Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

The headlights on the truck are not as bright or as effective as they should be when traveling in the dark. I am forced to use the high beam far more than I would normally do in my car. Even with the upgrade, the light is still weak. Even to the point that I decided to buy after market leds to replace them. The 2016 had a complete redesign of the headlights and I wonder why. As for the infotament system. It is weak to say it nicely. The fact that my 2014 model can not get the same features that they introduced in the 2015 (speech to text) and 2016 (car play) is appalling. Especially when they say the hardware is not there for the text to speech but there are 3rd vendors who can give it on the 2014 models. As for the rust proofing on this truck. It was cheaply done and the protective film is wearing off. I would take it to the dealership but I decided this spring I will have it professionally fixed with some rust proof paint and not the cheap wax that GM used.

No accident has occurred yet as a result of the following deficiency. Headlights on my 2014 GMC Sierra 1500 slt are totally inadequate on high or low beam. The lighting distance is inadequate and is so directional that there is no side flair lighting for turning like you have with conventional headlights. This is a serious safety issue and needs to be addressed immediately by the NHTSA. I have had this vehicle for 1 1/2 years and the problem is ongoing since I bought it. The dealer has no solution.

Vehicle has shudder, wobble and vibration when being driven at speeds 40-80. GMC has diagnosed as a tire issue but vehicle has been seen 14+ times and tires have all been road force balanced, numerous times. GMC refuses to diagnose further and has not identified the cause of the problem. Vibration has affected other components. Commonly reported problem affecting 2014 GMC Sierra trucks based on internet search.

The backseat headrests do not remain in the upright position. They slide down with the slightest contact from the person's head. The maintenance/service person at the dealership indicated that there has been numerous complaints from owners. He indicated that at this time it is a "no fix" problem. This is unacceptable and does not meet the national highway traffic boards regulations on headrest equipment. This is a real safety concern. The service department indicated that a latch needs to be installed to hold the headrest in place. If this is not corrected, people will at some point in time sustain serious injury. I feel like contacting 60 minutes with the problem and your response.

Truck vibrated new with 8 miles when we first drove it home. Pinpointed specific speeds and returned 9+ times to dealership over 7 months. Tires (twice), shocks and rear end were all replaced but did not stop vibration. 5 months from purchase we were followed by a neighbor and they saw my truck "dog tracking" (traveling sideways down the road). Dealer noted but would not follow at distance and speed required to witness the "dog tracking". dealer told me they were clueless and come get the truck. Local auto repair shop followed me and said there is definitely a problem. Front center of wheel to back center of wheel measures 1/2 inch less on driver side than passenger side but dealer says that is not a good measurement because their computer says everything is fine. This truck vibrates and "dog tracks" and dealership refuses to make proper offer and has given up on repair attempts. I am presently seeking help from a different dealer.
