What can fail
The transmission wiring harness connection may not have been correctly wired during production or a prior recall repair, exposing the electrical connector to corrosion and potentially causing an electrical short-circuit.
The 2020 Mercedes-Benz AMG E53 has 10 recalls, the most serious being a transmission wiring harness defect that can cause an electrical short circuit and increase the risk of a vehicle fire. Prior repair attempts did not fully resolve this issue, and some vehicles may also have been affected during original production.
Two recalls address the front passenger seat, which may lack a proper range limiter, allowing it to move too close to the airbag and raising the risk of injury if the airbag deploys in a crash. There is also a concern with the 48-volt battery system, where a failure can disable safety features including hazard lights, electric seats, and automatic door locks during a crash.
Several recalls cluster around the vehicle's emergency communication system. The eCall function, which contacts emergency services after a crash, can fail to activate, transmit an inaccurate location, or send responders to the wrong address entirely. A separate recall covers the rearview camera, which can go blank due to a software error and reduce the driver's visibility when backing up.
