longhauler, it isn't the dealerships call on covering parts under warranty. Chrysler is be very diligent when it comes to warranty issues. Once you put the programmer on it is tracked in the ECM as a flash, and they can see how many times your ECM has been flashed, causing a red flag. From there it depends on the issue, ECM issue your footing the bill. Transmission blown, probably on your dime, unless it is from a truly defective part. Blown head gasket, your bill. As stated above AC stops working Chrysler should cover. That being said, putting HID's could void the warranty if they can show that it caused the power management computer to go out. So you have to be careful on what you do, and as they say you pay to play. With all that being said it is always the manufacturer's burden to prove, but do you want to go to court and admit to violating federal law. Transmission is cheap compared to an EPA fine that would surely follow.
