My '15 wrx engine light came on after I went to buy some shoes but it went away. Still getting it checked but the cruise control doesn't work and engine light came on. Happened after I turned off the car and when I tried to put the windows up the car started up again for some odd reason.
Still getting it checked out but best to wait until a minute or two before you plan to put your windows up if you forget.
Stupid me I'll wait 30 seconds or more if I forgot to put the windows up. It happened again and the engine light went away and cruise control started to work again.
