2014 Sierra 2500HD SN ([XXX]) Leaving on vacation towing camper with family Bosch CP4 fuel pump issue left me stranded on a HWY 9 just outside Clinton, AR which is a 2 lane HWY with no shoulder. The vehicle gave me no prior warning, dash board suddenly read power restricted followed immediately with complete power loss as I reached to top of hill. I was forced to steer and brake the truck and camper with no power, down the hill to prevent vehicles from passing at crest of hill. This left me and my family and numerous other drivers in a very dangerous situation as cars tried to pass. I had to open the hood and try to determine what was going on. I directed traffic until a Van Buren County, AR Sherriff-??s Deputy arrived scolding me to get the truck and trailer out of the highway. I was forced to unhook trailer in middle of HWY and leave it. All the while, vehicles passing in danger of head on collision because there was only one officer directing both sides of traffic. GM is aware of this issue that cost me $10336 at GM Dealership where repaired. Had I been aware, I would have had this replaced this Bosch CP4 part to prevent the unsafe conditions I encountered. One message came on dash, restricted power, and I was powerless. Final Bill stated -??Found Injection pump has come apart internally and has put metal through the system.-?? Internet search stated: According to InjectorsDirect.com, the 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year-range model. Failure of this CP4 pump is usually catastrophic, causing metal particulates to contaminate the entire fuel system. Please help this from happening to another person. These trucks are advertised showing families pulling campers traveling through mountains. That is exactly what my family was doing. I have additional documentation if needed.

We have problems starting the truck. You cant just turn the key it takes you wiggling it and pulling it out of the ignition some times flipping your key just a pain in the neck. Had it checked a year ago and they said it was the way we were sticking the key in and it wore down the key. So they made us a new key. It worked for a week or so and went right back to doing the same thing. So now we just dealt with it. Till now.... now it takes about 3 to 5 mins to get the key to turn and is out of warranty and I really think it was an ignition problem not a key problem. The truck only has 55,000 miles on it. Im so frustrated with my new truck. I have a 04 Suburban 223000 miles on it and still have no problems with turning the key.

Power steering failure. Power steering pump failed making the vehicle difficult to steer. Upon making a left turn at low speed steering failed and could not turn into my rv resort entrance off the main roadway. I had to come to a stop, continue backing up & pulling forward enough to try to complete turn. Had to have truck towed to a GMC dealer for service (power steering pump replaced). Leading up to failure, a few times the truck would be difficult to turn but it would last only a few seconds. After having it replaced it again happened over the weekend I will contact GMC in the morning. I am pulling a 15,000 lb. 5th wheel rv with this truck & not feeling confident in my safety after this incident.
