Why doesn't the Envision S have auto window closing when locking?

[StVera]

Envision has an auto window closing function, but it doesn't automatically close the windows when turning off and leaving the vehicle. Instead, it requires manual activation to achieve auto window closing when locking the car. Here is some information about the auto-locking feature: Overview: The purpose of the auto-locking feature is anti-theft. The doors will only lock after reaching a certain speed (around 15km/h) while driving, preventing potential door-pulling robberies during traffic jams or at red lights, providing a certain level of security. Disadvantages: The central locking system is a combination of mechanical and electronic devices. In the event of a crash, if the electronic components fail, passengers can still open the car doors to escape (provided the door locks are not damaged). However, if all occupants inside the car are unconscious, rescuers outside may waste more time trying to open the doors.

I've noticed many people asking why the Envision S doesn't automatically close windows when locked. This is quite common - some base models indeed lack this feature mainly due to limited hardware configuration. Buick might have omitted the sensor module for cost control, or the software might not have it enabled by default (requiring a dealership program update to activate). If truly unavailable, you can retrofit a control unit later for convenience - this won't affect daily usage safety.

When driving my Envision S, I encountered a similar issue and found the window-closing function hidden in the settings—you might need to long-press the lock button on the key fob or activate it via the car's app. It's not completely missing, but rather disabled by default to prevent accidental activation. I've taught fellow car owners to check the manual or update the software. If the function is genuinely missing, you can easily solve it by spending a little money to add an OBD module—it's really simple.

Safety first, some cars omit automatic window closing to prevent accidental injuries; for example, the base version of the Envision S excludes this feature to avoid pinching hands or pets and reduce the risk of malfunctions. Manual operation offers more peace of mind, saves fuel and electricity, making it a reasonable design for entry-level models.
