Tuned trucks and Warranty issues

So I know that tuning your truck technically "voids your warranty" yada yada yada

But I am curious to know who has taken their truck in for warranty issues and had issues with their tune, or hasn't, either way.

I just want some real world experiences with tunes and warranty... and which tune you have that this experience is with.

 

I want a tune, want my speedo re-calibrated, just want to hear what you all experiences yall have had.

 

Thanks!

I've been tuned for over a year, love it.

 

I've had my truck in for the free oil changes and all the recalls. Never have they said anything about my truck being tuned or modified.

 

The question you're asking is pretty loaded though, as it will really depend on what goes wrong, how heavily you are modified you are, and your relationship with your dealership.

 

With my g8, I had an outstanding relationship with the dealership. I had it cam'd, tuned, and fully bolted on. I had some wheel bearing issues and transmission issues, which they very well could have said sorry you're too modified to cover, but they were cool and covered everything under the 100k powertrain warranty.

Oh I know it's loaded. But that's why i didn't specify.
I want it all. And I'm sure there are loads of people that would like to see the same thing.
I know that is one of the questions I have seen the most in my research I've done on tunes.

I've had hand held tunes on everything I could get one for. Iv had one warranty claim transmission on my trailblazer ss. Had a diablosport on it they knew it no issues. Of course that was ten years ago.

Most likely the only time your going to have a issue is if you have a major failure while having a aftermarket tune and GM requires the dealer to send in a snapshot for approval.

 

 

 

  • Be advised that GM REQUIRES retrieving the Calibration Information and performing the Calibration Verification Procedure as outlined in this Bulletin, whenever diagnostics determine a hard part failure may have occurred on internal engine parts and BEFORE disassembly, repair or replacement of an engine assembly under warranty.
  • Be advised that GM strongly recommends retrieving the Calibration Information and performing the Calibration Verification Procedure as outlined in this Bulletin, whenever diagnostics determine a hard part failure may have occurred on transmission, transfer case or rear axle components and before disassembly, repair or replacement of a transmission, transfer case or rear axle assembly under warranty. It is also recommended that the ECM Calibration Verification Procedure be performed whenever diagnostics determine that catalytic converter replacement is necessary.
  • It is not a requirement to verify transmission control module calibrations on gasoline engine applications.

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

That's basically it^

 

You still have a warranty, until you ruin something expensive, because looking at your ECU is actually part of the repair process and not a decision made by the dealer.

 

While it's perfectly reasonable by GM, it does suck they don't offer a solution for those who just want their truck to have the equivalent of a "sport" mode

Its totally reasonable.

and what I figured. Just looking for real world experience from people, not only for me, but for those others looking to get a tune.

There is not much evidence of what happens in the real world since it's

-only with 2014+ ecu's (except diesels) that a tune can't be hidden, there's just not many people who have blown their engines or transmissions yet

-nobody wants to admit they blew up their motor/tranny and had to pay for it

-certainly nobody wants to admit they had it tuned, they took measures to hide it, then they "scammed" GM

The thing that bothers me the most, is that if you have a good tuner, it's highly unlikely it's going to cause a problem. It may even be better for the transmission than the stock tuning. Like it's a smart thing to do in that regard.

 

Butttt, I can't get over the risk of, what if my transmission is screwed anyway and it's going out whether it's tuned or not tuned.

 

What if carbon buildup causes a significant problem with the engine at 85k miles.

 

It's not like an LS motor where blocks, internals, heads, and transmissions are a dime a dozen. This stuff is expensive.

EXACTLY!!!!!

 

Couldn't have said it better myself.

 

I know a lot of the 5.3L engines have lasted a ridiculously long time. But that warranty is there for a reason. So I know that I have been curious as to whether or not mine is one that is going to just blow up on me before the 100k miles.

My other truck lasted a long time and had absolutely no issues. but theres no guarantee this one will unfortunately.

Well said.

 

With that said, mechanical failures happen, shit happens. Tuned or not. You're rolling the dice tuning (the saying "you have to pay to play" comes to mind). I like to roll the dice, as I trust my tuner, and I have a family member who is a mechanic (not for GM) that can help me out if something major does go wrong.

 

I don't want to buy a vehicle and suffer for 100k knowing how much better it could be with a tune and modifications.

On the flip side to that

 

It's been said that these 5.3's and 6.2's have hardly anything similar in regards to the old ones.

 

They are completely new engines from scratch, and the only thing really in common is the displacement because there was no need to change it (and I'm sure it saved on tooling costs)

 

That also scares me lol, there's no history on them, just vast number of them on the road
