2015 Chevrolet Silverado 2500 FUEL/PROPULSION SYSTEM

on [XXX] my 2015 Chevy 2500 crew cab LTZ Duramax with 50,959 miles stopped running going down a large hill, Barely made it off the road coasting into a Fire department parking lot. 2nd failure occurred while driving on a main route in WV. At 66,600 miles [XXX], was almost rear ended because truck again just stopped running going 50 mph around a turn. Diesel fuel was pouring onto the hot engine second occurrence. I don't know how the truck didn't catch on fire. Thank [XXX] I wasn't towing my 14,500 lb fifth wheel either time. Both incidents were because of a CP4 injection Pump Failure completely taking out and polluting the entire fuel system. Per GM service department in Wintersville, Oh. I no longer feel safe driving the truck and wouldn't even consider towing with it again. Too dangerous for me and my family !! I am fearful this could end up causing serious injury or death !! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

CP4 fuel pump caused the vehicle to shut down and stopped running.

I was driving north on Va. 10 in Hopewell when my engine unexpectedly, with no warning, quit. I was in heavy traffic with no power brakes or steering and had to maneuver to the right lane and find an area that was off the road that I could get into. Fortunatley there was a parking lot that I managed to coast into. The truck would not re-fire so I called for a wrecker

Per a report from Car Complaints, the lawsuit alleges that 2011- through 2016-model-year Chevy Silverado and GMC Sierra pickups equipped with the 6.6L V8 LML turbodiesel Duramax engine are equipped with defective Bosch CP4 fuel pumps that are more fragile and prone to wear than previous CP3 fuel pumps. According to plaintiffs, the defective CP4 pumps can be destroyed by U.S. diesel fuel, which is allegedly “drier” than diesel fuel in other countries. The lawsuit alleges that U.S. diesel fuel does not provide adequate lubrication for the CP4 fuel pump. The lack of lubrication can lead to internal fuel pump damage and result in metal shavings that damage the pump, the fuel system, and the GM Duramax engine as well. This damage can lead to the truck stalling and losing power, and may require the vehicle to be towed to a shop, leaving customers with big repair bills. The lawsuit goes on to allege that GM was aware that the Duramax engines and related fuel pumps were defective prior to selling affected vehicles, but declined to notify customers. Rather, GM allegedly concealed that the defective CP4 pumps may be destroyed by U.S. diesel fuel.

CP4 failure, caused metal fragments to go throughout fuel system and tank. Entire fuel system had to be replaced and tank cleaned out. CP4 failed in the middle of my drive home, stalling the truck in the middle of an intersection. Luckily had enough momentum to roll and pull over to the side of the road.

CP4 pump failed sending metal through out fuel system. Pump, fuel system flushed, injectors all need replaced. Truck stalled in motion. Thankfully I was able to safely pull over without accident occuring.

WHILE DRIVING, THE VEHICLE STUTTERED AND SKIPPED DOWN THE ROAD. WHEN I CAME TO A STOP THE TRUCK IT WOULD NEVER TURN ON AGAIN. THE TRUCK WAS HAVING WHAT'S CALLED A CRANK NO START PROBLEM WHERE IT WOULD CRANK OVER, BUT NOT START. THIS IS A FAILURE OF A CP4 PUMP THAT IS CONSIDERED THE WRONG PART AND COMMON KNOWLEDGE FAILURE TO CHEVORLET AND IS EXTREMELY EXPENSIVE TO FIX. *TR

DEF TANK HEATER FAILURE. RESTRICTING SPEED. DANGEROUS ON HIGHWAY AND TRIPS. DEF FLUID RESTRICTIONS BECAUSE OF SOOT BUILD UP.

FUEL GAUGE MEASURES EMPTY CAUSING DANGER OF RUNNING OUT OF DIESEL ON HIGHWAY. EVEN AFTER COMPLETE FUEL UP, THE DASHBOARD NEEDLE AND ELECTRONIC READERS IS STILL MARKING EMPTY. THERE HAS BEEN A PREVIOUS RECALL ON THIS ON PREVIOUS MODELS. MY 2015 ONLY HAS 60K MILES AND IT SENSORS OR FLOATERS ARE NOT WORKING. VERY DANGEROUS TO RUN OUT OF FUEL WHEN TOWING ON HIGHWAY.

