What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
I was stopped at a red light behind 2 other vehicles. A vehicle from behind struck me at appx 40 MPH and rammed me into vehicle in front of me. The cab of my truck filled with a white. "smoke". I was told by both firemen and wrecker driver airbags had activated but not deployed. My wife was with me. Both our seatbelts locked up as they should. Concern is had the airbag deployed it might have helped with back and shoulder injury. Maybe we would not have bounced around as much.
My son and I were driving my GMC sierra 2014 to his friends house before we crashed. My son was driving and has his learner's permit, however, had been driving for 4 months. At a fork in the road I told my son quickly to make a right rather than left and we crashed into an improperly grated wall of dirt causing the truck to go from 40 MPH to 0 with my son having his seatbelt on, but I did not. Neither airbags deployed and both of us sustained serious injuries.
The headlights on this truck are unsafe. They do not put out enough light on dark nights and especially on nights were there is rain. They do not reach beyond the edge of the road way past the fog lines,. Or extend that far up the road in front of the truck.
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.
