I called a dealership in Cali. The parts dept said it cost 15k to replace the battery. I remember reading on this site 35k. Has the price dropped that much or were they mistaken. The parts guy said they have to make a replacement battery for up to 10 years. that gets me to 2024. at that point I can buy a new battery no matter if I need it because it will probably be the last chance to buy one. also, the price should be alot cheaper than 15k in 2024.
