I thought about warrantying mine if it dies or fails to start, but I'll just throw a larger capacity in. It's a physically huge battery, I'm sure I can get something big in there.
I like this car and I plan on keeping it forever, so the cost of a battery isn't a big deal.
The batteries are stupid low capacity. For a modern vehicle. Sure, they don't take much to start any more, but the electronics take a ton
