NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2014 GMC Sierra:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2014 GMC Sierra owners say
Lights all 64 →
I purchase this vehicle nov. 2013, and ever since I notice that the headlight on this vehicle do not light the road properly, whether you have them in low or high beam. The distance of the low and high beam appear to be the same (at times it seems the highs) are aiming skyward. Not to long ago I almost ran over a woman and a child who were crossing a street over to my left when I was attempting to make a left turn (this was a dark area). Luckily I was going slow when I was making the turn and was able to see them when the headlights hit them and came into view. By this statement I am trying to point out that there no lighting to either side of the vehicle, I am sure (positive) that if I would have been making a right turn an accident would have happen. Are there any recalls regarding this problem? If not, I think there should one. …
The vehicles headlights are dangerously ineffective. They rarely illuminate the distance between 2 telephone poles. The ineffectiveness of the headlights is amplified on hills or on any turn. The during the transition from decline to incline, you sometimes have barely a trucks length of illumination. Any corner on a dark road requires a severe decrease in travel speed to avoid over driving the lights. I have never driven a vehicle that made me feel more apprehensive to get behind the wheel after dark. I visited the dealer who executed a TSB that increased headlight voltage and replaced the bulbs. It made a negligible improvement and left the vehicle still unsafe at night. I frequently travel on rural roads with no street lights. I have almost hit wildlife too many times to count due to the poor visibility caused by these dangerous headlights. …
Transmission & drivetrain
The contact owns a 2014 GMC Sierra. The contact stated that while making a right turn into the driveway, the steering wheel had become stiff. No warning light had illuminated. The vehicle was no longer being driven since the steering wheel was too stiff and required excessive force causing control to be lost while driving. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 105,000.
My vehicle started with a vibration on or around 12,000 miles. The vibration slowly increased as time went on. I made appointment with the dealership where the vehicle was purchased.(capitaland motors) at this time the vibration was strong enough to vibrate the back window. It would start at 30mph and get worse at 45mph. The mechanic checked balance and road force the tires. But told me that the vibration was normal and he could fix my back window. I called GMC and filed a complaint. They told me to take it to another dealership. I did on 11/25/14. This time I took it to goldstein Buick-GMC. They could feel the vibration in the steering wheel and seat. They check tires again. They felt it was the tires and wanted me to buy new ones. Told me the tires were not under warranty. That day I called Goodyear and found out my tires were under warranty, they would be prorated. …
Body & structure
While detailing my truck on October 30, 2017 I discovered a crack on the dash about an inch and a half long running from the top left of the airbag cover towards the defroster vent . Took the vehicle in for servicing on October 31, 2017 and they stated to contact GMC cares that they were familiar with this kind of problem. I called GMC they stated they were unaware of this problem on my make and model truck. They stated that I needed to contact the dealer and have the dealer contact GMC. The dealer told me to contact GMC. After doing a quick search on the internet I discovered this has been an ongoing problem that GMC has been aware of and is not fixing and apparently this will only going to get worse as time goes by. …
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.
