I have a situation. I bought my 2012 and bought the life time warranty from Chrysler. My dealer is pretty good but now that I have replaced half of the Jeep with aftermarket the only thing the warranty will be good on is the engine/transmissions. That was my main concern but asking my dealer they said they look at every claim as a case by case basis and if mods affect it is up in the air. They aren't saying yes, they aren't saying no. I know they can't really guarantee anything but it sounds like a politician telling me to keep the warranty. I'm thinking it may be smarter to cancel the extended warranty and get my $ back on it which is state law that I can do... What does everyone else think? I do off road and they are aware of it I'm not going to try to lie to my dealer.
