> I don’t think that’s true, and am asking for a nuanced breakdown.
In my experience this kind of nuanced info is unfortunately pretty hard to come by. MFGs know it but have no interest in sharing it. Same for taxi operators (though the number of hybrids in taxi fleets is pretty staggering). Fleet operators usually only look at the first 5 years so longer term maintenance and repairs aren't studied all that rigorously. That said, here's a 5-year fleet TCO analysis where HEVs on average were 6k cheaper than ICE: https://www.afla.org/news/692431/The-Hybrid-Value-Propositio...
Also, here is an analysis from 2016 showing that the 2005 Prius had the lowest 10 year maintenance cost of any model. Toyota had only been making hybrids for 7 years at that point. That level of reliability for a new technology is pretty impressive: https://www.greencarreports.com/news/1104478_toyota-prius-hy...

speaking to this piece, it can be hard to gauge because its not all that common for companies to sell very similar trims in hybrid and non-hybrid. The two PSD hybrid examples off the dome are the corolla which is +$1500 for hybrid and the first-gen maverick which was -$1100 for the hybrid (before Ford knew the hybrid would sell like hotcakes, then they cranked the price up).
Perhaps Ford just wanted to burn cash but imo PSD hybrids are likely very competitive in terms of per unit cost, which would hopefully translate into lower repair costs. Toyota has also just switched to hybrid only for the Rav4, which is one of the best selling models on the planet. That would be a pretty bold move if they weren't very confident about the reliability and TCO (basically their entire brand value) or their ability to make money selling them (cost vs consumer value prop).
