2001 Chevrolet Tahoe Engine Problems

MISFIRING, EXHAUST LEAKING BECAUSE OF COMMON PROBLEM (EXHAUST MANIFOLD BOLTS BROKEN) MANY HAVE COMPLAINED OF THE SAME PROBLEM ON THE V8 ENGINES. THERE NEEDS TO BE A RECALL. HELP! *TR

TWO EXHAUST MANIFOLD BOLTS ARE BROKEN. THE SERVICE ENGINE SOON WARNING ON. THERE SHOULD BE A RECALL BY GM TO FIX THIS UNDER WARRANTY. DUE TO THE RESEARCH I'VE DONE, THIS PREMATURE BOLT BREAKAGE PROBLEM IS COSTING CONSUMERS MILLIONS IN REPAIR COSTS THAT SHOULD NOT BE OUR RESPONSIBILITY. *TR

EVERY MORNING WHEN THE VEHICLE IS STARTED THERE IS A "CLICKING" NOISE. IT INCREASES IN SPEED WITH RPM. ONCE HITS 2000 (OR SO) RPM, NOISE WILL STOP. NOISE WILL ALSO QUIT AFTER 5 MINS OF IDLE. CANNOT DETERMINE CAUSE. HAPPENS REGARDLESS OF OUTSIDE TEMP, HOWEVER IS BETTER IN AZ SUMMER MONTHS. MECHANIC CANNOT FIND SOURCE OF THE PROBLEM. ALL IDEAS/SOLUTIONS WELCOME. *TR

I HAVE A 2001 TAHOE WITH A 350 MOTOR IN IT WITH 136,000. IT BEGAN TO MAKE A NOISE SO I TOOK IT TO A MECHANIC. FIRST WE THOUGHT IT WAS A PULLEY, BUT AFTER TAKING THE VALVE COVERS OFF IT WAS NOTED THAT THE NOISE WAS LOUDER AND THE OIL SUPPLY TO THE HEADS WAS NOT WHAT IT SHOULD BE. NOW I AM TOLD THAT IT WOULD BE MORE COST EFFECTIVE TO PUT A USED MOTOR IN IT FOR $3,000 (71,000 MILES). THEY CAN NOT TELL ME WHY THIS HAPPENED AND I DID MY PART BY MAINTAINING MY VEHICLE ON TIME EVERY TIME IT NEEDED SCHEDULED MAINTENANCE. I AM SICK ABOUT THIS. *TR

PURCHASED BRAND NEW 2001 CHEVY TAHOE AND WITHIN FIRST 3 MONTHS NOTICED OIL LEVEL WAS LOWER THAN EXPECTED. BEGAN 'OIL CONSUMPTION' TEST WITH TRACY DEALERSHIP THAT EXTENDED INTO 2004 UNTIL THEY FINALLY AGREED 2 TEAR DOWN THE ENGINE...ALL 3 YEARS WAS ONGOING OIL LOSS WITHIN THE ENGINE! THEY ONLY WENT 2 THE CYLINDER HEADS DESPITE SEVERAL REQUESTS BY EXPERT MECHANIC'S ADVICE 2 GO FURTHER INTO THE PISTON LEVEL. TRACY CHEVROLET REPORTED THEIR FINDINGS AS 'PARTS MISSING FROM CYLINDER HEADS FROM ORIGINAL ENGINE ASSEMBLY'. GM'S CEO PROMISED 2 REPLACE MY ENGINE IF THE OIL CONSUMPTION WASN'T FIXED. WITHIN 1 MONTH OF THAT REPAIR, OIL LOSS CONTINUED. ANOTHER 'OIL CONSUMPTION' TEST SCENARIO WAS ESTABLISHED AND ANOTHER 3 YEARS PASSED WITH ME REPORTING 2 THEM EVERY 500 MILES FOR OIL LEVEL CHECKS. AGAIN, 3 YEARS PASSED BEFORE THEY FINALLY DECIDED 2 TEAR THE ENGINE DOWN AGAIN. (3/7/07). THE CYLINDER HEADS WERE FINE SO GM RECOMMENDED THAT THEY GO DOWN 2 THE PISTON LEVEL (SOUND FAMILIAR??) WHERE THEY FOUND ANOTHER MISSING PART FROM ORIGINAL FACTORY ASSEMBLY! (OIL CONTROL RINGS) THEY TRIED 2 HAVE ME ACCEPT THEY WERE DOING ME A FAVOR AS I WAS NOW OUT OF WARRANTY. I HAD 2 REMIND THEM THAT I REPORTED THIS 2 THEM WELL WITHIN MY 1ST YEAR, THEY WERE RESPONSIBLE FOR DELAYING APPROPRIATE REPAIRS, AND NOW, THIS ENGINE WAS PROBABLY MISSING OTHER PARTS. I WAS HOLDING THEM 2 THEIR ORIGINAL PROMISE OF REPLACING MY ENGINE. THE CEO'S OFFICE HAS IT WELL DOCUMENTED YET THEY ARE GOING BACK ON THEIR PROMISE AND WANT ME 2 JUST KEEP AN UNSAFE, UNRELIABLE ENGINE. THEY CAN'T GUARANTEE THAT OTHER VITAL PARTS AREN'T MISSING AND I DOUBT ANY OF THEM WOULD FEEL SAFE WITH THIS ENGINE. CAN YOU TELL ME WHAT DAMAGE HAS OCCURRED 2 OTHER ENGINE PARTS DUE 2 THIS EXTENSIVE PROLONGED OIL LOSS? THEY REFUSE 2 PROVIDE ANY FURTHER ASSISTANCE, INFORMATION, OR MY REPLACEMENT ENGINE. THEY ARE OFFERING ME INSTEAD 3 FREE OIL CHANGES FOR 6 YEARS OF WORRY, INCONVENIENCE, AND ENDURING THEIR COMPLACENCY WITH THIS SAFETY ISSUE. *JB

