2018 odyssey EX-L. Bought in November 2020 as Honda certified.

Battery died about a year ago (after kids left light on), I jumped it and then it's been fine for a year or so.

Yesterday, the battery died during church. I jumped it with a battery pack jumper and drove home.

Tonight, my wife drove it to the grocery store and then needed to jump it again with the battery pack to make it home.

I then immediately took the van to costco for a new battery, I thought costco would just swap it out for me real quick but apparently they dont. So, I go to get in the car to go home and the car won't start. I try to jump it, battery pack is dead. Costco employee tries to jump my car without success. I then borrow some tools from costco and put the new battery in. Lights in the car come on, everything seems fine but the engine won't start. No clicking or anything like that. I had to call a friend to come pick me up and take me home...

The car is only 4 years old, has less than 60k miles on it.
