ENGINE SHUTS DOWN WHILE DRIVING: I HAVE A YUKON XL 2002. OVER THE PAST 6 MONTHS THE ENGINE WOULD SUDDENLY SHUT DOWN WHILE THE CAR IS BEING DRIVEN. IT HAS OCCURRED AT HIGH SPEED AND AT LOW SPEED. I HAVE TAKEN IT BACK TO THE DEALER NO LESS THAN 5 TIMES AND THE PROBLEM PERSISTS. THIS REPRESENTS A MAJOR DANGER AS WHILE ON THE HIGHWAY, WHEN THE ENGINE SHUTS DOWN THE CAR BECOMES DIFFICULT TO MANEUVER AND MOVING OUT OF THE HIGHWAY TRAFFIC HAS BEEN EACH TIME EXTREMELY DANGEROUS TO ME AND TO OTHER DRIVERS. *TR

TL*THE CONTACT OWNS A 2002 GMC YUKON XL. THE CONTACT STATED THAT THE VEHICLE WOULD NOT START. IN ADDITION, THE VEHICLE WOULD STALL INTERMITTENTLY WHILE DRIVING AT VARIOUS SPEEDS. THE ENGINE WOULD COMPLETELY SHUT OFF. OCCASIONALLY, THE VEHICLE WOULD IMMEDIATELY RESTART, BUT OTHER TIMES, IT WOULD TAKE A WHILE. THERE WERE NO WARNING INDICATORS PRIOR TO THE FAILURE. THE VEHICLE STALLED THE MOST DURING DECELERATION. THE VEHICLE WAS TOWED ONCE AND THE DEALER MADE SEVERAL ATTEMPTS TO CORRECT THE FAILURE, BUT HAS BEEN UNSUCCESSFUL. THE CURRENT MILEAGE WAS 54,409 AND FAILURE MILEAGE WAS 14,523. UPDATED 04/29/08. *LJ THE CONSUMER STATED THE CRANKSHAFT POSITION SENSOR WAS REPLACED.

MY GMC YUKON 2500 WITH THE 8.1L STALLS WHILE DRIVING. THIS IS UNEXPLAINABLE AND UNREPEATABLE. THIS HAS OCCURRED PROBABLY 6 OR 7 TIMES AND IS A REAL DANGER AS YOU LOOSE POWER STEERING AND BRAKES. I BELIEVE IT IS THE CAM POSITIONING SENSOR. WHAT IS MY RECOURSE TO HAVE FIXED BY MANUFACTURER. *TR

CAR STALLS WHILE TRAVELING DOWN HIGHWAY, OCCURS AT LEAST ONCE ON EACH TRIP. TIME OF OCCURRENCE IS BETWEEN 3 AND 30 MILES. SEVERAL TIMES IT HAS STALLED AND WOULD NOT RESTART WHILE IN MOTION, THOSE TIME TOOK SEVERAL MINUTES TO FIVE MINUTES TO GET IT RESTARTED. PROBLEM STARTED SIX MONTHS AGO AND HAS PROCEEDED GETTING WORSE. HAS BEEN SERVICED BY DEALERSHIP 5 TIMES SINCE FIRST TIME. THEY HAVE REPLACED SEVERAL ITEMS THAT HAVE NOT CORRECTED THE PROBLEM. WE HAVE HAD SEVERAL NEAR REAR END CRASHES AND SCARY MOMENTS WHEN ON THE INSIDE LANE OF AN INTERSTATE PULLING A 16 FT TRAILER. *JB

DT*: THE CONTACT STATED WHILE TRAVELING 75 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE RESTARTED AND THE MANUFACTURER WAS ALERTED. UPDATED 11/9/2006 - THE VEHICLE STALLED THREE TIMES IN ONE DAY AND ANOTHER TIME ABOUT 16 MONTHS AGO. THE CONSUMER WAS TOLD BY A SERVICE MANAGER THAT THE PROBLEM WAS WITH A COMPUTER RING IN THE KEY SWITCH ASSEMBLY. *NM

ORIGINAL PROBLEM: MY 2002 YUKON XL WAS RUNNING POORLY WHEN THE WEATHER TURNED COLD - BELOW 30 DEGREES. PROBLEM DIAGNOSED AS FAULTY INTAKE GASKETS DUE TO IMPROPER DESIGN. SECOND PROBLEM: IT BECAME HARD TO START, AND A COUPLE OF DAYS LATER, IT WOULD NOT START AT ALL. PROBLEM DIAGNOSED AS FAULTY FUEL PUMP. BOTH PROBLEMS ARE BECAUSE THEY WERE DESIGNED FOR USE WITH ETHANOL OR UNLEADED GAS. I ONLY USE UNLEADED (NEVER HAVE SEEN A STATION THAT SELLS ETHANOL). IF YOUR GM VEHICLE HAS A 5.3L V8 ENGINE, AND THE VIN HAS A Z IN THE 8TH POSITION, BE AWARE THAT THIS MIGHT HAPPEN TO YOUR VEHICLE. IF NOT UNDER WARRANTY, IT IS VERY COSTLY! THE GASKETS AND THE FUEL PUMP ALONE COST OVER $630. LABOR OVER $500. *NM

Mileage: 57,800

DT: THE CONSUMER BELIEVES THAT THERE ARE ELECTRICAL PROBLEMS WITH THE GMC. THE WATER PUMP WAS OUT, THE RADIO HAS QUIT WORKING 5 TIMES, AND HAS BEEN REPLACED 4 TIMES, THE WINDOWS ON THE PASSENGER QUIT, AND THE REGULATOR WAS REPLACED 4 TIMES. THIS HAS HAPPENED AT 35,000 MILES. *AK
