I'm curious to know if members who bought the ES300 have experienced issues with their hybrid batteries since gen 6 started back in 2013. Did any require replacement, and if so, under warranty or out of pocket. If they were paid for, how much was replacement cost?

 

My 2013 ES300h never had any issue so far. Not even a light bulb. The hybrid battery would probably need to be replaced between year 13-16 based on my Prius experience on a typical case. I am sure some cars will fail earlier or later but this would be outside any standard deviation on the HV battery failure normal distribution.

Anyway, the cost of a brand new OEM battery G9510-33050 is $2565 plus $500 for installation if you do not DIY.
