NHTSA Complaint #11208294 — 2014 CHEVROLET SILVERADO 3500

THE 2014 CHEVY SILVERADO 3500HD DURAMAX DIESEL COMES EQUIPP ED WITH THE BOSCH CP4 INJECTION FUEL PUMP. THIS PUMP IS PRONE TO FAILURE AT ANYTIME MILEAGE WISE. THE PUMP WAS USED IN EUROPEAN DIESEL ENGINES WITH SUCCESS SINCE THEIR FUEL HAS A HIGHER CONTENT OF LUBRICITY. DUE TO THE ULTRA-LOW SULFUR FUEL MANDATED FOR US DIESEL ENGINES THIS PUMP HAS A HISTORY OF CATASTROPHIC RESULTS WHEN USED IN THE 2011-2016 DURAMAX 6.6L CHEVY ENGINES.METAL TO METAL WEAR CAUSES SMALL METAL FRAGMENTS TO ENTER THE FUEL SYSTEM THEREBY CAUSING ENGINE FAILURE. THIS EVENT CAN HAPPEN WITHOUT WARNING. IF THE ENGINE HAS STOPPED WHILE IN MOTION THIS PRESENTS AN ACCIDENT WAITING TO HAPPEN. MY CONCERN IS THAT I TOW A 14000LB RV 5TH WHEEL TRAILER WITH MY TRUCK. HOW CAN IT BE STOPPED SAFELY WITH OUT THE ENGINE PROVIDING POWER TO THE BRAKING SYSTEM?. THIS ENGINE IS VERY POPULAR AMONG RV'ERS, BOATERS, FLATBED HAULERS ETC; BASICALLY ANYONE MOVING A HEAVY LOAD DOWN THE HIGHWAY.IF THIS INCIDENT HAPPENS WHEN THE VEHICLE IS OUT OF WARRANTY THE REPAIRS CAN COST $8 TO 12K. MANY WEBSITES CONTAIN INFORMATION ABOUT THE CP4 FAILURE. MY SON HAD 2 SUCH VEHICLES IN A SMALL TRUCKING FLEET COSTING HIM OVER $20K TO REPAIR. I FEEL GENERAL MOTORS SHOULD ISSUE A RECALL OR PROVIDE OWNERS OF THIS VINTAGE TRUCK ADDITIONAL COVERAGE. THIS PUMP WAS ALSO USED BY FORD & DODGE IN THE MID 2012-2014 WITH THE SAME RESULTS. THE MAY 2019 ISSUE OF "TRAILER LIFE" MAGAZINE CONTAINS AN ARTICLE ABOUT THE BOSCH CP4 ON PAGES 77-81. TO DATE MY VEHICLE HAS NOT HAD THIS PROBLEM YET. MY SONS TRUCKS BLEW UP IN JULY 2017
