The check engine light on the 2010 subaru forester is a catch all that is designed to alert you to an issue with the vehicle. It gets turned on when the computer in the vehicle detects an error on the vehicle and stores a trouble code. You can read that code with an obd scanner and this will tell you what the issues is. Common issues can include a loose gas cap, the engine misfiring, d***y spark plugs, vacuum leaks, low oil pressure, and nearly anything else. The light can also come on to remind you to get the vehicle serviced if you are nearing a mile stone. The check engine light is not often a major issue, but it should not be ignored either.
