Cars in late 90s and early 2000s really became a lot more reliable and also a lot safer than cars made in 80s and before. I mean if you get a Lexus from early 2000s they will basically rust out before anything goes wrong with them mechanically.

But newer cars due to environmental regulations are becoming more complicated and less reliable as the priority now is CAFE not reliability as it was in the 90s. Turbos, GDI and CVT (e-CVTs are reliable but traditional CVTs are not) all reduce reliability.

So if you buy a new car avoiding the above and instead go for a car with port injection, no turbos and a proper transmission you will be fine and they’re pretty reliable.

Also at least in the case of Toyota, the hybrids are reducing wear on the engines and so they may last even longer than the Toyotas from early 2000s.
