Anyone with a tune have warranty work yet?

With some questions about a tune voiding warranty lately I'm curious if anyone that has had a tune on their Camaro has had any warranty work done. If so, did the tune cause any warranty questions?

well my warranty is up now anyway but i had a tune on my 05 SSS since 06 and they never discovered it or voided any warranty work.

I did buy a blank pcm for tuning purposes and everytime i would bring it in, i swapped it out with the stock one.

The new ECMs can tell how many times they've been flashed and can lead to the dealer investigating it further. The people that say they are keeping a spare ECM around haven't thought through what I'd call a "catastrophic" failure. In this scenario of powertrain failure, it will be really hard to just throw the new ECM in and get believable data into it before you take it to the dealer.

These days, a powertrain failure WILL get a regional rep involved and they will care whether you have "tuned" your car. Its a new GM and they pay quite a bit more attention to big warranty payouts.

Thanks for a very clear answer on this, I am a total newbie to doing anything to a stock engine/drivetrain, but as I was reading all of the posts on tuning it sounded like an inexpensive way to get better performance from even an engine with all stock parts (no changes). After your post it does not sound worth the warranty risk unless I plan to add after-market parts.

That leads me to one question, if I get GM certified performance parts that would require a change in the tuning config, would GM do the tune and keep the warranty intact? (I would be looking at GM to install also)

Sorry in advance for the newbie question in this section but this seems to be the section where the experts are...

Identifying Aftermarket Non-GM Calibrations
By Blog Admin on February 1, 2009 7:17 PM | No Comments

For more details, refer to bulletins 08-06-04-033 (Gasoline Engines) and 08-06-04-006A (Diesel Engines).

General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non GM - aftermarket engine and transmission control calibrations being used.

When alteration to the GM released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine, transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy to cancel any remaining warranty coverage to the powertrain and driveline components, whenever the presence of a non-GM / aftermarket calibration is confirmed -- even if the non-GM control module calibration is subsequently removed.

Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That's because GM testing and validation matches the calibration to a host of criteria that are essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different than those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life.

Additionally; non-GM-issued aftermarket engine control modifications often do not meet the same emissions performance standards as GM-issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and / or penalties.

GM service bulletins 08-06-04-033 and 08-06-04-006 outline procedures to identify the presence of non-GM / aftermarket calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated.

In February 2009, PQC will begin piloting a process to confirm the ECM calibration is GM-issued. Beginning in February, PQC will require a picture of the engine calibration verification screen, as outlined in the bulletin, before authorizing any V8 engine replacement (both Gas and Diesel). (fig. 19)

If a non-GM calibration is detected by the dealership, follow the procedures outlined in the bulletin. Once documentation of the non-GM calibration has been received, and verification has taken place through GM, the remaining powertrain and driveline warranty will be cancelled and noted in VISS, and the dealership will receive the following notification:

Based on information that has been received, please inform the customer that the Powertrain portion of the New Vehicle Warranty is no longer in effect for the engine, transmission, driveline and rear axle on VIN XXXXXXXXXXXXXXXXX, due to the presence of non-GM calibrations and / or equipment. The stresses resulting from the non-GM calibrations and / or equipment were not validated by GM and therefore cannot be warranted on any components that are subject to those stresses. Repairs to powertrain or driveline components that may currently require repair should not be covered under the terms of the new vehicle warranty. The warranty group has been advised of this information and VISS will be updated accordingly.

- Thanks to Jay Dankovich

It doesn't say they check anything to see if it was previously tuned and then set back to factory standards...

They must not have had at the time or just not looked at the odometer match from the IP to the ECU.

So if you dyno tune an l99 and get 15hp from it...gm is saying the motor isnt tested with that extra stress of still making less hp than a stock ls3? B.S. Maybe a tranny tune, but tunning a stock motor professionally will never hurt it and GM would have a hard time proving that a proper a/f ratio caused a motor to gernade.

If you are worried about voiding a warranty, DON"T do anything to it, plain and simple!! Just know if something breaks after you make modifications GM may or may not warranty the broken parts. If you choose to modify anything just assume that portion of your warranty will be voided.

yes, but a tune and a CAI have nothing to do with a keyfob not working.

the issue is if/when a change to GM's programming is done and engine/trans damage occurs.

Why is everyone so worried about warranty work? Has anyone actually ever broken a bone stock lsx motor? Transmission besides the recall for the new manuals? There are thousands of people modding new cars every day and it seems like most of the worry warts are here. Are vette forums like this? Mitsubishi? Seriously I dont know. But man some of you guys worry too much. The best way to keep your warranty is to not touch your car ever.

Curious, if a "tune" is just reprogramming a few codes on the computer, why are some of these performance shops charging $500 to do it, and calling that a deal? I would think if you are just changing some codes, it should take 30 minutes and call it a day. Am I missing something here?

Yeah, it's the same reason headers cost twice what they used to...people are willing to pay more so now they cost more. To make it worse most people think the most expensive product is better than the an exact equal for half the price., just look at designer clothing. Same with tuning, it really shouldn't be more than $300 but the big name shops are selling you the same thing because the name is behind it.
