AT 51000 MILES THE 3.4L ENGINE HAD LOWER INTAKE GASKET FAILURE IN WHICH THE DEX-COOL ANTI FREEZE DUMPED INTO THE CRANKCASE MIXING WITH THE OIL. THIS ONLY HAD ONE WARNING A COUPLE MONTHS EARLIER AS THE LOW COOLANT LIGHT CAME ON AND I ADDED 1/2 GALLON DEX-COOL WITH NO SIGNS OF LEAKAGE. NEXT TIME IT HAPPENED WAS WHEN MY WIFE WAS TAKING DAUGHTER TO SCHOOL AND TEMP. LIGHT CAME ON. VAN WAS NOT DRIVEN OVER 2 MILES TO DEALER, AS LIGHT WENT OUT. DEALER SAID EXTREME MIXTURE IN BOTH CRANKCASE AND RADIATOR. RECOMMENDED REPLACE RADIATOR, WATERPUMP, INTAKE GASKETS, FLUSH BOTH SYSTEMS AT A COST OF 1500 NOT TO BE APPLIED TOWARD ENGINE REPLACEMENT IF FAILURE ON START UP. DEALER HAD JUST HAD VAN IN WEEK BEFORE FOR CHECK ENGINE LIGHT AND STEERING RECALL AND FOUND NOTHING WRONG !!!! WE TRADED IT IN AT A LOSS AS I CHECKED INTO THE PROBLEM AND LEARNED ABOUT THOUSANDS OF OTHER OWNERS WITH SAME PROBLEMS WITH TOTAL ENGINE FAILURES AFTER REPAIRS MADE. WE LOST OVER $3000 EQUITY BETWEEN WHAT TRADE VALUE WOULD HAVE BEEN IF NO PROBLEM WITH ENGINE AND LETTING DEALER FIX PROBLEM AFTER TRADE. VAN HAD MANY PROBLEMS SINCE WE BOUGHT IT NEW BUT WE ALWAYS HAD THEM FIXED AND WAS WELL MAINTAINED. LOOKED NEW WHEN WE TRADED WITH ONLY 50,000 MILES. PAINT ON HOOD BLISTERED TWICE, STEERING / BRAKES WOBBLED SINCE NEW AT VARYNG SPEEDS, ALWAYS HAD TICKING SOUND IN ENGINE DEALER SAID WAS "NORMAL", REAR SEATS WOULD JAMB UP IF YOU TRIED TO REMOVE, WIPER ARMS FAILED TWICE, SERPENTINE BELT TENSIONER BROKE OFF ON ENGINE START UP IN DEC. 2002. COST $375 WITH TOWING, POWER WINDOW SWITCH FAILED IN DOWN POSITION AT REPLACEMENT COST OF ABOUT $175. ENGINE UNDER WARRANTY WHEN IT HAD A SEVERE GAS SMELL THAT NEARLY CAUSED A FIRE IN ABOUT 1999. THEY KEPT IT A WEEK AND NEVER SAID WHAT THE PROBLEM WAS. THEY HAD JUST WORKED ON IT FOR TICKING SOUND. (PROBABLY INTAKE GASKETS THEN ALSO). GM WAS NO HELP AFTER WARRANTY WAS UP.

