Headers void warranty on engine?

[ROCrMH]

Dealer installed SLP long tube catted headers, SLP loudmouth exhausts and E-force elberbrock supercharger, tune and dyno, and is under warranty. They are a certified GM performance centre with certified GM mechanics. I believed thats the only way they will warranty and stand behind their work, if they do the install.

It seems some dealers are becoming more and more flexible on modifications, especially if you can get them to do the install. The tune is where most dealers draw the line. But as stated above, there are exceptions. I suggest talking with your service dept. and getting anything they say in writing. Feel free to call, PM or email me with questions

Best regards,

Man, this subject has been rehashed a million times.

The headers won't void the warranty, but a tune will IF:

1. You have some kind of warranty issue that involves the powertrain, AND
2. They have to replace a powertrain component

In order for the dealer to get reimbursed from GM corporate for the repairs, any time the service department files a powertrain claim the tech MUST send in a screenshot of the ECM data before GM will approve the claim. If it isn't a stock calibration, warranty is then void.

Dealers tend to use "void" as the easy card to get out of repairs they don't want to do. "Cool" dealers don't do this, however, GM makes the calls on those repairs, period. Please sticky this information.

Local dealers say one thing , but the local dealer is not making the call GM is .

. GM (not the dealer) makes the warranty decision on all powertrain issues for the SS, I just posted the below the other day after a visit to my dealer.

Then we got to talking about the warranty and tuning the SS. The tech told me that whenever warranty work is done on the drive train of an SS, ZL1 or Corvette the tech MUST send the ECM file to GM for review before the warranty claim is approved, no exceptions. I asked about the V6 and he said they do not have to for the V6 (that is not to say they won't), only the SS, ZL1 and Vette.

Anyone confirm this? If they say it won't should I get it in some kinda form of writing.

The New Vehicle Limited Warranty does not cover any damage or failure resulting from modification, alteration or suspected tampering, to the vehicle's original equipment as manufactured or assembled by General Motors.

Any changes to the GM Powertrain, Fuel, or Emission Systems that involve modifications, conversions, or the addition of non-GM approved products will void the GM Powertrain Limited. GM will not be responsible for costs associated with the repair of these vehicles due to failure of the aftermarket installed components or failures of related vehicle systems induced by these non-GM approved products.

Mr. Chevrolet Customer Service Brandon Person - Then I'm a little curious why you won't backup the warranty on an SS that has the installed Heads/Cam kit released in your new COPO magazines. You said in your post just now, and I quote, "... or the addition of non-GM approved products will void the GM Powertrain Limited.", yet the head/cam package is YOUR head/cam package, made by you and marketed/approved for the Camaro SS. With that in mind, if the install is done by one of your certified dealers and your certified mechanics, why is it not backed up?

Basically, if an aftermarket part causes a GM part to fail, then GM is not liable.

As I ask in my post just above yours, then why won't they stand behind the warranty if you install *their* Head/Cam kit for the LS3? That's a GM part. If I install the GM ground effects for the Camaro after I have already bought the car, my bumper-bumper isn't voided. So why does the GM head/cam void the powertrain. Lame.

I don't have the magazine in hand, but I'd bet a lot there is some fine print in there somewhere that mentions voiding the warranty when installing those heads/cam.

There is fine print, that's my point. It's quite obvious too. It's right at the bottom of the page with the head/cam. But if it's their product, for their engine and car, installed by their mechanics, then why the hell would it void the warranty?

Because....you missed the majority of the rest of the statement. Those COPO parts, regardless if they are a GM part or not, did not come on your car from the factory! Therefore, if they cause a failure.....not covered.

I didn't say I don't understand how they are making it legal. Yes, that's their policy, and that's why they are able to do it. I'm essentially getting at that I think it's BS that their stance is that though. I can take my car to the dealer right now and them install the ground effects package. My Bumper-To-Bumper will not be void. I can have them install the short-throw shifter accessory and my power-train (with respect to the transmission) will not be void. I can have them install the GMP exhaust system and Ill still have my power train warranty on the actual exhaust itself (as opposed to installing a Corsa and having the powertrain on everything *except* the exhaust). But if you have them install a GM manufactured and approved engine part, for the Camaro, it voids the warranty.

Their logic is likely this: If you get ground effects, or a shifter, or an exhaust, then you care about aesthetics and sound and show. That doesn't necessarily mean you drive hard so they will keep your warranty. But if you're willing to drop a grand on a head and camshaft then in all likely hood you probably drive the car harder than the average bear so they want to take away the warranty on the inevitably worn out engine/tranny.

As I understand it (and maybe I'm wrong), you can have your dealership install ground effects, a shifter, or an exhaust, or whatever you want on your car, and you're right it will NOT void the entire bumper-to-bumper warranty. BUT....because those parts did not come on your car as "delivered" to you, if those added parts are proven to cause a malfunction or failure, the repair will NOT be covered under warranty. Doesn't matter if the dealership installed them or not. Doesn't matter if the part is made by GM or not. Same with the COPO parts....just because you install them doesn't necessarily mean your entire powertrain warranty is voided. But if they cause a failure....then the repair is not covered under warranty. However (and this is a BIG however), it is the related and probably required "TUNE" to the ECM that will and does in fact void your entire powertrain warranty. So.....in the end, it's once again the tune that has you by the "short-hairs"!!!!

The small print always screws you in the end!!!

the thing is, if you have headers and break an axle, you're going to get your car fixed under warranty, even WITH a tune... GM is not going to step in, until its the engine, I even know of a car that got a transmission replaced, and the car is more modded(and tuned) than my own
