Also Acura TL 2005 and same problem. Started by the HFL going into booting and nonworking mode. Then the first "Original Battery" died and after a few jump starts we went to sears and replaced it. Surprise the HFL started working again but we didn't use it as the quality if the conversation on it has always been poor. 6 months later the Sears battery died! went back to sears and the battery was BAD so it was changed under their warranty. Then a couple of months later that battery also died! went to the Dealership this time and oops the Cables to the battery are bad $200 replacement. A week later the Battery is dead again and back to the dealership and now the battery is BAD and can't handle the new cables!!!! another $100 for a new battery (number 4 in total). We asked about the HFL they claim it's not the source of the problem (I am convinced it is). We asked them to keep it for a couple of days and then test it again before they give it back to us. I will buy one of those battery meters that you can use in the ashtray plug to monitor the battery while it's parked.
ACURA should own up to this error and stop costing people hundreds of dollars and just replace there HFL (We already paid $400 in total which is what the HFL replacements costs)! In addition to the time wasted jump starting the Car!!!!
If the battery dies again I will just follow the manual and remove the HFL! this is disgusting
#44 of 71 Battery keeps draining--2005 Acura TL

I am now on my 4th battery in one year. 3 months ago I took it in and they spent several days examining the electrical system which they thought was draining the battery. $300 later they thought they solved the problem. Today it would not start again---put in 4th new battery. I drive car at least 6 out of 7 days----they think I don't drive enough miles to keep it charged and want to put on a battery tickler if it happens again. The problem usually surfaces after I have not driven it for 24 hrs. Also, my bluetooth stopped working about a year ago. They think maybe the bluetooth is causing the problem and say cannot disconnect it as it is part of a bigger system???

I just picked up a 06 tl for my wife and it has the same problem with the battery dying. I put in a new battery and it died within a few days of not being driven. I am a auto tech by trade and after noting that the conections ,grounds and charging system are all working properly I googled the symptems and found many forums discussing the hfl problem. checked the overhead with car off and sure enough it was warm. my hfl is still working properly just apparently not shutting off. I think rather then spend $400 on a new hfl unit I will try something different. I am going to source the hot wire in the plug going to the hfl and divert it through a on off toggle switch. I will get back to you guys as to if this works without disturbing any other functions , if so I will just tell my wife to always throw the switch when she is going to be out of the car for a extended period.

Hey, I was wondering how Acura helped you at the 800-382-2238 number? I am having the same battery draining problem and I've had my car for less than 4 years!

Thank you for your post and your link. I disengaged the HFL and the car had no more problems starting at all. Even if unused for 2weeks! The dealership should have done this for us or at least not charged us $300 between battery and cable changes. Thanks again.

Ever figure out what this issue was on the overheating, idling up? This began happening to my 2003 TL (currently has about 145,000 mi on it) about a year ago. The dealer can't figure it out as it has yet to "malfunction" when he has it.

i heard a motor running after the engine was shut off... i told the service people... a relay in the aC WASN'T SHUTTING OFF... the running motor drained the battery... many batteries...
after they changed the relay.. all was good.
for battery issues... listen for motors not shutting off... ask them to check the ac relays...
