2011 Mercedes-Benz GL350

The defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2009-2010 ML320 BlueTec 4Matic, GL320 BlueTec 4Matic and R320 CDI 4Matic, 2011 E350 Cabriolet and E550 Cabriolet, 2009-2011 ML350, ML350 4Matic, ML550 4Matic, ML63 AMG, and C63 AMG, 2010-2011 ML450 4Matic Hybrid, E350 Coupe, E350 4Matic, E550 Coupe, E550 4Matic, and E63 AMG, 2011-2012 GL350 BlueTec 4Matic and R350 BlueTec 4Matic, 2009-2012 GL450 4Matic, GL550 4Matic and R350 4Matic, 2007-2008 SLK280, SLK350, and SLK55 AMG, 2011-2014 SLS AMG Coupe, 2012 SLS AMG Cabriolet, 2013-2014 SLS AMG GT and SLS AMG GT Cabriolet, 2005 C230 Kompressor and C320, 2006-2007 C230, 2006-2011 C350, 2008-2011 C300 and C300 4Matic, 2010-2012 GLK350 and GLK350 4Matic and 2007-2008 Chrysler Crossfire vehicles. Upon deployment of the driver's frontal air bag, excessive internal pressure may cause the inflator to rupture.

The risk

In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator could rupture with metal fragments striking the driver or other occupants resulting in serious injury or death.

The remedy

MBUSA will their notify owners, and Fiat Chrysler will notify the affected Chrysler owners. Dealers for the respective brands will replace the driver's frontal air bag module, free of charge. This recall began November 2016. Mercedes-Benz owners may contact MBUSA customer service at 1-800-367-6372 and Chrysler owners may contact Fiat Chrysler customer service at 1-800-853-1403.

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 2011 Mercedes-Benz GL350. The contact stated that the dealer had previously serviced the vehicle under an unknown diesel emission recall; however, the failure occurred after the recall repair was performed with the check engine warning light illuminated. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power with the check engine and ABS warning lights illuminated. The vehicle was towed to the dealer, and the ignition switch was replaced; however, the failure recurred. The dealer determined that the engine compartment fuse box needed to be replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was made …

- The hard brake lines from the going to the rear axle ruptured during light braking. The corroded sections have been removed and are available. - I had no indication of a problem until I went to stop the vehicle. I was able to slow the vehicle down but could not keep it from moving forward with out being in neutral. Had there been another car in front of me or in traffic, I would not of been able to stop. - The problem cannot be reproduced by a dealer, since the corroded and ruptured section of the lines had to be replaced. There has been no inspection of the issue since no accident occurred. - No warning lamps or any indication of a problem until the brake pedal was applied. Pedal was …

Malfunction with the air suspension. The vehicle is currently lowered and will not rise which is causing the tires to sit in a bent position and a horrible ride. The tires appear that they will detach from vehicle which is a safety risk for myself and others. After repairs from someone who presented themselves as a certified Mercedes’ mechanic, the issues still exist. The problems first existed about a year and a half ago, about 6 months after purchasing. I am making payments on a vehicle I am unable to safely drive or use for travel with my family. This should be a recall due to several vehicles jus in my area with same issues.

The contact owns a 2011 Mercedes-Benz GL350. The contact stated while driving 20 MPH, the brake pedal was depressed but failed to respond and went all the way to the floorboard. The contact then pumped the brake pedal until the vehicle responded. However, there was 20-foot stopping distance delay. The warning message "Brake Fluid Low" was displayed. The contact veered to the side of the road. The contact then noticed a trail of brake fluid on the ground. The contact was able to refill the brake fluid reservoir. The vehicle was taken to an independent mechanic where the brake fit knots, the brake fitting union, and brake fluid line were repaired. The dealer was not notified of the failure. …
