STEERING:ELECTRIC POWER ASSIST SYSTEM

17V241000 · April 11, 2017

The defect
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2016 GLE300d 4Matic, E400 4Matic Coupe, GL63 AMG, GLE350, GLE350 4Matic, GLE350d 4Matic, GLE400 4Matic, GLE43 AMG Coupe 4Matic, GLE550e 4Matic, GLE63 AMG 4Matic, GLE63S AMG 4Matic and GLE63S AMG Coupe 4Matic vehicles, 2017 E300 4Matic and GLS63 AMG 4Matic vehicles, and 2016-2017 GL350 4Matic BlueTec, GL450 4Matic, and GL550 4Matic vehicles. The affected vehicles have an electric power steering connector that may be insufficiently sealed, allowing water to enter the control unit.
The risk
If water enters the power steering control unit, the power steering assist may be deactivated, increasing the risk of a crash.
The remedy
MBUSA will notify owners, and dealers will replace the connector and inspect the electric power steering rack, replacing the rack as necessary. These repairs will be performed free of charge. Remedy parts are currently unavailable. Interim notices informing owners of the safety risk are expected to be mailed June 30, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact MBUSA customer service at 1-800-367-6372.

STEERING:ELECTRIC POWER ASSIST SYSTEM

16V899000 · December 14, 2016

The defect
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 SL550, 2013-2014 SL63 AMG, 2014-2016 E350, 2014 E350 Cabriolet, E350 Coupe, 2014-2015 S550, 2015 E350 Bluetec, 2015-2016 E400, 2016 E550 Coupe, and Maybach S600 vehicles manufactured August 23, 2012, to August 14, 2015. The affected vehicles use an electric power steering system that may have improperly soldered contacts inside the control unit, potentially resulting in the power steering system deactivating while driving.
The risk
If the control unit pins lose connection, there would be a loss of electric power steering assist, increasing the risk of a crash. The increase in pin contact resistance can also increase the risk of a fire, even while the vehicle is parked and ignition is off.
The remedy
MBUSA will notify owners, and dealers will replace the electric power steering control unit, free of charge. The recall began October 13, 2017. Owners may contact MBUSA customer service at 1-800-367-6372.

ENGINE AND ENGINE COOLING:ENGINE

15V505000 · August 11, 2015

The defect
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 Mercedes Benz E350, E400, E400 4Matic, E63 4M S AMG, E350 4Matic, E63-4M S AMG, 2015 CLS400, CLS400 4Matic, CLS550, CLS63-4M "P" AMG, and CLS550 4Matic vehicles manufactured April 16, 2015, to April 22, 2015. The integral steel cable that secures the rubber seal to the bulkhead might have been damaged due to the supplier rework of the rubber seal. In the event the rubber seal is not properly secured around the engine compartment, it is possible for the rubber seal to temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed.
The risk
If the rubber seal falls into the engine compartment, it may contact parts of the engine or exhaust system, increasing the risk of a fire.
The remedy
MBUSA will notify owners, and dealers will replace the rubber seal, in the engine compartment, free of charge. The recall began on September 2, 2015. MBUSA's number is 2015080001. Owners may contact MBUSA customer service at 1-201-573-5339.

An investigation means NHTSA has decided a pattern is worth examining. A preliminary evaluation is often closed with no action; an engineering analysis is the stage that usually precedes a recall.

Desiccated Air Bag Inflator Rupture

EA21002

Still open engineering analysis · opened September 17, 2021

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.
