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 steering connection to work loose from the rack and causing a partial or complete loss of steering control.
The center rear seatbelt is also affected: certain vehicles may have been assembled without the child seat locking function active, meaning a child restraint installed in the center rear position will not lock properly and can shift or come free in a crash. Separately, the infotainment control unit can reset without warning while the vehicle is moving, causing the instrument panel display to go blank and taking the speedometer and warning indicators off screen until the system recovers.
