Agreed! If neither electric nor IC engines existed and we started developing both from scratch today, clearly the electric motors would be reliable within a year (I'm guessing, but probably) and the IC engines would take decades of development and manufacturing maturity to match the reliability.
But, that's not the world where we are. The ICE does have more than a century of development already so Honda/Mazda/Toyota/etc can manufacture an IC engine that'll go 200K+ miles with zero problems, so for a consumer buying a car today, the powerplant is not the source of trouble (whether EV or ICE). It's the rest of the car that needs repairs.
(An ICE engine should not have any explosions occurring, that's pinging and will damage the engine. It needs to be a controlled burn. But I'm nitpicking on the word.)
