My 09 tech (3.8) had its first hiccup this weekend. A series of events. First a flickering dome light, the next day no volume on the stereo or phone (screen looked right but no sound). Upon restart stereo worked but was intermittent for the day. And a couple of erratic window wiper swipes. Read most all of the comments about battery, radio head and software updates as well as flickering lights but I thought I'd ask the pros. What I've done....checked battery output....its 6 weeks old and shows 12.8 v and alternator shows 14.20. Tightened my battery ground, top terminal may have been 1/16th turn loose. Made sure wiper switch is set to "off" disabling the auto wiper feature. Started car with remote key in slot a couple of times...don't know why. So I'm wondering if there is a hard reset involving a disconnected battery? If so just how? Right now the gremlins are asleep but if they show their ugly face again I want to be ready for them. Thanks
