Agreed! I often think back to 1992 when I foolishly bought a 1988 M6- at the tim I could have bought a brand new top spec Accord, Camry, or Maxima for similar money. I can but wistfully imagine the exquisite driving experiences I let slip away.
Toyota's new electric oil pump.

do you understand how different hybrid system is, vs s&s system in nonhybrid car ?

Maybe not. Perhaps you can explain?

therefore maintenance comparison to standard s&s car is pointless .
there are few exceptions, where strong 48v alternator is able to spin standing engine, and/or with proper crank angle just one spark will start engine.
physical starter is just for backup.
You are treating that rental like it's your own. Very commendable, you are one in a thousand. Most people who lease cars do the absolute minimum to keep them going.
I’m OCD. I look at it as someone else has to buy this after it’s turned in and that’s messed up to do just bc it isn’t mine. Someone’s grandma might buy this. Plus when I pay $1,000 a month for this car, I’m not going to cheap out.

Thanks so much for the info and links. I learned a few things.it has no starter to break. those e-motors are zero maintenance.Hybrid Synergy Drive - Wikipedia

The Honda Integrated Motor Assist system uses a 144V DC motor coupled to a clutch or torque converter(hence why the 1st generation Insight and Civic Hybrid had stick shifts as an option) but still has a 12V starter as an fail-safe. A bit similar to THS, but closer to a ISG system that so happens to provide some more motive assist than GM e-Assist/FCA e-Torque. The JDM versions of the Prius as well as the 1st gen Ford Escape also had a emergency charging button for the HV battery.it has no starter to break. those e-motors are zero maintenance.Hybrid Synergy Drive - Wikipedia

Regular start/stop still uses a 12V starter unless it’s a BMW 7er/Mercedes S-Class with lithium batteries and 48V electrical. GM really wanted the 48V system to be a reality - they teamed up with Johnson Controls for the Inspira system used in the e-Assist Malibu/Impala and Silverado. Those used a 48V belt starter-alternator.
True but it's important to remember that manufacturers usually aren't stupid. Everyone seems to assume they are using the same starters in ESS vehicles as they do in vehicles not so equipped. This is not the case, the starters are built more heavy duty to stand up wo the additional workload and heat.it has no starter to break. those e-motors are zero maintenance.Hybrid Synergy Drive - Wikipedia

You make a lot of false assumptions. Please go on.
Enlighten me?
time to put pink glasses down.
they are doing stupid things, just because to fit into ever increasing strict co2 rules.
no carmaker is without faults. and no carmaker has only a happy customers.
It wasn't back then.
It's just that as long as the engine is turning, the oil pump is. With electric, there's the 12v system, wiring, switch, motor parts, etc. More to fail. Vehicle co's seem to either not realize, or not care about that solid fact.
It’s chain driven so my comments are moot now really. The electric pump theory was debunked.
This thread should probably just be closed out.

Yeah that seemed to be established a while ago.
Reading is fundamental.
We now understand that the pump is electrically modulated rather than electrically driven. However, if it was electrically driven, I'd expect that the system was monitored via the ECM by a pressure sensor, motor speed and amperage, etc. Very unlikely this would be an open loop system with engine durability at stake.
That might apply even with this mechanically driven pump and that would be a good fail safe mechanism. If the computer detects oil pressure below safe limits it could take action.
