The 2025 Mercedes-Benz GLC 300 has 3 recalls, the most serious involving a steering coupling bolt that may not be properly tightened, allowing the steering connection to the rack to loosen and causing a potential loss of steering control.
Vehicles equipped with a panoramic sunroof also have a structural concern: in a crash where a rear passenger's head strikes the C-pillar, that pillar may not absorb enough of the impact, raising the risk of head injury. The third recall affects the infotainment control unit, which can reset while the vehicle is moving and cause the instrument cluster display to go completely blank, taking the speedometer and warning lights with it until the system recovers.
