What is the reason for the side mirrors not folding when locking the car suddenly today?

[John]

It might be because the side mirror knob was not rotated to the "AUTO" position when adjusting the mirrors, or the option "Auto-fold mirrors when locking the car" was not selected in the central control system. You can try setting the side mirrors first and then attempt to lock the car again. If the problem persists, then it is necessary to visit a 4S shop to check if there are any issues with the side mirror circuit. Generally, this situation is caused by either a setting or a circuit problem, which is not a major issue. More details are as follows: 1. Reasons for the failure of auto-folding mirrors: The failure of auto-folding mirrors could be due to circuit or setting issues. If the adjustment knob is not rotated to the AUTO position, the mirrors will not fold automatically when the car is locked. 2. Solutions for the failure of auto-folding mirrors: If it is a circuit problem, it requires inspection by a professional repair facility, which is generally beyond the capability of the car owner. You can also check if the folding mechanism of the mirrors is obstructed by any foreign objects, as this can also lead to the failure of the mirrors to fold.
