Why is my Vauxhall Insignia making a loud knocking noise?

I recently bought a used Vauxhall Insignia and noticed that it makes a loud knocking noise when I accelerate. This noise seems to be coming from the front of the car. What could be causing this and how can it be fixed?

Your car could be experiencing a problem with its suspension system, specifically the ball joints or control arms. It is best to take your car to a mechanic for a thorough inspection.

Another possible cause could be a failing engine mount. This can be fixed by replacing the faulty mount, which should be done by a professional mechanic.

It is also possible that the knocking noise is coming from a loose exhaust pipe. This can simply be fixed by tightening the exhaust pipe bolts or hangers.
