE VEHICLE BEGAN JERKING ABNORMALLY AS THE VEHICLE ATTEMPTED TO SHIFT GEARS. THE VEHICLE WAS TAKEN TO THE DEALER BUT WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 90,000 AND THE CURRENT MILEAGE WAS 150,000.

THERE HAVE BEEN MORE THAN I CAN COUNT ON BOTH HANDS TO THE INCIDENTS THAT THIS CARE HAS STALLED. IT HAPPENS UNEXPECTEDLY AND I NEVER KNOW WHEN IT IS GOING TO HAPPEN, BUT IT ALWAYS SEEMS TO HAPPEN WHEN I AM IN THE MIDDLE OF TRAFFIC. SO, I HAVE TO PULL OVER AND TRY AND START THE CAR. WHICH IT WILL START THEN SPUTTER AND STALL AND DIE. IT HAS HAD A NEW COMPUTER, 2 NEW FUEL PUMPS, FUEL RESISTOR, FUEL RELAY SWITCHES, STARTER, SUPERCHARGER, 2 FUSE BOXES WHICH ARE A DISCONTINUED PART THAT HAS TO COME FROM AN AUTO WRECKER, AND RECENTLY A WIRE THAT WAS FRAYED BEHIND THE FUSE BOX THAT HAD SOMETHING TO DO WITH THE FUEL SYSTEM. ALL THIS HAS BEEN DONE WITHIN THE LAST 10 MONTHS SINCE WE PURCHASED THE CAR ON PAYMENTS ON JUNE 1, 2009. NEEDLESS TO SAY I AM NOT SURE AS OF THIS LAST REPAIR IF IT HAS CORRECTED THE PROBLEM. MY MAIN CONCERN IS IF I WERE DRIVING ON A WINDY MOUNTAINOUS ROAD WITH NO TURNOUTS AND THE CAR DECIDED IT WANTED TO STALL, WHERE WOULD I GO OR DO. BECAUSE A CAR OR BIG RIG COULD BE COMING AROUND THE TURN AND NOT EVEN KNOW I WAS STOPPED. MY LIFE AND ANY OTHER DRIVERS OR PASSENGERS WOULD BE IN JEOPARDY OF BEING INJURED AND/OR KILLED. THIS CAR TO ME IS VERY UNSAFE AND I AM STUCK WITH PAYMENTS AND DON'T KNOW WHAT TO DO ABOUT THE PROBLEMS WE HAVE HAD OR EVEN IF IT HAS BEEN RESOLVED. *TR

MY TRANSMISSION IN MY CAR WAS LEAK OUT OF THE VENT ON TOP OF THE TRANSMISSION AND MY CAR WAS ON FIRE AND I SEE A RECALL ON THE TRANSMISSION. *TR

I HAVE A 2000 PONTIAC GRAND PRIX GP AND WHEN IT WOULD RUN FOR AWHILE, OR I WOULD DRIVE A LOT IN A DAY, THE TRANSMISSION SEEMED TO SHIFT HARDER. ON THE HIGHWAY IT WOULD BE ESPECIALLY BAD OR FROM A TRAFFIC LIGHT GOING FROM STOPPED TO HIGHWAY SPEED. IT WOULD SHIFT HARD AND SOUNDED TERRIBLE. I TOOK IT TO THE SHOP, AND THEY FOUND OUT THEY WOULD HAVE TO RE-BUILD MY TRANSMISSION! AT A TOTAL COST OF OVER $2500 TO ME! HAD I NOT TAKEN MY VEHICLE TO THE SHOP, MY TRANSMISSION WOULD HAVE EVENTUALLY FAILED, AND COULD HAVE LED TO A MORE SERIOUS ACCIDENT AND A MORE COSTLY REPAIR. *TR

