On June 18, 2021, an additional 9 vehicles were added, including certain 2021 GLA250, GLC300, 2018 S450, E400, and 2017 CLA250 vehicles. The communication module might have been inadvertently deactivated during a service visit, which could have disabled the Emergency Call (eCall) function.

Risk

A disabled eCall system would prevent a vehicle occupant from contacting emergency services through the call center in an emergency, potentially delaying emergency responders and increasing the risk of injury.

Remedy

MBUSA will notify owners, and dealers will inspect the communication module and activate it, if necessary, free of charge. The recall began March 31, 2021. Letters for the owners of the 9 additional vehicles were mailed July 9, 2021. Owners may contact MBUSA customer service at 1‑800‑367‑6372. MBUSA's number for this recall is 2021030005.

Recall number 21V072000 · Recall details

What is wrong

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2016 - 2021 CLA-Class, GLA-Class, GLE-Class, GLS-Class, SLC-Class, A-Class, GT-Class, C-Class, E-Class, S-Class, CLS-Class, SL-Class, B-Class, GLB-Class, GLC-Class, and G-Class vehicles.

Risk

Failure of the eCall system may result in emergency responders being dispatched to the wrong location, increasing the risk of injury following a crash.

Remedy

MBUSA will notify owners, and the communication module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. The recall began March 12, 2021. Owners may contact MBUSA customer service at 1‑877‑762‑8267. MBUSA's number for this recall is 2021020025.

Recall number 21V058000 · Recall details

What is wrong

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2019 C300, C300 Coupe, CLS450, E450 Coupe and S450, 2017-2019 E300, 2018 E400 Coupe, E400 Stationwagon, and 2018-2019 S560 vehicles that have previously had the instrument cluster replaced. The software in the replaced instrument cluster may cause the seat belt warning system to not operate properly, only displaying a solid warning light if either the driver or passenger seat belt is unfastened, instead of a blinking light with an audible tone.

Risk

Without the audible tone and blinking warning light to remind the front seat occupants that their seat belts are not buckled, they may forget to buckle their seat belt, increasing their risk of injury in the event of a crash.

Remedy

MBUSA will notify owners, and dealers will update the instrument cluster software, free of charge. The recall began September 8, 2020. Owners may contact MBUSA customer service at 1‑800‑367‑6372. MBUSA's number for this recall is 2020080015.

Recall number 20V449000 · Recall details

What is wrong

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2017 Mercedes-Benz E300 4Matic, E300, E43 AMG, and E400 vehicles.

Recall number 16V758000 · Recall details

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.
