1991 Geo Storm

Defect. THE FRONT SAFETY BELT BUCKLE RELEASE BUTTONS CAN BREAK. THESE RED PLASTIC RELEASE BUTTONS ARE MARKED "PRESS." IF A BUTTON BREAKS, PIECES CAN FALL INTO THE BUCKLE ASSEMBLY CAUSING THE BUCKLE TO OPERATE IMPROPERLY.

Risk. THE SAFETY BELTS WOULD NOT PROVIDE ADEQUATE PROTECTION TO AN OCCUPANT IN A VEHICLE CRASH.

Remedy. OWNERS SHOULD PROMPTLY CHECK THE CONDITION AND OPERATION OF BOTH FRONT SAFETY BELT BUCKLES AND CAREFULLY INSPECT THE RED RELEASE BUTTON FOR ANY BREAKS OR CRACKS. THEY SHOULD ENSURE THAT BOTH BUCKLES ARE OPERATING PROPERLY BY INSERTING EACH LATCH PLATE INTO ITS BUCKLE, TUGGING ON THE BELT TO MAKE SURE THE LATCH IS SECURELY LOCKED, AND THEN PRESSING THE RELEASE BUTTON. THE LATCH PLATE SHOULD POP OUT OF THE BUCKLE WHEN THE BUTTON IS PRESSED. IF EITHER RELEASE BUTTON SHOWS A SIGN OF BREAKING OR CRACKING OR IF EITHER BUCKLE FAILS TO OPERATE PROPERLY, OWNERS SHOULD PROMPTLY CONTACT THEIR AUTHORIZED DEALER TO SCHEDULE AN APPOINTMENT TO HAVE THE BUCKLE REPLACED OR REPAIRED, FREE OF CHARGE. THE MANUFACTURER IS DEVELOPING A REMEDY DESIGNED TO PREVENT FAILURE OF THE BUTTONS THAT ARE NOT CURRENTLY BROKEN.

Defect. THE STEERING WHEEL CENTER HUB CAN FRACTURE DURING CERTAIN FRONTAL AND NEAR FRONTAL VEHICLE COLLISIONS.

Risk. FRACTURING OF THE STEERING WHEEL HUB CAN DECREASE THEDRIVER'S CONTROL OF THE VEHICLE AND COULD REDUCE THE CRASH PROTECTION OF THESTEERING SYSTEM AND THE DRIVER'S SIDE AIR BAG.

Remedy. A STEERING WHEEL REINFORCEMENT PLATE AND NUT WILL BE ADDED TO THE STEERING WHEEL HUB.

TL* THE CONTACT OWNS A 1991 GEO STORM. THE CONTACT STATED THAT THE VEHICLE STALLED WHILE SITTING AT A TRAFFIC STOP. THE VEHICLE WAS TAKEN TO THE DEALER HOWEVER, THEY WERE UNABLE TO REPAIR THE VEHICLE. THE MANUFACTURE WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 40,000.

7 MONTHS AND 5 REPLACEMENT ECUS ON MY 1991 GEO STORM GSI, AND STILL HAS DANGEROUS ISSUES OF STALLING ON HIGHWAY AND WHEN PULLING OUT INTO TRAFFIC. THE PROBLEM IS THAT BETWEEN 1985 AND 1995, AC DELCO USED A INSULATIVE SPRAY ON THE CIRCUIT BOARDS IN THESE ECUS/COMPUTERS WHICH SHRINKS OVER TIME WHEN EXPOSED TO WARM AND COOL TEMPERATURE CONDITIONS, SUCH AS THE NORMAL CONDITIONS THAT AN AUTOMOBILE IS SUBJECTED TO. THE SHRINKING INSULATIVE SPRAY CONTRACTS AND PULLS THE ELECTRONIC COMPONENTS FROM THE CIRCUIT BOARD, BREAKING SOLDER CONNECTIONS AND CAUSING SHORTS. THE SYMPTOMS OF THIS FAULT ARE MOST NOTABLY ERRATIC IDLE, IDLE REVVING AND DROPPING, IDLE DIPPING OFTEN WITH ENGINE DYING, IDLE HANGING HIGH ABOVE 2,000 RPM, AND ENGINE DYING OR STALLING FOR NO REASON WITH NO TROUBLE CODES. GM KNOWS ABOUT THIS FAULT IN THEIR AC DELCO ECUS/COMPUTERS AND HAS EVEN GONE SO FAR AS TO INCLUDE SUPPLEMENTAL INSTRUCTIONS ON HOW TO TEST FOR SHORTS AND BROKEN CIRCUITS IN THE ECU/COMPUTER TO THEIR TECHNICAL LITERATURE, THOUGH THEY REFUSE TO REPAIR OR REPLACE THE PROBLEM AT THEIR OWN EXPENSE. GM WENT FURTHER AND BEGAN USING A DIFFERENT INSULATIVE SPRAY ON ALL OF THEIR ECUS/COMPUTERS IN 1996, THOUGH THEY DO NOT USE THIS NEW SPRAY ON THEIR FACTORY RECONDITIONED ECUS/COMPUTERS FOR THE GEO STORM MODELS. *TR

