1991 CHEVROLET LUMINA Engine And Engine Cooling Problems

LTR FM NORMAN PARKER (MI). LOSS OF STEERING CONTROL DURING OPERATION DUE TO ENGINE CRADLE BOLT FAILURE. *PH

CONSUMER STATES ATTEMPTED TO ACCELERATE FROM A STOP LIGHT AND STEERING WHEEL TURNED COMPLETELY AROUND IN A CIRCLE AND CONSUMER LOST CONTROL. DLR DETERMINED THAT THE ENGINE CRADEL BOLTS BROKE. CURRENT RECALL 00V189000 DOES NOT INCLUDE CONSUMER'S VEHICLE. TS

THE RADIATOR FAILED AT SEAM IN THE PLASTIC AT THE TOP WHERE THE UPPER HOSE ATTACHES, AFTER FAILING I CONSULTED OTHER LUMINA OWNERS WHO ENCOUNTERED THE SAME EXACT LEAK IN THE SAME PLACE, I WENT TO THE JUNK YARD TO FIND EVERY LUMINA HAD THE SAME LEAK, I THINK THIS IS MANUFACTURE FLAW. THE OIL LEAK THAT HAPPENED WHEN THE OIL PUMP DRIVESHAFT GAVE WAS VERY BAD. I CONSULTED OTHERS THEN AND FOUND IT IS A VERY COMMON PROBLEM THAT IS KNOW BY ALL MECHANICS KNOW ABOUT. IT IS NOT IF IT WILL GIVE, IT'S WHEN.*AK

CONSUMER STATED THE VEHICLE WOULD OVERHEAT AND HAS ALSO STALLED ON SEVERAL OCCASIONS.*JB

THE VEHICLE WOULD NOT STEER PROPERLY DUE TO BROKEN ENGINE CRADLE BOLTS. THE DEALER REPAIRED IT AND REPLACED THE BROKEN SWITCH, RECONNECTING THE STEERING RACK ALSO. *YH

WHEN TURNING AT 10MPH ENGINE MOUNT BROKE, ENGINE DROPPED, SNAPPED STEERING COLUMN, WHICH CAUSED STEERING WHEEL TO COMPLETELY AROUND, DRIVER LOST CONTROL OF VEHICLE.*AK

WHILE DRIVING THERE WAS A LOUD NOISE. ONE OF THE RADIATOR FANS HAD FALLEN OFF AND BOLT CAME OFF THE OTHER.*AK

CONSUMER WAS TRAVELING ABOUT 35MPH ON A SIDE STREET, APPLIED BRAKES AND LOST CONTROL OF VEHICLE, HE ENDED UP INSIDE OF A PARKING LOT, SUBFRAME FELL IN THE STREET.*AK. CONSUMER DISCOVERED THAT THERE WAS A RECALL FOR THE EXACT SAME MODEL OF VEHICLE FOR THE SAME PROBLEM, BUT HIS VEHICLE WAS NOT INCLUDED, ALSO THE REAR BRAKES WERE INOPERATIVE, A STARTER, 2 ALTERNATORS, 2 WATER PUMPS, A BAD CRANKCASE OIL LEAK, 2 SERPENTINE BELTS, THE LEFT FRONT WINDOW WAS INOPERATIVE, A NEW THERMOSTAT, A FUEL PUMP, FUEL INJECTOR, TIE ROD END, THE REAR STRUT FELL APART, THE STEERING JOINT BECAME COMPLETELY DISENGAGED FROM THE SUBGRAME, THE LIGHT SWITCH ON THE STEERING COLUMN WAS INOPERATIVE.*JB

BOTH BOLTS PULLED THROUGH AND IT WAS NO LONGER MOUNTED TO THE LOCATIONS AND BROKE THE STEERING SHAFT.*AK

CAR HAS BEEN IN AND OUT OF CHEVROLET DEALERSHIP FOR 2 YRS TRYING TO DETERMINE STALLING PROBLEM. ECM AND PROM FAILED, CAUSING CATALYTIC CONVERTER TO ALSO NEED REPLACEMENT. BRAKES HAVE BEEN SERVED EVERY 3000 MILES BECAUSE THEY DO NOT ALLOW CAR TO STOP AT NORMAL STOPPING DISTANCE. BRAKES SEEM TOO SOFT, HAS NEARLY CAUSED A FEW ACCIDENTS BECAUSE BRAKES DO NOT STOP THE CAR, NEARLY SLOW IT DOWN. BRAKES HAVE BEEN SERVICED BY CHEVROLET TECHNICIAN. WHY HAVEN'T THESE PARTS BEEN RECALLED IF SO MANY PEOPLE ARE EXPERIENCING PROBLEMS WITH THE SAME DEFECTS?

RATTLING NOISE EVERY TIME I PARK OR SIT. SOUNDS NEAR THE MOTOR. CARBURATOR IS CLOGGED. LEFT PASSANGER DOOR DOES NOT OPEN. HESITATION OF MOTOR WHILE ACCELERATION, BRAKES AND ROTORS ARE BAD ON THE BACK LEFT AND RIGHT TIRES.

