I suggest an experiment.
Go buy a stock WRX, drive it like they do in the ad, then 6 months later take your busted up car back to the dealership for warranty.
Or even better, buy a can of Lynx, spray on and try to pick up, then fail miserably . Send can back to the manufacturer.
It will be funny for everyone. Advertising and real life are two different things IN EVERY MARKET.
That said the bike industry is actually incredibly good with warranties. I broke a downhill frame from a company starting with N, took it back to a bike shop with two words starting with B and A. 3 weeks later Ta da! new swingarm on a year old frame. It had been raced and ridden hard, but was the appropriate bike for that purpose and i wasn't an ass about the replacement.
Stuff breaks when you jump on top of it from a reasonably large height repeatedly, even aluminum push bikes. I would've thought that would be fairly obvious.
