The report I saw was in a newspaper and it cited a Consumer Report study. I found a Consumer Report study online but couldn't find the AP or BBC article that I would have read. I also list a few others that question EV's cost-of-ownership being cheaper.

I have no idea if the above articles have bias, but the outlets are pretty mainstream.
But I have read articles that claim
EV's are cheaper and I would question their cost of ownership #'s. One article used depreciation % comparison of EV's and ICE's to say they were comparable. But that's like saying a half-gallon of HyVee milk and Fairlife milk have the same cost of ownership if both have the same # of servings.
I also question the commonly used time frame of 5 years in many cost of ownership analysis. That might be great for people who buy a new car and sell within 3-7 years. But what about people who buy and hold? I like to own a car 10-15 years. In my case how will resale of an EV hold up if batteries have a life cycle between 12-18 years? My guess is the person or dealership that I sell my EV will demand a pretty significant discount if they anticipate the batteries will need to be replaced. No different than when I bought a house and the HVAC system was 15 years old- I reduced the purchase price by $12k anticipating buying a new system during my first few years of home ownership. As a side, the HVAC system died 2 years in.
I have nothing against EV's. I would love if they were the one size fits all solution. But at this point, I am not convinced that's true. And I also feel that too much attention is put on "green" auto's vs. "green" homes and other pollutants.
