Can Electric Suction Doors Be Forcibly Closed?

[StIris]

Electric suction doors can be forcibly closed. Here is more information about electric suction doors: 1. Introduction: Electric suction doors refer to a configuration where the door automatically closes until fully shut if it is not properly closed. This is a common comfort and safety feature in luxury cars, typically found in models such as the Mercedes S-Class, BMW 7 Series, Audi A8, Audi Q7, Lexus LS series, and all Bentley models. 2. Working Principle: The working principle of electric suction doors involves an electromagnetic coil installed on the door frame (or door edge). When the door is opened, current flows through the coil, creating an electromagnetic field. Due to this magnetic force, when the door is close enough to the frame, it automatically seals shut.

I think power-closing doors really don't require forceful slamming. This feature is designed to automatically latch when you gently push it closed. Slamming the door actually causes impact, which over time not only wears out the motor gears but also easily deforms the locking mechanism. I've seen many people habitually slam doors, resulting in power-closing failure within half a year. The correct way is to push the door to about 2-3 cm away from the latch and let the motor pull it in. Actually, the same principle applies to power liftgates - just gently press it closed. If you're worried about incomplete closure, you can periodically spray some lubricant on the hinges, but never use brute force like with regular car doors.

Last year when I changed cars, I specifically opted for the configuration with power-closing doors, and the salesperson repeatedly reminded me not to slam them shut. At first, I wasn't used to it, and once when a friend got in the car, they slammed the door shut with a loud bang, and I distinctly heard the motor make a clunking sound. Later, I specifically asked the 4S technician about it, and they said the power-closing doors have internal sensing motors and gear sets, and strong impacts could cause gear teeth to break or sensors to shift out of place. Now, I always remind passengers to close the door gently. If there's accumulated water on the door frame during rainy days, I make sure to wipe it dry before closing to prevent moisture from corroding the circuitry. Although slamming it shut a few times in an emergency won't cause immediate damage, developing the habit of closing it gently can extend its lifespan.

The working principle of the power-closing door is to detect the door position through sensors, with the motor driving the latch to complete the final segment of the closing process. Forcefully slamming the door is equivalent to making the mechanical lock engage in a hard collision, not only bypassing the power-closing system but also generating unnecessary impact force. According to repair data I've reviewed, replacing the power-closing components at a dealership requires removing the entire door panel, with labor costs twice as high as those for a regular door. More importantly, long-term rough closing can deform the door seal strips, potentially leading to water leakage during rainy days. It is recommended to treat the power-closing door as an automatic sensor door—push it until you see it start to automatically pull in, then let go. During regular maintenance, remember to have the technician check if the door lock motor voltage remains stable.