I OWN A 2000 PONTIAC GRAN PRIX GT. EVERYTIME I DRIVE IT, THE SERVICE ENGINE LIGHT COMES ON AND THE TRANSMISSION SHIFTS VERY "HARD". THIS ONLY CAN BE CORRECTED IF I PULL OFF THE SIDE OF THE ROAD (WHICH CAN BE VERY DANGEROUS) AND WAIT SEVERAL MINUTES AND RESTART THE CAR. WHEN THIS HAPPENS THE RPM'S STARTS TO "REV" UP AND DOWN CONSTANTLY WHETHER WHILE DRIVING OR SETTING WHILE IN PARK. I HAVE COME CLOSE TO SEVERAL WRECKS WHEN THIS HAPPENS, ESPECIALLY WHEN THE ROADS ARE WET. BEFORE YOU KNOW IT YOU APPLY THE BREAKS ENOUGH TO SLOW DOWN FOR THE CAR IN FRONT OF YOU AND THEN THE RPM "REV" UP AND YOU ALMOST HIT THE CAR IN FRONT OF YOU IN THE REAR. I HAVE READ SEVERAL SIMILAR REPORTS AND I REALLY DON'T UNDERSTAND WITH ALL THE COMPLAINTS THIS CANNOT BE RECALLED TO FIX THIS. *TR

I OWN A 2000 PONTIAC GRAND PRIX GT ABOUT 2YRS. AGO MY TRANSMISSION FAILED ON ME. MY PROBLEM WAS DIAGNOSED BY A ASE CERTIFIED MASTER MECHANIC. I WROTE A LETTER TO GM ABOUT THIS PROBLEM,WHICH WASN'T MY ONLY GM TRANSMISSION I HAVE HAD REPLACED WITHIN A 5 YEAR TIME FRAME .I ALSO HAD TO REPLACE ONE IN A 1990 CHEVY CAVALIER Z24 THAT WAS ONLY ABOUT 9 YEARS OLD AT THE TIME AND I ALSO HAD TO REPLACE THE FUEL INJECTORS ON THAT AS WELL BUT THAT IS A WHOLE OTHER STORY. I CALLED DEALERSHIPS TO GET THE PROPER ADDRESS OF WHERE I COULD SEND MY LETTER OF DISSATISFACTION WITH GM, AND IT WAS COMPLETELY IGNORED!I DIDN'T ASK GM TO PAY FOR THE WHOLE TRANSMISSION REPLACEMENT,JUST TO MEET ME HALF WAY AND HELP A REGULAR GUY GET TO AND FROM WORK WITH A DEPENDABLE VEHICLE,TAKE CARE OF HIS FAMILY AND NOT BE HIT WITH A 2200.00 BILL THAT I AM STILL PAYING ON BECAUSE I HAD TO PUT IT ON A CREDIT CARD AND ALSO GET CHARGED INTEREST ON TOP OF THAT. GM,FORD AND CHRYSLER WONDER WHY THEY ARE LOSING THE BATTLE TO FOREIGN CARS? MY PERSONAL OPINION IS THIS SIMPLE:THEY HAVE HIGHER TOLERANCES WHEN THEIR VEHICLES ARE PUT TOGETHER RESULTING IN LESS MECHANICAL FAILURES. DON'T GET ME WRONG WHEN I FIRST ENTERED THE CAR BUYING MARKET, I LOVED AND ONLY, BOUGHT AMERICAN CARS, BUT OVER THE YEARS MY OPINION HAS BEEN SWAYED. I ALSO FEEL THAT BECAUSE MY PROBLEM WASN'T DIAGNOSED BY A MECHANIC WHO WAS EMPLOYED BY GM,THAT WAS JUST ANOTHER REASON MY LETTER WENT UNANSWERED. *JB