WHILE DRIVING VEHICLE WILL COMPLETELY SHUTDOWN WITHOUT WARNING, CAUSE UNKNOWN. *AK THEE VEHICLE STALL AT THREE DIFFERENT OCCASIONS AND FIXED BY THE DEALER. FIRST TIME THEY SAID IT COULD BE PLUGS, THEY REPLACED, SECOND THEY REPLACED EGR VALVE BUT THE PROBLEM CONTINUED AND AT LAST INJECTORS WAS GUESED TO BE THE CAUSE AND WAS FIXED STILL NO REMEDY IS FOUND FOR STALLING. *YH

WHILE PULLING OFF THE HIGHWAY AT APPROXIMATELY 30 MPH VEHICLE LOST COMPLETE STEERING CONTROL. VEHICLE TOWED TO INDEPENDENT REPAIR SHOP FOR REPAIRS. *AK THE REPAIR SHOP DETERMINED THAT THE ENGINE DROPPED CAUSEING THE STEERING COLUMN TO SEPARATE. *YH

THE THROTTLE STICKING IS VERY HAZARDOUS AND UNSAFE. ALSO THE CONTINUING OF OVERHEATING DUE TO A MANUFACTURED ITEM IS OF GREAT CONCERN TO ME. I HAVE 2 SMALL CHILDREN AND DO NOT WANT TO BE LEFT BY ROADSIDE SOMEWHERE AT NIGHT DUE TO THIS MALFUNCTION. *AK

1991 CHEVROLET LUMINA Z34 W/3.4L ENGINE. WAS A KNOWN PROBLEM BY SHOP FOREMAN @ SMEDLEY'S CHEVROLET OF VANDALIA, OHIO....JOE. NO SAFETY DEFECT LISTED IN THE SUMMARY. *AK

WHILE DRIVING AT 35 TO 45 MPH VEHICLE WILL SHUT DOWN, CAUSING A LOSS OF POWER WITHOUT WARNING. SOMETIMES IT WILL START RIGHT BACK UP, AND SOMETIMES IT TAKES 15 TO 20 MINUTES. DEALER HAS BEEN CONTACTED, AND REPLACED TTC SOLENOID ONCE, BUT THAT DID NOT SOLVE THE PROBLEM. DEALER SAID THAT OWNER WILL HAVE TO WAIT UNTIL VEHICLE BREAKS DOWN COMPLETELY TO FIND THE PROBLEM. *AK *ML

EXHAUST VALVES ARE STICKING, CAUSING THE TIMING BELT TO SLIP. WE HAVE REPLACED THE BELT AND THE PROBLEM IMMEDIATELY RECURRED. GM HAS BEEN AWARE OF THE PROBLEM FOR YEARS, BUT HAS BEEN FAIRLY QUIET ABOUT RESOLVING IT. THEY PRODUCED A NUMBER OF 3.4 ENGINES WITHOUT CHROME PLATED EXHAUST VALVES, AND THE SOFTER VALVES DISTORTING AND STICK, CAUSING THE ENGINE TO JUMP TIMING. THIS IS A SOPHISTICATED DUAL OVERHEAD CAM V-6 AND TOLERANCES ARE CRITICAL. GM ISSUED A DIRECTIVE TO REPLACE THE CYLINDER HEADS ON THE AFFECTED ENGINES, HOWEVER OURS WAS NOT INCLUDED IN THE RECALL, EVEN THOUGH IT WAS BUILT IN THE PLANT THAT PRODUCED THE ENGINES AND IS IN LINE WITH THE SEQUENCE OF ID NUMBERS. GENERAL MOTORS IS DISAVOWING THE PROBLEM, EVEN THOUGH IT IS A KNOWN DEFECT. THEY HAVE REPLACED A NUMBER OF CYLINDER HEADS AND EXHAUST VALVES, AND I BELIEVE THEY SHOULD ACKNOWLEGE THEIR ERROR IN OUR CAR AND REPAIR OUR ENGINE. BECAUSE OF THE SOFT EXHAUST VALVES, THERE IS NO ALTERNATIVE BUT TO MAKE MAJOR REPAIRS, ALL DUE TO IMPROPER MANUFACTURING. *AK

WHILE TRAVELING 55 MPH VEHICLE STALLS WITHOUT INDICATION. DEALER HAS BEEN NOTIFIED, CAN' T DUPLICATE PROBLEM. ALSO,ALTERNATOR/BATTERY/COMPUTER, AND FUEL FILTER LINE FAILED AND WERE REPLACED BY DEALER. *AK

FRONT ENGINE MOUNTS BROKE WHILE GOING 55MPH. LOST CONTROL ON A 6-LANE HIGHWAY DURING RUSH HOUR TRAFFIC. ALSO, FRONT LEFT TIRES HAD BLOWN OUT. HAD NO WARNING IN THAT REGARD. MANAGED TO GET VEHICLE TO SIDE OF ROAD. VEHICLE WILL BE TOWED TO DEALER. *AK
