I had a similar issue with my 07 TL about 2-3 years ago. I went down, had a new battery installed, about 4-5 months later, the battery was draining down to where it wouldn't start. Came on here for suggestions, unhooked the HFL. Not a single problem since.

 

If I remove the fuse for the HFL will it solve the problem or do I have to unhook the HFL unit?

 

As can be seen above, the HFL is on the circuit with other items, so if fuse is pulled, the other items won't function, so I'd unhook the HFl.

 

[QUOTE=kingxirol;12486970]Guys,

I bought an Acura TL '08 3 months back (still under factory warranty) and it's battery died yesterday! All I did was to come home and park in the garage. And the car was dead in morning. Well thats not the biggest problem. I got is jump started and battery cam back to life. The issue is now the Audio won't work. Pressing the Audio button just doesn't do anything. Neither do the any of the Load, Eject or AUX functions work. Does anyone has a similar issue and ....anytime the radio looses power you have to enter the radio code
