2003 GMC Yukon Xl 1500

I PULLED OUT OF MY DRIVEWAY IN MY 2003 GMC YUKON XL AND ONLY WENT A SHORT DISTANCE WHEN I NOTICED THE ENGINE WAS VERY SLUGGISH AND THE DIC SHOWED "REDUCED ENGINE POWER". I TURNED AROUND AND WENT HOME. I SHUT THE VEHICLE OFF. WHEN I STARTED IT UP A LITTLE WHILE LATER IT WAS FINE. I CALLED THE DEALERSHIP WHERE I PURCHASED IT AND THEY SAID THAT THIS WAS COMMON AND IT WAS DUE TO REFUELING WITH THE VEHICLE RUNNING OR A LOOSE GAS CAP...NEITHER OF THESE HAD HAPPENED IN MY CASE. THE NEXT DAY I HAD MY THREE CHILDREN IN THE VEHICLE AND WAS DRIVING SOUTH ON RT. 95 WHEN THE VEHICLE JUST SHUT DOWN. I LOST ALL ABILITY TO MANEUVER THE VEHICLE. THE VEHICLE WOULD NOT START AND HAD TO BE TOWED. THE MECHANIC THAT TOWED IT READ THE DTC'S AND FOUND THE FOLLOWING: -CLASS 2 DATA LINK MALFUNCTION. - BODY CONTROL MODULE. - PCM TO TAC MODULE SERIAL DATA CONNECTION. I PLACED A CALL TO GMC ON 9/2 TO REPORT THE PROBLEM AND THE DANGER IT HAD PLACED MY FAMILY IN. THEY TOLD ME IT HAD TO GO TO A DEALERSHIP FOR AN OFFICIAL DIAGNOSIS. AFTER RESEARCHING THIS ISSUE I HAVE FOUND THAT THE SAME PROBLEM HAS OCCURRED NUMEROUS TIMES W/ OTHER YUKONS AS WELL AS 2003 CHEVY AVALANCHES. AFTER READING THE TECHNICAL SERVICE BULLETINS REGARDING THIS ISSUE IT IS VERY APPARENT THAT GMC IS FULLY AWARE OF THIS VERY SERIOUS SAFETY ISSUE BUT HAS CHOSEN TO IGNORE IT PUTTING MILLIONS AT RISK EVERY DAY. SOMEONE NEEDS TO ADDRESS THIS BEFORE MORE PEOPLE GET HURT. *NM

I HAVE A 2003 GMC YUKON XL WHICH BOTH FRONT WHEEL BEARINGS FAILED AT THE SAME TIME AT ~51,280 MILES. THESE ARE SEALED BEARINGS THAT WERE SUPPOSED TO LAST THE LIFETIME OF THE VEHICLE. I WAS ABLE TO AVOID A CATASTROPHIC FAILURE BY REPLACING BOTH FRONT WHEEL BEARING ASSEMBLIES, $692.49, WHEN I HEARD THE BEARING GRINDING NOISE. THE MECHANIC AT THE GM DEALER TOLD ME HE REPLACES THE BEARING ASSEMBLIES ON TWO TO THREE VEHICLES A WEEK. *JB
