• Desiccated air bag inflator rupture investigation # EA21002

  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.

• Front roof panel detachment investigation # PE21001

  On january 8, 2021, after ongoing review with mercedes benz, the national highway traffic safety administration (nhtsa) office of defects investigation (odi) opened pe21-001 to assess allegations of front roof panel detachments while driving at highway speeds in certain 2015 mercedes-benz (mercedes) c-class vehicles.The subject front roof panel is a stationary panel composed of polycarbonate and is attached to the vehicle via adhesive at the time of manufacture. The panel is found on subject vehicles equipped with panoramic sunroofs. Over time, the subject panels may exhibit cosmetic degradation leading to replacement of the panel, a procedure which entails: removal of the old panel and adhesive, site preparation, and installation of a replacement panel with new adhesive.The consumer complaints that prompted the opening of pe21-001 all described detachments of front roof panels that had been replaced after the vehicle was put into service.Mercedes internal investigation identified a broader scope of affected vehicles (2014-2020 cla, gla, c, s, glc, and gle class) and found the following potential service procedure- related causes of front roof panel detachments:- improper surface pretreatments such as the use of the wrong primer or cleaner or scoring of the surface; or - use of the incorrect adhesive.These conditions lead to a front roof panel bond that, even if sound at the time of repair, cannot maintain its strength over time and environmental exposure.Mercedes updated its service and parts ordering systems to reinforce the proper use of specified kits and procedures via webinars, shop foreman meetings, and explicit reference to the risks incurred by diverging from the repair procedures. Mercedes is also furnishing parts ordering assistance, and will hold dealerships accountable for improper repairs.Odis analysis of the ten complaints it has received from the public (voqs) and mbusas complaint data submitted in response to the information request letter for pe21-001 identified a total of 57 non-duplicative reports alleging incidents in which the front roof panel detached from the vehicle while in motion. Included within the 57 reports are incidents where consumers state the panel detached "...And flew off into traffic."on march 19, 2021, mercedes notified nhtsa that it would recall subject vehicles with front roof panels known to have been replaced after the original sale of the vehicle. In total, the recall (designated as recall 21v197) covers 15,099 vehicles that were ever registered in the united states. Based on recall 21v197 and the remedy implemented by mercedes, further investigation does not appear to be warranted at this time.Accordingly, this investigation is closed.The odi complaints cited above can be viewed at www.Nhtsa.Gov under the following odi identification numbers: 11376425, 11352686, 11351629, 11349158, 11341541, 11337594, 11324100, 11311591, 11222127, 11404183

What component or system failed or malfunctioned, and is it available for inspection upon request? Car is at mercedes dealer for repair. How was your safety or the safety of others put at risk? Yes, car lost acceleration on freeway and put other drivers at risk on the road. Lucky to get off freeway and pull over without any injuries. Has the problem been reproduced or confirmed by a dealer or independent service center? Dealer provided feedback cracked piston, cylinder # 2. Reading on forums, others continue to have the same issue. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected by mercedes bens manufacturer. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? In retrospect, some slow acceleration delays 1-2 days prior, but not consistent.

While driving, the malfunction indicator lamp (mil/check engine light) came on. After some digging this was caused by an obd ii code of P052E, which indicates a blocked crankcase vent valve actuator. This appears to be a manufacturing defect in these vehicles.
