On the "electrical" issues, I can't believe all those dash lights didn't trigger DTC(s) that would point to the problem. Is the dealer just guessing with the battery, then alternator/battery replacement? Those components can be separately tested too. Your statement that the dealer will replace the alternator/battery and then "continue searching" is not a great approach, to my mind. That transmission shift-clunk-lights you felt seems wrong. When you next talk to the dealer, mention specifically the torque converter solenoid failure noted in the transmission failure thread. Those of us with '17s are paying close attention!
