The 2026 Mercedes-Benz GLC 300 4MATIC has 3 recalls, the most serious involving a steering coupling bolt that may not be properly tightened, allowing the connection between the steering wheel and rack to loosen and causing the driver to lose steering control.
The center rear seatbelt may have been installed without the child seat protection function, meaning a child restraint will not lock correctly in a crash and a child in that seat faces a higher risk of injury. There is also an electrical concern: the infotainment control unit can reset while the vehicle is moving, causing the instrument panel display to go blank and taking the speedometer and warning lights off screen.
