I had to replace the inverter
I had to replace the inverter on our 2012 Prius V within a year after buying it. Got it used in 2016. However, I got the money back from Toyota when they announced the recall. They covered the whole repair I had paid for including the used part I bought off eBay.
It has 191000 miles now. Unfortunately the smart key system has an issue, a short somewhere in the wiring and so the key fob remote doesn't work. Dealership wanted over $2,000 to fix it and two other places couldn't do it. I'll be trading it in soon.
