NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2014 GMC Sierra 2500:
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 2500 owners say
Steering
2014 Sierra 2500HD SN ([redacted]) Leaving on vacation towing camper with family Bosch CP4 fuel pump issue left me stranded on a HWY 9 just outside Clinton, AR which is a 2 lane HWY with no shoulder. The vehicle gave me no prior warning, dash board suddenly read power restricted followed immediately with complete power loss as I reached to top of hill. I was forced to steer and brake the truck and camper with no power, down the hill to prevent vehicles from passing at crest of hill. This left me and my family and numerous other drivers in a very dangerous situation as cars tried to pass. I had to open the hood and try to determine what was going on. I directed traffic until a Van Buren County, AR Sherriff's Deputy arrived scolding me to get the truck and trailer out of the highway. I was forced to unhook trailer in middle of HWY and leave it. …
We have problems starting the truck . You cant just turn the key it takes you wiggling it and pulling it out of the ignition some times flipping your key just a pain in the neck. Had it checked a year ago and they said it was the way we were sticking the key in and it wore down the key. So they made us a new key. It worked for a week or so and went right back to doing the same thing. So now we just dealt with it . Till now .... Now it takes about 3 to 5 mins to get the key to turn and is out of warranty and I really think it was an ignition problem not a key problem. The truck only has 55,000 miles on it. Im so frustrated with my new truck. I have a 04 suburban 223000 miles on it and still have no problems with turning the key.
Air bags
2014 GMC Sierra 2500HD. My dash has started to crack around the passenger airbag and driverside gauge cluster. Dash material is brittle and serves as a hazard should the airbags deploy during an accident.
Dashboard under front windshield prone to cracking. Initially this would sound like it is only a cosmetic issue. The problem is that typically the first crack occurs at the front/left corner of the front passenger airbag panel. As the vehicle ages under temperature fluctuation and uv exposure the initial crack widens and more develop. Also, from pictures taken of a 2007 GMC yukon and 2007 Chevrolet avalanche the airbag compartment cover appear to be shifting and lifting as the cracking continues. The degraded plastic surrounding the airbag cover could be a shrapnel hazard to vehicle occupants in such close proximity to an explosive airbag deployment. This could also diminish the effectiveness of the airbag if it is punctured. …
Engine & cooling
The contact owns a 2014 GMC Sierra 2500. The contact stated that the vehicle failed to start as needed. The contact stated performed a diagnostic test on the vehicle and determined that the engine control module (ECM) needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were both contacted and informed the contact that the vehicle was out of warranty. The failure mileage was 74,319.
The biggest problem (out of many) that makes this vehicle unsafe, stressful, and discomforting to drive is how it will randomly decides to raise the idle to 900+ RPM (in gear) and basically drives it's self. During this condition it is very difficult to operate vehicle. Because of its random pattern it caused me to have an accident that resulted in $3500 in body damage to the truck. Thank god no one was hurt. Wear and tear is drastically increased as the vehicle is trying to drive on its own as I'm trying to stop at traffic light, stop signs, or simply parking. Drive-train is banging, brakes are working harder, and fuel is being wasted. Now, add a payload or trailer as I often do and problems are magnified. Essentially the vehicle is aging and wearing its self out before its time. I have been ordered by pima county court to have the vehicle fixed or replace. …
