general problems of the 2015 Chevrolet Silverado 2500

My pickup truck has a duramax diesel engine with a cp4 diesel injection pump. That pump has not failed yet in my truck. However it has been known to fail in numerous other gm vehicles with duramax engines and when it does fail the engine comes to a complete stop and cannot be restarted. This is a potentially hazardous even fatal situation. Repair if the pump fails is very expensive - $12,000 to $14,000 in some cases. I would like gm to replace the injection pump at my dealership to ensure this known failure does not occur. My pickup truck is otherwise in excellent condition.

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.

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.

Fuel pump failure while driving highway speed 70mph pulling a trailer. Engine light came on and engine went to limp mode for a few seconds then completely shut down without warning while still going at least 60. Lost power steering and power brakes. Service center confirmed the code for "low fuel rail pressure" and did the repair. I have retained the cp4 pump for analysis. I was very lucky to not crash my truck.

Fuel pump cracked under normal wear and tear under 60,000 miles leaving me stranded for a week and costing $1600 to replace. Transmission is very unresponsive and soupy, sometimes it kicks in late, other times not at all. Ive read this is a known issue with my vehicle.

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.

The fuel injection pump malfunctioned causing the truck to shut down going down the highway. It was taken to a professional and was confirmed to be an issue with these vehicles. There was no warnings at all. The cost to repair was $8000. 00.

The bosch cp4 pump failed at 128,360 miles sending metal shavings through the fuel system and engine. There was no warning. I was driving and the truck completely stopped. I had purchased a 125,000-mile extended warranty and this was just right out of warranty. Chevrolet and gm has not yet recalled this pump, also when it was replaced by the dealership (jim keras Chevrolet - memphis, TN), it was required to be replaced back with the defective cp4 pump vs going back to the cp3 pump. My safety was put at risk as it stopped while driving. Luckily I was on a road that did not have traffic. This happened in 2020, I am currently at 187,000 miles and I am sitting on a ticking time bomb unless Chevrolet recalls and replaces the bosch cp4 fuel pump with something else. There are thousands of individuals affected by this issue and only 7 states have been certified for a class action lawsuit which gm just settled for those 7 states. This is a us wide issue, not just seven states. I contacted gm during the incident and the report number given was: service request number: 9-6145466811 phone number: 1-866-790-5600 -or- 1-866-790-5700 extension: 5921084.

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.

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 1400�f 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.
