NHTSA Complaint #10195291 — 2002 CHEVROLET SUBURBAN 2500

VEHICLE WOULD STALL WHILE DRIVING WITHOUT WARNING AT ALL DIFFERENT SPEEDS INCLUDING HIGHWAY SPEEDS. VEHICLE WOULD SOMETIMES STALL 3 TIMES PER DAY, AND SOMETIMES NOT AT ALL IN A DAY. LOSS OF POWER STEERING AND POWER BRAKES RESULTED WHICH SOMETIMES PRESENTED A CHALLENGE TO SAFELY GET THE VEHICLE OFF THE HIGHWAY OR ROADWAY WHILE COASTING TO A STOP. STALLS OCCURED SEVERAL TIMES WHILE TOWING A 5000 POUND BOAT AND ALSO OCCURED WHILE TOWING A 9000 POUND CAMPER TRAILER. TWO DEALERS LOOKED AT THE VEHICLE AND REPORTED FINDING NO CAUSE FOR THE STALLING. I FOUND AN AUTOMOTIVE INTERNET DISCUSSION FORUM WHERE MANY OTHER PEOPLE REPORTED THE SAME PROBLEM WITH THE 8.1L ENGINE. MANY OF THESE PEOPLE REPORTED THAT THE CRANKSHAFT POSITION SENSOR WAS THE CAUSE, AND THAT REPLACING THE CRANKSHAFT POSITION SENSOR WOULD FIX THE PROBLEM. I TOOK THE VEHICLE BACK TO THE DEALER TO HAVE THE SENSOR REPLACED, AND THE VEHICLE HAS NOT STALLED AT ALL SINCE THE SENSOR WAS REPLACED.*AK
