in order to "void" a warranty, the dealership has to be able to prove that the part you installed caused the problem. For example, if you install a cold air intake, and your NAV unit breaks, it should still be covered. However, if you install some aftermarket gears, and your rear end craps out, you may be out of luck. Dealerships vary in what they will and won't cover, too.

I have seen posts here about the oil coming off of the air cleaners and damaging engine sensors that was not covered under warranty. The consesus was people were using to much oil, but it can happen. I have not heard of any one having warranty problems with after market mufflers.

Legally even a CAI can void the warranty. If it's not a C6 part from a Chevy Dealer Parts Dept installed by a Chevy Tech at the Dealer it's not legal. GM has thousands of Atty's, do you?
Your dealer doesn't have the final say on Warranty, the Chevy Regional Rep does.

Only if the defect is caused by the CAI. That is a risk that people are willing to take since so many do it.
