WHILE DRIVING THE SERPENTINE BELT TENSIONER BROKE FROM ITS MOUNTING AND RESULTED IN LOSS OF POWER STEERING AND OTHER COMPONENTS INCLUDING CHARGING OF THE BATTERY. THE ALTERNATOR ALSO SHORTED OUT. THE MANUFACTURER AND THE DEALER WERE NOTIFIED. *AK THE CONSUMER WAS TOLD THAT THE WARRANTY NOT LONGER COVERED THE BELT. THE BRAKES SHUTTERED WHILE BRAKING FROM 60 MPH. THE DEALER REPLACED THE FRONT BRAKE PADS AND RESURFACED THE ROTORS. *NLM

TRUCK PULLS WHEN BRAKING. TBS FIX IMPLEMENTED WITH LITTLE TO NO IMPROVEMENT. LAST TIME AT DEALER, DEALER SAID GMC HAS PROBLEM WITH 3/4TON SUBURBAN BRAKES BUT DOESN'T HAVE FIX. NOTHING HE CAN DO. TRUCK HAS HAD COMBINATION VALVE REPLACED, REAR SHOES REPLACED, FRONT PADS REPLACED (5X TOTAL), CALIPERS REPLACED, ROTORS REPLACED, TIE RODS REPLACED, IDLE ARM REPLACED, STEERING BOX AND PITMAN ARM REPLACED, FRONT BRAKE HOSES REPLACED, CONTROL ARM BUSHINGS REPLACED, AND ALIGNED SEVERAL TIMES WITH NO FIX TO THE PROBLEM. BRAKING AT HIGHWAY SPEEDS IT IS VERY DANGEROUS. YOU DON'T KNOW WHICH WAY THE VEHICLE WILL GO AND HOW HARD IT WILL TRY TO GET THERE. AS AN ENGINE DESIGNER I FIND IT AMAZING THAT GM HAS A HANDLING/SAFETY ISSUE OF THIS MAGNITUDE. THIS IS A BIG TRUCK TO HAVE SUCH A CONTROLABILITY PROBLEM. PLEASE HELP. A SHAULL
