2002 Chevrolet Tahoe Engine Problems

Your vehicle needs new exhaust manifold bolts, which have been identified as a recurring issue on this model. Loose or failing bolts can allow exhaust fumes to leak into the cabin, potentially exposing you and your passengers to harmful gases. The manufacturer hasn't issued a recall for this problem. Getting the bolts replaced should seal the exhaust system properly.

TL* THE CONTACT OWNS A 2002 CHEVROLET TAHOE. THE CONTACT STATED THAT THE LOW COOLANT WARNING LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE CYLINDER HEADS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 130,000.

TL* THE CONTACT OWNS A 2002 CHEVROLET TAHOE. THE CONTACT STATED THAT AFTER STARTING THE VEHICLE, HE NOTICED AN ABNORMAL TICKING. THE CONTACT INSPECTED THE VEHICLE AND NOTICED A BROKEN HEAD ON THE EXHAUST MANIFOLD BOLTS. THE CONTACT STATED THE EXHAUST FUMES WERE NOT ESCAPING FROM THE EXHAUST PIPE BUT REMAINING IN THE ENGINE COMPARTMENT. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 98,000.

THE EXHAUST BOLTS ARE BREAKING CAUSING THE EXHAUST TO LEAK. THE RELATED PROBLEMS WILL LIKELY BE POOR FUEL ECONOMY, INCREASED EMISSIONS AND POTENTIALLY FAILED EMISSIONS TEST. THE CATALYTIC CONVERTER WAS ALREADY REPLACED ON THE SAME SIDE AS THE EXHAUST MANIFOLD WITH THE BROKEN BOLTS. PROBLEM WAS NOT NOTICED UNTIL THE SECOND BOLT BROKE THUS NOT SURE WHEN THE ORIGINAL PROBLEM OCCURRED. THE PROBLEM APPEARS TO EFFECTING NUMEROUS OTHER VEHICLES THUS A POTENTIAL LARGE GLOBAL IMPACT. *TR

2002 CHEVY TAHOE WITH 105, 000 MILES. CHANGED SPARK PLUGS AND FOUND A SEVERED EXHAUST MANIFOLD BOLT ON THE ENGINE. THE BOLT IS FROM THE DRIVER'S SIDE END OF MANIFOLD. THE BOLT IS WORN AND RUSTY ON 90% OF IT AND THE OTHER 10% IS SHINY (LIKE A NEW BREAK). CALLED DUBLIN, CA CHEVY AND WENT IN AFTER THEY SAID THEY HAVE HAD MANY COMPLAINTS. THE OFFERED TO FIX IT FOR 10% OFF THE $1000 BILL. I TOLD THEM THAT IT WAS THEIR DEFECT AND THEY SHOULD PAY. I CALLED GMAC AND THEY TOLD ME TO GOTO ANOTHER CHEVY DEALER IN SAN LEANDRO, CA FOR A DIAGNOSIS SINCE THE 1ST DEALERSHIP NEVER LOOKED UNDER THE HOOD. THAT DEALER LOOKED AT THE TRUCK AND TOLD ME THAT THEY WOULD HAVE TO REMOVE THE MANIFOLD AND IT WOULD COST APPROXIMATELY, $500, BUT IT COULD RUN MORE IF THERE WERE MORE BOLTS THAT BREAK OFF DURING THE REPAIR. I HAVE THREE YOUNG CHILDREN AND I HAVE TAKEN IMMACULATE CARE OF THIS TRUCK. I DON'T THINK I SHOULD HAVE TO PAY FOR A REPAIR WHEN IT IS OBVIOUS BY LOOKING AT THE BOLT THAT THE BOLT WAS OVER TORQUED WHEN THE VEHICLE WAS BUILT. AFTER MUCH RESEARCH, I HAVE FOUND THOUSANDS OF COMPLAINTS OF THIS EXACT PROBLEM. THEY NEED TO RECALL THESE VEHICLES AND FIX THEM. IF I LET THIS CONTINUE WITHOUT FIXING THE PROBLEM, I WILL HAVE A HUGE PROBLEM ON MY HANDS AND IT WILL BE A SAFETY ISSUE. *TR

