That's the same situation we have in upstate NY. Priuses, volts etc. that are getting to the age of needing HV system repairs are just not in good enough shape to justify. And even though the maintenance costs of these cars are lower when new, they have 2 powertrains to maintain instead of 1. So yes, hybrids tend to get scrapped sooner than conventional vehicles at least up north.
