Diesels, in general, are notoriously unreliable. The only very selective myth I still hear repeated is that diesel engines are more durable now than they were, which isn’t saying much, and skirts around just how much else can and regularly does go wrong with a diesel-powered vehicle. Flywheel clutches are an expensive nightmare, and the vibration destroys manifolds, cams and exhausts in short order. That’s only for the dirtiest diesels that aren’t properly using DPFs or AdBlue (which if you’re seriously considering running school buses in 2022 and not using these, you’re a disgrace). Both of these fail regularly and cost a small fortune to replace. There’s an entire underground industry dedicated to removing the particulate filters from Diesels to improve fuel economy and reliability (because I guess some people just hate kids, who knows?). Electric vehicles have been around for well over a decade now, the data is back on them, and on the whole they are astonishingly reliable compared to the ICE vehicles they are replacing. There’s a lot of cables, sure, but they’re flexible and aren’t inherently moving parts.
