The 2023 Mercedes-Benz GLC 300 4MATIC has 3 recalls, the most serious involving a steering coupling bolt that may not be properly tightened, allowing the steering column to disconnect from the rack and causing a complete loss of steering control.
The second recall affects vehicles equipped with a panoramic sunroof: in a crash where a rear passenger's head strikes the C-pillar, the pillar may not absorb enough of the impact, raising the risk of head injury. The third recall is a lighting compliance issue specific to this model year, where missing headlight adjustment prevention caps can allow the beam aim to shift out of position, reducing visibility for the driver at night.
