2018 with 38k. OEM battery just literally died last month. But I do a LOT of in-car parking (sitting at Stanford University, where I live next door to) but with the car on. I mistakenly had done Acc when I first got the car and discovered how fast Acc drains the battery off. Also sometimes I use the car as portable A/C space easily running it 2-3 hours parked. I wonder if that causes any issues on the 12v battery.
