    My guess is the thermodynamics of a hot engine makes the rubber and plastic parts fail more quickly than they would otherwise.

      Not really. There’s no excessive heat outside of the engine bay, but plenty of rubber and plastic. Heck, even my rubber grip on my toothbrush has turned into a mush after some years and it wasn’t even exposed to sunlight, as there are no windows in the bathroom. Organic matter decays, it’s just life.

        The engine compartment is what I was addressing. There’s a number of gaskets where failure can destroy an engine etc vastly reducing the life span of the car. Like while it does matter if the tail lights go out you can often reroute a cable for something like that with little difficulty. You cannot reroute the critical degrading components in a combustion engine as easily.

        Electric cars are estimated to have 2/3 the maintenance costs of ICE vehicles. Their lifespan is likely only limited by the frame whereas ICE is limited by the frame and the engine. Major fail points of older cars include timing belts and head gaskets.