ENGINE FAILURE DUE TO LEAKING INTAKE MAIFOLD GASKET ON 3.4L ENGINE. ENGINE WAS METICULOUSLY MAINTAINED TO THAT POINT, WITH ALL SERVICE RECEIPTS TO PROVE THAT FACT. NO PERVIOUS COOLANT LEAKAGE WAS NOTED BEFORE THE PROBLEM. ENGINE BEGAN MAKING SEVERE KNOCKING NOISES WHILE DRIVING IN MOUNTAINS OF WYOMING. SERVICE TECH AT LARAMIE GM AUTO CENTER SAID THAT THE ENGING WAS LOSING OIL PRESSURE AND CONSUMING (LOSING) COOLANT. COOLANT LEAKED INTO THE INTAKE MAINFOLD THROUGH THE FAULTY INTAKE MAINFOLD GASKET. I HAD THE REPAIR DONE, AND NOW 28,000 INTO THE NEW ENGINE, I AM HEARING VARIOUS ENGINE NOISES AGAIN. WILL GO TO NEW LOCAL DEALER FOR ANALYSIS. GM SHOULD REPAY ME FOR THIS--THEY WILL NOT ADMIT ANY RESPONSIBILITY FOR THIS PROBLEM, ONLY OFFERING A DISCOUNT ON A NEW GM CAR. I AM STILL PAYING ON THIS VEHICLE, BECAUSE THE MONEY THAT WOULD HAVE GONE INTO PAYMENTS WENT TOWARD THE NEW ENGINE AT 67,950 MILES. DRIVER'S SIDE POWER WINDOW REGULATOR HAS ALSO FAILED. $650 ESTIMATE TO REPLACE IT. NUMEROUS OTHER PROBLEMS WITH THIS CAR--MANY HAVE BEEN REPAIRED THROUGH RECALLS. THE ENGINE ISSUE SHOULD BE A RECALL AS WELL, OR A CLASS ACTION SHOULD BE STARTED.

THE TRANSMISSION WENT OUT IN MAY OF THIS YEAR AND NOW THE ENGINE. VAN WAS RUNNING HOT, WE REPLACED THE THERMOSTAT, WATER PUMP, OXYGEN SENSOR, MAIN RADIATOR HOSE AND FLUSHED RADIATOR, AND PURCHASED A NEW RADIATOR CAP. IT IS STILL RUNNING HOT. IT HAS A BLOWN HEAD GASKET, AND A WARPED HEAD, NO TELLING WHAT THIS WILL COST.

OUR 97 PONTIAC TRANSPORT WAS FINE UNTIL LAST YEAR. NEW TRANSMISSION (70,000 MILES, O.K.) THEN A FEW MONTHS LATER IT BEGAN OVERHEATING--NEW THERMOSTAT, WHICH WORKED FOR A FEW WEEKS, THEN NEW RADIATOR, WHICH WORKED FOR A FEW WEEKS, THEN, WHEN THE MECHANIC SAID IT PROBABLY NEEDED A HEAD GASKET ($2000 OR MORE) WE DECIDED TO GET RID OF IT. BUT WE WERE NOT EVEN ABLE TO USE IT AS A TRADE IN, BECAUSE IT OVERHEATED SO BADLY. THE ELECTRICAL SYSTEM HAD ALWAYS BEEN QUIRKY, BUT LIVABLE (I.E. THE GAS GAUGE HAD NEVER WORKED, THE WINDOWS WERE VERY SLOW AND THE CELL PHONE PLUGS NEVER WORKED) I CALLED THE DEALER (PERUZZI, IN LANGHORNE, PA) BUT, OF COURSE, IT WAS NOT THEIR PROBLEM. THE MECHANIC TOLD US THAT GM WAS USING A NEW COOLANT IN THEIR 97'S WHICH BECAME PROBLEMATIC AS IT AGED--HE THOUGHT THAT MIGHT HAVE BEEN THE ORIGINAL SOURCE OF THE PROBLEM, BUT ACKNOWLEDGED THAT GM HAS NOT ADMITTED TO ANY ERROR. WE WERE THE ORIGINAL OWNERS AND ALWAYS MAINTAINED THE CAR PROPERLY, FROM DAY ONE. THE MECHANIC IS A PERSONAL FRIEND, AND HAS AN EXCELLENT REPUTATION. THE CAR WAS SOLD FOR JUNK. IT'S VALUE, ACCORDING TO EDMUNDS.COM, WAS ABOUT $6000/7000 .

