“Truck has a CP4 injection pump and they go bad and cost $15,000-$20,000 to repair and if that happens I owe money on the truck and would have to get a loan or figure something out and still have to make a payment on something I can't even drive! They need to recall it and swap them out to a CP3 and be done with it. Why wait until it cost 10s of thousands of dollars when they can get it done for $3,500 at the most?”Owner report · Fuel/Propulsion System · Nov 2023
“Shifting started to make a loud clunking sound. Then the vehicle wouldn't shift out of 3rd gear. The engine check light came on and the code determined it to be a faulty transmission control module (TCM). When looking at the TCM, I also noted that the TCM was very hot and the nearby cable cover had melted. When researching the issue, it was discovered that GMC Sierra 2500 and 3500, years 2009 - 2015 were having this same issue all over the continent. Resulting in a massive back order and leaving drivers stranded. There was no warning lights or sounds before my power train froze up.”Owner report · Power Train · Sep 2023

The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 189,458 and the contact stated he discovered on Carfax that mileage was 188,052; however, the contact discovered that the mileage was 112,708.”Owner report · Electrical System · Aug 2023
“While driving down the highway at 60 mph, the truck stumbled then completely died. After coasting to a stop truck would not restart. Towed to a repair shop to find out the Bosch CP 4 fuel pump exploded and contaminated the whole fuel system with metal shavings. A very expensive and lengthy repair. GM has known there is issues with these parts, but has failed to recall and fails to cover repair costs. Other manufacturers using the same part have issued recalls. While I was able to safely the get vehicle to the side of the road, the failure could've resulted in an accident causing personal injury or property damage.”Owner report · Fuel/Propulsion System · Apr 2023
