The 2021 Mercedes-Benz AMG GLC63 has 6 recalls, the most serious involving a fuel pump that can shut down without warning, cutting drive power and raising the risk of a crash.
The seatbelt pretensioners may not perform correctly in a crash, meaning the belts may fail to restrain occupants properly when it matters most. On the visibility side, headlight electrical connections may not be sealed against water, causing the headlights to fail and reducing what the driver can see ahead. The backup camera can also fail, either showing a black screen or rebooting when the vehicle is shifted into reverse, leaving the driver without a rear view while backing up. Two recalls address the automatic emergency call system: in one case the system may be disabled entirely and unable to reach emergency services, and in another it may report the wrong location to first responders after a crash. Both issues can delay help from reaching the scene.
