Can a failed HFL system cause your battery to die?

I've searched a few threads on here and it talks about how it can. Mine started acting up then died about 2 months ago. In that time I have needed a jump twice. I had my starter and alternator tested and they came back fine. The dealer says if its that the cost is $317 with labor. The prices I see on here though are far higher, does this sound right/familiar to anybody?

Yes, if the HFL goes bad; it can have a parasitic draw on your battery.

if you dont use the HFL, you can just unplug it/remove it.
No more draw, voila!
