My 2013 expy is acting very strange. the speedo will drop to 0 and stay there while driving. On occasion it will lose all power completely for few seconds. The MPH to empty will then come up as _ _ _ MPH to empty. And the tire pressure monitor will light up and sometimes say tire pressure monitor fault. On occasion the wrench will flash or the check engine light. The AC is blowing full blast and will not change speeds, but does change temp in auto. It just seems weird that all this is happening at the same time. I plan on taking it to get checked for codes this weekend.
