One problem related to power steering pump has been reported for the 2014 GMC Sierra. The most recently reported issues are listed below.
There is a extremely dangerous electrics issue with my 2014 GMC Sierra 1500 all terrain. In the last 18 months my truck has locked the steering at low speed while turning 8 times. (I could have easily broken a finger a lost control of my truck) . On 5 of the times I had steering issue the truck had no power to anything including key fobs for a period of 10 to 15 minutes. Then the truck will power up again. Fortunately these issues have occurred at low speed. This has happen 8 times in the last 18 months . It has been to dealership for service regarding this issue they changed the battery after only 18 months (10/2015) the issue occur again 2 days ago while traveling on the freeway at 70 mph my truck shut down no power then in less than a second it powered up again all the setting on my radio, climate control changed. That day I stopped to get gas got back in my truck pulled away from the pump the steering locked truck shut down again for 20 minutes. This truck is currently at a dealership they still can not diagnos the issue. I'm extremly concern that someone could be seriously injured or killed if this was to happen while operating this truck. I did see that may other owner of GMC Sierra have expressed similar concerns. The issues needs to be addressed immediately. As for myself I plan to this truck after the dealership attempts another repair.
