Will A Tune Void My Warranty?

[jrpimp00]

This is the reason I have my T/A. I can understand GM not warranting any car that's been tuned. Just like Samsung wont warranty a laptop that's been opened. Or a phone that's been rooted.

That is an excellent comparison.

I have a tune and my rear end was replaced under warranty.

I have a tune, headers, intake, tb, HF cats, and my rear end clunking noise could not be fixed by changing the fluid/friction modifier.

When the dealer decided they wanted to open up the rear end, they had to send the file to GM containing a snapshot or w/e of ecu. GM gave them the go ahead, even with my tune, and they replaced the ENTIRE rear end. Total would have been $1,750 and I got a new rear end with the rest of the car at 25k miles.

So dont give up hope if you think your mods or tune actually didnt cause the damage.

It wouldn't matter, to them its 1's and 0's. They aren't going to start dissecting what the tune did, just that it was done. It's not open for interpretation from gm's point of view.

Nice write up chase. This is exactly why I'm looking at the kooks lt's with green cats and no tune. I don't mind voiding my exhaust warranty, but don't want to void entire powertrain for the time being.

Absolutely. Like I said in the opening post the Magnuson-Moss Warranty Act (15 U.S.C. 2302(C)) still applies. They can not deny a warranty repair unless the issue in question is the direct result of the tune.

Thanks.

Has anyone looked into buying an additional ECM and tuning it is a good work around? Id think that switching that out would work.

Doesn't work.

There are too many variables that are synced between the ECM, BCM, and PCM. Once GM pulls the ECM they'll see none of the variables line up.

That and you'll be hard pressed finding a dealer that'll program a second ECM to your VIN

My dealer actually told me to do this. Mod friendly. They told me they would make sure all the numbers matched if I proceeded with a dyno tune and long tube headers for my car. The dealership stated they have done this on all the camaros in their performance department. If anything goes wrong with the car they will swap the computer with the stock one thats been untouched.

I'm willing to bet that GM won't care what they "told" you. They'll still void your powertrain warranty.

That dealer is committing fraud. Good luck with that.

I would be leery of doing it even if the dealer told you to and that they would help. If push came to shove I doubt they would admit involvement. Sometime you just have to pay to play.

I've thought about a spare ECU/PCM whatever you call it.

But then there is OnStar...
