The micro-switch in the driver's door lock may corrode and fail to detect that the door is open.
Loose steering coupling bolt can cause loss of steering
A steering coupling bolt may have been improperly tightened at the factory, which could allow the steering coupling to loosen from the steering rack.
Headlights May Be Misaimed, Reducing Night Visibility
Some 2023 GLC 300 and GLC 300 4MATIC vehicles are missing the caps that prevent headlight adjustment.
Rear Head Impact Protection May Fall Short in a Crash
Certain 2023-2025 Mercedes-Benz GLC and AMG GLC vehicles equipped with a panoramic sunroof may not meet a federal occupant protection standard.

A repair made under an earlier Mercedes-Benz recall may have left some vehicles with an incorrect main fuse box, one not designed for the vehicle.
Seats May Not Be Securely Attached in a Crash
Some seat rails on certain vehicles may not have been properly bolted to the vehicle body.
Loose dashboard bolts and heater wiring can cause fire or air bag issues
Some 2023 GLC 300 4MATIC vehicles may have dashboard-area bolts that were not tightened enough during assembly.
Fuse May Fail, Causing Power Loss or Fire Risk

Incorrect screws were installed on the high-pressure fuel pump, which may prevent a proper seal from forming between the fuel pump and the tandem oil pump.
