The complaint about the lights going out on Subaru Outbacks caught my eye and I thought I'd let you know that in 11 months and for no apparent reason both low beam globes had to be replaced on our 2010 Forester at a cost of $140. It's not just Outback models that have the problem.
We have had a number of reports from owners of Outbacks and other Subaru models and, you would appear correct, it's not confined to the Outback. We have forwarded them on to Subaru for their investigation.
