Has anyone ACTUALLY had a warranty denied due to tuning???
 

All this talk about voiding your factory warranty if you tune. I admit, I'm tempted to tune, but scared about losing my powertrain warranty too.

Is there 1 single person out there that has actually had ANY type of warranty repair denied because their have TUNED their car???

this should be good.

crickets...:emoticon2:

WAIT JUST A DAMN MINUTE!

Why don't you preface the question with something about trying to warranty a blown engine or transmission.

GM is not interested in whether or not you tune your car UNLESS you're trying to utilize your powertrain warranty for a major failure. So, the only people who should be answering the question posted here should be people who have grenaded an engine or transmission, because those are the only scenarios that GM is going to take the time to check for a tune.

The whole mantra of "I want to flash it back to stock when I take it to the dealer for a dome light warranty!" is ridiculous. It just shows how much misinformation gets spread through the internet.

If you tune it won't void the window motors or dome light just the powertrain.
I specifically asked a question to some GM folks I know about the tranny. Since mine was an earlier Vin and some of those had problems with the tailshaft breaking, I asked if my tranny broke would it be covered even if I had my car modded a little, especially when GM knew that some had problems.

My answer was. " Highly Unilkely that they would cover the tranny on a modded car" Hopefully I never have to find out>

I love how you started this :clap: .... good info!

Im curious on who will chime in on this topic :popcorn:

I don't think the OP needs to preface his question with anything. He asked a straight forward, clear and concise question....Has anyone been denied any warranty work based on the fact that their vehicle had been tuned. It's not an ambiguous or a "trick" question. There are scenarios shy of grenading an engine or transmission that are still very expensive to correct at $100 per hour shop labor such as a leaking head gasket or a whining rear end etc. In theory, could not these examples be denied due to tuning?

They are classified as powertrain failures. The question only applies to people with powertrain failures, because that's the only case where GM will check for a tune. It skews the results horribly to include people who have a tune and go in to get a window switch fixed. Technically they could have a tune and still get "warranty work" completed, even though it doesn't even apply.

The OP did not solicit stories regarding people's experiences getting non powertrain problems fixed under warranty despite "being tuned". He specifically asked for DENIED experiences based on "being tuned".

Good,direct question. I personally know of no one that has been denied. That includes a few that had lifter failures. It's tiring hearing people complain about the warrenties and tuning. GM has to prove the tuning caused the failure.

If you do have the car tuned just make sure it's done by a preffesional that knows what they are doing.Just like there are alot of good tuners, there are a ton of bad one's too.

Right, but the only time a tune would apply is in the case of a powertrain failure. People are going to sit here and assume that since nobody's responding, that having a tune doesn't cause a problem... However, the inherent flaw is that the number of powertrain failures is probably EXTREMELY low, meaning the sample set barely exists. The way the OP phrased it is not going to result in usable answers, since nobody's going to get anything denied for a tune other than a powertrain failure. This means all the people with a tune that go in to get something petty fixed will probably respond saying, "Oh, I got this fixed and have a tune!" and it's going to make people think they too can get away with it, even if they put a rod through the side of the block.

I'm trying to prevent people from getting a false sense of security about putting a tune in their car. FYI, I worked as a powertrain engineer for one of the big three... and warranty analysis was 50% of my day-to-day job. ;)

No, they don't (to the bolded part). Read your warranty terms. ;)
