I have a 2009 3.0 with 150k and at the same time this past weekend my parking brake malfunction light came on ,both key FOB's do not lock/open the car and all my radio button presets were wiped out.

I haven't yet been able to bring it in anywhere for codes but I am wondering if anyone else has had this happen before I rip into the brake actuator.

Maybe the battery i son the decline or the valet guy at the hotel f'd things up??

thanks in advance
