Why does my Vauxhall Insignia engine stall randomly?

I have a 2015 Vauxhall Insignia and recently I have noticed that the engine stalls randomly, even when driving on a smooth road. What could be causing this issue and how can I fix it?

This could be due to a faulty ignition coil or spark plugs. I would recommend getting them checked and replaced if necessary.

Another possible cause could be a clogged fuel filter. Try replacing it and see if that solves the issue.

Have you checked your battery lately? A weak battery can cause the engine to stall. Try getting it tested and replaced if needed.
