The 2023 Mercedes-Benz GLC 300 4MATIC has 3 recalls, the most serious involving a steering coupling bolt that may not be properly tightened, which can allow the steering coupling to separate from the rack and cause a sudden loss of steering control.
The second recall affects vehicles equipped with a panoramic sunroof: in certain crashes, the C-pillar behind the rear doors may not absorb enough impact force when a rear passenger's head strikes it, raising the risk of head injury. The third recall is a compliance issue specific to this model year: the headlights are missing caps that prevent accidental or unauthorized beam adjustment, meaning the aim can be altered and point too high or too low, reducing how well the road ahead is lit at night.
