Thank you, again. Last resource to try figure out that problems. By the way, also check my fuel filler neck show no rust
From experience, any time that cruise control light comes on in a Subaru it makes me think of the ignition switch. You may have two issues at once though since the P0456 code is showing and the cruise control light is on. Do you notice any sort of lag during transmission shifts sometimes, or sometimes the engine sputters out while idling? If so, replacing the ignition switch will fix that unless there's some larger issue at hand.
