Hey guys,

I just bought a slightly used G37S coupe. Only has 10k miles and has every option besides active steering, I thought it was a good deal.

I have been looking at Stillen Exhausts and Injen intakes and was just wondering what mods will void the warranty? I ran a search but didnt find any specific threads answering this question.

Are intake, exhaust and hi-flo cats the best first mods to do on the G? Cars are always so restricted from the factory I figured this would be a good way to wake it up without screwing with the ECU. I have been looking at the Stillen exhaust because it has a nice sounding tone compared to the competitors and is reasonably priced. Any other suggestions?

Thanks for the feedback and I look forward to hearing from you

 

Most dealers will void the warranty on certain parts in your car only if your mods are found to cause the problem. For example if you put an exhaust on and your speakers fail, your speakers are still under warranty.

 

yeah just like @sskicker said, only mods that can be shown to be the reason for the problem will void that warranty work.

there aren't any mods (not that you will do anyways) that will void the entire warranty. its specific just to the warranty work you are having done if/when there is a problem

 

troof....

Keeping Your Mod's Warranty Intact - For Dummies

 

cliff notes....your stillen exhaust will not damage your car....your warranty is fine. and unless you drive through 4 feet of water your injen will not cause any serious damage either, you will do more damage by running the car hard than putting these parts on (which some people do on oem parts anyway...LOL)

 

what warranty?

 

I understood it to mean the G's warranty, not the mods warranty

 

What I meant was, what warranty on the car? B2B, drivetrain, etc. They are technically separate.

 

Actually, the language is even stronger than that. The dealer is required by law to honor the warranty, cannot void the warranty for using aftermarket parts, and cannot require the use of oem parts.

Unless, like you said, they can show the aftermarket part caused the defect needing warranty repairs. Check the magnuson-moss link above.

But realistically, something like an ECU reflash or replacement might be held responsible for the potential failure a whole lot of parts downstream. But probably not the power seats.

One other thing. Even though the onus is on the dealer to show that your mod caused the failure, it's probably not difficult for them to simply deny a warranty claim and leave it up to you to fight it. Just something to keep in mind.

 

yeah that's what I meant to OP...one mod won't void the warranty (all of the OEM warranties for the different parts) of the car, it can only void the warranty of the part it affected (and even then they have to prove it make it break)

 

Mod all you want, if something goes wrong then replace the stock parts and you don't need to worry

 

the question is, the dealer needs to prove that the aftermarket part caused the failure to whom? to the owner? to a federal judge? how does one get them to prove it? it's not as simple as it sounds. if a dealer wants to deny coverage, be prepared for a long and expensive fight to get them to prove it or to repair the car. in the meantime, you will either be out of pocket for the repair or out of a car, and then there are legal fees etc. the problem is the enforcement mechanism. you can tell the dealer that the intake has nothing to do with the motor locking up, but if they want to deny coverage, the yand nissan can and then YOU need to find a way to get them to prove it to someone. you will be SOL. just look on the various SUbaru forums about the problems subaru is giving people with blwon motors on 08/09 subaru sti's, even those without mods of any kind. that's a $12k motor that they sometimes are and often are not warrantying, even though the motor has suspect build quality from the factory. they go so far as to just claim "abusive driving" to deny coverage. it's not so simple, even though it should be ...

 

there are some good points in that, but Infiniti's aren't Subaru's. If a dealer tried to deny coverage, you can call Consumer Affairs. Most of the time it is easier and cheaper for the dealership to just warranty the part rather than pay legal fees (or penalties if they in fact should have warrantied the part) of their own.

In the end, there is some amount of added wear to the engine by every mod (some are so minute it will never matter, but every mod does wear the engine differently than OEM). If you are ok with that, then mod away. If you are paranoid that something will happen and you don't ever want to risk any problems, don't mod.
