2008 Acura TL Owner Comments

problem #5

TL TL 3.2L

  • Automatic transmission
  • 125,000 miles


My battery kept going dead and I didn’t know why. Plus my Bluetooth wasn’t working. I found out even though I couldn’t get my Bluetooth to work the Bluetooth was draining my battery constantly, so I had a mechanic disconnect it. This stopped my battery from draining!

Bluetooth module went bad and continually drained the car battery. Unplugging the module (it lives near the rear view mirror) eliminated the battery drain but then, obviously, no phone/car connection. Eventually, had it replaced by the dealer after negotiating price (it was out of warranty). Since this is a common problem and well known to Acura, I was disappointed that I was charged at all. Not the first problem I've had with this Acura. Will definitely consider other options when the time comes for a new car.

TL Stock 3.2L V6

This problem seems to occur when I don't drive the car for multiple days. The dealer, this time, charged the battery. There is an electrical draw which the dealer can't seem to find or correct. Since I purchased this vehicle in 11/2008 the dealer has installed new batteries at no charge to me.

TL Sedan 3.2L V6

About a year ago, I noticed that my original OEM battery was starting to fail. Since the battery's age was over 5 years old at the time, I figured this was the problem & replaced it with a new battery. To my surprise, the problems continued. A few months later, I left my car at the airport for a week and when I returned from my trip, the battery was dead.

I noticed since then that if I don't use my car for a couple of days, the battery drains & I need to charge the battery. It became obvious that the problem wasn't the battery, but something that was draining the battery. I also found out from speaking with a few Acura owners that they've encountered the same problem.

I then did my own investigation & discovered that it's nearly a common problem among some Acura models from that decade & that the problem can often be caused by a faulty HFL module. From what I've read, Acura refuses to order a recall & it's a somewhat costly repair if you bring it to an Acura or Honda dealership (about $900 from what I've read). You may be able to find a used module via Ebay for about $150-200, but there's no guarantee it will work properly and it may take you up to 20 minutes to fix it on your own (by viewing a video of the repair on YouTube).

My extended warranty period ended in November 2014. I just verified the paperwork (AcuraPlus) and i don't believe the warranty would have even covered it. It's very frustrating since the battery drains constantly and i need to charge the battery every week or so. Since it appears to be such a common problem among various Acura models from a few years ago,

I honestly feel I'm getting ripped off if I'm the one who has to pay for that repair, which is why I've yet to have it done. If I do decide to get it repaired, I'll like it do it on my own since I don't feel like spending nearly $1000 for this.

TL Type S 3.5L V6

  • Automatic transmission
  • 125,000 miles

Car wont' start after sitting 2 days. The cause is the hands free link continually runs even with the engine off causing the battery to die. Very common on these cars.