THE DEF FLUID INDICATER IS STUCK AT 24%, THERE ARE MANY INSTANCES ON THE INTERNET OF THE SAME VEHICLE WITH THE SAME PROBLEM, SOME DEALERS FIX FOR FREE WITH A SIMPLE SOFTWARE UPGRADE, OTHER LIKE MINE WANT TO CHARGE ME DIAGNOSTICS AND MECHANICS TIME RUNNING INTO A COUPLE HUNDRED DOLLARS, WITH SO MANY VEHICLES HAVING THIS AND GM WON'T DO ANYTHING ABOUT IT, BEEN ON THE PHONE TO GM SEVERAL TIME WITH NO HELP. WITH THIS STUCK AT 24% YOU COULD RUN LOW ON DEF FLUID AND NOT KNOW IT AND THE TRUCK WILL LOSE POWER AND NOT LET YOU GO FASTER THAN 5 MILES AN HOUR. WHICH COULD CAUSE MANY SAFETY ISSUES. THERE EVEN IS A TSB ON THIS AND HOW TO FIX, BUT IF YOUR OUT OF WARRANTY IT'S MY COST. 22214 BULLETIN PIP4884Q C/S

WHILE DRIVING ON THE INTERSTATE, WE CAME TO A STOP AT A GAS STATION. WHEN AT A COMPLETE STOP WE STARTED SMELLING DIESEL FUEL, I ASSESSED THE VEHICLE UNDER THE HOOD AND UNDER THE TRUCK. IT WAS RAINING THAT DAY SO I COULDN'T TELL IF ANYTHING WAS LEAKING FROM THE UNDER CARRIAGE. WHILE DRIVING THE REMAINING TWO HOURS OF OUR TRIP, OFF THE INTERSTATE, WE CAME TO A RED-LIGHT, WHILE MAKING THE RIGHT TURN THE TRUCK GOT SIDEWAYS IN THE INTERSECTION. CONTINUING THE TRIP AND ALMOST HOME WE WERE ON A HIGHWAY GOING 65MPH, THE TRUCK GOT SIDEWAYS AND LOST TRACTION AGAIN. CONCERNED BECAUSE I HAVE MY WIFE AND 15 MONTH OLD IN THE TRUCK, I PULL OVER AGAIN TO ASSESS THE TRUCK. AT THIS POINT FELT OF THE TIRES AND THEY HAD A OILY SUBSTANCE ON THEM, CAUSING THE TRUCK TO NOT HAVE ANY TRACTION IN THE RAIN, I ALSO SEEN A SUBSTANTIAL AMOUNT OF FUEL LEAKING FROM AROUND THE TRANSMISSION. THE NEXT DAY I TOOK IT TO THE DEALERSHIP TO GET LOOKED AT. THEY INFORMED ME THAT THE HIGH PRESSURE FUEL PIPES HAD A SEVERE FUEL LEAK FROM THE CONNECTORS. THEY ALSO INFORMED ME THAT THERE WERE NO RECALLS OPEN ON THE VEHICLE. SO THEY ARE WANTING TO CHARGE ME OVER $1,300 TO REPAIR THIS, WHEN I FEEL LIKE THIS IS A HUGE SAFETY ISSUE CAUSED BY A LACK OF QUALITY ASSURANCE AND CONTROL. ALSO I AM FAIRLY CERTAIN THAT THIS USE TO BE A RECALL, AND THE DEALERSHIP SAID THAT THERE ARE NO OPEN RECALLS ON MY VEHICLE. I FEEL LIKE THERE SHOULD BE A RECALL ON THIS ISSUE ASAP, BEFORE IT KILLS SOMEONE.

FUEL LINE LEAK. TWO STEEL FUEL LINES WERE RUBBING AGAINST EACH OTHER CAUSING A FUEL LEAK. THIS IS A DIESEL PICK UP AND THE FUEL SYSTEM IS REPORTED AT 28,000 PSI OPERATION PRESSURE. THIS RESULTED IN A LEAK OF DIESEL FUEL THAT SPRAYED ONTO THE EXHAUST SYSTEM, WHICH CAN REACH TEMPERATURES IN EXCESS OF 1400F CAUSING A FIRE HAZARD. THE PROBLEM MANIFESTED AS A STRONG RAW FUEL SMELL IN THE CAB CAUSING AN INHALATION HAZARD. THIS WAS FOLLOWED BY SMALL STAINS IN MY PARKING SPOT. THE SMELL WAS NOT EVIDENT WHEN IN MOTION ON THE HIGHWAY ONLY WHEN STOPPED AND RUNNING. REPAIRS WERE MADE BY CASPER GMC DEALER IN CASPER, WY REPLACING THE FUEL LINES. THERE IS NO BUFFER (SUCH AS A TEFLON BUSHING) TO INSULATE SUCH EFFECTS.
