  1. Planned failure and absurd cost-cutting are the reasons for timing and oil pump drive belts. I miss the days when German engineering was elegantly simple (like the Airhead BMW flat twin motorbike engines or the single cam VW fours which used the same block for carbed, Bosch mechanical and diesel top ends).

  2. Refusal by makers to DESIGN rugged, durable engines is the root cause. Blaming politics on the absurdly stupid designs (like wet or any timing belts on street vehicles) and poor quality choices (like transmission servo pistons made of plastic which stick in their bores which date back a couple of decades) is the root cause. The legal mandates do not and never have forced designers to turn out cheap trash nor their leadership to sign off on cheap trash. If a mode of operation causes undesirable wear that reflects poor choices of material and/or component design. For example lack of old style Toyota quality control costs them millions in failed engines. It is not hard to design rugged systems when empowered to do so, and those choices are internal to automakers. I was alive to enjoy the era of elegant German simplicity in the form of BMW motorbikes whose internals resemble aircraft parts (as they should given BMW history). Those engineers are retired or dead, replaced by whatever design culture wrecked the industry. Complexity that's hostile to maintenance and repair is inexcusable but that's why the used car lot I wrenched for stopped selling German vehicles and sent our trade-ins to salvagers who would part them out, returning to service only invites comebacks as more systems wear beyond economic repair.
