Leaking radiator on 2014 jku

Noticed my radiator starting to drip on the crimp and debating having it warranties since it has 18,000 miles or replacing it with a mishimoto aluminum radiator to get away from the plastic oem. Anyone done this, any suggestions or waste of money? It's suppose to have alot more cooling capacity.

Unless you live in a really hot (Sahara desert) type environment or do a lot of low range, high rpm running get it fixed for free.... Just my 0.02
