What is the reason for the BMW X5 window glass going up and then coming back down?

The reason for the BMW X5 window glass going up and then coming back down is: 1. Fault in the car's anti-pinch function; 2. The window lifter's steel wire rope is loose or broken. Taking the 2021 BMW X5 as an example, it is a mid-to-large-size SUV with body dimensions of: length 4930mm, width 2004mm, height 1776mm, wheelbase 2975mm, and fuel tank capacity 83l. The 2021 BMW X5 has a front suspension of double-wishbone independent suspension and a rear suspension of multi-link independent suspension. It is equipped with a 2.0T turbocharged engine, with a maximum horsepower of 265ps, maximum torque of 400Nm, maximum power of 195kW, and is matched with an 8-speed automatic transmission.

I've encountered many similar issues, and the most common reason for the BMW X5 window glass closing and then reopening is the activation of the anti-pinch function. The system has sensors to detect resistance, preventing hand pinching. Once it senses an obstacle, such as dust on the window frame, a stuck card, or debris in the guide rails, it automatically lowers the window. Additionally, switch malfunctions or poor button contact can send incorrect signals, causing the glass to move up and down repeatedly. It could also be due to motor overheating or wear leading to unstable operation, or even a software bug, such as incorrect module settings. It's recommended to first check the cleanliness of the window frame and try the manual press reset method. If that doesn't work, take it to a professional shop for computer diagnostics—avoid disassembling it yourself to prevent further damage to components.
