Why can't the seat belt in Mercedes-Benz GLA be pulled out?

The reasons why the seat belt in Mercedes-Benz GLA cannot be pulled out are: 1. Improper use causing deformation of the seat belt, resulting in jamming at the entry and exit points; 2. Mechanical failure at the connection between the seat belt and the vehicle body. Taking the 2020 Mercedes-Benz GLA as an example, its body dimensions are: length 4427mm, width 1834mm, height 1610mm, with a wheelbase of 2729mm. The 2020 Mercedes-Benz GLA is equipped with a 1.3T turbocharged engine, delivering a maximum horsepower of 136PS, maximum power of 100kW, maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission.

Once when I was driving my friend's Mercedes-Benz GLA, I also encountered a seatbelt jam. I tried several times but couldn't pull it out, and later discovered that a coin had fallen into the buckle slot. The metal spring inside the seatbelt buckle can get jammed by foreign objects, causing it to lock, especially since Mercedes-Benz seatbelts are designed to be very tight. I suggest you try gently wiggling the buckle from side to side or use your phone's flashlight to check the slot for small debris. If the coin is stuck too deep, you can try using a thin wire to hook it out. Whatever you do, don't yank it forcefully—that could damage the buckle base. Now, I always check the seat gaps before getting out of the car to avoid spending unnecessary money on seatbelt repairs.

A couple of days ago, I found that the seatbelt in the new GLA couldn't be unlatched. Actually, the buckle slot in Mercedes-Benz models is particularly prone to getting jammed by small objects, such as cookie crumbs dropped by kids or coins from subway rides. Here's a handy trick: adjust the seat as far back as possible, press the release button on the buckle with your finger, and quickly wiggle the buckle side to side. If that doesn't work, try cleaning the slot with a toothpick. Also, moisture from car washes can cause the metal parts to rust and stick together—spray some WD-40 or similar rust remover and try again. If you still can't fix it, don't force it. The buckle mechanism in Mercedes-Benz is delicate, and DIY repairs might cause more damage. It's best to contact the after-sales service directly.

Last year, the seatbelt in my GLA suddenly couldn't be pulled out, and upon inspection, I found that the buckle tongue was inserted backwards. Mercedes-Benz seatbelt buckles have a right and wrong side, making it easy to insert at the wrong angle when in a hurry. Forcing it in too hard can deform the spring plate and cause it to jam. The solution is simple: first, adjust the seat to its maximum space, press the release button with one hand while holding the buckle with the other hand and move it back and forth to unjam it. If the spring plate is deformed, use a thin piece of metal to press against the edge of the lock hole to reset it. Now, I always make sure the buckle logo faces up before inserting it, and I haven't had any issues since. Regularly cleaning the buckle slot with a damp cotton swab to remove dust is also important.
