Known issues on the 2020 AMG GT C. The 2020 AMG GT C has two recalls on the federal record, each tied to emergency calling. Certain cars carry communication module software that may pass the wrong vehicle location to the emergency call center in a crash. Separately, a fault in the module's SIM card software on certain vehicles can break the mobile connection so that an emergency call cannot be placed at all. Dealer or over-the-air software updates address both. This manual gives wiring diagrams, diagnostics, procedures, specifications and torque values for the module and its connected circuits.
