GM refuses to repair the defective finish on my truck, their claim is that it only applies to trucks covered under the 3 year -36k warranty. This is a manufacturing defect that they admit to in the attached TSB. There should be a recall mandated for this. We spent a ton of hard earned money on these trucks.

Defect investigations
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. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

What 2014 GMC Sierra 2500 owners say
Most recent owner complaints, unedited.
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.
Backing out of driveway, suddenly lost the transmission. I was stranded at about a 45-degree angle into the traffic lane. I had no gear position indication (an automatic) and couldn't move the truck under it's own power. Shut it off and restarted twice before I got it into "limp-mode" and, while abrupt and harsh, managed to get back into my driveway. Found fault code U0101, Lost Communication with TCM (Transmission Control Module). Had never heard that this has become a common problem. Discovered quickly GM has no parts available, no repairs available, and that it is happening to thousands of GM trucks from model years 2008 to 2015. The truck is useless without this module function. We use this truck to tow a 12000+ lb. travel trailer. I can't imagine how bad this could have been in freeway traffic with such a load. Have been told GM put the part on a national back order in October of 2022, with no estimate of availability. It's now late August of 2023 and still nothing available. Has me concerned that one of these vehicles could stall right in front of me in traffic! I can't afford to replace this vehicle, can't move it, and am relegated to going to work on a motorcycle- in traffic with other GM trucks just waiting to experience this failure. And winter is coming...
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.
2014 Sierra 2500HD SN ([XXX]) 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. All the while, vehicles passing in danger of head on collision because there was only one officer directing both sides of traffic. GM is aware of this issue that cost me $10336 at GM Dealership where repaired. Had I been aware, I would have had this replaced this Bosch CP4 part to prevent the unsafe conditions I encountered. One message came on dash, restricted power, and I was powerless. Final Bill stated “Found Injection pump has come apart internally and has put metal through the system.” Internet search stated: According to InjectorsDirect.com, the 2011-2016 Duramax suffers from a high pressure fuel pump issue unique to this year-range model. Failure of this CP4 pump is usually catastrophic, causing metal particulates to contaminate the entire fuel system. Please help this from happening to another person. These trucks are advertised showing families pulling campers traveling through mountains. That is exactly what my family was doing. I have additional documentation if needed. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
The vehicle experienced a catastrophic failure of the fuel pump while towing a horse trailer on a busy state highway. This was a major safety risk because the vehicle gave no warning before it just stop working. It was a miracle we were able to coast off the highway into a wide spot that was able to accommodate both the truck and the horse trailer. The truck only has 77,000 miles and we are being told that none of the repair is covered under warranty. We were also told that the fuel pump has completely contaminated the entire fuel systems, including the injectors so everything must be replaced. The quote we received from the dealership for this massive repair is $12,208.59. No warning lamps, messages or other symptoms occurred until the truck died. Once the truck died, it could not be restarted and then began displaying a code that said the fuel filter needed to be replaced.
The gear shift went loose when I stopped and went to put it in park. Then no ability to shift or re-start the truck. The cable broke and I was told this is a known issue. My report says that there are no un-repaired recalls on this truck. Why is there no recall on this known issue?
I own a 2014 gmc sierra 2500hd. It is in very good condition and well maintained with less than 140,000 on it. One day after work I got into my truck and as soon as I started it I heard my dash crack. It cracked just to the right of the instrument panel by the dash vent and windshield. And has been growing ever since. If the dash is this brittle in a truck that is only 6 years old and been very well taken care of it is a safety issue. If I were to get into a crash and my airbags were to deploy, shards of hard brittle plastic would be sent through the cab possibly causing more injuries.
Dashboard cracked adjacent to passenger airbag potential safety issue since there is brittle plastic in the area where airbag deployment would take place. This issue has been reported before by me and many others and yet no action has been taken by the federal safety agency or gm for a remedy. I'm skeptical about whether it's worth taking the time to make such reports to the federal safety agency when your response sounds more like it was written by gm corporate communications rather than the public safety advocate you are supposed to be. You claim there is insufficient data to take action. Model years affected are from 2007 through 2014 on numerous gm nameplates ie: avalanche, silverado, tahoe, suburban, yukon (xl), sierra and escalade. Erring on the side of safety should, at least, prompt an investigation from the data already received. It should also be considered that this design and its implementation occurred when gm was being bailed out by tax payers and quite a few of them are now left holding the bag while they are potentially at risk..
The rear sliding window stopped working after I tried to open it using the switch located near the rearview mirror. It had only been opened less than 12 times.
