on an Acura MDX can be caused by several things: a faulty/dead battery, corroded battery terminals, a bad alternator, a damaged relay, worn battery cables, or wiring problems.

Your 2007 MDX is always reliable. Through snowstorms and backroad travels, your trusty SUV has gotten you a lot. Then, after returning home from a week-long cruise, you jump in, put your key in the ignition, and . . . nothing. So, you have the battery replaced, but a day later, your MDX’s battery is dead—as in stone, cold dead.
A dead battery can be frustrating—especially when you don’t know the cause. That’s where

What causes the 2007 Acura MDX battery draining problem?

If you’re noticing a problem with the car battery in your 2007 Acura MDX, your first step is to consider what is causing the battery drain—since there are many common causes. For example, if your MDX’s battery is dead after being parked for several days (or even weeks), it may just be that the battery can’t hold a charge. 
If the dashboard battery light turns on while you’re driving, however, this may indicate a bad alternator.

How to fix the Acura MDX’s battery draining problem

First, you’ll want to check to see whether your MDX’s battery is still holding a charge. Even if you’ve just replaced an old battery with a new one, do not skip this step—occasionally, a new battery can be a total dud.  
You don’t necessarily need to bring your MDX to a mechanic to have this done. Auto part retailers such as AutoZone and Advance Auto Parts, provide free battery testing. Obviously, if the battery is dead—either because it is old or defective—you’ll need to replace it.
On the other hand, if diagnostic testing shows that your MDX’s battery is sending out the correct current, you have another problem. While some can be relatively easy to address, others are more complicated.
Here are the most common reasons for battery drain:
Problems **not** caused by old or defective battery
Battery post corrosion (be sure to inspect your battery terminals and clean them off)
Bad relay or frayed/bad cable between alternator and battery, preventing the battery from getting charged
A light in the glove box or other area of the car that is not going off when it should (you can usually spot this yourself) after the MDX is turned off
A bad alternator—as with battery testing, many auto part retailers will test your alternator for free as well
An electrical problem somewhere in the MDX wiring—frayed or worn wire—that is causing the drain (unfortunately, it can take hours to identify a frayed wire)
Although car owners can do some basic diagnostics themselves, you’ll likely wind up needing a mechanic to correctly identify the underlying issue causing your MDX’s battery to drain.
