#25 of 64 2007 Acura TL battery dead if parked for 5-6 days
Jan 23, 2010 (9:57 am)
Hi was wondering if anyone else has run into this problem. I have a 2007 TL base and the dealership has indicated that with the standard battery drain (I think a .4) when the car is parked that you may have a problem starting your car if it is parked more than about 4 days. He indicated that the spec'd out battery Acura has only has so much capacity. This seems ridiculous as when my wife and I go on trips the car can sit at the airport for 7-10 days. So we have to take the other car a 2008 Chrysler that does start without issue.
I asked about them about replacing the battery with a larger capacity battery and they said they have to use the battery that Acura specifies which makes sense but the entire thing seems dumb.

I have an '08 TL that I have left parked in the garage for over a week at a time without a problem starting yet. I am aware if you have the navigation system (which mine does) that there may be a problem with the navigation system that would not turn off when you turned off the car and caused the battery to drain. I am concerned that at some point my TL will not start after reading all the complaints on the forums so I bought one of those self contained battery booster jumpers you can get at Sears and keep it charged and in the trunk. Others in the forum have also reported their battery drains on TLs that do not have navigation so there must be other issues with the electronics in the car that cause the battery to drain. It seems from reading in the forums that once you get the problem with the battery draining if it did not occur before, the problem could not be fixed and the battery would always drain down. Not sure that a larger capacity battery would resolve the problem, only prolong the time it takes for the battery to drain as the source of the problem is still there and need to be fixed. Acura needs to fix the root cause of the battery draining. This is a well known issue all the Acura dealers know about.

Thanks Trailhiker. My car doesn't have the Nav. The dealer did find that the blue tooth hands free was coming on by itself when the car was parked which caused a big spike against the battery. They did replace the unit but the problem has not gone away. They have blamed the after market remote starter I have that they claim is also putting a drain on the battery. So now I have had that disconnected. It's very frustrating I think something else is going on. But honestly I think the biggest issue is the standard battery doesn't have enough capacity to allow the car to be parked for days yet still start. I am curious what your climate is like, I am in Nebraska so we get a lot of cold weather and snow. The cold weather also zaps the battery. I do have three other cars (wife and 2 kids) all have remote starters along with different degrees of computer systems in their cars and their cars can easily sit for a week in cold weather and start without any problem. The dealer suggested that when I go to the airport on trips that I disconnect the negative battery terminal. I pretty much said "You've got to be kidding". Anyway maybe it's just a quirk with my 07 TL. Anyone else that has had similar experiences would like to hear from you.

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 64 2006 Acura TL window opens by it self when car is started
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.

Thanks Trailhiker for all the information and ideas. I appreciate it! I will let you know if I ever get to the bottom of this one.
#31 of 64 2007 Acura TL - starting problem
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 64 Intermittent Headlight Outages
Mar 24, 2010 (10:42 am)
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.

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

Me again..The ABS system on my 1996 Acura 3.2 TL is not working (which is fine as I do not drive in bad conditions) but the light on the dashboard stays on while running....is there any way to turn off this light...I would appreciate your advice. Newmark
