Congrats on making it on your original 12V(s)! I bet there are more like you that have had no issues. I don’t think a dealer will replace anything under warranty without a complaint or error message.Over the weekend I had my rear passenger tire go flat rapidly while driving with the family. That’s another story with Jaguar roadside assistance. My I-Pace is sitting at the dealer and I was wondering if I should just get them to replace both 12v batteries while it’s there. They are original from delivery in 2018.