2002 CHEVROLET TAHOE. ONE OWNER VEHICLE, BOUGHT NEW. FLUTTER/RATTLING SOUND WHEN ACCELERATING WITH AIR CONDITIONER ON. DOES NOT RATTLE WHEN COMPRESSOR IS OFF. REAR AIR STOPPED BLOWING COLD. MECHANIC STATES SEVERAL PEOPLE WITH THE SAME PROBLEM. REPLACED TENSIONER PULLEY. BELTS. STILL RATTLING/ LOUD. NOW STATES COMPRESSOR/CONDENSER NEED REPLACING BEFORE SEIZES UP. MECHANIC STATES THIS IS A KNOW DEFECT OF THIS MODEL, BUT NOT AWARE OF RECALLS. THIS NEEDS TO BE ADDRESSED SINCE IT SEEMS TO BE A MECHANICAL DEFECT. *TR

ABOUT 2 YEARS AGO I NOTICED ENGINE COOLANT ON MY GARAGE FLOOR. AFTER INVESTIGATING I FOUND THAT THE LEAK WAS COMING FROM THE STORAGE RESERVOIR RATHER THAN THE RADIATOR. I ALSO NOTICED THAT MY WINDSHIELD WASHER FLUID WAS ALSO LEAKING ONTO THE GARAGE FLOOR. I TOOK MY TAHOE INTO A DEALER. I EXPLAINED THE PROBLEMS, THEY CONDUCTED THEIR EVALUATIONS AND I WAS THEN TOLD THAT IT WOULD COST APPROXIMATELY $450.00 TO REPAIR BOTH PROBLEMS. I COULD ONLY AFFORD TO FIX ONE PROBLEM SO I CHOSE THE COOLANT LEAK. THEY "FIXED" THE LEAK...FOR ABOUT $250.00. THE COOLANT RESERVOIR LEAK REAPPEARED SEVERAL MONTHS LATER. THE TAHOE WAS THEN OUT OF WARRANTY AND APPARENTLY TO FIX THESE ISSUES IT TAKES LOTS OF TIME AND EXPERTISE. THESE PROBLEMS ARE BECOMING EXPENSIVE AND CONTINUE TO BE ANNOYING. I AM BEING TOLD NOW THAT THE PROBLEMS ARISE FROM THE FLUID CONTAINERS RUBBING AGAINST THEIR MOUNTING BOXES WHICH IS CREATING HOLES IN THE CONTAINERS. ANY SUGGESTIONS? STEVE MULLIS *TR

I JUST BOUGHT A TRUCK FROM A USED CAR DEALER, WHO SAID NOTHING WAS WRONG WITH THE VEHICLE. THERE IS A PROBLEM WITH THE HEATING AND COOLING. WHEN I TURN OFF THE A/C IT STILL BLOWS AIR OUT OF THE VENTS, AND THE TRUCK NEEDS U JOINTS. *TR

2002 TAHOE SHUTS DOWN AT HIGHWAY SPEEDS. SIT FOR FIFTEEN MINUTES STARTS BACK UP. ONLY HAPPENS IN 90+ DEGREE DAYS. SOMEONE IS GOING TO GET HURT. I'VE SEEN NUMEROUS COMPLAINTS IN THE COMPLAINT DBASE. *TR

