I can tell you of an experience I had with a lowly Cabela's Three Forks rod.
The fills (what ever they put in voids in the cheap cork to fill them) in the grip started falling out after several fishing trips over 2-3 years. I mentioned it to a sales rep in the Cabela's fly shop in Owatonna, Minnesota (I live in Missouri and was just passing through). I had the rod in my car, he said "go get it". They replaced it with a brand new rod....no questions asked.....free
