What could be causing my Vauxhall Insignia to vibrate while accelerating?

I have noticed that my Vauxhall Insignia vibrates while I accelerate, especially at higher speeds. What could be causing this issue and how can I fix it?

One possible cause of the vibration could be worn out engine mounts. Have a mechanic inspect them and replace if necessary.

Another potential cause could be an unbalanced wheel. Have your wheels balanced and rotated to see if that eliminates the vibration.

It is also important to check the condition of your tires. Worn out or unevenly worn tires can cause vibrations while driving. Consider getting new tires if necessary.
