Always used my pilot assist every day for last five years but yesterday it stopped working. No windscreen change issues. Today I’m getting lots of error messages saying thinks like city driving disabled, service required.
1) any ideas what’s caused the issue
2) any clues on how much going to cost to get it fixed
3) any suggestions on best place to get it faced- are we talking main dealership?

Thanks in advance for any help.
