2008 2.5XT I bought several months ago. Seller had engine rebuilt and many systems updated around 115k in miles. Currently at 128k or so. I've put 3k of those on since I purchased. Everything post purchase was flawless up until a few weeks ago.

One day the check engine light comes on solid with traction control light and cruise and SI drive blinking. The car has a mild ECU tune. My local Subie specialist couldn't get his code reader to link up to the car but the code was cleared after he tried. Per the tuner, no reason the code reader shouldn't connect to the car. In fact I had to get the car smogged when I bought it and they passed it fine by hooking up to the OBD port. I bought a new gas cap to cover that base though. Several days go by and all is well. This morning as I'm sitting with my granddaughter waiting for the school bus with car running the traction control lights up, brake light, ABS light. Then check engine and flashing cruise/SI drive. I shut car off. When I turned it back on the clock is now not correct, lights still on. Shut it off again. Start car after bus arrives, no lights on at all on the way to work.

I'm guessing I have some type of electrical connection issue? Any guidance?

Thanks,
Jerry

Start with the ground connection at the battery. Make sure it isn't corroded and verify it's tight.
Then, use the built in display on the instrument cluster to read the stored codes and post back here with what you find.

x3 for battery, most likely a ground but the battery could be crapping out. Clean and tighten all connections with dielectric grease, if there are still problems see if you can get the battery and alternator tested. Usually crazy, flickering lights on the dash when you're trying to start the engine indicate a bad charge, so this randomly happening with things running means there is a connection that is cutting out.

It barely started last night and then was dead this morning after pulling both terminal connections and cleaning them up. I'm guessing the battery is faulty even though it shows 12.48 volts with my multimeter. I'll pull it and take it to the battery store tomorrow.

I'm sure this is fixed by now but the same thing just happened on my 2011 Outback and it was a 7.5 amp micro fuse in the engine compartment that powered the ECU. I checked the fuses with an ohmmeter and once replaced everything was back to normal. The problem started when I had Autozone replace the battery. Something happened that caused a short.
