THIS. The ARIYA is the first EV they've widely released (last year) with any active thermal management. I live in AZ, and all my friends with Leaf's all have had to have their batteries replaced at least once.
All my Chevy based EV/PHEVs have had great battery life (so far) - knock on wood.
I'm also in AZ. What's surprising to me is I get slightly better range in the summer months.
Probably depends on the climate and use case… early EVs with no thermal management seems to last forever in coastal areas with mild climates, and slow heavy traffic
