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.

Lost power at 60 mph on 5 lane freeway on 6% grade with no warning when turbo charger variable vane got stuck. Had to navigate through 2 lanes of trucks to get into the emergency parking lane. Computer limited me to 15 mph. Computer designed to do this. No accident happened due to some very courteous truck drivers. It seemed like a safety issue to me, but don't know if it is important enough for your to investigate.
