The contact owns a 2015 GMC Sierra 2500. The contact stated that while driving at 45-48 MPH, the check engine warning light illuminated. The contact used a vehicle scanner and retrieved diagnostic test code P0420 that indicated an efficient operating below threshold, and the contact cleared the code. Additionally, the contact stated while the exhaust filter was being cleaned, an unknown message was displayed. Upon clearing the code, the check engine warning light illuminated again. The vehicle was taken to the local dealer, who informed the contact that there was no warranty coverage. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 83,000.

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.

I was driving at approximately 40 MPH on a busy city street, I was going to be getting on the freeway where my speed would be in excess of 70MPH. Suddenly without any warning, my 2015 GMC Sierra 2500 HD Duramax died. I had no power at all which means no steering, brakes, etc. I was able to get the vehicle off the road with brute force. After the vehicle was towed to the dealership they inspected it and said that the Fuel Injector Pump failed which put metal throughout the whole fuel injection system (>$7000 repair). While doing some additional research on the Internet I find out that this is a common problem for the 2011-2016 GM Duramax trucks, because GM chose to use a Bosch Fuel Injector Pump which is not suitable for use with US low sulphur diesel fuel.
