How do you figure? Most of the warranty? Not even close.

Worst case scenario, if your motor grenades, even if you don't remove the tune before going in for warranty work, the burden of proof is on the manufacturer to prove that any modification caused a failure.

We really outta leave tunes and OEM warranty out of the discussion, but Stage 3 sells a power train warranty for 5* tunes that supplements the factory warranty. I plan to go that route soon as I have almost 5k miles on my truck.

not this again.... read your warranty. it's called a "limited warranty" for a legal reason.

impressive. make sure you log how the engine is performing on that tune its the best protection against catastrophic failure.

No worries I watch timing and the afr is plenty safe.

Dream on. All any dealer has to say is they won't cover it. They don't have to prove anything. Burden of proof to get any dealer to fix it is on the owner of the truck. Remove the tune to hide it? That's no different than cheating and lying.

Um...they have no suspicion of it not being a warranty coverable failure though. So why do you need to prove anything.

RandyinTN

You dont have to prove anything, neither does the dealer.

Dealer walks out to the waiting room and tells you "Ford is not covering this under warranty". The dealer turns and walks away.

Scream all you want. Your only choice is to contact Ford headquarters and or get an attorney. The dealer just goes on with their business and you have the uphill battle of proving them wrong.

Not very familiar with the Magnusson-Moss act, are you?

If the dealer cannot prove something you did directly caused a failure, and it is a 'covered' item under warranty, they HAVE to honor the warranty.

Now, that being said, don't think they can't pull the ECU history and see that modifications were done or altered, even if you flash back to stock.

I am very familiar with the Mag act and see it tossed around as a cure all. The point I am making is a dealer doesn't have to "prove" anything. All the dealer has to say is "NO" and turn around and walk away. The burden of proof is on the owner of the truck.

For example, dealer walks out and tells the owner, "We found evidence of a tune so will not warrant the engine repair". Scream and yell all you want and come back and tell the forum how you got it fixed under warranty. We are not talking about getting a tune and then trying to get a power window switch replaced, etc. Those are no brainer items the dealer will cover. A tune could potentially void the warranty for your engine and drive line.
I owned a 2013 Corvette and within a year installed a super charger and a tune. I knew full well if I had engine, trans, or gear issues it was on me.
