Thanks for the good info. I did have the battery replace at the dealer and coded so that should not be the case.

As to the alternator going bad, wouldn't the fact that the systems come back on indicate that it is working by charging the battery back after driving for some time?

I will check voltage on the battery tonight as it's been sitting for a couple days while I wait for new tires to arrive. I read where it should be at least over 12.4v while running.
