Battery Drain...

I've replaced the battery and had the alternator checked, but if I don't drive my 06 for a day, the battery goes completely dead. Even the remote won't unlock the doors it's so dead. I never leave lights on or anything that would be an obvious cause, but I was curious if anyone else ever had this same issue. Thanks for any advice and information.

Hfl stands for hands free link or blue tooth. This is a very well known issue that drains your battery since the Hfl remains on. Google "06 TL hfl removal". It's very easy to disconnect and be done with the problem. I just left mine disconnected since I don't use it or the voice controls for the nav.

Took me maybe 10 minutes to access the HFL, disconnect it, and put everything back to normal. Hopefully this fixes the problem. Thanks!

Wish I would have known this in Nov. Three trips to Les Schwab, a battery, one trip to another auto shop, an electrical test and eventually disconnection of HFL solved my problem, smh ~300 dollars later.
