2015 Chevrolet Silverado 2500 fuel system complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
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 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.
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.
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.
Def tank heater failure. Restricting speed. Dangerous on highway and trips. Def fluid restrictions because of soot build up.
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.
