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.

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.
