Here's a belated welcome to SaturnFans, canela! I noticed that you had another post from this past November which received no repsonses. I wish I could be of more help, but I know nothing about the 3.6L engine in these Sport Utility vehicles. Frankly, there aren't many Outlook owner members due to the demise of the Saturn brand with GM's bankruptcy/bailout in 2010. I suppose it might be worth finding a forum for Chevy Traverse, GMC Acadia, or Buick Enclave owners as those vehicles shared the same platform, engine and transmission with the Outlook.

A couple of threads may have some relationship to your concerns here.

Here's one with the list of Technical Service bulletins for the Outlook.

What's my opinion of your situation? I don't have confidence to suggest that a BCM replacement is the right choice to make to correct the problems you're experiencing. I will admit that a causal connection with the BCM and your symptoms is possible, but that's as far as I can go in recommending any type of DIYer repair on your Outlook. Members in the L Series Forums have described even wilder problems with a failing BCM.
