2020+ Audi A4 reliability?

I’m considering buying a 2020+ Audi A4 (pre owned) I’ve heard mixed things on Audi’s reliability and part costs, looking to hear from owners themselves.

1. Are Audis really as expensive as people say they are for maintenance & repairs?

2. Would an Audi A4 last me upto 150-200K with regular expected maintenance

3. Any known issues with the A4’s I should be aware of?

If you have other recommendations I’m happy to hear those as-well, thanks in advance everyone!
