I have a 2019 Chevy Cruze with 23,000 miles. It is a 1.4l turbo. After a long road trip I began to notice a very odd sound that seems to be coming from under the dash. The best way I can describe it is that it sounds like a ticking clock. It’s not constant but I do hear it come on and off quite a bit while driving. Any ideas what this is. Is it urgent to get repaired?
