2011 Chevrolet Silverado 2500 FUEL/PROPULSION SYSTEM

Engine suddenly stopped running while driving and could not be restarted. It was towed to a local diesel repair shop. Diagnostics showed a catastrophic failure of the high pressure fuel pump which polluted the complete fuel system with metal.

WHILE DRIVING IN EXCESS OF 55 MPH ON I 95, MY 2011 CHEVROLET SILVERADO 2500 STALLED WITHOUT WARNING WHILE I WAS IN THE FAR LEFT PASSING LANE. NO POWER STEERING OR POWER BRAKES MADE IT EXTREMELY DIFFICULT TO CONTROL WHILE MOVING THROUGH 4 LANES OF TRAFFIC TO GET TO THE SHOULDER. I WAS UNABLE TO RESTART THE VEHICLE AND HAD TO HAVE IT TOWED TO A GARAGE. I WAS INFORMED THE CP4 FUEL INJECTION PUMP HAD FAILED AND REPAIRS WILL BE IN EXCESS OF $8,000 BECAUSE THE ENTIRE FUEL DELIVERY SYSTEM WAS CONTAMINATED AND NEEDS TO BE REPLACED.

TL* THE CONTACT OWNS A 2011 CHEVROLET SILVERADO 2500. WHILE DRIVING APPROXIMATELY 35 MPH, THE VEHICLE STALLED. THE CONTACT COASTED THE VEHICLE TO THE SIDE OF THE ROAD. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS TOWED TO THE CONTACT'S RESIDENCE AND THEN TOWED TO BOMNIN CHEVROLET (8455 S DIXIE HWY, MIAMI, FL 33143). THE DEALER DIAGNOSED THAT THE CP4 FUEL PUMP FAILED AND NEEDED REPLACEMENT. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 123,000.

AN ARTICLE IN TRAILER LIFE (MAY, 2019) IDENTIFIED THAT THE BOSCH CP4.2 HIGH-PRESSURE FUEL-INJECTION PUMP IS SUBJECT TO CATASTROPHIC FAILURE. IT POINTS OUT THIS IS A COMMON FAILURE, A DESIGN ISSUE AND WILL COST MANY $1000'S TO REPAIR. IT HAS BEEN CALLED A "FATAL FLAW". IT SHOULD BE REPLACED WITH A UNIT THAT IS RELIABLE BY THE MANUFACTURER IF THIS IS A COMMON PROBLEM. MICHIGAN S&S MOTORSPORT STATES THIS IS A KNOWN PROBLEM AND IS COMMON TO 2011 TO 2016 DURAMAX DIESEL SILVERADOS USING THE BOSCH CP4.2 FUEL-INJECTION PUMP.
