NHTSA (USA)Medium Risk

What can fail
Headlights may be aimed too high, creating glare for drivers in oncoming vehicles.
What the fix does
Dealer will inspect and adjust headlight aim as needed at no cost.
The 2020 Mercedes-Benz AMG GLC43 has 7 recalls, the most serious involving the power steering control unit wiring harness, which can lose assist without warning or short-circuit and start a fire.
On the structural side, the left-rear seatback latch on vehicles with electrically operated rear seatbacks may not hold under load in a crash, allowing the seatback to swing forward and raise the risk of injury to occupants. Two separate issues affect rear visibility: the MBUX multimedia system software can cause the backup camera display to go black or restart on startup, and a separate software error can prevent the rearview camera image from appearing at all. The headlights on certain vehicles may be aimed too high, creating glare for oncoming drivers and reducing their visibility. There are also two recalls related to the automatic crash notification system: one where the system can dispatch emergency responders to the wrong location, and another where the system can become disabled entirely, preventing any emergency call from going through after a crash.