IF THERE WOULD HAVE BEEN PEOPLE OR OTHER CARS IN MY WAY THIS COULD HAVE TURNED VERY BAD. ALL THE GM DEALERS SAY THAT THIS IS A COMMON PROBLEM. WHEN I CALL GM THEY SAY THEY NEVER HEARD ABOUT IT. SOMETHING NEEDS TO BE DONE NOW ABOUT THIS PROBLEM. THANK YOU , SCOTT EGGEBRECHT

Official recalls
5Dec 22, 2004
ON CERTAIN MINIVANS EQUIPPED WITH SECOND-ROW BUCKET SEATS OR CAPTAIN'S CHAIRS AND A POWER SLIDING DOOR ON THE PASSENGER SIDE OF THE VEHICLE, A PASSENGER USING THE INTERIOR HANDLE TO OPEN THE POWER SLIDING DOOR COULD BE INJURED.
Consequence & remedy
Consequence: IF A PASSENGER USES THE INTERIOR HANDLE TO OPEN THE POWER SLIDING DOOR AND HOLDS ONTO THE HANDLE WHILE IT IS BEING OPENED BY THE MOTOR, THE PASSENGER'S ARM MAY BE PUSHED INTO THE SEAT BACK OR ARMREST AND A WRIST OR LOWER ARM INJURY MAY RESULT.
Remedy: DEALERS WILL REPLACE THE POWER SLIDING DOOR INTERIOR HANDLE ON THE PASSENGER-SIDE. IF THE VEHICLE IS EQUIPPED WITH A POWER OR MANUAL SLIDING DOOR ON THE DRIVER-SIDE, THE INTERIOR HANDLE WILL ALSO BE REPLACED FOR APPEARANCE REASONS. NOTE: BEFORE THE VEHICLE IS SERVICED, GM ADVISES OWNERS TO NOT USE THE INTERIOR DOOR HANDLE TO OPEN THE DOOR. THE DRIVER CAN OPEN AND CLOSE THE DOOR FROM SWITCHES AT THE DRIVER'S POSITION OR BY USING THE REMOTE KEY FOB. THE DRIVER SHOULD TELL PASSENGERS TO USE THE SWITCH LOCATED IN FRONT OF THE DOOR TO OPEN OR CLOSE IT. THE DRIVER SHOULD USE THE OVERRIDE SWITCH TO PREVENT OPERATION OF THE POWER DOOR BY CHILDREN OR BY OTHERS WHO ARE NOT FAMILIAR WITH ITS USE. THE OWNER NOTIFICATION LETTER MAILING WILL BE CONDUCTED IN PHASES WITH THE FIRST PHASE BEGINNING ON MAY 31, 2005. THE SECOND PHASE MAILING BEGAN ON JULY 18, 2005. THE RECALL BEGAN ON MAY 31, 2005. PHASE 2 BEGAN ON JULY 18, 2005. PHASE 3 (FINAL PHASE) BEGAN ON AUGUST 24, 2005, TO ALL REMAINING CUSTOMERS. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438; PONTIAC AT 1-800-620-7668; OR OLDSMOBILE AT 1-800-630-6537.
Nov 4, 2002
CERTAIN PASSENGER VEHICLES AND MINI VANS HAVE LOWER PINION BEARINGS IN THE POWER RACK AND PINION ASSEMBLY IN WHICH THE RETAINER TABS WERE NOT CRIMPED PROPERLY. THESE AND SOME OTHER RETAINERS USED IN VEHICLES ASSEMBLED BETWEEN JANUARY 1, 1996 AND OCTOBER 31, 1997, COULD FAIL AND PERMIT THE BALL BEARINGS TO ESCAPE.