TL*THE CONTACT OWNS A 2001 CHEVROLET TAHOE. THE CONTACT NOTICED THAT THE VEHICLE WAS EXPERIENCING OIL CONSUMPTION FAILURE. TRACY CHEVROLET PERFORMED AN OIL CONSUMPTION DIAGNOSTIC THAT SPANNED THREE YEARS. THE RESULT OF THE DIAGNOSTIC WAS THAT THERE WAS POTENTIAL ENGINE FAILURE. IN 2004, THE DEALER STATED THAT THE CYLINDER HEAD LEVEL WAS MISSING A PART FROM THE FACTORY ASSEMBLY. TWO MONTHS LATER, THE VEHICLE CONTINUED TO EXPERIENCE OIL CONSUMPTION FAILURE. A GENERAL MOTORS CUSTOMER SERVICE AGENT PROMISED TO PROVIDE A NEW ENGINE IF THE REPAIR TO THE CYLINDER DID NOT REMEDY THE FAILURE. THREE YEARS LATER, THE DEALER PERFORMED ANOTHER OIL CONSUMPTION TEST AND FOUND YET ANOTHER PART MISSING FROM THE ORIGINAL ASSEMBLY. THE CONTACT ASKED GENERAL MOTORS TO REPLACE THE ENGINE AS PROMISED BUT THEY REFUSED TO COMPLY. THE CURRENT MILEAGE IS 83,600 AND FAILURE MILEAGE WAS 15,000.

VEHICLE STALLING IN TRAFFIC AND IN REVERESE

WHILE DRIVING AT ANY SPEED CONSUMER HEARD A LOUD NOISE COMING FROM THE FRONT. VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION, AND MECHANIC DETERMINED THAT THE LOUD NOISE WAS NORMAL. *AK *NM

VEHICLE FAILED TO START AND THE SECURITY LIGHT CAME ON THE DASHBOARD. *AK

A LOUD EMBARRASSING AND ANNOYING INTERNAL ENGINE KNOCK. DEFECTIVE DUE TO DESIGN AND MANUFACTURING QUALITY CONSISTENCY PROBLEMS. HIGHER THAN NORMAL LEVELS OF WEAR RELATED MATERIALS IN OIL ANALYSIS. VERTICAL PISTON AND CYLINDER WALL SCUFFING/SCRATCHING OR SCORING ON THE HAMMERING (NOISY) CYLINDERS UPON VISUAL INSPECTION. REDUCED COMBUSTION CHAMBER COMPRESSION ON THE HAMMERING (NOISY) CYLINDERS. INCREASED OIL CONSUMPTION. INCREASED EXHAUST EMISSIONS. *JB

OIL LIGHT FLASHED ON THE DASHBOARD. THIS CAUSED THE VEHICLE TO SHUT DOWN. CONSUMER TOOK THE VEHICLE TO THE DEALER FOR ANALYSIS, AND MECHANIC NOTICED SLUDGE INSIDE OF THE ENGINE. *AK

NHTSA#00-V-343-000: CONSUMER HAS THE SAME PROBLEM AND DEALER COULD NOT DUPLICATE OR CORRECT THE PROBLEM. PH

WHILE TRAVELING ON THE HIGHWAY WITHOUT PRIOR WARNING THE VEHICLE WILL SHUT DOWN. PLEASE PROVIDE ADDITIONAL INFORMATION, DEALER IS AWARE OF THE PROBLEM. PH

THERE IS A LOUD SQUEAKING NOISE WHEN DRIVING. CONSUMER STATES' TOOK VEHICLE TO DEALAER. TS

THE ROOF STRUT THAT THE HEADLINER ATTACHES TO IS PUNCHED TOO BIG FOR THE PLUGS THEY INSTALLED. GM HAS REPLACED THE HEADLINER, PLUGS, AND NOW WANT TO INSTALL FELT AROUND THE PLUD AND "RAM IT BACK IN" WHICH IS NOT A FIX FOR THE PROBLEM. I HAVE BEEN VERY PATIENT WAITING FOR THEM TO EITHER REPLACE THE STRUT OR THE CAR. I AM AT THE END OF MY ROPE WITH THIS, CAN YOU PLEASE ADVISE ME WHAT TO DO? DT

THE CONSUMER STATED THAT THE ENGINE CLICKS WHEN IT IS COLD. *YH

I FEEL THAT I STOPPED THE VEHICLE JUST SECONDS BEFORE IT WOULD HAVE BURST INTO FLAMES, BECAUSE WHEN I OPENED THE HOOD TO SEE WHERE THE SMOKE AND SMELL OF BURNING METAL AND PLASTIC WAS COMING FROM THE CATALYTIC CONVERTER WAS COMPLETLY RED AND GLOWING FROM THE ENGINE MALFUNCTION.
