I take it you don't live in the EU? Because regardless of what warranties the seller provides, all consumer electronics generally have a 2 year legal minimum guarantee and the first two blenders you describe definitely would have been covered by it. Bosch would have had to replace that plastic part, not "sell" it to you. I'm not saying this to dunk on Americans. I'm just saying this is a problem that can be addressed with proper consumer protection regulations. Mind you, products will still fail and need to be replaced but this incentivizes manufacturers to aim for 2 years of use rather than 2 months. Of course the real problem is that the broken device becomes your problem once the legal guarantee runs out and electronics waste is just handled in bulk, disregarding the environmental impact and resource waste. All the long-term damage becomes an externality so companies will optimize for limiting the lifetime of components to the least they can get away with because longer lasting products mean fewer sales.