Consequence & remedy
Consequence: IF THIS OCCURS, THE PINION SHAFT CAN BE FORCED UPWARD DURING LEFT TURNS AND BACK DOWN AS THE STEERING WHEEL IS MOVED BACK AND TO THE RIGHT. IF THE PINION SHAFT MOVES FURTHER, THE DRIVER WILL NEED TO EXERT MORE EFFORT TO TURN THE STEERING WHEEL, SIMILAR TO A VEHICLE WITHOUT POWER ASSISTED STEERING. IF THE PINION SHAFT MOVES EVEN FURTHER, THE DRIVER WILL REQUIRE MUCH HIGHER EFFORT TO TURN LEFT AND MAY NOT BE ABLE TO TURN THE WHEEL AS MUCH AS INTENDED. WITH THE MAXIMUM PINION SHAFT MOVEMENT, WHICH REQUIRES INTERNAL GEAR COMPONENT DAMAGE, THE DRIVER CAN ENCOUNTER HIGH RESISTANCE TO TURNING LEFT, FOLLOWED BY UNINTENDED POWER ASSIST TO THE RIGHT. IN ANY OF THESE CONDITIONS, A CRASH COULD OCCUR.
Remedy: DEALERS WILL INSTALL A NEW LOWER PINION BEARING UNLESS INSPECT OF THE EXISTING BEARING INDICATES THAT REPLACEMENT OF THE GEAR ASSEMBLY IS NECESSARY. OWNER NOTIFICATION BEGAN JANUARY 24, 2003. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, PONTIAC AT 1-800-762-2737, OR OLDSMOBILE AT 1-800-442-6537.
Aug 21, 2001
VEHICLE DESCRIPTION: 1997-2001 CHEVROLET VENTURE, PONTIAC MONTANA/TRANSPORT, AND OLDSMOBILE SILHOUETTE MINI VANS EQUIPPED WITH PASSENGER SIDE POWER SLIDING DOORS THAT WERE SERVICED IN CAMPAIGN 01013 (01V-067) FROM APRIL TO AUGUST 2001. ALSO 2001 CHEVROLET VENTURE, PONTIAC MONTANA, AND OLDSMOBILE SILHOUETTE MINI VANS EQUIPPED WITH PASSENGER SIDE POWER SLIDING DOORS ASSEMBLED IN JANUARY THROUGH APRIL 2001. THESE VEHICLES HAVE INADEQUATE FRONT WELDS. IF A FRONT WELD FAILS, THE ACTUATOR CAN JAM IN THE UNLATCHED POSITION AND, WHEN THE SLIDING DOOR CLOSES, IT WILL NOT BE LATCHED.
Consequence & remedy
Consequence: IF THIS HAPPENS, THE POWER SLIDING DOOR CAN OPEN WHILE THE VEHICLE IS IN MOTION, PARTICULARLY WHEN THE VEHICLE ASCENDS A HILL, MAKES A TURN, OR TRAVELS OVER A ROUGH ROAD SURFACE. AN UNRESTRAINED OCCUPANT COULD FALL OUT OF THE VAN AND BE INJURED.
Remedy: DEALERS WILL INSPECT AND, IF REQUIRED, INSTALL A NEW POWER SLIDING DOOR UNLATCH ACTUATOR ASSEMBLY. OWNER NOTIFICATION BEGAN ON OCTOBER 22, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020, PONTIAC AT 1-800-762-2737, OR OLDSMOBILE AT 1-800-442-6537.
Mar 8, 2001
VEHICLE DESCRIPTION: MINIVANS EQUIPPED WITH PASSENGER SIDE POWER SLIDING DOORS. THE DOOR CLOSES BUT MAY NOT BE LATCHED. IF THIS HAPPENS, THE POWER SLIDING DOOR CAN OPEN WHILE THE VEHICLE IS IN MOTION, PARTICULARLY WHEN THE VEHICLE ASCENDS A HILL, MAKES A TURN, OR TRAVELS OVER A ROUGH ROAD SURFACE.
Consequence & remedy

Consequence & remedy
Consequence: BRAKE FLUID LEAKAGE CAN CAUSE REDUCED BRAKE EFFECTIVENESS AND INCREASED STOPPING DISTANCES.
Remedy: DEALERS WILL INSTALL A BRAKE LINE CLIP TO ENSURE PROPER CLEARANCE. ALSO THE BRAKE LINES WILL BE INSPECTED TO ANY DAMAGE CAUSED BY THIS CONDITION AND WILL REPLACE ANY DAMAGED LINES.
