How to fix a malfunctioning Start/Stop system in a Vauxhall Insignia?

I have a Vauxhall Insignia with a Start/Stop system, but it has been malfunctioning lately. Whenever I stop at a traffic light, the engine does not shut off as it should. What could be the problem and how can I fix it?

The issue could be with the Start/Stop system itself or with the battery. I suggest checking the battery first, as a weak battery can cause the system to not function properly. If the battery is fine, then it may be a problem with the system's sensors.

Another potential cause could be a faulty connection in the Start/Stop system. I recommend taking your car to a certified mechanic who can analyze and fix any wiring issues.

Sometimes, a simple reset of the Start/Stop system can fix the problem. Consult your car's manual to find out how to do a system reset.
