Indeed. The fact remains, I shouldn’t have to bring in my legal experts every time I walk into a Jeep dealership because it has some Mopar parts on it.This is sort of off topic, but look into the Magnuson-Moss act. The dealer essentially has to prove your modification caused said issue whether it’s a Mopar part or any other aftermarket part. https://en.m.wikipedia.org/wiki/Magnuson–Moss_Warranty_Act
The moment I have to start demonstrating anything, the whole point of buying “factory approved parts” ceases to make sense.