MY 2000 PONTIAC GRAND PRIX HAS HAD TWO FAILURES OF THE PRESSURE CONTROL SOLENOID AND THE CORRESPONDING VALVE BODY, CAUSING MY CAR TO UNEXPECTEDLY SURGE WHEN ACCELERATING. THE DEALERSHIP KEPT BOTH OLD PARTS, BUT THIS SEEMS TO BE HAPPENING TO MANY PEOPLE SO IT SHOULDN'T BE HARD TO FIND ONE. BOTH REPAIRS WERE COVERED UNDER WARRANTIES. THE FIRST ONE WAS REPLACED AT 32,000 MILES, AND THE SECOND AT 73,000 MILES. I HOPE NO ONE HAS AN ACCIDENT WHEN THIS HAPPENS, I KNOW I ALMOST DID, THE FIRST TIME IT HAPPENED I WAS SO SURPRISED I NEARLY RAN INTO ANOTHER CAR.*JB

DT: WHEN PLACING THE KEY IN THE IGNITION, THE ENGINE WILL START, BUT WHEN TRYING TO RELEASE THE KEY FROM THE IGNITION IT LOCKS. THIS RESULTS IN THE BATTERY RUNNING DOWN AND THE INABILITY TO THE LOCK CAR. TOOK CAR TO A DEALER IN APRIL 2004 AND HAD PROBLEM REPAIRED. THE DEALERSHIP REPLACED THE GEAR SHIFT INDICATOR ALONG WITH THE IGNITION LOCK RELEASE. A WEEK AGO THE EXACT SAME PROBLEM OCCURRED AGAIN. DID NOT HAVE ANY REPAIRS SINCE DISCOVERING THIS.*AK

Mileage: 80,000

THE VEHICLE HAS HAD A PROBLEM WITH THE TRANSMISSION SLIPPING OFF AND ON FOR ABOUT A YEAR. AAMCO COULDN'T DETECT A PROBLEM WITHOUT A CHECK ENGINE LIGHT. THE LIGHT CAME ON IN FEBRUARY 2005. THE VEHICLE NEEDED A SENSOR REPLACED AND THERE WAS A ERROR ON THE TRANSMISSION ALSO. A COMPLETE FLUID REPLACEMENT WAS DONE AND A CONDITIONER ADDED HOPING THAT THIS WOULD CURE THE PROBLEM. ON JUNE 1 THE LIGHT CAME ON AND THE SLIPPING OCCURRED AGAIN. IT LOST MERGING POWER ON THE BALTIMORE BELTWAY AND I BROUGHT IT INTO AAMCO FOR AN ANALYSIS. THEY CONCLUDED THAT THE TORQUE CONVERTER IS STUCK AS WELL AS SOME ADDITIONAL ITEM. THE CAR IS A 2000 PONTIAC GRAND PRIX WITH 83,000 MILES ON IT. I BELIEVE THAT THE POWER TRAIN WARRANTY ONLY COVERS THE VEHICLE FOR 80,000 MILES. SINCE THIS HAS BEEN AN ONGOING PROBLEM PRIOR TO THE 80,000, I WOULD LIKE TO THINK THAT GM WOULD ASSUME SOME LIABILITY FOR THE REPAIR ($1900.00). FROM SOME OF THE COMPLAINTS ON YOUR WEBSITE, I BELIEVE THAT THE TRANSMISSION IN THIS VEHICLE MAY BE DEFECTIVE IN SOME WAY.

Mileage: 83,450

THE TRANSMISSION IN MY 2000 PONTIAC GRAND PRIX GT HAS BEEN SHIFTING WITH A "HARD" SHIFT AFTER ABOUT 30-40 MINUTES OF TRAVEL. THIS USUALLY HAPPENS AFTER I HAVE COME TO A FULL STOP OR AFTER A SLOW TURN AS IF WHEN COMING OFF THE FREEWAY AND MERGING INTO TRAFFIC. THIS GOES AWAY AFTER I TURN THE MOTOR OFF, WAIT FOR APPROX. 10 MIN. AND RESTART THE MOTOR AND AT TIMES DOES NOT RETURN UNTIL I TRAVEL FOR A FEW MILES. *AK

