Also, 12 volt batteries still wear out. They tend to be smaller as they need no cranking ability but a bunch of manufacturers have had early failure on their 12 volt batteries. We went thru a 12 volt battery on our leaf at 4 years. Still pricey at 110 bucks although I never checked around much. I just got it from Nissan.
I do find it odd these old flooded start batteries are still being used in an EV.
Never read much on brake issues. Maybe if your driving style focuses on avoiding the friction brakes. Otherwise just drive.u
Don't need an EV tech to do tires, brakes, 12v battery swap, suspension, cabin filter, wipers.
Primary training will be to avoid the high voltage.
Re the brakes. From what I gather the people experiencing these problems are in winter zones where a lot of road salt is used. So far so good for us. With our new Y we probably use the brakes more anyway when pulling the trailer. 5 or 6 percent grades are fine with regen even with the trailer, but lots of routes have sections steeper than that. That keeps them fresh.
Tesla switched to an LFP 12 volt this year. Honestly don’t know what ours has. We keep a booster pack in the car. Came in handy on the leaf a couple times before we replaced the 12 volt battery. Unfortunately out of warranty.
