Re: Warrant extension
I saw that too and read in it somewhere that for the 15 and 16 vehicles you have to pay additional (was something like $99 EDIT that's to transfer the warranty) and it's am aftermarket insurance, not am actual Jeep warranty. In other words you need to keep paying exhorbidant keep servicing fees for it to be valid. However, since the 2011 changes to consumer law it's not really required anyway.
Another noteworthy point, it does not cover damage due to overheating!
