These two recalls describe the same underlying defect and should be treated as one issue.
The 2019 Mercedes-Benz GLS 550 has 2 recalls, both tied to the automatic emergency call system that can fail to connect occupants with emergency services after a crash or send responders to the wrong location.
When the eCall system malfunctions, it may either transmit an incorrect GPS location or fail to place a call entirely, meaning emergency responders could be delayed or directed elsewhere following a collision.
