The 2019 Mercedes-Benz GLC 350 has 3 recalls, all centered on the same concern: the automatic emergency call system may fail to connect occupants with emergency services after a crash, or may send responders to the wrong location.
The eCall system is designed to automatically contact emergency services and transmit the vehicle's location when a serious collision occurs. Across these recalls, the system can fail in different ways: it may not connect to the emergency call center at all, or it may report an incorrect location, meaning first responders could be delayed or sent somewhere other than where the crash actually happened. Either failure extends the time it takes for help to arrive, which raises the risk of serious injury in a situation where rapid response matters most. Prior repair attempts did not fully resolve the issue, which is why multiple recall campaigns address the same underlying problem. The remedy involves correcting the software or hardware components that support the eCall function.
