A couple things - I'm not talking aftermarket warranties as some of you are referring to. I'm talking a warranty that is backed by Chrysler/Mopar so you just go into their dealerships for repairs. The 3rd party warranties are super risky as the companies can just quietly go under, keeping your money and leaving you high and dry.
Also, if not the lifetime warranty, even extending the factory bumper to bumper up to 100K is appealing. I agree with what people are pointing out that repairs these days are expensive. Cars are becoming almost as much computer as mechanical and repairs can be complex and expensive. I use to work on all my own cars are replace clutches, starters, transmissions, etc. but I wouldn't know where to even start these days.
And another thing worth mentioning is at the time of purchase it doesn't make sense to buy the extended warranty at the dealership. Even if you want to, go back and buy it at the end of the bumper to bumper. Otherwise, you're effectively giving the dealership an interest free loan for 3 years (and likely paying more than you should for the warranty, too). I'm going to shop around and see how I feel over the next couple years, and possibly buy an extended near the end of my 36K.
On Edit: In doing some research you may have to buy within 1yr/12K miles of original purchase. In any case you're still better off waiting as you'll likely find a better deal and don't have to give them your money for a year
