What can fail
Headlights may be aimed too high, creating glare for drivers in oncoming vehicles.
The 2021 Mercedes-Benz AMG GLC43 has 7 recalls, the most serious being a fuel pump that can shut down without warning and cut drive power while the vehicle is in motion.
The restraint system is also affected: seatbelt pretensioners on certain vehicles may not perform properly in a crash, reducing the protection the belt provides at the moment of impact. Two separate recalls cover the automatic emergency call system. In one case, the system may dispatch emergency responders to the wrong location after a crash; in the other, the system can fail entirely, preventing any call from reaching emergency services. Both failures delay help when it is most needed. Headlights present a pair of concerns as well. On some vehicles the headlights may be aimed too high, creating glare that blinds oncoming drivers; on others, a non-watertight electrical connection can allow moisture in and cause the headlights to fail altogether, leaving the road dark ahead and making the vehicle harder for other drivers to see. Rounding out the list, a software fault in the multimedia system can cause the backup camera display to go black or restart when the vehicle is put in reverse, eliminating the rear view just when it is needed most.
