What mods can I do with a warranty?
 

Before I go to the Nissan Dealership service department and ask what mods can I do to my 370z and still keep my warranty? Can I even do a exhaust or CAI without voiding parts of my warranty? Can I install a ATI balancer pulley? I need to know before I go to the Nissan Dealership service department for my first maintenance service? Thank you.

Any non-OEM parts and the systems they affect will no longer be covered.

My Nissan Dealership service department said the only modifications I can do Performance wise is a K&N replacement panel air filter, Nismo cold air intake , Nismo catback exhaust in order to retain my warranty.

That is not correct information.

It depends on many factors, including what you want warranted. I'm assuming that you are worried about an engine failure, which is highly unlikely with the VQ37VHR.

In sum, you shouldn't have a problem with a CBE, but you may have issues with a CAI. If you start adding test pipes and a tune, then all bets are off.

You should be good doing full bolt ons but NO tune. I plan on just swapping my oem parts whenever I need a service. Pulley I wouldn't risk though

The Nissan dealership service department said the only performance modifications I am authorized to do is a cold air intake and they recommend to do the Nismo cold air intake, K&N panel drop in air filter, and a catback exhaust system and they recommended the Nismo catback exhaust. They also said leave the stock catalytic converters alone and don't replace them with high flow catalytic converters or use test pipes. That is ok because once my warranty is over I can modify my 370z as I wish. Engine failure is possible with any vehicle.

Again, that is not correct information. Search around here.

Your dealership is lying to you.

As with most of the questions you have been asking, this has already been discussed in numerous threads.

Op, here's the real breakdown of mods vs. warranty. I didn't want to type this yet again, but there's enough misinformation being spread in your threads that needs to be nipped in the bud. So, here goes:

Your warranty is not determined by your dealer. It is with Nissan North America. With very few exceptions beyond the scope of your questions, your warranty cannot be voided. Period. A warranty claim, however, can be denied. A denied warranty claim does not affect the overall warranty, just that one claim will not be repaired free.

So, here's how mods affect your warranty - A warranty claim can be denied due to mods if the mod or its installation caused the claim. For example, if you install an oil cooler and it somehow pukes your oil all over the road, the warranty claim for a blown motor will be denied. They must be able to draw a straight line from the mod to the failure. That means that, if you install that same oil cooler and your rear diff blows up, the diff will be covered.

So, here's where you have to make a risk analysis - do you feel comfortable modifying a car where an individual warranty claim may be denied due to a mod? The likelihood of a serious failure on a NA Z is low. The vast majority of users here run the standard CAI/TP/CBE/Tune combo, and failures that do not involve owner error or lack of maintenance are rare.

What would I do if I was in your position? I would run the car bone stock for the first 5k or so. Sometimes you get a lemon, and you'll know early enough if you did. No sense in giving the dealer an easy out to deny a legit claim. Once you have enough miles on the car to know you were not sold a defective unit, mod away. This was exactly what I did. Stock for 5k miles, and then very, very far from stock after that. My dealer even installed the mods. And when I had a warranty claim, they smiled, fixed it and handed be a bill for $0.00 since it was not related to the mods.

Well then, what happens if I mod the car and the dealer tells me the claim is denied based on mods but I know they're wrong? I just find another dealer. Believe it or not, mod-friendly dealers do exist. Ask around here in your regional subforum to find if there's on in your area.

I hear an echo on this forum.

I have not seen any disclaimers regarding modding/upgrades to a vehicle and subsequent warranty issues due to aftermarket modifications by any auto manufacturer. I'm not saying they don't exist, I simply haven't seen any.
If a laundry detergent manufacturer places a sticker on the detergent box stating that 'the detergent is not for human internal consumption', then the car manufacturers need to have something in writting as well. Otherwise, a sharp attorney will have a field day.
