The problem with manufacturer warranties goes much deeper than this. In terms of 'fitness for purpose', it's virtually impossible to separate a product from its physical employment. A manufacturer's guarantee that doesn't extend to the installation is of limited value.
Even where the terms of the manufacturer's guarantee appear to offer real protection for the client a problem still remains. In an era of corporate instability it's often impossible to know if the company or contractor providing a guarantee will actually be bound to honour it tomorrow.
A guarantee from a defunct company is no guarantee at all.
Ultimately, much of the blame – should a guarantee prove either unenforceable or null and void – must be laid squarely on the shoulders of clients who blindly accept manufacturers' terms and conditions without question.
