My hesitation with hybrids is that I keep all the associated maintenance costs of an ICE engine. Now I have two power trains and energy systems to maintain instead of just one.
Well, hybrids sometimes get to replace the transmission with EV bits, like Toyota's system. Imagine an engine and exhaust system; now multiply the complexity by 100 and you have a modern transmission. Toyota hybrids (and GM/Chrystler/Honda) replace all that with a single planetary gearset, or with Honda, one clutch.
Other systems, think Volvo, pop the EV bits in the back of the car and replace where the drive shaft used to be with batteries. That seems like a decent trade to me as well. Still have a transmission, but at least it's not purely additive.
AND one man's added complexity is another's redundancy. If the charging module goes bad in a hybrid, you can still drive. Or if you run out of gas.
All that said... I still prefer EVs to hybrids. Do one thing, do it well, I say!
Modern transmissions can’t be two orders of magnitude more complicated than a modern ICE. If they are then I need to get into transmission design. An automatic transmission is basically just a series of planetary gears anyway. I would expect the marginal complexity between an ICE transmission and a hybrid transmission to be within a multiple of 2, but closer to parity. They’re both extremely reliable but an EV transmission (gearbox) will be even simpler.
Other than spark plugs, belts, oil changes and other such consumables I don't remember having to do any engine maintenance on my cars for the last 10 years. Of course, it helps that I am buyer of boring Toyotas and Hondas.
But all those costs are correlated with engine hours, in a hybrid used most of the time for commuting, ICE engine hours would be really low
A lot of maintenance items simply don't exist in a modern full hybrid. Typically there is no accessory belt, no alternator, no starter. Filters, coils, spark plugs and engine oil will last longer since the engine doesn't run nearly as hot (usually it's "atkinson" cycle) and isn't used constantly.
I'd avoid any car with two powertrains, but there are systems that have an all electric powertrain with the ICE being used as a generator instead. It is a simplified system that, if designed correctly, can allow all battery or all generator to move the vehicle.
That is just a meme without substance. The ongoing maintenance cost of a mature Japanese ICE drivetrain is negligible compared to the overall operating costs of the whole car. There is a reason why Toyota hybrids are by far the most popular cars for Uber drivers.
You do, but at least repair costs should be low because typically you won't put very many miles on that engine.
Suppose 90% of your miles are electric. After you've put 250K miles (400K km) on the car, you've only got 25K miles (40K km) on the engine. Rarely do you have significant engine trouble at that mileage.
Also, the engine design can probably be simplified if it's just acting as a generator. You don't need a turbo to provide extra bursts of power. Nor things like variable valve timing for good performance across a wide range of RPMs. Maybe you could even use an air-cooled engine like old VW Beetles and Porsches.
But how often do you have issues with the engine. My last 3 cars never had a single engine issues for at least 175.000 miles. Its very rare today to have big engine issues.
Clearly you're not buying quirky over-engineered German cars loaded with exotic but mostly useless luxury features. They are well built and last forever, but typically require very frequent tinkering to keep them working.
It's the powertrain that's far more apt to be the problem. Hence a plugin hybrid generator style should be far simpler than a system with both an ICE and electric powertrain.

Only other thing is that it is consuming more oil now so needs topping up every few thousand miles.
