Vehicle experienced a catastrophic mechanical failure characterized by a percussive "shotgun blast" noise from the rear chassis, followed by an immediate, total loss of braking power (pedal to the floor) and a violent loss of directional stability. This incident represents an aggravated safety failure of known GMT900 platform defects. The technical chain of causality began with the factory exhaust manifold fasteners suffering a metallurgical shear, a universal defect documented under GM Bulletins 19-NA-218, PIP5075, and PIP4701. This shear created a high-velocity, high-heat exhaust leak directed at the brake master cylinder and vacuum assembly. This "heat soak" event compromised the engine-mounted mechanical Brake Vacuum Pump (Recall N192268490 / NHTSA 19V645) and destroyed the internal seals of the Master Cylinder (Special Coverage 15143 / NHTSA 11V599), resulting in total depletion of vacuum assist and hydraulic pressure. Simultaneously, the "shotgun blast" and violent swerve were caused by structural failure consistent with Rear Brake Caliper Bolt Fracture (GM 13247 / NHTSA 13V342) and Rear Axle Shaft/Pin Fracture (GM 14892 / NHTSA 14V819). This mechanical collapse caused the caliper to strike the wheel, resulting in a catastrophic rim blowout and immediate loss of tire pressure. Despite the vehicle having aftermarket long-tube headers installed, the root cause of the heat-related brake failure was the failure of the OEM GM manifold fasteners which snapped off in the cylinder head, as documented in the aforementioned bulletins. Under the Magnuson-Moss Warranty Act, the manufacturer remains liable for these pre-existing safety-critical defects. The vehicle is at Glenn Polk Chevrolet for a 901-series Product Allegation Investigation (Case #90199492). This report is filed to demand federal oversight into these life-threatening defects. The combo of failed fasteners, rim blowout, and compromised braking created a vehicle that was both unable to be steered or stopped

My GMC which is well cared for and only has 121,000 miles has a rusted through frame (mid-vehicle, left side) which has made the truck unsafe to drive. The steel used is inferior, my neighbor across the street also has this truck, 2 years newer, and is doing the same thing. As I have researched this issue I have found out that this is a critical failure of the GMC Sierra for several model years due to a failure to protect the steel used in northern states which compromises structural integrity. When Toyota had this issue, they stepped up and replaced the frames. General Motors, please tell me what you intend to do with this. It is a 5.3 Litre with 121,000 miles on it, in other words, still a baby for such a fine engine. This is not right. I am seriously discouraged. For my family, this is devastating. I still owe $2000 on this vehicle. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is not a safety item, but one that causes undue financial hardship for the owner. It is widely know that the dash on certain 2007-2014 GM vehicles (generally trucks and SUV's) is susceptible to cracking. This causes devaluation of the vehicle if not fixed and is reported to cost between $2,000-2,500 to repair. It is my opinion that the cause of this is the use of substandard parts by GM and they should issue a recall for the repair of the dash.

My truck keeps getting code p2138, when it happens I get reduce engine power alerts, check engine light and it stalls. It's been doing it for years now. It's very unsafe, last time it it did it I was on the freeway and had to pull to the side, but the car has no acceleration so vehicles are passing me by at 75- 80mph and I almost had a very bad accident.

The main body frame is completely rusting through from under the drivers side door back past the fuel tank. It is rusting through on the passenger side as well. The large amounts of rust have caused other issues throughout the entire body of the truck as well as rusting of other components. The frame of this truck will need to be replaced as there is no way to repair it or the vehicle becomes scrap. This vehicle is available for inspection. These issues were not visible when purchased from the dealer. This issue gradually became visible after the rust and undercoating wore away that had been applied previous to our purchase from a known dealership.

On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.
- 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.

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 www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, 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 nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
