2001 CHEVY SUBURBAN 8.1 WHEN DRIVING AT ALL SPEEDS JUST DIES. STARTS BACK UP 5-15MINS. REALLY SCARY IF YOUR DOING 75 MPH IN HEAVY TRAFFIC. I AM 99% SURE ITS THE CRANKSHAFT SENSOR. GM HAS A RECALL ON 2001 2500 HD TRUCKS ONLY!!!!I FOUND OUT ABOUT THE CRANKSENSOR FROM SOME PEOPLE ONLINE WHO LEARNED THE HARD WAY .WITH TODAY TIMES PEOPLE CANT AFFORD TO PAY BIG BUCKS FOR LITTLE PARTS. GM NEEDS TO EXTEND THE RECALL TO ALL 8.1 L REGARDLESS OF YEAR OR MAKE. I FOUND A WEB SITE THAT SOME BOAT MOTORS ARE DOING THE SAME THING 8.1 GM. CHEAP IF YOU FIX IT BEFORE YOUR OUT ON A ROAD TRIP. P.S. I HEARD ABOUT A OPENING ON THE HUMP BUT GM LINE WELDED IT UP. *TR

I HAVE A 2001 SUBURBAN 2500 8.1 L. 3/4 TON. THE ENGINE WOULD STALL WHILE DRIVING WITHOUT WARNING. IT HAS HAPPENED MANY TIMES INCLUDING IN THE MIDDLE OF AN INTERSECTION AND ON THE FREEWAY GOING AT FREEWAY SPEEDS INCLUDING HAULING A TRAILER. WHEN THIS OCCURS POWER STEERING AND POWER BRAKES ARE LOST WITH HOPES OF BEING ABLE TO COAST TO THE SIDE OF THE ROAD WITHOUT GETTING HIT. FOUND NHTSA RECALL # 07V521000 AND GM # 06083. THIS RECALL DESCRIBED MY VEHICLES PROBLEM EXACTLY. TOOK VEHICLE INTO DEALERSHIP MENTIONING RECALL, OUR VIN # IS NOT AFFECTED. DIAGNOSTIC SHOWED CRANKSHAFT POSITION SENSOR FAILURE EXACTLY LIKE THE RECALL. GM WOULD NOT COVER ANY EXPENSES BECAUSE VIN WAS NOT INCLUDED IN RECALL. AFTER REVIEWING OTHER COMPLAINTS, I SEE THAT THERE ARE OTHERS WHO HAVE HAD THE SAME ISSUE AND VIN #'S WERE EXCLUDED FROM THE RECALL. THIS RECALL SHOULD BE EXPANDED TO INCLUDED A WIDER RANGE OF VIN #'S OR AT LEAST INVESTIGATED FURTHER. TOO MUCH OF A COINCIDENCE AND TOO DANGEROUS OF A SITUATION TO LET THIS GO. *TR

I PURCHASED THIS VEHICLE NEW IN 2001. ON JULY 20, 2007 ON AN OUT OF TOWN FAMILY/WORK TRIP, I REFILLED THE FUEL TANK AND TRAVELED ANOTHER 88 MILES TO MY FINAL DESTINATION, UPON ARRIVAL I SMELLED GAS, BUT SAW NO PROBLEMS. THE NEXT MORNING I WAS SCHEDULED TO ATTEND AND EVENT AND WENT OUT TO START THE TRUCK AND FOUND A HOLE IN THE ASPHALT DRIVEWAY, APPROXIMATELY 3 FEET IN DIAMETER, AND DISCOVERED FUEL LEAKING FROM THE MIDDLE OF MY TRUCK. I REMOVED THE GAS TANK PROTECTIVE COVER AND FUEL SPILLED EVERYWHERE. I FOUND A LOCAL MECHANIC THAT TRAVELED TO MY LOCATION, HE AND 2 OTHERS WORKED ALL DAY AND FOUND THAT THE LOCK RING THAT HOLDS THE FUEL PUMP ASSEMBLY TO THE TANK WAS ONLY LIGHTLY CONNECTED. REPAIRS WERE MADE AND I TRAVELED BACK HOME. 8/13/07 MY WIFE FILLED THE TANK 3/4'S FULL AND THE TANK LEAKED FUEL ALL OVER AGAIN. THE FUEL IS LEAKING FROM THE TANK WHERE THE FUEL PUMP ASSEMBLY IS CONNECTED. *JB

