The 2020 Mercedes-Benz AMG CLA35 has 7 recalls, the most serious involving rear brake calipers with loose housing fasteners that can reduce braking ability or cause brake components to detach from the vehicle and become road hazards.
Two separate recalls affect the rear brakes more broadly: certain vehicles were not equipped with the proper gauge to check rear brake pad wear, and the owner's manual may also lack instructions for using one, meaning worn pads can go undetected. On the visibility side, a software issue in the MBUX multimedia system can cause the backup camera display to go black or fail to show a rearview image when reversing. The instrument cluster on some vehicles may also lose illumination for interior switches, making controls harder to locate while driving. Two related recalls cover the emergency call system, which can either fail to connect to emergency services at all or transmit an incorrect location after a crash, delaying response.
