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.

Consequence: If brake pads are constantly applied over long periods of driving, the brake components may heat up, affecting braking performance and increasing the risk of a crash. Additionally, the dragging brakes may overheat, increasing the risk of a fire.
