It is intermittent with mine, I see it about once a week or so. Although I'm thinking I should just fix it anyway.

Yeah, that's what's happening with me, too.

The "if tuner=3, force DC/Car" feature of Hijack is really working well at alleviating the bulk of the problem, so much so that I'm beginning to debate fixing it at all. Maybe I'll do it in the interest of verifying the digikey part number.
