general problems of the 2014 GMC Sierra

Braking system failure at low speeds.

Ac condenser system failure, leaks; many gm owners are reporting this same exact issue.

My truck is shaking at speeds 65+mph. I recently had my front end alligned and tires rebalanced still the same shaking is occuring. It is to the point that it is uncomfortable to drive and dangerous.

The factory supplied running boards have treads that fail to provide any traction for feet while entering or exiting. The treads need to be rotated 90 degrees and made of a softer rubber with a deeper and more aggressive tread pattern. As they exist they are very slippery especially when wet or frozen. Given the added height of trucks it requires some use of the running boards to enter/exit the truck. Especially when you are 68. As designed and manufactured they are actually an accelerant in slipping feet. I feel they are of defective design and manufacture and could/should be made safer. I fell three times in the past months while exiting my Sierra 1500.

The center console with shake excessively if going 70-80 mph. It will also shake bad going down a main road I drive on daily doing 45-55 mph. The truck has had the tires rebalanced twice now with no solution found. The truck has been in the shop over 20 days all together for other vibration issues as well.

On 12/12/14, my husband came home at approximately 2:00 pm and approximately an hour the garage was on fire and fire appears to have started in the truck. Gm came out and investigated with usaa but since there is nothing left of the truck the cause is undetermined. The entire house is a total loss. There is no roof left to truck. Gm trying to blame on a refridgerator cord or cord in workshop or sprinkling system.

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. My son broke his nose and I am suffering from a broken nose, concussion and a bursted vertebrae. Neither airbags deployed which could've made a huge difference on our injuries.

The lights on this vehicle are unsafe in that they only project for a short distance and don't allow any light to the sides on corners or on upslopes of highway dips.

I purchased new in 2014 a GMC Sierra 4x4 I take very good care of my vehicles I park inside a heated garage an wash once sometimes twice a week, including undercarriage. In January while washing undercarriage I noticed the coating on the frame is completely coming off the frame with just the spray of garden hose. I notified the service department at upstate Chevrolet in attica at my last service March 16 2015. The dealership will also verify how well I maintain my vehicles. I am now waiting for a response! in the mean time I went on line to see if anyone else is having same problem and to no surprise alot of GMC truck owners are complaining of this existing problem as well. Please contact me. My family an I have been dedicated gm owners and I am asking if this falls under the lemon law. Thank you for your concern.

Headlights are a safety issue with this truck. Can not see the sides of the road and the roadway is very dim. I have contacted gm many times with no answer to the problem. One time they said, turn on the fog lights when you are about to turn a corner.

When we took our new truck for a test drive we noticed a vibration. The dealership supposedly checked it out and took care of it. When took delivery of the truck and drove it home the vibration was better at a slower speed but increased as the speed increased. We returned the truck to the dealership and they checked it out and said that they balanced the tires and rotated the driveshaft 180 degrees. It seem to be a little better. Because we take this truck to florida for the winter and it is loaded my husband decided that he would put some weight in the back of it to see how it would affect it. The vibration was better at a slower speed and worse at a high speed on the highway. The truck has now been back at the dealership for a week and we have not heard anything in regards to it. They are supposed to be doing an electronic vibration analysis on it. My husband has researched this problem on the internet and there seems to be a lot of complaints about this problem. Hopefully people are registering them on your website.
