What is the most common issue with the Vauxhall Insignia engine?

I have been experiencing some engine troubles with my Vauxhall Insignia and I'm wondering what the most common issue is with this model. Can you provide any insight?

The most common issue with the Vauxhall Insignia engine is a faulty camshaft position sensor. This can cause the engine to stall or not start at all.

Another common problem is a failing fuel pump. This can result in poor engine performance and even cause the engine to stop running.

I would also check the spark plugs and ignition coils, as these can become worn out and cause issues with the engine's performance.
