Dealership Warranty

[Fishmiser]

This happens all the time. A common one is when dealerships install a lift, oversized wheels and other aftermarket parts on a new truck, they include the "free" warranty and sell it for a hefty markup. When the truck breaks, the owner finds out that the mods broke the truck and neither the OEM or "free" warranty covers it. People rightly get pissed because you'd think everything was kosher if you buy it brand new that way.

"Free warranty" and mods are mutually exclusive. It's not a big deal though, your OEM warranty coverage will probably be in effect with approved Nismo mods, but the mods definitely give the "free" warranty an excuse to outright cancel you.

I'm not real sure what the extent of mods you want to do, but I have personally been denied warranty on my dealership sourced lifetime warranty on my 2007 Titan. I have also seen other Titans with the lifetime warranty get denied coverage for something as simple as one wrong tire on the vehicle. A Titan owner got a flat, had to buy a tire out of town that didn't match the door jamb tire label, the tire shop didn't have the exact tire in stock and sold him an equivalent size that maintained the load and diameter of the stock tires to get him back on the road. He forgot about it and had an issue, the warranty adjuster came out and inspected the truck and denied the coverage.

Yeah. I wish I could just walk away from the warranty but my wife may divorce me.... LOL

Man, talk about a video that got my blood boiling, but buyer beware for sure.

You can install aftermarket parts like a cold air intake, exhaust, intercooler, and other bolt‑ons without automatically voiding your warranty. U.S. federal law protects you. The key law is the Magnuson‑Moss Warranty Act, and it forces the dealer/manufacturer to prove that your modification caused the problem before they can deny a warranty claim.

The dealer must prove causation
They can only deny a warranty claim if they can show that your specific aftermarket part caused the specific failure.

Examples:

You install a cold air intake → your transmission fails → still covered (no connection).

You install a poorly tuned intake that causes the MAF to misread → engine runs lean → engine damage → they can deny that engine claim, but not the rest of your warranty.

That was 100% my thought process as well.

Keep in mind, that only pertains to a factory warranty, not an aftermarket/dealership 3rd party warranty. You basically sign away all your rights with those.

Yeah , I wish I knew about the 3rd party from the get go. The way they described it was a dealership thing backed by Nissan, not a 3rd party. Yes I should have read the documents closer but with it all said and done I didn't come out of pocket for it. They give it to their customers when you buy a car that is less than 5 years old and less than 50,000 miles. Except for the high end cars.

When you say "intercooler" in the original post, do you mean heat exchanger?

The NISMO CAI, HX and exhaust are dealer-installed options now, configurable/buildable on nissanusa.com (along with coilovers, sway bars and front strut tower brace). Although for some reason the Sport is the only one that shows the exhaust as an option.
