So...I noticed what I thought was a slow leak on a tire for a few days. After taking it to a tire shop was told the rim was not aligned with tire. A day later...air leaking again. When I returned yesterday was told the TPMS sensor monitor was bad. Here's the thing, my MMI unit is not fully functioning so am I screwed by just ordering another one and having it replaced? I know the dealer will rip me a new one...
