My son is away at college with his 2008 Outback. While he was driving, he made a turn onto a side street and he said he lost the power stering and it felt like both brake and gas peddles were stuck. The car was then idioling rough and he pulled over and turned it off. He restarted it and went back home. He put a OBD readers need and got a message "No Power Train". DCS unattached. There are no warning lights on and the code went away. Any help on what this may be would be greatly appreciated.
