Since the start of winter, my battery keeps dying if I don’t drive the car for about 3-4 days. Is anyone else experiencing this or is it just my vehicle?
Check your proximity settings, if the car detects you nearby, it might turn on.
My Santa Fe can sit for 3 to 4 weeks without any issues. The Blue Link app only tells me the battery is low after that time.
What!? I didn’t know this could happen! Are you talking about the auxiliary battery or the hybrid battery going dead?
I’m not a mechanic, but it sounds like something might still be draining power when the car is off. You can test this by hooking a meter to the fuse box and pulling fuses to see which one is causing the drain. Maybe take it to the dealership. Is the car still using the factory battery?
I’ve heard that using your phone as a key can cause that because it keeps communicating with the car. You might want to turn that off.

Not just the digital key, but even the regular key fob can drain the battery. Hyundai told me that it keeps communicating, so I started bringing my fob inside instead of leaving it in the car. No more problems since.
Try keeping your keys in a faraday box in the kitchen.
I have the non-hybrid 24 XRT. If I leave it for a few days, the battery will be dead. It’s annoying, so I just keep it on a trickle charger now. I’ve had to replace the battery once because it was completely dead, but I just keep it charged now.
Looks like it’s probably the proximity sensor causing it. It’s frustrating that I can’t use it.
Do you pass by your car often? If you do, it might turn on and drain the battery even if you don’t drive it.
This seems to be a common issue with some hybrids. I was looking into getting a Maverick hybrid and found out that hybrids often don’t do well when sitting because the hybrid system stays active. I’m guessing that might be the case with all hybrids to some degree.
