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 contact owns a 2013 Mercedes-Benz GLK350. The contact stated that while driving at an undisclosed speed, the accelerator pedal became stuck and almost caused a crash. The contact shifted the transmission into neutral(N) while the vehicle continued to accelerate and the RPM was extremely elevated. The contact was able to turn off the vehicle while the transmission was in neutral (N). The vehicle was taken to the dealer, who determined that the accelerator pedal was defective and needed to be replaced. The vehicle was not repaired. The contact discovered from a Carfax report that the accelerator pedal had previously been replaced. The manufacturer was made aware of the failure. The …

I am reporting a safety issue involving my Mercedes-Benz GLK 350 following repairs performed by an authorized dealership, Critz Mercedes-Benz in Savannah, Georgia. I brought the vehicle in due to persistent noise when shifting gears and steering-related symptoms. I asked the dealership to fully investigate the cause of the issue and not limit the diagnosis or repair to any single system, as I am not a mechanic and relied on their expertise. I paid $5,674.90 for the repair. During the process, a service advisor contacted me regarding an additional charge of approximately $800, which I approved to ensure the vehicle was repaired correctly and to avoid any claim that I declined recommended …

NHTSA complaint 11705730, quoted in part. Filed by an owner and not verified by NHTSA or by us.

I am writing to express a serious safety concern regarding the Mercedes-Benz GLK 350, particularly related to the fuel pump system under the rear passenger area. It has come to my attention that the fuel pumps in these vehicles emit a strong, unpleasant odor every time the car is refueled. This poses a significant risk to both the driver and passengers. I have personally experienced a similar issue with a 2013 Mercedes-Benz GLK350, where the pumps were constructed with a substandard plastic material that, over time, will melt and start dripping from the top of the pump. This degradation of materials significantly compromises the integrity of the system, creating a serious hazard that could, …