Mileage: 125,000

THE TRANSMISSION IN MY 2000 PONTIAC GRAND PRIX STARTED SHIFTING FUNNY THEN IT WOULD SHIFT FINE AFTER SHUTTING IT OFF AND RESTARTING AFTER THIS HAPPENING A FEW TIMES I TOOK IT TO A TRANS SHOP AND THEY INFORMED ME THAT THIS A COMMON PROBLEM ON GM CARS AND THAT THE REPAIR WOULD BE $600-$700 THE CAR ONLY HAS 60,000 MILES.AFTER TALKING TO A PERSON FROM GM HE ADMITED THAT THEY HAD A BAD SUPPLIER OF PARTS FROM 1998-2000 AND THAT IF IT WAS UNDER WARRANTY THEY WOULD HAVE FIXED IT FOR FREE.WELL ITS NOT UNDER WARRANTY AND IM STUCK WITH A $600+ BILL TO FIX A PROBLEM THEY WHERE AWARE OF.THE GUY AT THE TRANS SHOP SAYS HE SEES ABOUT 3-4 OF THESE A WEEK.ALSO IF YOU DO ANY SEARCHES AND READING ON THE 4T65E TRANS YOU WILL FIND ALOT OF PEOPLE COMPLAINING OF THE SAME THING.TO FIX THIS TRANS THEY PULL IT ALMOST APART AND PUT NEW PRESSURE SOLENOIDS IN IT.*AK

I HAVE THE SAME PROBLEM AS JUST ABOUT EVERYBODY ELSE. MY TRANSMISSION HAS LOST OVERDRIVE AND SHIFTS ERRATICALLY. WHEN I AM AT 60 MPH MY RPMS ARE AT 3 AND1/2 !!! I AM READY TO START A CLASS ACTION LAWSUIT AFTER SEEING THE SAME PROBLEMS ON SO MANY CARS *NM

I WANTED TO MAKE YOU AWARE OF A POTENTIAL SAFETY HAZARD ON THE ROAD WITHIN GM VEHICLES. I ALREADY HAD TWO MAJOR TRANSMISSION REPAIRS ON CAR WITH ABOUT 75,000 MILES. THE FIRST PROBLEM OCCURRED WHEN MY CAR WAS BARELY OUT OF WARRANTY, AT APPROXIMATELY 42,000 MILES. THE TRANSMISSION STOPPED SHIFTING INTO OVERDRIVE. THIS FORCED US TO DRIVE 150 MILES BACK HOME ONLY GOING 40 MPH. THIS WEEKEND, I EXPERIENCED A TOTAL TRANSMISSION FAILURE. WHILE DRIVING ON THE FREEWAY, MY CAR SUDDENLY MADE A LOUD NOISE AND DECELERATED FROM 65 MPH TO AROUND 35 MPH IMMEDIATELY. THE DEFECT ALMOST CAUSED A MAJOR ACCIDENT AS WE WERE IN THE HIGH SPEED LANE. WHEN WE GOT OFF THE FREEWAY AND PARKED, WE REALIZED THE CAR WOULD NO LONGER GO IN REVERSE. I SHELLED OUT ALMOST $1,800 ON A REBUILT TRANSMISSION. MY REPAIR SHOP INFORMED ME THAT THEY ARE REGULARLY DOING REBUILDS ON THE SAME GM TRANSMISSION THAT IS IN MY PONTIAC. A COMMON SIGN ON THE FAILURE IS THE LOSS OF THE REVERSE GEAR. IN FACT, PARMA TRANSMISSION HAD DONE THREE ALONE DURING THE WEEK MY CAR WAS IN THE SHOP. I AM SHOCKED THAT GM WOULD INSTALL SUCH A FAULTY AND DANGEROUS PIECE OF MACHINERY ON ITS VEHICLES. I HARDLY FIND IT COINCIDENTAL THAT ALL OF THESE OWNERS ARE HAVING THE SAME PROBLEMS WITH YOUR CARS. PLEASE BE SURE NOT TO GROUP THIS PROBLEM JUST WITH PONTIAC. THEY PUT THE SAME TRANSMISSION IN MANY OF THEIR CARS, SO YOU WILL NEED TO FIGURE OUT ALL THE VEHICLES THAT ARE UNDER THIS PART NUMBER. I DID NOT KEEP THE OLD PARTS, BUT I AM SURE THE SHOP I WORK WITH WOULD BE ABLE TO START SAVING ALL OF THE DESTROYED COMPONENTS THAT THEY CONTINUALLY REPAIR. *NM

