SO does anyone know what i can do to my car that will not void my warranty? I have heard of telling the dealer about certain mods and as long as you let them put them on then its ok. I just want to know how i can make my car faster because stock just sucks. Thanks

you can buy the stage 2 kit when it comes out, gmpp manifold and exhaust

Yeah i though as long as the dealer installed the parts they will cover the parts under the warrantee.

Otherwise the Magnuson-Moss warranty acts strictly forbids an auto manufacturer/dealer from voiding a manufacturer's warranty just because you put after-market parts on your vehicle. Those specific parts aren't warrantied by the manufacturer and if those parts cause your vehicle to fail in any way the warranty work can be denied. It's on the dealer to prove that your parts caused the vehicle to fail. And unless you're running a big turbo and the engine blows, good luck to them.

So are you saying that i can put after-market parts on my car but the catch is that those part are not covered? And as long as the parts do not cause my vehicle to fail then i should be alright? One Last Question-Can i put aftermarket exterior parts on my car?

Basically, yes to both questions. To be absolutely sure go to the dealership and talk to the service manager and let him know what you want to do. He is the driving force behind what is covered and how strict the 'rules' are followed. 9 times out of 10 they are more than willing to cover whats been done. Sometimes they will even install the parts for you.
If there is a habitual use of warranty due to misuse, then they'll hammer you and your repairs will have to be paid out of pocket (yours).

Not trying to piss on your parade but after having worked at GM dealers for 16+ years, i had to laugh. Because thats what the service manager will do if you bring up the MAg-Moss issue ;) I guarantee they will blame it on your mods no matter what!
Best advice, i agree with your latter statement, talk to your local dealer and see how far you can go w/o voiding the warr.

and if they want to be a bitch about it.. that's when us that work in marketing start a pr campaign like they've never seen before. ;) not that i'm worried about it cause my dealer is cool.. but god forbid they were to ever be jerks about something like that to me because it would end up costing them alot of business in my small town :)

i could see it blasted all over my local websites, a billboard, and scrolling marquee at our racetrack... "thinking about buying a chevy from xxx, think again. They do not like to honor federal warranty regulations. see mywebsite.com or call 1-866-xxx-xxxx for full story"

screw the warranty a true enthusiest doesnt care about things like that make the car what you want it to be if something breaks becuase of what you did fix it

So if I want to mod my car, but can't afford to fix it if something catastrophic happens, I'm not a true enthusiast because I'm counting on my warranty to fix it? I would love to mod the hell outta my car, but some people have to worry about what the risks of mods are, and which ones a particular dealer will fix and which they won't. That has nothing to do with how much of an enthusiast I am, but more to do with how much spare cash I have to dump into the car.

well its not that but if you do the modifications the right way and those dont cause any problems then the dealer has to honor the warranty for something that breaks if it isnt related to the mod, i just get so sick of everyone being so worried about losing their warranty it takes the fun out of modding

I work in insurance and I guarantee you there will be no laughing at me if a warranty issue comes up that isn't obviously related to a mod I've done. Thankfully the moss act puts the liability on the dealer to prove the defect was caused by an aftermarket part. I'm glad I didn't go to your dealership for service as someone would have left with an impact gun and air hose trailing them (and I'm pretty sure it wouldn't be me :D)

My insurance company is my problem to why I can't modify my car. They said big rims ok. But lower the car about an inch and they would not cover me. :( B*tches! Either way I am going to put some sportlines on it w/ my Konigs. Should be pretty hot. Luckily you guys don't have to worry about most mods becuase of the moss part of the warranty. The base models do. Besides, unless you are throwing a huge shot of Nitrous then I don't see how you could void your warranty. Chevy already took care of the hard part (the supercharger).

Thanks guys for all the help. I am still going to aftermarket the hell out of my car but i wanted to know.

Welcome to the world of the SRT and factory upgrades.

I doubt most dealerships will honor a warrenty even if they install the parts. Unless you have it on paper it doesnt mean shit. Some dealerships are ok. They understand that your air intake did not cause your motor mounts to snap but many will not honor work done on it regardless of who installed it.

The moss/mag act is a joke. Yes, it is on them to come up with proof that this did that but they also have time, money, and lawyers on their side.

Example: You break something and take car to dealership. they say no, your air freshner caused it. You say bullshit, moss/mag act. They say ok. So what. You now have a broken car. You have no way to work/school. Even if you do you are still going to have to retain a lawyer ($1000-25000 is normal), miss work/school for court, await judgement plus a ton of other leg work and money spent. Most of us do not have that time or money sitting around. they do.


Final answer is you have to pay to play.

i have no clue what u are talking about, i didnt say anything about my dealer

That was to FastFossil sorry.

Well Down In Miami The Dealership I Got To Is Pretty Cool....on My Test Drive The Salesman Him Sle F Was Ripping The Hell Out Of The Car..he Himself Told Me About Taking Off The By-pass Valve..but Anyways If U Mention The Moss Act Most Dealers Dont Even Wanna Waiste Their Time Or Money On Something That Wont Cost Half As Much As Lawyer And Courts And Everything Else So I Personally Think If Ur Cool And Honest About Wut Ur Oding To Ur Service Manager They Will Take Care Of You

My dealer fixed things on my car with my mods under warranty UNTIL I hit 36K (actually 36219 to be specific), then it all changed. Even when it was the same problem I reported BEFORE my 36K. They told DCX that I had my car set up for racing :eek:
Guess they have never seen a car REALLY set up for racing if they thought mine was but whatever.
Some dealer are more liberal when it comes to mods, others are more strict. Yes the MM Act says they have to 'prove' it, but what does it take to prove it I wonder? An engineering diagram of why it (the part) failed, or a simple 'Because I said so.". I think I saw in the MM Act that it has to be in writing, but again, is "because I said so" in writing good enough to qualify as proof?
I actually contact DCX Customer Service & got them to say in writing that adding a part doesn't void the entire warranty, just the part you installed & any parts it might effect. (When I told my Service adviser that, he shut up.) Adding a new pulley will not void the warranty on the radio for example, but might on the AC (or whatever else the pulley effects).
As far as insurance goes, mine allowed me to put a $ figure for extra parts on my car so incase somethign happened to it, I can get up to $X back to help replace the upgraded parts.