1992 GEO STORM MANUAL TRANSMISSION. WHEN ENGINE GETS HOT ( SUMMER MONTHS ) ENGINE IDLE INCREASES TO 2,500 - 3,500 RPM. MUST USE FOOT TO PULL UP ON ACCELARATOR. CAR BEGINS TO OVERHEAT LURCHES FORWARD. CAR ALSO STALLS WITHOUT WARNING. HEARD IT HAS TO DO WITH FAULTY ECM. VERY DANGEROUS SITUATION. *JB

THE E.C.U. IS BAD IN MY 1991 GEO STORM 2+2. IT IS A COMMON PROBLEM WITH THESE CARS AND GM WILL NOT DO ANYTHING ABOUT IT. *LA

THE VEHICLE STALLED WITHOUT WARNING. THE DEALER REPLACED THE DISTRIBUTOR CAP, SPARK PLUG WIRES AND ROTOR, HOWEVER THE PROBLEM RECURRED. *JB

DURING WARM WEATHER THE VEHICLE'S THROTTLE WILL STICK AT 2000. THROUGH MY RESEARCH I HAVE FOUND THIS TO BE THE FAULT OF THE ECU. IT IS A VERY DANGEROUS THING TO HAVE YOUR THROTTLE STICK. DT

ONGOING PROBLEM WITH ENGINE STALLING / CUTTING OFF WHILE DRIVING AT MULTIPLE SPEED. VEHICLE BEEN TO DEALER, BUT PROBLEM REOCCURRING. FEEL FREE TO PROVIDE ANY FURTHER INFORMATION.*AK

THIS IS THE 2ND ECM CONTROL MODULE IN 2 YEARS. . .BOTH WERE NEW WITH ONLY A YEAR WARRANTY. . .PROBLEM ONLY SHOWS UP IN THE SUMMER. *AK

GENERAL MOTORS USED A SHRINKING SEALANT ON THE COMPUTER BOARDS IN THESE CARS WHICH THEY HAVE SINCE QUITE USING AND ADMIT IT WAS A PROBLEM, BUT STILL USE IT ON THE REPLACEMENT PARTS WHEN THIS SHRINKS IT PULLS THE COMPONENTS ON BOARD LOOSE, CAUSING POOR IDLE/ HESITATION AND STALLING EVEN DURING ACCELERATION (IE WHEN PULLING OUT IN TRAFFIC). *AK

NO SUMMARY LISTED FOR ABOVE VEHICLE. *AK

ENGINE CONTROL COMPUTER IMPROPERLY BUILT CAUSING ERRACTIC IDLE FROM 2000RPM TO 500RPM, CAR STALLS AND WILL NOT START. ISUZU HAS BEEN CONTACTED ABOUT THIS AND HAS STATED"WE DO NOT MAKE CARS" AND THEY FAIL TO RECTIFY THE PROBLEM. THERE ARE VERY MANY OF US WHO WOULD LIKE TO SEE THIS ISSUE RESOLVED AS OUR CARS STALLING IN TRAFFIC AND IDLING ERRACTICALLY IS CAUSING A LOT OF PROBLEMS AS IN POOR EFFICIENCY AND UNNEEDED DOWNTIME. THE PROBLEM IS IN THE INSULATIVE SPRAY ON THE MAIN CIRCUIT BOPAR DOF THE UNITS THAT BREAKS DOWN OVER TIME DUE TO HEAT AND EXTREME(HOT OR COLD) TEMPS. GMC HAS RECOGNIZED THIS PROBLEM AND FAILS TO DO ANYTHING ABOUT IT. WE WOULD LIKE THIS ISSUE ADDRESSED AND I SPEAK FOR THE OVER 500 MEMBERS OF THE GEO STORM OWNERS CLUB, WWW.STORMOWNERS.COM. *AK

