Why can't the right rear door of the Mercedes-Benz GLA be opened?
2 Answers
Mercedes-Benz GLA's right rear door may not open because the child lock is engaged. It is recommended to check the sliding switch on the side of the right rear door. In most cases, this is a normal phenomenon. Generally, rear doors are equipped with child locks to prevent children from opening the door from the inside without adult supervision, which could lead to danger. The Mercedes-Benz GLA measures 4410 mm in length, 1834 mm in width, and 1611 mm in height, with a wheelbase of 2729 mm. Its dynamic and stylish design, combined with a simple yet high-tech interior and configuration, largely aligns with the aesthetic standards of crossover vehicles.
As a parent who frequently drives with kids, I've encountered the issue where the right rear door of my Mercedes-Benz GLA wouldn't open. The most common cause is accidentally activating the child safety lock. In the Mercedes-Benz GLA's design, the child lock is located either on the door edge or the center console—it might be a small switch or button, so try turning it off. If that doesn't work, it's likely that the door lock mechanism is jammed with dirt or rust. Mercedes doors are quite precise, and even a bit of mud can cause blockages—just gently wipe the door edges with a towel. Additionally, electrical system issues, such as low battery voltage or poor contact in the door wiring, can also cause the electronic lock to malfunction. My advice is to avoid pulling too hard to prevent damaging the door handle. Pay extra attention to cleaning the door seams during your next car wash to prevent this. If you're unsure, just take it to the dealership and let the technicians diagnose it with their tools—it'll only take a few minutes to fix.
