• Recall 2019632 [Canada]: Airbag
  Issue: on certain vehicles, the occupant classification system (ocs) may not work properly. In some cases, this could cause the airbag system to turn off the passenger-front airbag, even if an adult is seated in the front passenger seat. Alternatively, the airbag may not be turned off when a child seat is installed in the front passenger seat. Safety risk: an airbag that deploys in front of a child seat, or an airbag that doesn't properly deploy in front of a passenger could increase the risk of injury in a crash. Corrective actions: mercedes-benz will notify owners by mail and instruct you to take your vehicle to a dealer to replace the front passenger seat cushion.

• Recall 2017490 [Canada]: Airbag
  On certain vehicles, electrostatic discharge, when combined with a broken clock spring and insufficient grounding of the steering components, could lead to an inadvertent deployment of the driver's frontal airbag. Unintended airbag deployment, in a non-warranted (non-impact) situation, could startle the driver, which could result in a crash causing injury and/or property damage. In some instances, inadvertent deployment could cause minor injuries to vehicle occupants. Correction: dealers will add sufficient grounding to the steering components. Note: a broken clock spring would result in a driver airbag warning message appearing in the instrument cluster, as well as a red airbag warning lamp illuminating.

• Recall 2017062 [Canada]: Engine
  On certain vehicles, the starting current limiter could be overloaded under certain conditions. In the event the starter is blocked, a very high electric current could flow through the starting current limiter during repeated engine starting attempts. The high electric draw could cause the starting current limiter to overheat causing the surrounding components to melt which would increase the risk of fire causing injury and/or damage to property. Correction : dealers will install an additional fuse in the electrical line to the starter.

• Pedestrian alert sounds investigation # DP22005

  Nhtsa received a petition on or about july 18, 2022, requesting that federal motor vehicle safety standard (fmvss) 141 be applied to all electric and hybrid vehicles operating in the united states. The petition can be reviewed at nhtsa.Gov under odi number 11486072.Fmvss 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 kg or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after march 1, 2021.The petitioner asserts that hybrid and electric vehicles to which the standard does not apply should be found to contain a safety defect. In support of the petition, the petitioner includes findings contained in a bill introduced in the house of representatives in 2009, the pedestrian safety enhancement act of 2009, h.R. 734, 111th cong. (2009). A related bill, the pedestrian safety enhancement act of 2010, became law in january 2011 (pub. L. 111-373). The petitioner requests that nhtsa require all electric and hybrid vehicles comply with fmvss 141, regardless of production date.The defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.The associated product list is not exhaustive and may contain vehicles that are equipped with pedestrian alert sounds.

• 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.
