Why is my Vauxhall Insignia's steering wheel vibrating at high speeds?

I recently noticed that my Vauxhall Insignia's steering wheel starts to vibrate when driving at high speeds on the freeway. The vibration seems to get worse the faster I go. What could be causing this and how can I fix it?

The most likely cause of this issue is uneven tire pressure or an unbalanced tire. Check the tire pressure on all four tires and make sure they are all at the recommended level. If the problem persists, take your car to a trusted mechanic and have them check and balance the tires.

Another possibility could be worn out or damaged suspension components. If your car has high mileage or you frequently drive on rough roads, it's possible that your suspension system has worn out and needs to be replaced. However, this can be a more expensive fix, so it's best to get it checked by a professional mechanic first.

It's also possible that your car's alignment is off, which can cause vibrations at high speeds. This can happen if you frequently hit potholes or drive on bumpy roads. Take your car to a mechanic and have them check and adjust the alignment if necessary.
