I’ve been getting this message way more than I think I should. I’m in the Pacific Northwest, so it’s not super cold. I get the battery is used for a lot of electronics, but if I don’t drive it for about four days, I get this warning. Is this happening to anyone else? Should I use a trickle charger to avoid this?
Maybe your battery is on its last leg. How old is it?

The battery tested fine, but I saw in another thread that replacing it anyway fixed the issue for someone else. I might just do that this weekend.
@Wilder
Do you take a lot of short trips? Those can drain the battery without giving it enough time to recharge properly. A trickle charger might be a good idea regardless.

Agreed, a trickle charger can make a big difference.

Not all my trips are short. I drove 45 minutes yesterday and still got the message after parking. 
@Wilder
If that’s the case, it’s probably just the battery wearing out. Try cleaning the terminals first, but if that doesn’t help, it’s likely time for a replacement.
Forgot to mention it’s a 2018 Platinum model.

How old is the battery? If it’s the original, it’s overdue for sure.

It’s three years old. I also left the hatch open last summer for a few hours, and the cargo light drained it. So yeah, it’s been through a lot.
Mine started doing this after I added a GPS tracker to get an insurance discount. Could be something like that draining yours?
Does this happen right around the fourth day of not driving? If so, it’s probably just the car going into deep sleep mode. Batteries over 3-4 years old often can’t handle that as well.
Have you reset your battery management system? If you replace the battery but don’t reset the system, the car won’t know the battery is new. You might be able to reset it in the car menu, or a mechanic can do it with a scan tool.
@Harlow
Thanks for the tip. I’ll look into how to reset it.
