Owner of high-end hybrid EV. Hybrids are still new to many car garages, which means skills to fix issues are not optimized. It took 3 weeks and $9k to figure out my hybrid wouldn’t start due to a faulty basic EV component (fortunately under warranty).

In addition cost of fuel cell replacement pushes up cost and risk of ownership and can be common at 70-80k miles.

I hate to say it, but I am actually considering a trade in for gasoline.

Battery-only EVs have a much simpler drive train, and longer-lasting batteries.

Hybrids are not simply EV+ICE, they have very different kind of batteries (low-voltage, high C-rate).

In a hybrid, you have a battery that is 1/10th of the size, so the battery works 10x harder – needs to discharge at higher rate to move the car by itself, and usually there's no room for proper cooling of the battery.

In a BEV you have 10x more modules working at 1/10th of that rate, and there's battery management system keeping it at optimal temperature.

Batteries live longer when they're kept in 20-80% state of charge, and don't like to be cycled deeply. Small hybrid batteries get charged and discharged fully quite regularly, while the same distance needs only 10% of BEVs battery.