IN A LETTER DATED NOVEMBER 7, 2007, GENERAL MOTORS (GM) REPORTED TO THE OFFICE OF DEFECTS INVESTIGATION (ODI) THAT IT WILL CONDUCT A SAFETY RECALL (07V-521) TO REPLACE THE CRANK POSITION SENSOR (CKP) IN APPROXIMATELY 12,000 MODEL YEAR (MY) 2001 CHEVROLET SILVERADO AND GMC SIERRA VEHICLES EQUIPPED WITH 8.1 LITER ENGINES MANUFACTURED ON OR BEFORE NOVEMBER 15, 2000.ACCORDING TO GM, THE CKP CAN FAIL INTERMITTENTLY OR PERMANENTLY.A PERMANENT CKP FAILURE WOULD RESULT IN AN ENGINE STALL WITHOUT RESTART.AN INTERMITTENT CKP FAILURE COULD CAUSE THE SERVICE ENGINE SOON LIGHT TO ILLUMINATE, THE VEHICLE TO RUN ROUGH OR THE ENGINE TO STALL BUT ALLOWS RESTART.AS A REMEDY, AN IMPROVED CKP WILL BE INSTALLED IN THE SUBJECT VEHICLES.THE RECALL CAMPAIGN WILL START IN DECEMBER 2007. DURING THE PRELIMINARY EVALUATION (PE06-016), AND THIS EA INVESTIGATION, GM AND ODI INDEPENDENTLY CONDUCTED DETAILED REVIEWS OF CERTAIN FIELD DATA TO UNDERSTAND THE NATURE AND RATE OF SUBJECT VEHICLE STALLING DUE TO CKP FAILURES.GM AND ODI REVIEWED GM'S WARRANTY CLAIMS FOR THE CKP WITH THE OBJECTIVE OF ASCERTAINING AN ESTIMATE OF THOSE CLAIMS REPRESENTING AN ENGINE STALL WHILE DRIVING.THE CKP WARRANTY CLAIMS WITHOUT VERBATIM TEXT WERE THE LARGEST SEGMENT OF WARRANTY CLAIMS.USING THOSE CLAIMS, GM SURVEYED VEHICLE OWNERS TO GATHER ADDITIONAL INFORMATION TO DETERMINE IF THE CLAIM WAS ASSOCIATED WITH A STALL WHILE DRIVING EVENT.BASED ON THE SURVEY, GM ESTIMATED THAT APPROXIMATELY 49% OF ALL WARRANTY REPAIRS FOR THE CKP INVOLVED A STALL WHILE DRIVING.ODI?S REVIEW OF GM'S SURVEY DATA PRODUCED A HIGHER ESTIMATE (71%) FOR STALL WHILE DRIVING.GM FURTHER ESTIMATED THE RATE OF STALL WHILE DRIVING FOR THE SUBJECT VEHICLES OVER TIME.IT ESTIMATED STALLING WHILE DRIVING RATES OF 1.6%, 4.6% AND 8.9% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY.ODI'S REVIEW OF THE GM'S SURVEY DATA FINDS HIGHER ESTIMATED STALL WHILE DRIVING RATES OF 2.2%, 6.8% AND 13% AT 1, 3 AND 6 YEARS IN SERVICE RESPECTIVELY. ODI ALSO CONDUCTED A SURVEY OF VEHICLE OWNERS USING CONSUMER COMPLAINTS REPORTED TO BOTH ODI AND GM.THE OBJECTIVE WAS TO ASCERTAIN THE POTENTIAL SAFETY CONSEQUENCES OF AN ENGINE STALL DUE TO THE ALLEGED DEFECT.WITH RESPECT TO THE ABILITY TO RESTART THE VEHICLE AFTER A STALL, 11% REPORTED IMMEDIATE RESTART, 69% REPORTED DELAYED RESTART AND 20% REPORTED NO RESTART.OVER HALF NOTED AT LEAST ONE ENGINE STALL INCIDENT AT SPEEDS IN EXCESS OF 40MPH. ABOUT ONE-THIRD NOTED THE VEHICLE WAS STRANDED EITHER PARTIALLY OR FULLY IN A LANE OF TRAFFIC AFTER THE ENGINE STALL.ALL OF THE CONSUMERS SURVEYED NOTED MULTIPLE STALLING EVENTS PRIOR TO PROPER DIAGNOSIS AND REPLACEMENT OF THE CKP.BASED ON GM'S DECISION TO CONDUCT A SAFETY RECALL, THIS INVESTIGATION IS CLOSED.
