My 07' TLS with 140,000 miles is starting to nickel & dime me. In the last month the Serpentine belt, belt tensioner, power steering pump & both drive axles have been replaced. The battery was replaced in 2013 and so I decided to replace it fearing I'd get stuck somewhere this summer. A friend of mine is a Honda tech & did all the work & replaced battery with a Honda brand. Car was fine for about 3 weeks, then my wife & I left last friday for Lancaster, PA and took her CRV. We returned on Sunday & yesterday the Acura was dead. No power at all, completely dead. It took nearly 15 minutes to jump start it. I took the battery out & went back to the Honda shop & they gave me a new one. I had no lights on the dash board come on such as alternator or battery lights the last 3 weeks and everything seemed fine & no interior lights were left on accidently for those 3 days. Any one have any thoughts? I'm driving to VA tommorow on business & has me concerned. Also would you replace the alternator at this time? I've numerous posts with alternators going at 135,000/145,000 miles.

 

might want to check the Hands Free Link, as it likes to die and draw on the battery parasitically.

and that's what 10 year old needy cars do, they need your attention..so it could be your alternator... have you gotten these things tested, man?!?!?!

 

Haven't gotten the alternator tested, but my friend said that it's working fine unless the light comes on. There is a draw on the battery when car is off, but it's less then Spec, my son tested it.

 

Doubtful it's the alternator if it deid after sitting for 3 days... The alternator charges the battery, it doesn't draw from it.

 

Check the HFL like someone suggested, also make sure your headlight switch is in the off position and not the auto position. Probably would take longer than three days to go dead but it is recommended it be in the off position if letting the car sit for periods of time.

 

My son is gonna disconnect the HFL. Stupid thing doesn't pair with my I-phone anyway, I've had 3 different I-phones and none will pair with it.

 

id test the alternator by trying to jump it again place on on the + or red joint on the battery and then one of the alternator if it starts working and dies soon after the jump its the alternator

 

It is probably the HFL. If you don't use it, unplug it!

 

that's a new one too me

 

ding ding ding, this is the statement I am looking for... its a sign of bad HFL, I able to pair all 4 Iphone on both TL and the RL, and before the replacement it had hard time to recognize the BT connectivity.

 

I thought I remember it saying something about the battery with this message but it doesnt, and maybe it has nothing to do with the battery, but that was my assumption.

 

^^^LOL Justonjack is a 06 model therefore he does not have this paraphrase in the user manual book.

 

If you or someone you know has a multimeter aka volt meter connect that between the battery cable and corresponding battery connection with the multi meter setup to read amps. Do not turn the key on when hooked up like this because chances are the multimeter is max of 10 amps. So hook up the multi meter in series with the key off and after it is hooked up for 5 minutes or so (it will take a couple minutes for modules and ecu to reboot after being disconnected and re connected) you should see a small draw if there is something draining your battery. unplug fuses until the draw goes away. when you find the one causing the draw.....bingo. If you know someone that has a DC clamp meter this will be even easier.

 

It's most likely HFL
Stick your hand on the plastic area between the rearview mirror and garage opener buttons, it should be hot. During the winter you'd notice snow in that area of the window melted.