IDLE BECOMES ROUGH, BOUNCES AND DIES, FAILS TO START OR STARTS AND CHECK ENGINE LIGHT IS ON, RUNS VERY BAD. ONCE CAR SITS FOR A WHILE, STARTS TO RUN FINE, DOES IT WHEN IT IS WARM OUT. *AK

I WAS COMING DOWN A 2 LANE AND IT JUST STOPPED AND GOT REAR ENDED WHEN IT SHUT OFF IT WAS THE ECM SHORTED BECAUSE OF SEALANT FROM FACTORY. *AK

FOR THE LAST 4YRS. I HAVE HAD TROUBLE AT START-UP,IDLE,DRIVABILITY OF THE ENGINE. ALL SENSORS RELATED TO THE IGNITION HAD BEEN CHECKED OR REPLACED. NOW ON 12/1/01 THE ALTERNATOR OVER CHARGED THE ELECTRICAL SYSTEM CAUSING A COMPLETE BURN-UP OF THE ECM,MAIN CIRCUIT PANEL AND SOME OF THE WIRING HARNESS. NEITHER THE 50AMP MAIN FUSE OR THE 30AMP ECM FUSE BLEW (LIKE THEY SHOULD HAVE) STOPPING THE 160 AMPS FROM THE ALTERNATOR. *AK

THE DATE & MILEAGE ARE ONLY FOR THE MOST RECENT OCCURENCE. IT STARTED LATE APRIL 2001 AT ABOUT 70,000 MILES; I'D BOUGHT THE CAR USED THE PREVIOUS SEPTEMBER & IT HAD DRIVEN OK THROUGHOUT THE WINTER. THE PROBLEM HAS BEEN HAPPENING OFF & ON EVER SINCE. THE CAR WILL BE GOING 55 MPH OR MORE; ABOUT 5 OR MORE MINUTES AFTER STARTUP (IT VARIES), THE RPM GAUGE/IDLE SUDDENLY DROPS TO 0, THE CAR MIGHT BUCK SLIGHTLY,THE ENGINE LIGHT COMES ON, & THE CAR STALLS. PRESSING THE GAS PEDAL HAS NO EFFECT; ALL I CAN DO IS COAST TO A STOP. SO FAR, I'VE BEEN LUCKY; I'VE BEEN ABLE TO COAST TO THE SHOULDER W/NO INCIDENT. USUALLY AFTER A COUPLE MINUTES, I CAN START THE CAR AGAIN,BUT THIS PAST SATURDAY, I WAS STRANDED FOR OVER AN HOUR BEFORE THE CAR WOULD START. THE PROBLEM HAPPENS IRREGULARLY, USUALLY WHEN IT'S WARM OUTSIDE. THE IDLE ALSO REVS ON ITS OWN; WHENEVER I TAKE MY FOOT OFF THE GAS & THE SPEED DROPS BELOW 30 MPH, IT REVS & JUMPS FORWARD UNLESS I IMMEDIATELY HIT THE BRAKES -- VERY DANGEROUS WHEN I'M HEADING TOWARDS A STOPLIGHT! THE CAR HAS HAD BOTH ITS IGNITION COIL & FUEL INJECTORS REPLACED, AND ALL BELTS ARE NEW; ALL MAINTENANCE IS KEPT UP, & THERE ARE NO OTHER PROBLEMS WITH THE CAR THAT WOULD CAUSE EITHER OF THESE ISSUES. AFTER DRIVING OUR MECHANIC & US NUTS FOR SEVERAL MONTHS, WE FINALLY FOUND OUT THAT THE PROBLEMS WERE DUE TO SHORTS CAUSED BY BAD INSULATIVE SPRAY ON THE ECU/COMPUTER CIRCUIT BOARD (THE ORIGINAL FACTORY INSTALLED UNIT), & WE ALSO FOUND OUT THAT WE WEREN'T ALONE IN HAVING THE

I SENT ONE COMPLAINT TODAY, WITH SOME ERRORS. I AM SENDING THIS COMPLAINT TO CORRECT THESE ERRORS, AND ALSO TO COMPLAIN A LITTLE MORE. I CAN BARELEY MAKE IT TO SCHOOL IN MY CAR WITHOUT WORRING IF IT IS GOING TO DIE OR NOT. SEVERAL TIMES IT HAS DIED IN THE MIDDLE OF BUSY INTERSECTIONS NOT ONLY PUTTING MYSELF IN DANGER, BUT ALSO THE OTHER MOTRISTS AROUND ME. I AM A YOUNG KID ON A TIGHT BUDGET AND WOULD LIKE TO SEE SOMETHING DONE ABOUT THIS. THANK YOU. *AK
