The 2021 Mercedes-Benz AMG CLA45 has 4 recalls, with two covering the rearview camera system, which can display a black screen or fail to show any image at all when reversing.
The camera issues stem from software problems in the infotainment and display systems: in one case the screen stays black or reboots on startup, and in the other the rearview image simply does not appear, both of which leave the driver without visibility directly behind the vehicle. The remaining two recalls involve the automatic emergency call system, known as eCall. In one case the system can malfunction and send emergency responders to the wrong location after a crash; in the other, the system can stop functioning entirely, preventing occupants from reaching emergency services at all. Both eCall issues mean that after a serious collision, help may be delayed or misdirected at a moment when response time matters most.
