Defect

Consequence

An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.

MBUSA will also notify owners, and dealers will check software for a successful OTA or update the communication module software as needed, free of charge. The recall began December 23, 2019.

Defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2012-2014 ML350 Bluetec 4Matic and ML550 4Matic, 2012-2015 ML63 AMG 4Matic and ML350 4Matic, 2013-2016 GL350 Bluetec 4Matic, GL550 4Matic and GL63 AMG 4Matic, 2017 GLS350d 4Matic, GLS450 4Matic, GLS550 4Matic and GLS63 AMG 4Matic, 2015 ML400 4Matic, 2016 GLE400 4Matic, GLE350 4Matic, GLE63 AMG 4Matic, GLE63S AMG 4Matic, GLE450 4Matic Coupe and GLE63S AMG 4Matic Coupe, 2015-2016 GL450 4Matic and 2013-2014 GL450 4Matic vehicles equipped with the Active Curve System (ACS). In certain driving conditions, if the oil level in the ACS reservoir is below the minimum level, the oil may foam and leak out of the vent holes in the reservoir cap.

Consequence

The leaking oil in the presence of an ignition source can increase the risk of a fire.

Remedy

MBUSA will notify owners, and dealers will correct the oil level as necessary and replace the reservoir sealing cap to prevent oil foam from leaking out, free of charge. The recall began August 30, 2018. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2018070015.

14V158000Child SeatMarch 31, 2014 · 69 units

Defect

Mercedes Benz USA, LLC (Mercedes) is recalling certain model year 2014 GL350 BlueTEC 4Matic, GL450 4Matic, GL550 4Matic, and GL63 AMG vehicles manufactured November 4, 2013, through November 15, 2013. In the affected vehicles, the foldable second row seat bottom may not fold down low enough to allow proper use of the child seat achors. As such, these vehicles do not conform to Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems."

Consequence

Without the use of the lower anchor points, a child restraint may be insufficiently or improperly anchored to the seat, increasing the risk of injury to the child in the event of a crash.

Remedy

Mercedes will notify owners, and dealers will inspect and, if necessary, replace the seat pan of the second row seat, free of charge. The recall began on May 2, 2014. Owners may contact Mercedes at 1-800-367-6372.