Mileage: 76,000

I AM HAVING THE SAME PROBLEM AS ODI ID# 10070342. TOOK TO DEALERSHIP TODAY AND WAS TOLD SHIFTER ASSEMBLY NEEDS REPLACED AT A COST OF $375. *AK

CHECK ENGINE LIGHT CAME ONE. CAR WAS SHIFTING HARD AND "JERKING." PULLED IN TO A NEARBY REPAIR SHOP AND TWO DIAGNOSTIC CODES WERE FOUND RELATING TO THE TRANSMISSION. ONE RELATED TO THE PRESSURE CONTROL SOLENOID AND THE OTHER "LONG SHIFT W/ MAX ADAPT". THEY SUGGESTED I TAKE IT TO A TRANSMISSION SHOP. I THEN TOOK THE VEHICLE TO MY REGULAR MECHANIC, HE COULD NOT DUPLICATE THE PROBLEM NOR COULD HE FIND ANYTHING WRONG AT THAT TIME. HE ALSO SUGGESTED I TAKE IT TO A SHOP SPECIALIZING IN TRANSMISSIONS. I DID. THEY ALSO COULD NOT DUPLCATE THE PROBLEM OR FIND ANYTHING OTHER THAN METAL SHAVINGS IN THE PAN. THEY SUGGESTED I HAVE THE TRANSMISSION COMPLETELY REBUILT AT A COST OF OVER $2,100.00.*AK

TRANSMISSION WAS REBUILT/REPLACED AT 27,000 MILES (THIS WAS UNDER WARRANTY). NOW AT 86,000 MILES TRANSMISSION HAD TO BE REBUILT DUE TO A GASKET BLOW THAT CAUSED ALL THE FLUID TO LEAK OUT WHICH THEN CAUSED INTERNAL PROBLEMS. THIS IS A VERY COSTLY DEFECT THAT I FEEL MAY HAVE TO DO WITH A DEFECT FROM THE MANUFACTURER. A $28,000 CAR SHOULD NOT HAVE A MAJOR DEFECT OF THIS MAGNITUDE TWICE BEFORE IT EVEN REACHES 100,000 MILE. THIS SHOULD BE INVESTIGATED BY GM BECAUSE I AM NOW SEEING THAT I AM NOT THE ONLY ONE WITH THIS PROBLEM. GM SHOULD HAVE TO PAY FOR THIS EXPENSIVE REPAIR. *LA

Mileage: 27,000

CAR HAS ERRATIC SHIFTING, JERKS WHEN ACCELERATING. TAKEN TO DEALERSHIP AND DIAGNOSED AS PRESSURE CONTROL SOLENOID. WHEN THE TRANS PAN WAS TAKEN OFF THERE WAS SIGNIFICANT AMOUNTS OF METAL SHAVINGS. THE TRASNMISSION WAS THEN TAKEN APART AND FOUND THAT THE CLUTCH AND MANY GEARS WERE DAMAGED BECAUSE OF THE METAL. GM WAS CONTACTED FOR ASSISTANCE AND THEY SAID THEY WOULDN'T GUARANTEE THERE DEFECTIVE PARTS BECAUSE THEY CAN NOT DETERMINE HOW THE PREVIOUS OWNER TOOK CARE OF THE CAR.*AK

