COMMUNICATION · Campaign 19V787000 · Nov 4, 2019
Defect: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2013-2017 vehicles due to a software fault that may cause the date and time for the emergency call system (eCall) to differ from the actual date and time, potentially relaying an inaccurate vehicle location. For a full list of the affected models visit: https://static.nhtsa.gov/odi/rcl/2019/RMISC-19V787-4620.pdf
Consequence: An inaccurate vehicle location may delay emergency responders, increasing the risk of injury.
Remedy: MBUSA has initiated an Over the Air (OTA) remote update. 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.

ENGINE AND ENGINE COOLING:ENGINE · Campaign 15V505000 · Aug 11, 2015
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.
Consequence: 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.
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.
