This was my husband’s car, but he passed away two months ago, and it has just been sitting in the driveway. My daughter has been turning it on and spending time in it to feel closer to him, but then the battery died. I thought she might have left something on, causing it to drain. I jumped it today to get it started and checked the settings, but didn’t see any messages like I do with my own car. The lowest tire pressure was 32 psi. I know I should take it to the dealership, but the last time we dealt with them, it was a hassle, and they kept the car for a month. Both batteries are only a couple of years old. We bought the car used from a dealership in 2021, and when the hybrid battery had an issue, they said we needed a new regular battery and had to go to a Hyundai dealership for the hybrid battery. The hybrid battery was on backorder, and they kept the car for a month.

I believe this is a Sonata plug-in hybrid, which is what I have. My 12V battery was low recently, causing several warning lights to come on, along with a brake warning. Once the 12V battery was fully charged, everything went back to normal. Hopefully, that’s all you need as well.

It’s not a plug-in. It runs on gas, and I believe the hybrid battery charges while driving. The car died again, so I’m unsure how long I need to keep it running to prevent the battery from dying again.

A low battery caused an ABS error to appear.

The owner’s manual is really helpful.
