I am in Dallas. I had the car parked in the garage for a week at Christmas time when we had below freezing temperatures for almost a week and some snow and had no problem starting the TL after a week. Also the summers are hot, over 100 quite often so there are temperature extremes from hot to cold. I still have the original battery, bought the car in February 2008. I have asked my Acura service advisor about the battery problem and the response was the navigation system can cause this and also because of the electronics in the car, the battery does not last as long. He also advised me that the electronics are all somehow interconnected to each other so it is hard to determine what other electronic component may be causing the battery to drain. I dont accept the answer that the battery does not last as long because of the electronics as I have had Fords with just as much electronics and did not have this problem. Acura service runs a battery check every time I take by for oil changes, etc to check if the battery capacity is low. I know this will start happening to me one day so that is why I bought that battery jump starter at Sears (around $50) and keep it in the trunk. Something else that could be done (I do this with my tractor that I dont start for several months), I bought a trickle charger and connected it to the battery and put a quick disconnect in the wire so it is easy to disconnect as without keeping the trickle charger on it, the battery goes dead in a year or two and will not hold a charge. I am very interested if you do find the root cause of the battery drain.

#29 of 61 2006 Acura TL window opens by it self when car is started by dnicetl

Jan 26, 2010 (4:53 pm)

My rear driver window open by it self when I start my car so I have to drive with it open. The only way to close it is while the car is running and in park i have to open the driver door, then push the pull up on the button on the rear window, turn the car off, then close the doors. I think it has someting to do with the swithc located on the body that the door hits was it is closed. I check the fuses and some are missing and some are not even the correct amp indictated in the manual or fuse cover. The alram will also go off for no reason when parked. Any help or suggestions.

#31 of 61 2007 Acura TL - starting problem by tom07tl

Feb 16, 2010 (9:44 am)

In the past year I have had 3 times where the car would not start. In each instance everything lights up on the dash but the engine does not turnover. I have jump started the car and it started and then had no further problems.
 
The first time it happened I had left the radio on in the garage for an extended period. The second time it was only for less than 10 minutes and this last time I was hooking up a Bluetooth phone device in less than 5 minutes. This last time there was a starnge clicking sound and I knew something was wrong and then it wouldn't start.

#32 of 61 Intermittent Headlight Outages by brianjr

My headlights (low beams) intermittently go out on my 1999 Acura TL 3.2. Often one or the other, sometimes both. Occasionally, both go out when the turn signal is also in use or just deactivated. Usually turning the lights off/on one or several times makes both turn back on. Rarely (twice), I have had to pull over at night because they both went out and wouldn't turn immediately back on.
There is no condensation and the HID bulbs were in place for six months before intermittent outages. High beams work fine, even when one low beam is out.
I appreciate your thoughts.
Brian

I live in the Bahamas and have a 1996 Acura 3.2 TL - purchased in Canada. The DRL is not working (which is fine by me) but the DRL on the dash board stays on. Can I stop this by removing a fuse?...Thanks...Robert

My '04 had a drained battery about 2 1/2 years ago. They installed some part behind the nav unit pursuant to a TSB. Then that winter, due to a series of snow storms, my TL was parked for about 2 months. The battery died. The dealer recommended a brand new battery. I regularly park my car for a week or so at a time, but just recently, with vacation and such, it was parked for about 5 weeks, and bingo, the battery died again.
 
So it seems a week or so should be no problem, but anything over 1 month and I'll be on thin ice. I asked the BCAA guy who came to jump start it, if it is normal for a healthy battery to drain in a month, and he said it's possible due to all the electronic accessories and stuff in modern cars that will continue to drain the battery even after the ignition is shut off.
 
Now I know I don't even need to crank the ignition to know that it's dead. The doors wouldn't unlock with the remote, and the alarm blinking LED on top of the door would be off.

#36 of 61 Electrical problems?! by jenben

Jul 12, 2010 (5:39 pm)

I have an 04 Acura TL. 70k miles. my battery is draining due to my navi, radio and clock display ALL STAYING ON even after i've turned off the car, taken the key out and locked the doors!! the other day, I noticed it was the radio that wasn't turning off, and I dismissed it, after turning the radio off manually... the following day, my battery was completely dead. After having my battery jumpstarted, everything seemed to be fine, but noticed that while as it should, the radio needed to code, but the navi didn't and was staying on as well as the clock dash......
Any suggestions?

I had the same thing happen, My car is currently in the shop and they just called to tell me that it is the part the tells the Computer the cut the power from the Bluetooth and the Homelink and it draws ALOT of power and kills the battery. I have an 06 TL and have gone through 4 batteries. Thank GOD that someone took the time to find out the problem. Acura does know that they have this problem Call 1-800-382-2238 they can help with this problem.