MAIN COMPLAINT: GM IS AWARE THAT THEIR GM HYDRA-MATIC 4T65-E TRANSMISSION HAS A DEFECTIVE PART, YET THEY LEAVE IT TO CONSUMERS TO COVER THE COST OF HANDLING THE PROBLEM. SPECIFICALLY, MY 2000 GRAND PRIX GT (WITH ONLY 64,000 MILES ON IT) STARTED UPSHIFTING HARD A FEW DAYS AGO FROM 1ST TO 2ND GEAR AND I HEAR METALLIC GRINDING NOISES FROM UNDERNEATH THE CAR WHEN SHIFTING FROM 1ST TO 2ND WHILE THE CAR IS STILL WARMING UP. HAVING PERFORMED ALL OF THE NECESSARY MAINTENANCE OVER THE YEARS, I AM ANGERED TO LEARN THAT I WILL HAVE TO FORK OVER APPROXIMATELY $600 TO REPAIR A MANUFACTURER'S DEFECT ON A CAR THAT I AM STILL PAYING FOR. I'VE READ OF OTHER PEOPLE HAVING TO PAY SIGNIFICANTLY MORE TO FIX THIS PROBLEM ON THEIR CARS. RECENTLY, GM REPAIRED A COOLANT LEAK AT NO COST TO CONSUMERS BECAUSE IT WAS DEEMED A DEFECT. I HAD ALREADY EXPERIENCED "LOW ENGINE COOLANT" WARNINGS FROM MY CAR AND WAS RELIEVED TO RECEIVE THE RECALL LETTER OFFERING TO FIX THE PROBLEM FOR FREE. OF COURSE, THAT REPAIR TOOK 15 MINUTES - GM DIDN'T MIND PICKING UP THE COST FOR THAT DEFECT. MY CURRENT PROBLEM WILL REQUIRE SEVERAL HOURS OF TRANSAXLE WORK AND GM HAS CONVENIENTLY STUCK ME WITH THE COST OF THIS WORK. I ALSO WONDER WHY CONSUMERS ARE NOT BEING ALERTED TO THIS PROBLEM. SOME PEOPLE MAY NOT NOTICE OR MAY CHOOSE TO IGNORE THE SYMPTOMS THAT I NOTICED UNTIL THE OTHER DAY UNTIL THEY HAVE A CATASTROPHIC PROBLEM AND HAVE TO PAY THOUSANDS TO REPAIR THEIR TRANSAXLE. IT SEEMS IRRESPONSIBLE TO ME THAT GM ONLY ISSUED THIS INFORMATION AS A SERVICE BULLETIN TO MECHANICS. OTHER MINOR COMPLAINTS: MY CAR INTERMITTENTLY HAD TROUBLE STARTING AROUND 45000 MILES. TWO MECHANICS CHECKED IT AND FOUND NOTHING WRONG. MY KID BROTHER FOUND A LOOSE WIRE COMING FROM THE BATTERY AND QUICKLY FIXED THE PROBLEM. CURRENTLY, I HAVE LOST LEVELS 1-3 OF 5 FOR MY HEATING/COOLING FAN, MY WINDSHIELD WIPER FLUID PUMP HAS STOPPED WORKING AND THE LOCK ON MY TRUNK IS INOPERABLE. I'M NOT CARELESS - THESE MATERIALS SHOULD HAVE LASTED MUCH LONGER. *LA

