I bought a 2023 toyota rav4 xle which comes with the auto start / stop function. I am actually curious what kind of wear it puts on your car? I assume it wears out your battery faster but what about your engine? I know scotty always says that most of the wear is on start up, but does that happen with this system? Isnt it still pumping oil electrically? Or does that need the engine running? Is it worth trying to figure out how to disable it permanently? Thanks

not a great deal
Isnt it still pumping oil electrically
Oil pumps are critical to the operation of engine. If the pump failed the engine would self destruct soon after. That's why they are mechanical (you do not want to lose oil pressure when you lose power. An electrical system would be too failure prone). So your oil only pumps when the engine is running.
Is it worth trying to figure out how to disable it permanently?
Not if you want to keep your warranty.
Is it worth trying to figure out how to disable it permanently?
You don't need to disable it permanently and end up voiding the warranty. My Civic comes with this and it as a button next to where the drive mode is that I've just become used to turning off every time I start the car. It's become a habit just like buckling my seatbelt.
