Gradual failure?  Either it fails (partially or wholly) or it does not.  If=
 you start getting numerous products failing within the warranty period the=
n you get a bad rep and the company selling them get a bad rep, not to ment=
ion costing the company money.  The more you sell, the worse it gets.

Either design it properly and test it thoroughly, or don't bother.  Arguing=
 against the opinions and advice of dozens of engineers that have vastly mo=
re experience than you is not going to help you when you are sitting in a p=
ile of burnt out products and an empty bank account because no-one else wil=
l touch a design you have made.