2000 PONTIAC GRAND PRIX GTP HAS 42,000 MILES. WE PURCHASED THIS VEHICLE NEW IN JANUARY OF 2000. NO SIGN OF TRANSMISSION FAILURE. GOING FROM A STOP LOUD CLANKING NOISE, CAR JERKED 3 OR 4 TIMES. 5 MINUTES LATER AFTER ANOTHER STOP SIGN THE CAR DID THE SAME THING AGAIN. I STOPPED TO A REPAIR STATION, WHEN I PUT THE CAR IN PARK IT MAKES AN AWFUL GRINDING NOISE WHILE IDLING. THE SERVICE TECHNICIAN TOOK THE CAR FOR A DRIVE AND SAID TO GET IT TO A GM DEALER BECAUSE THE TRANSMISSION IS GOING. I WAS TOLD THIS SHOULD NOT HAVE HAPPENED ON A CAR THAT ONLY HAS 42,000 MILES ON IT. AS I AM LOOKING THROUGH THE CONSUMER AFFAIRS COMPLAINT DATA BASE I AM SEEING 9 COMPLAINTS THAT ARE QUITE SIMILAR. HOW MANY COMPLAINTS DOES IT TAKE TILL THIS TRANSMISSION PROBLEM IS RECALLED? I PAID $27,000.00 FOR MY CAR 3 1/2 YEARS AGO AND SHOULD NOT HAVE TO PUT $2,000.00 INTO IT ALREADY. I PURCHASE NEW CARS SIMPLY BECAUSE OF FEELING SECURE KNOWING THAT I TAKE CARE OF MY CARS WITH REGULAR OIL CHANGES AND MAINTENANCE AND WOULD NOT HAVE TO WORRY ABOUT ANY MAJOR REPAIRS. I WOULD LIKE THIS RESOLVED BY GM REPAIRING MY VEHICLE AT THEIR EXPENSE. *LA

I HAVE A PONTIAC GRAND PRIX GT, MY SERVICE ENGINE SOON LIGHT CONTINOUSLY COMES ON. I WENT TO THE DEALERSHIP AND THEY PUT THE CAR ON THE COMPUTER AND SAID THAT THE WIRES TO THE HARNESS WERE BROKEN. I DON'T UNDERSTAND HOW THE WIRES TO THE HARNESS COULD BE BROKEN BECAUSE IN ORDER TO GET TO THE WIRES YOU MUST TAKE OFF THREE PARTS.THEY ALSO TOLD ME I HAD A LEAK IN THE INTAKE MANIFOLD AT THE TOP OF THE ENGINE. THE MECHANIC CHANGED THE GASKET AND CHARGED ME $270 PLUS $50 FOR PARTS AND PAYED $360 FOR THE LABOR FOR THE WIRES OF THE HARNESS. THE LIGHT TURNED OFF, THEN THE NEXT DAY THE LIGHT REAPPEARED. I WENT BACK TO THE DEALERSHIP AND THE SAME CODE CAME UP WHEN IT WAS PLACED BACK ON THE COMPUTER (R442), ON THAT DAY THEY SAID THE GAS CAP WAS LEAKING AND HAD TO BE CHANGED. AT THAT MOMENT THE LIGHT WENT OFF! THEN THE NEXT DAY THE LIGHT CAME BACK ON ONCE AGAIN!!! NOW THIS IS THE THIRD TIME I'VE BEEN TO THE DEALERSHIP WITH THE SAME CODE (R442) THEY TOLD ME THEY DON'T KNOW WHAT THE PROBLEM IS. IF THEY CAN'T FIND THE PROBLEM WHY DO I HAVE TO PAY FOR THE PREVIOUS PROBLEMS IF THEY CAN'T EVEN FIND THE PROBLEM. THE WILL NOT HELP ME AND SINCE THESE PROBLEMS OCCURED RIGHT AFTER THE WARRANTY, THEY TOLD ME THAT I HAVE TO PAY FOR ALL THE WORK THEY THAT DO, EVEN IF THEY JUST PUT THE CAR ON THE COMPUTER. $90 AN HOUR! I'VE CALLED CUSTOMER SERVICE REPEATEDLY AND SAY THAT CAN'T DO ANYTHING FOR ME BECAUSE THE DEALERSHIP WILL NOT WORK WITH ME! THEY ARE ALSO FINDING A TRANSMISSION CODE 1811 THEY SAY THEY DON'T FIX TRANSMISSIONS!! WHAT DO I DO??? THE LIGHT WILL NOT TURN OFF AND I'M WORRIED FOR MY SAFTEY! PLEASE HELP!

THE OVER DRIVE FAILED AND ONE WEEK LATER THE ANTIFREEZE LEAKED, THE DEALER REPLACED THE INTAKE MANIFOLD. *JB
