I’m about to start learning things myself if they don’t come up with more answers this time. I was a career engineer at NASA, and it’s really only the dreaded “voided warranty” threat that bothers me.
They replaced one battery already, and they seem to be lasting a year and a half. Pretty bad.
i do have some meters that could do some pinning down. I am not sure I trust the Service Mgr entirely because Edmunds.com had a long thread that included engines that quit flat in the middle of the freeway, and he denied hearing anything about that happening. Hey, at NASA, if we heard of something potentially catastrophic, we generally got really curious. true or false, we kinda wanted to know.
