#3 of 12 Re: Acura MDX 2010-2011 Battery Warning Problem [mdxbmrguy63]
May 02, 2011 (6:40 pm)
Got the first warning after about 2 weeks. Completely recharged the battery. The warning came back after another 2 weeks. Took it the dealer to have them check the battery. Battery tested out. They recommended driving it longer distances (I tend to take a number of small trips).
Last weekend I drove about 70 miles out of town. The warning indicator was on the entire trip down. Went off on the trip back. But the warning came back on Monday. It's still on despite just driving it for 40 minutes.
I've never had trouble starting the vehicle. Just loss of confidence. Shouldn't have worry about driving 2011 MDX with less than 2000 miles out of town.
#4 of 12 Acura 2011 MDX Battery Warning
May 11, 2011 (6:44 pm)
I have had my MDX about two months. Within the first week of driving, saw the low battery warning on intermittently. It seems to make no difference how far or how long the car has been driven. The warning comes and goes. Took it to the dealer who told me it's a "known software issue", to disregard the warning, and that Acura was "working" on a fix. In the meantime, there appears to be no way to distinguish between a valid low battery warning and one that isn't.
It will be interesting to see if Acura makes an effort to resolve the issue.

You probably have an intermittent failure within the regulator (internal to the alternator). The indicator/indication is that the alternator cannot supply enough current flow for energizing its own rotor.
Obviously not the case.

Just logging that we have the same issue with our 2010 MDX Tech. Mainly small trips and if the radio has been on during cleaning. The warning disappears by itself after some time on a longer trip that charges the battery. Very annoying.
#8 of 12 2011 Acura MDX - Replace Battery Warning
Mar 22, 2013 (11:36 am)
My 2011 MDX is doing this too. When I called the dealer, they just told me to bring it in, and acted as if they had never heard of this before. I also searched recalls etc. and can not find anything. Does anyone have a copy of the letter they received?

Our 2010 Tech/Ent. displayed this warning a couple of times, usually after the car had sat in the garage for two or three days. Took it the dealer and the battery checked out every time. It recurred even after they had applied the software patch related to battery monitoring. The dealer told me not to worry about it. Well, the next time I ignore the warning, I might end up with a real dead battery on a cold night in the middle of nowhere. Nice job instilling confidence in your customers, Honda! Guess whose product I'm going to buy next time?
#11 of 12 Same problem with 2008 TL - any ideas??
Sep 25, 2013 (11:21 am)
So....my husband has a 2008 Acura TL which has just 10,100 miles on it. (He's retired and only drives around in our little town). The car is practically new - still smells new. BUT:
It has the dreaded battery drain problem. About 6 months ago, he took it to the dealer for testing and they couldn't find anything which was draining the battery. The service guy just kinda mentioned that there was some talk that it might be the HFL, so we came home and did more research on the web. We disconnected the HFL and took it out of the car completely. Inconvenient, yes but not as much as a dead battery. Things didn't improve much - there were sporadic problems and after more research on the web we disconnected the trunk light in the middle of May 2013. We thought the problem was solved - no more dead batteries. BUT:
Today the battery is dead again. The car was just driven 3 days ago. Now what? We have this practically new car that we're slowly dismantling trying to solve this problem. Any suggestions? We really, really don't want to trade in this beautiful, almost-new car, and if we do, we probably won't ever buy another Acura because of this issue.

2009 MDX After 2 new Batteries and 7 visits to the dealer 80 miles one way and replacing the radio and the driver mirror among others and on the 7th visit it died on the Dealer. They tracked it to the left rear door lock that was trying to engage while unlocked all night long and activated other systems in the car drawing on the Battery and killing it overnight.
Dealer was patient as was I and they solved it.Each time I was given a loaner and Acura extended warranty covered all at 51K miles.
Needless to say my faith was very shaky but it works now
