The newer car is just more complicated than the older generation one, and sometime this mean one simple sensor that isn't crucial will sour the driving experience. And then newer car software tend to glitch out some time and then refuse to function, requiring patch to fix. This will also happen to EV as well, albeit EV have even less sensor than ICE, not having an engine cut out tons of sensor, thus giving them better reliability.

I have a customer that drive an overcomplicated Mercedes that the water pump will sometime refuse to run, causing the thing overheat. So far no one able to find out what's the issue is, even the specialist. His accord 07 still run well today and he's been refusing to sell it despite having the money to own the latest model.
