I've had this happen with other cars and motorcycles when my battery wasn't charging properly due to corroded/loose terminals. Carry a voltmeter with you in the car and next time it happens, check the voltage. Better yet, hook up a volt meter permanently to the battery. They're cheap: available online like this one: CLICKY HERE. I have one of these and it has it's own on/off button to prevent battery drain when car is off. No more surprises with voltage.
Starting issues
My wife's 2014 Hyundai will sometimes refuse to start. She get a "battery drain" code on the dash. New battery, just happens every 3 or 4 months. Let it sit for a few hours after it not starting, starts right up. Any ideas?

New battery, not because of the starting issues, just time. When it will not start and shows battery drain, headlights are bright and all electronics' work just fine. Power window, everything. I don't think it is a battery issue.
Still considering the battery possibility, cleaning the terminals is quick and easy. It eliminates a huge variable. Checking the voltage, especially during the times this occurs, eliminates another. A bad (even though new) battery, faulty alternator, or corroded posts can cause this issue. A volt meter will likely reveal this as it happens. They're so cheap and easy to install. Sad that they've fallen out of favor and we get "idiot lights" instead.
Another possibility with some Hyundai's is that your GPS got stuck in "search for satellites" mode: rare but possible. It can draw a good bit of power. Unplugging its fuse for a little while to reset it might cure the problem.
Going a bit farther, a loose serpentine belt can cause this. Is the tensioner doing its job? Is it tight? A local auto supply store can do a battery load test to test the battery's amperage delivery while under load. While you're there, they can check to see if the computer has thrown any codes. These are the only possible solutions we can offer beyond taking it to the pro's. You may indeed be right about it NOT being the battery, but these old school "fixes" are easy to do and may save you some money and headaches.

I've had a poor ground cause similar issuesNew battery, not because of the starting issues, just time. When it will not start and shows battery drain, headlights are bright and all electronics' work just fine. Power window, everything. I don't think it is a battery issue.
IF she is parking it for more than a week, it might be battery drain. The car has a lot of stuff that never turns off- it is always looking for a signal from the fob, and even from cell phones. I have seen this complaint on the forums here.My wife's 2014 Hyundai will sometimes refuse to start. She get a "battery drain" code on the dash. New battery, just happens every 3 or 4 months.

We addressed this on another thread, but I should repost the idea here. I'd suggest a volt meter. It should help during these non start times by eliminating one big variable. You can plug one into the cigarette lighter receptacle ad just leave it there. I bought one here: CLICKY. Price was amazing....2014 Hyundai will sometimes refuse to start...

My cell phone battery lasts three days if screen is off. The car battery is about 1000x the size; and ought to last a lot longer than a week. My cell phone also does a lot of stuff even if the screen is off- like broadcast its position so it can be discovedred.IF she is parking it for more than a week, it might be battery drain.
