Why is the steering wheel of my Audi A6 shaking?

Lately, I've noticed that whenever I drive at high speeds, the steering wheel of my Audi A6 starts shaking. It's not a consistent shake, it comes and goes. What could be the possible cause of this issue?

Hi Jenna, I'm sorry to hear about this issue with your A6. This could be caused by a number of factors including misaligned wheels, worn-out tires, or faulty suspension components. I would recommend taking your car to a certified mechanic for a thorough inspection and proper diagnosis.

Hey Jenna, it's important to address this issue as soon as possible to avoid potential hazards while driving. It's possible that your wheels need to be balanced or your steering components may need to be checked. I suggest having a mechanic take a look at it before the problem worsens.
