2007 CHEVROLET SILVERADO 3500 Engine Problems

TL* THE CONTACT OWNS A 2007 CHEVROLET 3500. WHILE DRIVING 65 MPH, THE VEHICLE WOULD SLOW DOWN TO ABOUT 30 MPH WITHOUT WARNING. THE CONTACT STATED THAT IT FELT AS IF THE BRAKES WERE APPLIED. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE FUEL INJECTORS NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VIN WAS UNKNOWN. THE FAILURE MILEAGE WAS 30,000. UPDATED 02/05/16*LJ *CN

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...
