  • I'm having the exact same issue in my 2004. Have you found a solution?
  • My 2004 just started the door and seatbelt thing today. Any solution? It's getting very frustrating?
  • My solution was some idiot running a stop sign and broadsiding me. Changing the flasher module fixed the majority of the problems but did not fix the ABS and traction issue
  • I drove my car a couple of miles, parked it for about 2 hours, drove 1/2 mile, parked 5 minutes, got back in and it wouldn't start. Ideas? it is 2010 TL with about 78 K miles. First battery defective and replaced under warranty around 45k miles ago. Absolutely no warning indicators.

    Hi - in order to help others narrow down what the problem might be, giving a few details about what happens when you try to start it would help. Is there just a click when you turn the key, or does it try to start but not turn over?

  • I've had my 2005 TL for over a year and never had an issue with the battery or electrical. Today it won't turn over at all; everything is silent; all lights are out; even the trunk latch won't operate! I am stranded! Any help??
  • Hi. I have a 2003 TL-S I bought from a dealer two months ago. One day it just would not start, like the battery was dead. No clicks, nothing. I got jumped, replaced the battery, and things were great for a couple weeks. Then one day same thing. But, I noticed when I opened the door, the light came on. I closed the door and it started like nothing was wrong. However the clock and radio needed to be reset, so it is clear there is some funky disconnect going on. The battery is fine. This happened again today and I cannot get it going this time, but the lights come on now and then, so I know the battery is providing power. Needless to say I am bringing this to the dealer tomorrow. I will post the solution when I know what they did.
  • Did you find the answer to this question? I have a 2008 TL and went to get in it today and it did the exact same thing. No lights, bells, trunk will not open, absolutely nothing. I thought, maybe my 5 year battery needed replacing so I went and bought a $115 battery today and still nothing. I am figuring it has to be a main fuse? If you have the solution, please send me an email at slea@martin-brower.com. Thanks.

    I used to have a 2008 tl type s. Similar battery deadness issues ..after 3 rd battery replacement..I drove and turned off ac.and radio ..I heard a fan going. I pulled over ..turned off engine...ac fan was still on..went to dealer told them...they told me ac fan relay switch wasn' t switching off..this was causing battery to die..
    They changed relay...problem solved...all good in the land.
    With these electrical issues..turn off radio and listen to the car and hear if there us a sound of something that isn't turning off when the car is off..
    I think Acura has a problem with relay switches not turning off and staying in the on open position
    .start with the ac.fan relay switch.
    ..then lights..inside lights..trunk lights etc..

    Good luck

  • Hi there. I am having the exact same problem with my 2004 TL. Did you ever find out what it is??

    I have a 2006 Acura TL. I am having the same problems listed except my battery dies within a couple hours of cutting the car off. I disconnected the HFL fully charged the battery, tested the alternator, tested the battery, bought a new battery and the battery is still draining that quick. No lights on the dash. Any Idea?
