2015 Chevrolet Silverado 2500

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.

LT265/60R20 121S E Yokohama Geolander AT4, manufacturer date of 2924. While driving south on Interstate 95, the driver’s side rear tire sidewall blew out, inside sidewall. The tires have approximately 14000 miles on them. There were no sidewall defects noticed approximately 4000 miles prior during a tire rotation. Nothing was hit in the roadway and proper pressure is maintained in all tires. There was no indication, tpms warning, that the tire was losing pressure prior to the blow out. There does not appear to be any damage to the tread area of the tire. Control of the vehicle was maintained to a stop in the breakdown lane. There were no injuries.

What component or system failed or malfunctioned, and is it available for inspection upon request? Truck caught fire in driveway about 5 minutes after parking truck and turning off engine. Truck is still in spot it burned and available for inspection. How was your safety or the safety of others put at risk? If I had been in truck when it caught fire, I could have burned. Has the problem been reproduced or confirmed by a dealer or independent service center? NA Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No

The contact owns a 2015 Chevrolet Silverado 2500. The contact stated that while driving approximately 65 MPH with the rear defroster activated, there was an electrical burning odor inside the cabin of the vehicle before the rear window cracked and then shattered. The cause of the failure was not yet determined. The local dealer and the manufacturer were notified of the failure, but no assistance was provided. The contact was informed that the VIN was not included in the Extended Warranty Coverage related to the failure. The rear window was replaced by the local glass repair shop. The contact stated that the failure reoccurred while driving, and the rear window shattered while a grandson was seated in the rear seat. During the failure, there was no injury sustained. The cause of the failure was not yet determined. The failure mileage was approximately 85,000.

The contact owns a 2015 Chevrolet Silverado 2500. The contact stated that while driving approximately 50 MPH, the vehicle started to vibrate and shudder abnormally. There was no warning illuminated. The contact continued driving at approximately 30 MPH. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The contact had another 2015 Chevrolet Silverado 2500 in 2025, and the vehicle experienced similar symptoms before the transmission failed. The contact stated that the vehicle was towed to a dealer, who advised that this was a known failure with the 6-speed transmission. The contact was informed by the dealer that the torque converters were too small for the transmission. The manufacturer was not informed of the failure. The failure mileage was approximately 109,000.

My pickup truck has a Duramax diesel engine with a CP4 diesel injection pump. That pump has not failed yet in my truck. However it has been known to fail in numerous other GM vehicles with Duramax engines and when it does fail the engine comes to a complete stop and cannot be restarted. This is a potentially hazardous even fatal situation. Repair if the pump fails is very expensive - $12,000 to $14,000 in some cases. I would like GM to replace the injection pump at my dealership to ensure this known failure does not occur. My pickup truck is otherwise in excellent condition.

On 8/25/2025 I purchased a used 2015 Chevy Silverado 2500HD from a auto dealer and they had put new tires on the truck that aren't rated for a 2500 HD, I contacted them and they offered me $400 to replace them with the correct tires that cost me $1319.78 they refuse to help me anymore which is putting my life and others at stake if a tire is to blow out hauling heavy loads that the tires aren't rated for. That 3/4 ton truck is suppose to have tires with a (E) rating, also the TPMS system does't work because all the tires are under inflated for that truck. They have been contacted about this issue; FMVSS No. 120: FMVSS No. 139: FMVSS No. 138 cover this issue! The dealership violated the NHTSA standards and consumer protection laws among other laws.
