Hi, if 4c is tuned, is warranty void? If you put back to stock, is warranty valid. Can you detect over revs on tuned system. If put back to stock, can this be detected. What about new intake and spacers, is warranty still ok if 4c has these installed. Thanks all.

In Oz any engine related problem would see your warranty voided if you had a tune. Unsure in the States.
The exception here is that one Sydney dealer became a Pogea distributor and they said they would cover any warranty work with Pogea mods fitted.

In the US you have protection that the rest of the world does not. Magnuson Moss Warranties Act puts the onus of proof that a failure was caused by the modification squarely on the manufacturer. That said, it would need to be civilly enforced - you’d have to pay a lawyer to sue FCA if it were denied. Would start to add up to a lot more than most repair costs in no time. Especially if there is a chance of losing!

Can a tune be detected if the car is returned to stock? Some people here, including a tuner, have indicated that swapping the ECU leaves a trace in other computers in the car. Certainly, a custom tune where the ECU gets cracked, will leave evidence.

There are always warnings on forums about spacers causing wheel bearing issues. There does not seem to be evidence to support that. If you had a failure, then you either did something very wrong, or your bearing was going to fail anyway.

If your dash de-laminates or your heater dies, it will hardly be on account of a tune or spacers.

But if you tune allows you to over-rev the engine and you cause damage, then return the car to stock to claim warranty, I personally hope that they can figure it out and deny your claim. That’s just dishonest, and costs the rest of us. Man up in that case, is my opinion,

Dealers can easily identify when you swap back in a stock ECU. On other cars, I've seen this done with starter counts not matching up between the ECU, the car, and the mileage. Of course, that's after they check the basics like checksums and fault logging. "Undetectable" is tuning marketing nonsense. Some makes won't even diagnose an engine if there's evidence of a tune.

Makes like Porsche, literally have a "SWAT team" of techs that look at this stuff when a dealer reports an unusual expensive failure for a warranty claim. Mercedes Benz flags cars that it spots on social media, and forums, and uses that information to flag cars to be denied warranty claims.

If you can't afford the ramifications of a tune/modification breaking the engine and/or drivetrain, don't expect a warranty claim to save you. Manufacturers are used to dealing with fraudulent warranty claim nonsense. With counsel on staff, it costs them nothing to fight it. The angry legal letter that you have your paid attorney or friend attorney write isn't going to scare them. It will get a response establishing that the car was modified and that you/ the owner's assertion, that the car was stock, is fraudulent. Warranty claim denied.

If you made modifications, be honest with your dealer. They may work with you and advocate for the claim. A posture of the car being stock, when it can be proven that it's not, is going to get you into trouble.
