This happened to me after about 20 times one it, bout 2 months.. I took it to the store I bought it and GNU replaced it under warranty. It took forever to get it back though, 6 weeks about, I wasn't too happy. Luckily the place I bought it from was cool and let me take a demo Burton T6 whenever I needed it. As long as it doesn't look like you hit a tree or anything, you shouldn't have a problem getting it warrantied.

Denis, this warranty info is straight from GNU Snowboards: "All products made by Mervin Mfg have a one year warranty against manufacturer’s defect. This is provided by us for those products sold through Mervin’s Authorized Dealers only. It covers defects in materials and workmanship. This does not cover normal wear and tear, excessive abuse by riding things other than snow, or impacts due to your steering problems. You must keep your sales receipt when you purchase a Mervin Mfg. product. This is your proof of purchase and you will need to show this if you need to warranty your product. It is good for the original purchaser only and is void if your product is purchased from another person or unauthorized dealer" Take care bro!
