Some Smart Fortwo owners report experiencing issues with locking the rear glass hatch, which may stem from a malfunction within the latch mechanism itself. In certain cases, the hatch may close but fail to latch or lock, causing it to flap loosely while driving. Additionally, if the rear window isn't properly latched to the trunk, attempts to lock it may be unsuccessful. Owners should be aware that the rear-end door can be unlocked from the inside in emergencies if the central locking motor is defective. Some also find that the rear glass latch can get stuck, and actuating the latch multiple times may help. If the rear hatch cannot be locked, it may prevent the doors from locking as well, and realignment may be necessary, which is best handled by a dealership service department. Understanding the solenoid mechanism that activates the rear window latch can assist in troubleshooting these locking issues.
