2013 Chevrolet Silverado 3500

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.

The contact owns a 2013 Chevrolet Silverado 3500. The contact stated while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the independent mechanic where it was diagnosed with failed temperature sensors and a failed heating element in the diesel exhaust fluid (DEF) tank. The contact was informed that the heating element and the temperature sensors needed to be replaced. The vehicle was not repaired. In addition, the contact stated that an unknown repair was performed four years ago on the diesel exhaust fluid (DEF) tank. The manufacturer was made aware of the failure but did not assist. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 39,639.

The truck started shifting hard. Had it towed home. Then towed to dealership. They diagnosed it with a faulty TCM #24256861. Then said it could be up to 18 months for the part. This is unacceptable in our opinion. Additional expenses, time missed from work, etc.

General Motors produces several years of vehicles with a faulty transmission control module (TCM). From 2008 thru 2015, Chevrolet and GMC 2,500 & 3,500 trucks with the 6.6 L Duramax engine and Allison 1,000 transmission all used the same TCM; part number 24256861. This part has experienced a very high failure rate. During the summer of 2022, the stock of replacement parts was exhausted and GM seems to be postponing the manufacture or new parts. An estimated 5,000 vehicles are currently unusable due to the failure of this part and no new parts available.

The contact owns a 2013 Chevrolet Silverado 3500. The contact stated while driving 50 MPH, the vehicle lost motive power. There was no warning light illuminated. The contact was able to pull to the side of the road and restarted the vehicle. The check engine warning light illuminated but the vehicle started operating normally. The contact was able to drive the vehicle back to the residence. An independent mechanic diagnosed the vehicle and stated that the engine control module (ECM) needed to be replaced. The vehicle was not repaired. The dealer was contacted and stated that the ECM was not available. The manufacturer was contacted but no assistance was provided. The failure mileage was 56,000.

Tcm module faild on freeway when doing 60mph the vehicle suddenly down shifted causing car behind me to skid there brakes to avoid a rear end collision.Yes vehicle can be inspected for failure of transmission control module.The vehicle was diagnosed of a faulty transmission control module.. The truck has been down since December 2022.the dealer says the part had been discontinued With no release date.

I took my Chevrolet Silverado in for the airbag recall, and when it was returned to me the passenger airbag sensor was set off on the dash. The recall work wad done at Capital Chevrolet, at 6200 S I-35 Frontage Rd, Austin, TX 78745. I asked them to fix the airbag sensor problem, and they looked at it and wanted to charge me to fix it. They said that "well it's a 2013 so it probably just went bad". I find it overly suspicious that it went bad IMMEDIATELY after conducting an airbag recall. They offered to repair the airbag issue, but only if I paid them the normal rate. How in the world does it it make sense for me to pay for a recall issue. There were NO issues with the airbags before I brought it in for the recall.

This Preliminary Information communication provides information to the technician that some owners of Heavy Duty Trucks and Utilities may ask if they can lower their tire pressures. Tire pressures being set to the "Tire and Loading Label" will ensure the safe handling and ride characteristics of the truck and should not be lowered.
