The high and low beams quit working while driving at night. This caused safety issue for myself and other drivers. Fuses good and bulbs good. Have seen multiple listings online about the same thing happening to other owners.

The headlights are dangerously dim, can't drive the vehicle comfortably at night. There seems to be no solution for fixing them. A TSB has been issued concerning this, but does little to address fixing the problem.

Back up lights and Tail light problems My Back up lights turn on when the headlights are turned on and do not shut off unless the headlights are off. Also, recently, the rear tail lights were burning out early and would last only two weeks. The source of the problem seems to be in the fuse box. There is no short in the system. It appears to be in the fuse box of the 2014 GMC Sierra 1500. Bulbs were replaced and burned out quickly. Replacement parts are expensive and this problem exists on other Chevrolet and GMC trucks.

The headlights on my pick-up are absolutely horrible and dangerous to drive with. I have even gone to the expense of having brand new ones intalled and they are no different in the lighting. I can barely see one car length ahead of me when driving at night, which is prohibiting me from using my pick-up for night time driving. This is ridiculous to have spent such a large sum of money for a vehicle and not be able to see driving at night. There should be a mandatory recall of this vehicle and the headlight system.

On several occasions spanning multiple years the truck loses power while braking and turning at slow speeds. On more rare occasions, but still numerous, the same problem occurs when braking at higher speeds without turning. The truck dash lights, media screen and headlights all dim or flicker as a ticking or popping noise is heard behind the dash much like an arching electrical wire. Most of the time when these scenarios happen the display on the drivers display screen reads stabiltrak warning. Also when the problem occurs while turning and braking at low speeds the truck will completely lose power and power steering as well as assisted braking. Once the truck comes to a stop the ignition, and all electrical systems are completely unresponsive like the battery is dead. In order to start the truck again, I have to get out of the truck, open the engine hood and oscillate both the negative and positive battery cables. Most of the time the truck will start up after doing this. Sometimes I have to use booster cables to get it to start. Neither the cables or the terminal connectors are loose as they have been inspected by a dealer service tech and a local mechanic.
