For example, if you had a true CAI that took air from outside the engine bay and you sucked up a bunch of water because you went into a huge puddle, the dealership will void your warranty based on the CAI being responsible for doing the damage.
Can't the dealership just say, "Well, the CAI contributed to the problem you are having, and so, we cannot honor the repair under warranty."
Your word against the dealer. Sue them. It'll cost you more than the warranty, that's for sure.
It's a no win for the consumer. Mopar dealerships would likely want you to keep your warranty so that they will get paid from Mopar/Fiat/Diamler whoever the heck owns mopar these days, for the repair work. Most dealership work (at least according to my father-in-law who worked at a Ford dealership for better than 20 years) is warranty work. They do count on it greatly.