THE FLUTTERING/GRINDING NOISE ACTUALLY BEGAN AROUND AUGUST '06. I HAD TO DRIVE WITHOUT AC WITH WINDOWS DOWN TO SURVIVE THE HEAT. I ASKED A LOCAL AUTO REPAIR STATION ABOUT THE NOISE, SINCE IT WAS OUT OF WARRANTY, AND HE SAID HE HAD WORKED ON SEVERAL TAHOES WITH THE SAME PROBLEM. HE SAID THAT THE CHEVROLET DEALERSHIP KNEW ABOUT THE PROBLEM BECAUSE THEY INSTANTLY TOLD HIM WHAT HAD TO BE REPLACED. THEY TOLD HIM THE AVERAGE REPAIR BILL FOR THIS ISSUE WOULD BE APPROX $1500 AT THE DEALERSHIP. SINCE THEN I HAVE HEARD OTHER TAHOES WITH THE SAME NOISE , ESPECIALLY AT STOPLIGHTS WHEN THEY ACCELERATE. NOT EVERYONE CAN AFFORD THAT KIND OF REPAIR, AND IF CHEVORLET KNOWS ABOUT THIS ISSUE, WHY HASN'T THERE BEEN A RECALL. THIS IS NOT THE TYPICAL AND ROUTINE WEAR LIKE OIL CHANGES AND TIRES. *TR

LOW COOLANT LIGHT ON MY 2002 CHEVY MALIBU HAS BEEN COMING ON. THE CHEVY DEALER CHECKED THE LOW COOLANT LIGHT COMING ON, CHECKED FOR LOW COOLANT. FOUND INTAKE MANIFOLD GASKET LEAKING INTERNALLY. COOLANT MIXING WITH OIL. *NM

DT: THE CONTACT STATED TRUCK STALLED AT 60 MPH. NO LIGHTS CAME ON, IT JUST CUT OUT. IT USUALLY RESTARTED AFTER THE SECOND TIME. WHEN PARKING THE TRUCK AND LETTING IT SIT OVERNIGHT WITH OF TANK OF GAS IT WILL NOT START THE NEXT DAY UNTIL THE CONTACT PUT MORE GAS INTO THE TANK. AS LONG AS VEHICLE DID NOT SIT OVERNIGHT IT WILL USUALLY RESTART. THE CONTACT NOTICED THIS HAPPENING AT 90,000 MILES. HE KNEW SOMEONE ELSE WHO HAD THE EXACT SAME PROBLEM.*AK

FLUTTER/RATTLING COMPRESSOR LIKE SOUND WHEN ACCELERATING. APPEARS TO BE FROM A/C COMPRESSOR. FROM MY RESEARCH, OTHER OWNERS HAVE REPORTED SIMILAR COMPLAINTS. DEALER SAY THIS IS NOT A EQUIPMENT FAILURE ISSUE.*AK

I HAVE A 2002 CHEVROLET TAHOE. ONCE THE VEHICLE SETS OVERNIGHT OR A PERIOD OF SIX HOURS OR LONGER THE FOLLOWING PROBLEM OCCURS: I GO TO BACK OUT OF MY DRIVEWAY IN REVERSE THE VEHICLE ENGINE WILL DIE. NOTE THAT MY DRIVE WAY IS ON AN INCLINE. THIS CANNOT BE RECREATED IF THE DEALERSHIP ATTACHES A TECH TOOL TO THE VEHICLE. THIS PROBLEM CAN BE RECREATED WITHOUT FAIL WITH NOTHING ATTACHED. I HAVE ALSO HAD ONE OCCURRENCE THAT AFTER I STARTED THE VEHICLE BACK, WHICH IT WILL ALWAYS START BACK, I WAS ATTEMPTING TO PULL OUT ON A MAJOR ROAD WHEN THE VEHICLE APPEARED TO TRY AND STALL OUT. LUCKILY THE VEHICLE PICKED BACK UP AND RESPONDED NORMALLY JUST A SECOND BEFORE I WAS NEARLY STRUCK BROADSIDE BY A SEMI-TRUCK. THE DATE BELOW IS APPROXIMATELY WHEN THE PROBLEM STARTED. *JB

THE FAN BELT MADE A NOISE. *JB

PERIODICALLY, WHEN THE CAR IS STARTED FROM A STOPPED POSITION, THE ENGINE WILL REV AND THE CAR DOES NOT GO. SEEMS LIKE SOMETHING IN TRANSMISSION IS SLIPPING. HAVE TAKEN TO THE DEALER AND THEY CANNOT LOCATE A PROBLEM.
