Defect investigations

Desiccated Air Bag Inflator RuptureOpened September 17, 2021, still open

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.

I purchased a 2012 Chevy Sonic with 65k miles on it from Carvibe LLC earlier this month. When I took it into Firestone for a full inspection, they found that the car has severe rusting to the mechanical parts along with the body of the vehicle - the entire structure of the vehicle is compromised. Someone spray painted the rust black but Firestone was still able to see the covered up rust. Firestone has deemed the vehicle unsafe to drive.

I purchased this car 2 years ago and it has caused me absolutely nothing but trouble. We have replaced the fan 4 times (twice due to the resistor thats part of the fan failed), headgasket job, intercooler punctures (once inward, once outward), failed valve cover, intake maniford, turbo seals twice, failing check values, new relays for the fan (twice), another drive belt, and now I go outside and theres a puddle of coolant under my car. I have sunk over $8,000 into this car and it has been the worst financial decision ever. Why do the parts keep failing? Why isnt there a heat gage in the dang car so I know its too hot before the light comes on?

While driving on the highway late at night, at approximately 60 mph my 2012 Sonic began to lose power and slowed to a dangerously low speed when there was nowhere for me to pull over! I literally had to coast to a spot that I could barely squeeze off the road! Then would not shift into any workable gear but 1st and after that just revved up loudly. Long story short…had to be towed 35 miles home. Then towed to a reputable garage where they concluded the transmission was shot at about 90,000 miles. Would be around $3800. to rebuild. Come to find out these cars are known for this problem! And yet somehow I’m being told by GM that it’s not included in the Turbine Shaft Fracture Recall for that car’s year/make/model!! WHY?! Needless to say….the car will be junked!
