I can almost GUARANTEE that there will be loopholes that the dealer wont tell you about until you are about ready to sign on the dotted line. Example: my dealer (as well as many others) offer "tires for life" which is the biggest crock in the auto industry. I, in not so many words, told the salesman that when I bought mine :-laf. Certainly, they will replace your tires when you wear them out, and believe me, they will need to be really worn, and here is the kicker: As owner of that vehicle, you must do ALL of your maintenance at said dealership. And I do mean everything. And at their recommended intervals. Oil changes, rotations, alignments, inspections, EVERYTHING. They keep the schedule on their computer, mail you appointment times, miss even one, you're done. So lets say that at 50,000 miles it is time for new tires, you may very well have spent upwards of a grand or more on their services, where as you could have told them to go stuff the maintenance in their pipe and smoke it, a grand can buy you one heck of a nice set of tires, alot better than the stockers they will replace them with.
This new warranty is on the same lines as my description above. But add in gear oil, transmission, transfer case oils, ect ect... You get my drift.
Attention: TDR Forum Junkies 
Notice it does't cover the vehicles they sell that get used or have to actually work for a living or that people will actually keep more than the first 5 years. They are counting on the majority of people to trade or resell before the 5 year mark. #@$%!
#@$%!
