Mike: I have the exact same problem on my 2004 TL. When you press the brake, the high mount stop light in the rear window is dim, most of the time. If I start the car, ocassionally I can get it to go full brightness. I did a voltage check and when dim only 7 volts, when bright approx 13 volts. So I know the problem is not the light itself (all 16 LCDs work on bright - ocassionally). Did you find the cause of your problem? Thanks. Bill

Occassionally my 08 TL will have trouble starting--very random. Has anyone else had this problem? It is as though the battery is not strong enough and the car will not turn over, but thenm magically starts.
 
Acura replaced the battery and the cables attahed to teh battery or so they say. I know they at least looked at the battery because they forgot to reinstall the cover plate.
 
The problem went away for a year, but is now back in full swing.
 
This happened from day one of owning the car with zero miles on it.

I solved my high-mount brake light problem, The solution was to replace the brake light switch, which is located on the brake pedal. The switch was less than $7.00, which I purchased thru Rock Auto. The switch is made by Airtex, part number is 1S5785. It was very easy to install - total was about 10 minutes. Bottom line - the switch went bad. (P.S. Acura dealer wanted $109 to trouble shoot the problem and this fee would not be applied towards the actual fix.)

On the dashbord yellow light DSL is on all the time, but no light on the balbs.
Check the fuses all OK, balbs are OK. Normaly after i release the parking brake, the light came on and the sign DSL came off. Now the DSL is on all the time and no any light on the balbs.
Please, if any body know what is that or had similar experience, please lets me know. Thanks.

#25 of 61 2007 Acura TL battery dead if parked for 5-6 days by miketl07

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.
