the air bags

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 BIGGEST PROBLEM (OUT OF MANY) THAT MAKES THIS VEHICLE UNSAFE, STRESSFUL, AND DISCOMFORTING TO DRIVE IS HOW IT WILL RANDOMLY DECIDES TO RAISE THE IDLE TO 900+ RPM (IN GEAR) AND BASICALLY DRIVES IT'S SELF. DURING THIS CONDITION IT IS VERY DIFFICULT TO OPERATE VEHICLE. BECAUSE OF ITS RANDOM PATTERN IT CAUSED ME TO HAVE AN ACCIDENT THAT RESULTED IN $3500 IN BODY DAMAGE TO THE TRUCK. THANK GOD NO ONE WAS HURT. WEAR AND TEAR IS DRASTICALLY INCREASED AS THE VEHICLE IS TRYING TO DRIVE ON ITS OWN AS I'M TRYING TO STOP AT TRAFFIC LIGHT, STOP SIGNS, OR SIMPLY PARKING. DRIVE-TRAIN IS BANGING, BRAKES ARE WORKING HARDER, AND FUEL IS BEING WASTED. NOW, ADD A PAYLOAD OR TRAILER AS I OFTEN DO AND …

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.

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 …

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, …

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 …
