I bought a 84 month battery names "TrueStart" with 84 month warranty in Oct 2020. In December 2024, it started to fail, had to jumpstart 3 times. Came to Toyota, hoping for a prorated new battery. However their proration is a joke. After 2 years, you get 50% of a cost discount. After 3 years, you get 25%. I asked them what would I get at the last year, and they had difficulty calculating such a small amount. In addition, they will sell you a battery for $198 which costs $127 at Toyota dealership next town. I asked to price match they battery and apply 20$ off coupon, but they said they cannot do both at the same time. So I ended up buying a new battery from them for full matched price and pay $50 to get it installed. What a shady business practice!
