So if you look through almost any thread on here that has to do with aftermarket parts, someone is asking how it will impact their warranty. Thought I would provide a little backround from what I have seen as a tech at a Chevy/Buick dealer.
Here is the "by the book" definition of what is covered (thanks sx) http://api.viglink.com/api/click?fo...ge periods.&jsonp=vglnk_jsonp_138488678707210
When your car goes to the dealership for a repair, it makes a big difference to the technician working on your car whether the repair is covered under warranty or not. A tech is paid flat rate, which means that he or she gets paid based on a set time for each job. These times vary if the car is under warranty or not. For example (these times are not exact), say a rear main seal is leaking. If a customer is paying for the repair, the flat rate time is 8 hours. So the tech gets paid his hourly rate times 8 hours. The same repair on the same vehicle, if still under warranty, may only pay 5 hours. So it benefits the tech if the repair is not covered by the warranty.
This doesn't mean that they will look for any way possible to not get it covered by the warranty, but if there is something obviously changed on the car that may have caused the fault, you bet your ass that they will bring it to the manager or writer's attention in order to make the most money possible. That being said, it has to directly relate to the fault. For example, say you have a sway bar link making noise. Just because you may have a tune or exhaust does not mean that the link will not be covered (Google Magnuson/Moss act). The links are no way affected by the tune or exhaust, therefore they will be covered. Now say that you installed an aftermarket exhaust, and now you have something rattling against the muffler. Obviously this rattle will not be covered, because it was caused by something you changed, not something installed at the factory. The only way it would be covered would be if the exhaust was purchased and installed at the dealer.
Now thats not to say there is no way around this. Say you blow a speaker and have an aftermarket headunit installed. The speaker will not be covered because of the aftermarket radio. Swap the factory one back in, drive to the dealer, and get the speaker fixed.
It also doesn't hurt to ask. When the brakes started pulsating on my wife's Malibu at 25k, I called my local dealer and asked the service writer if the repair would be covered. She informed me that as long as the brake pads were not severely worn, then the repair would be covered. Don't forget, you do not have to go to your selling dealer. If they are giving you a hard time about covered repairs, go somewhere else. You can go to ANY GM dealership to get warranty repair.Some repairs are up to the service managers discretion. If you are a good customer, they can "goodwill" repairs that may not be covered because your warranty period is up. I actually saw my service manager warranty an engine at 55k (truck had 3yr 36k powertrain warranty) because it was owned by a large company that had all of their trucks regularly serviced with us. I also watched the same sevice manager deny a warranty repair on an expensive PCM replacement, because the vehicle was over its warranty period by 3 weeks, and the customer was a giant pain in the ass.
Hope this clears up some confusion. As a general rule, if you are that concerned about a part voiding part of your warranty, don't install it. Any time you are modifying your vehicle, you take some risk. Do your research, use only high quality parts from reliable, reputable companies, and be nice to the people fixing your vehicles.
