Similarly, long warranties encourage misuse and neglect. This also brings up the total cost of each vehicle built, as the mfr has to cover neglected-but-unproven claims. So, if you want the price on Mazda5s to climb, clamour for a longer warranty.
I always felt that problems in the 1st 3-5 years are the mfr's fault, but most of the problems after that are the owner's fault.
