Berit Posted March 2, 2022 Share Posted March 2, 2022 All warning lights in my 2018 Subaru Outback came on this morning for no reason. It happened once before about 2 months ago. I was on a long trip , stopped to check what was wrong, but everything with the engine seemed fine, so I continued driving. When I started the car next morning, all warning lights were off. The car has been fine until this morning when it happened again Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 2, 2022 Share Posted March 2, 2022 Likely the diagnostic system has stored the DTCs. A psrts store or a mechanic can read them. post them here. sometimes, a failing battery or problems with a charging system can cause spurious codes. Even something like a loose or failing seal on a gas cap could do this. Quote Link to comment Share on other sites More sharing options...
