TRAVELING AT 60 MPH WHILE TOWING A 35' FIFTH WHEEL THE ENGINE STARTED TO SHUDDER A BIT. WHEN WE PULLED OVER AND PUT THE ENGINE INTO NEUTRAL THE ENGINE STOPPED RUNNING. WE TRIED TO START THE TRUCK BUT IT WOULD NOT TURN OVER BUT THERE WAS JUICE TO THE BATTERY TO RUN THE LIGHTS AND WINDOWS. AFTER BEING TOWED TO A LOCAL GARAGE, AS WE WERE OUT OF STATE, THEN TO ANOTHER IN OUR TOWN WE WERE INFORMED IT IS A BAD CRANKSHAFT AND A NEW ENGINE IS NEEDED. THE ENGINE HAS 55 THOUSAND MILES ON IT WITH NO MODIFICATIONS. AFTER MANY SEARCHES ON THE INTERNET I HAVE FOUND MANY CASES WHERE THIS HAS OCCURRED. I HAVE CONTACTED CHEVY AND THEIR RESPONSE IS IT IS OUT OF THE WARRANTY PERIOD, FIVE YEARS EVEN THOUGH IT IS WELL UNDER THE 100,000 MILE CAP. THIS NEEDS TO BE ADDRESSED AS IT COULD HAVE CAUSED A MAJOR ACCIDENT HAD WE NOT BEEN IN THE RIGHT LANE AND BEEN ABLE TO PULL OVER BEFORE LOSING COMPLETE POWER ON A MAJOR HIGHWAY.

OUR 2007 CHEVROLET 3500 4 X 4 WITH A 6.0 GAS ENGINE HAS FAILURE IN THE EXHAUST MANIFOLD BOLTS AND IS CAUSING NOISE AND EMISSION ISSUES IN AND OUTSIDE THE CABIN AND IS AFFECTING HORSE POWER. OUR TRUCK HAS NOW 13,000 MILES ON IT! THIRTEEN THOUSAND. IT IS WELL CARED FOR AND LITTLE USED, THERE IS NO EXCUSE THAT WE FACE A THOUSAND DOLLAR OR MORE BILL TO REPAIR A UNIT THAT IS A LONG WAY FROM BEING A USED UNIT. WE KNOW OF MANY NOW, THAT HAVE THIS ISSUE, OUR FRIEND SAID HE WOULD NOT PAY THE DEALER TO DO IT FOR HIS TRUCK, THERE IS NO SERVICE BULLETIN AND NO RECALL, BUT IT WAS AFFECTING EVERYTHING, AND YOU COULD NOT GAIN ACCESS TO THE BROKEN BOLTS UNLESS YOU TORE OUT THE TOP END OF THE MOTOR, SO HE REMOVED THE MOTOR AND REBUILT THESE PARTS HIMSELF, IT COST HIM HE SAID $700.00 TO DO IT HIMSELF. HE IS STILL MAD ABOUT IT. WE ARE WRITING YOU IN HOPES THAT YOU MAY INVESTIGATE AND HELP, THERE ARE EMISSION VIOLATIONS IN MANY STATES DUE TO THIS, AND THERE CAN BE A FIRE, IT CAN AFFECT THE SENSORS AND WILL TRIGGER CODES CAUSING ENGINE LIGHT TO REMAIN ON. THIS PROBLEM AFFECTS NEARLY 7 OR 8 YEARS OF GM TRUCKS, 4.8, 5.7 AND THE 6.0 SIZE ENGINES. AT FIRST IT WAS NOT TOO BAD, BUT IT HAS GOTTEN WORSE IN THE PAST FEW THOUSAND MILES. THE MILEAGE OF SEVEN THOUSAND IS MY APPROXIMATION OF WHEN I FIRST HEARD IT, I THOUGHT IT WAS EXHAUST, BUT I THOUGHT A PROTECTIVE PLATE OVER THE MUFFLER OR SOMETHING, NO WAY DID I THINK THE BOLTS OF THE MANIFOLD WERE BREAKING. PLEASE HELP US OUT ON THIS. *TT
