Ok, I'm not sure there's been a definitive thread for discussion, posting this so I'll start. Let's compile HV warranty lengths for by country/region. I'm curious to know if any other country/region offers an HV battery warranty as long as those in CARB states (10 years/150K miles). To keep things simpler, let's just go w/the HV battery warranty and stick w/Gen 3 (which I don't have) Prius. If you want to throw in hybrid components and emissions warranties, feel free to. US non-CARB states: 8 years/100K miles, no deductible US CARB states (e.g. CA, OR, NY, NJ, MA, etc.): 10 years/150K miles, no deductible
