Now a different dealer may not help you out...but the one that contracted the work should.

As far as the OP's problem is concerned, it sounds as if the dealer has done what any dealer would do with a modified item that they had no part in.

Think of it this way...if you went and bought a pair of pants at a department store, took them home and added stitching to them and the material gives way...why should the store cover your modification? That's a simplified example, but it is basically what you are doing to a car when you modify it...changing the specifications or how it operates.

I know I'll get flamed for that last comment, but it IS true about modifications. GM should not have to warranty something that you have modified. I'm not saying cancel the warranty on your power windows for that supercharger you have bolted on...but YES your entire powertrain warranty should be considered gone.

I do hope the OP gets his problem fixed to his satisfaction...but I think it will take him gaining an understanding of how to work with a dealer on a modified item. Dealing with a dealer when you modify is all about building a relationship and an understanding of their expectations. It is definitely a time when you ask first then do versus do then ask for forgiveness. Document your discussions if necessary. Most (and I know not all) dealers are pretty good people to work with. They aren't going to deny your powertrain warranty for a K&N filter (unless GM has told them they have to), but don't think they aren't smart enough to know that those extra oil bosses you've added to your engine probably go to a supercharger you pulled off before you brought the car in for an exploded clutch.

If you walk into a dealership shop and treat the people there with respect, you will usually get the same thing. Sure there are dealers out there to scew you over (we've seen quite a few lately with camaro sales!), but most are just like you and I...trying to make a living.

Excellent advice.
