Ok, It seems I can't get a straight answer here. I would like to know if doing some of these modifications will affect the warrenty Z-Tube, Groundwires, K&N filters etc.... Will this stuff affect the warrenty on the car?

 

warrAnty... z-tube and k&n will definitely NOT affect the warranty, but ground wires might...

it all depends on which dealership you go to!

 

Well, the answer is... it depends.

There is a law called the Manguson Moss Warranty act. It basically says that if the aftermarket part doesn't directly cause the problem, it can't affect the warranty. So, if you put an a Cold Air Intake, they can't void the warranty on the stereo - there is no way one impacts the other. It also says the burden of proof is on the dealer.

However, real life can be different. The dealer can make it very difficult, and it can be hard to force the issue.

Some dealers are much more mod friendly than others, it's a good idea to talk to your service advisor to try to see how they will react.

 

If oil from the K&N filter fried the MAF sensor, that would not be covered. But that's the only thing that outright stands out to me.

Here's Infiniti's anwer, from the web site.

"If you install non–Infiniti after-market products on your Infiniti vehicle, you assume the risk that if you later present your vehicle for a warranty repair, the claim will be denied if the repair is determined to be necessary due to the non–Infiniti part/accessory or its installation."

 

The dealer must prove that any aftermarket parts have caused any problems your car may experience. Without this proof, they are obligated to honor the warranty.

 

If driveability issues arise because of the installation of the Z-tube due to changes in air flow and erroneous MAF readings (unlikely) then potentially, they could charge you for the service to address same.

The K&N, if over-oiled, could definitely foul the MAF sensor and cause non-warranty issues.

Grounding systems could potentially be an issue as well with some dealerships, especially if improperly designed or installed. I supply many new car dealerships (Nissan/Infiniti, Honda/Acura, Mazda, VW/Audi, Subaru, etc.)with GroundingGear™ Systems that are sold through their parts departments, and installed by their techs. I'm told that it will not affect their warranties and has been confirmed with the companies. However, this may not be true in all cases, nor with all grounding kits.

A few dealerships even sell GroundingGear™ Equipped cars off their showroom floors including a limited GroundingGear™ Edition MazdaSpeed Miata that is fully covered under warranty.

 

Thanks for the help guys, looks like Iam just going to get z-tube and K&N filters

 

The warranty is not with the dealer, they can do nothing. Someone pays them if Nissan won't then you pay -------that simple. Don't confuse the act of selling you a car with the Service Department they are two entirely different profit centers.

People get the "Agency" legal term relationship mixed up.

Dealers have a list of what Infiniti pays for, if they exceed certain bounds they get stuck with the check or charged back in future.

If the dealer refuses to cover, it is because they know [from experience] what Infiniti will say. Then up to you to persuade Infinti zone officals to accept the bill.......that simple.

Warrantied parts are returned to Infiniti for analysis, if 4 months later a part was found to be owner abused [MAF for example] the dealer gets charged back the warranty claim.
So they are reluctant to try to warranty obvious owner abuse.

Service managers have a slush fund to cover goodwill but it is a tiny amount based on number of cars sold at that dealership. Who that goes to is a function of how you stand with Service manager [his mother and father come first then employee relatives, friennds of Owner and GM.......then customers who spend alot of their own money on services or gave a lot of profit in buying the car, then everyone else.

Not knowing how things work is a sure wayy to not get optimum.
