NHTSA Complaint #10021508 — 1997 GMC YUKON

I HAVE HAD TO HAVE MY 1997 GMC YUKON TOWED THREE TIMES IN THE PAST 6 MONTHS DUE TO ENGINE FAILURE WHILE DRIVING. AT FIRST, THEY THOUGHT IT WAS THE TRANSMISSION. THE TRANSMISSION WAS REPLACED. THE SECOND TIME, I WAS DRIVING AND THE ENGINE STARTED MISSING, THEN JUST DIED. NO STEERING, NOTHING. IT WAS TOWED TO THE SHOP AGAIN TO HAVE THE TRANSMISSION RECHECKED. GOT THE YUKON BACK AFTER A MONTH, DROVE IT HOME (ABOUT 90 MILES)...IT WAS FINE. THEN THE SECOND DAY AFTER GETTING IT BACK, IT AGAIN STARTED JERKING, MISSING, AND THEN DIED. I WAS ON A HILL IN TOWN WHEN IT STOPPED. MY YUKON STARTED ROLLING BACKWARDS, AND I HAD TO FORCE THE WHEEL TO SHARPLY STEER IT INTO A PARKING LOT. I ALMOST HIT SEVERAL CARS THAT DIDN'T KNOW THE VEHICLE HAD LOST POWER. IT HAS ONCE AGAIN BEEN TOWED TO THE SHOP. WHAT IS CAUSING IT TO SUDDENLY MISS THEN DIE? *JB
