The 2020 Mercedes-Benz AMG CLA45 has 6 recalls, the most serious involving spark plugs that can break apart over time, cause engine damage, and lead to a stall while driving.
Two separate recalls affect the emergency call system: in one case the system may fail to connect to an emergency services center at all, and in another it may dispatch responders to the wrong location. Both issues delay emergency response after a crash. On the visibility side, two related recalls cover the rearview camera failing to show an image when reversing, either due to a software error or the multimedia display going black or rebooting, leaving the driver without a rear view when backing up. There is also a brake-related recall: certain vehicles were not equipped with the gauge needed to check rear brake pad wear, and the owner's manual may not include instructions for using it, meaning worn pads could go undetected and reduce stopping ability.
