I have read several entries here about the check engine light going on that seem similar to my situation, but would like to outline here what happened to me. I have a 2017 Forester Touring, purchased used, less than 20K miles. Parked car in garage last night. Started this a.m. and the check engine light and a sound and a car on a slant light and a car on a bumpy road light and all CAPS EYE SIGHT in center lit and and and. What the heck could have happened overnight!!? I took to my mechanic today. He read the codes and said SEVEN code indicators like "loose gas cap" (was not loose...am extremely aware of this and had driven the car for a week since I last filled up). Also low tire pressure. Etc etc. Since I am an old IT person, first thing I am thinking is that some electronic component has gone berserk. I think it is a poltergeist! My mechanic says to take to the dealer, which I will, but would love to know what you think! (P.S. Please speak in plain language as I am not a car geek...thanks!)
