- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra vehicles, and model year 2015 GMC Yukon and Chevrolet Suburban and Tahoe vehicles.

- Risk
- If the transfer case switches to neutral while the vehicle is parked and the parking brake is not in use, the vehicle may roll away increasing the risk of injury to bystanders.

Electrical system: software
- What is wrong
- General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Silverado and GMC Sierra, and 2015 Chevrolet Tahoe and Suburban vehicles equipped with a base radio and an internal amplifier.

- Risk
- Without an audible indicator, the driver may not be aware that the driver's door is open while the key is in the ignition, increasing the risk of a vehicle rollaway.

The vehicle lights are very dim even with the high beams on. While driving at night can barely see in front of me. These are a hazard to me and others, since not being able to see a good distance in front of the vehicle makes hard to see pedestrians, animals or debris in the road at night.
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.
Can not see the road with the light output with these factory headlight
The headlights are too dim and are unsafe. In my 50+ years of driving, I have never experienced headlights so bad. I live in a dark rural area without any streetlights and lots of bicyclists and deer. I have already had many near misses on rural roads, and fear it's only a matter of time before an accident happens.
The headlight output at night, particularly in rural back road areas is less than adequate. Poor really. I originally had moisture issues in both headlamp housings, had both headlamp housings replaced and the lighting seemed to be better, however not very much. The headlights seem to have dark spots in them and only light up certain parts of the road in front of me, and never much to the side of the roadway. I feel this is by far the worst lighting output of any vehicle I have ever owned, and actually feel a little unsafe driving at night. I most definitely cannot travel at higher speeds during the night as I feel like I cannot see nearly good enough. I have simply "dealt" with the issue since buying the truck in december 2013, thinking there was no fix to it and the dealership said they have not heard of this issue before.
