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.

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.

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
