What is the reason why the BMW door buckle cannot bounce back?

The reason why the BMW door buckle cannot bounce back is due to rust at the lock hook or misalignment of the buckle position. Vehicle inspection before departure: Before setting off every day, conduct a comprehensive inspection of the vehicle, including checking for oil or water leaks; measure tire pressure to ensure it is appropriate; check the engine oil condition; inspect whether the spare tire is intact, etc. Be cautious when wading: If encountering waterlogged roads, be aware of the water depth and the condition of the road beneath before determining whether it exceeds the vehicle's passing capability. Avoid venturing into water if the depth exceeds half the height of the car's tires. Follow traffic rules: Do not race with other vehicles; drive safely according to traffic regulations and yield to pedestrians. Do not follow too closely; maintain an appropriate distance by following at the right rear corner of the vehicle ahead. When overtaking, pass from the left side of the vehicle ahead; avoid overtaking from the right or between two parallel vehicles.
After driving BMWs for so many years, I've found that when the door latch doesn't spring back, it's usually because the slot is clogged with dust/debris or the spring is fatigued - especially common in older BMW models after several years. My previous E90 had this exact issue; the latch would get stuck whenever the door closed, which initially scared me into thinking it was serious. Turned out it was just trapped leaves and grease buildup - cleaned it out, applied some lubricant, and it worked fine again. Cars parked outdoors often accumulate dust in moving parts from wind and rain exposure. Combined with BMW's precision-engineered springs losing tension over time, regular maintenance with cotton swabs and specialized lubricant makes this an easy fix. If the spring actually breaks, replacement is needed, but consistent upkeep usually prevents this. Never compromise on anything affecting driving safety.
As someone who frequently repairs cars, I believe there are three common causes for BMW door latch issues: First, the latch track gets jammed by small stones or dirt, preventing the spring from pushing it; second, the plastic components inside the door lock mechanism wear out, deform, or the spring rusts, losing its elasticity; third, insufficient lubrication increases friction, causing it to stick. I've helped many friends with this issue—using a thin wire to remove debris and applying silicone-based lubricant usually fixes it. BMW door designs are quite compact, and cold winters or humid rainy days can worsen the problem. Leaving it unfixed long-term can lead to gaps where wind leaks in, which is unsafe. Replacing a small part doesn't cost much but saves hassle. When inspecting, don’t forget to test if the door lock operates smoothly—prevention starts with small, practical steps.
I was startled when I encountered this issue, but after understanding the situation, I realized it's mostly a minor problem. The latch not springing back could be due to a loose spring stuck in the middle or deformation caused by slamming the door too hard. Try DIY first: clean the latch gap with a soft brush, spray some WD-40 for lubrication, and see if it can snap back into place. If that doesn't work, check if the spring is damaged and needs replacement—don't let dust accumulate for too long. To save time and effort, it's best to try DIY first instead of rushing to the repair shop.
