What is the cost of the Hybrid battery?

Hello, So, everything on that vehicle will always be expensive to repair, and the hybrid battery is likely one of the most expensive repairs you can run into. 7 years is average lifespan as well. 16k sounds high, but it does not surprise me at all. My advice to you is to seek a third party, used or salvaged battery, or find a service to replace the bad cells in yours. Shipping costs will likely be high, but I couldn't see any other option costing 16k.
