Steve, I don't blame nissan, note I couldn't care less for nissan, but they're right.

One of the reasons I tell people to be careful with the aftermarket is this exact scenario. You end up being passed from business to business, person to person on a wild goose chase.
As for the bad fuel, I have no doubt that if the unichip hadn't been installed this issue wouldn't of happened.
If you made me kitchen cabinets and then I modified the rails, only to complain the draws weren't closing properly all of a sudden, you wouldn't cover it either.

Let's be real, this isn't a nissan issue, its a problem with the belief that the aftermarket always knows better, they make you believe that, then a situation like this happens and you're the one stressing.

Stress less, modify less!

Moral of the story, don’t chip/tune a car at least while it has warranty. Same thing happened to a relative of mine with a Ford Ranger. Cooked the motor and then he got played between the manufacturer and the chip company. Both just blamed the other and not putting it in writing etc. Don’t listen to the chip companies about “not voiding warranty as it works within the manufacturer parameters”, as it just gives them both a way to play off each other and leave you with nothing.

you've excepted none of the  blame, and thrown everyone including the people that helped you under the bus.way to go.

Not sure why anyone is blaming Nissan, you have changed the way the vehicle operates, it’s totally on you for the modifications , if the issue is with uni chips device it should be on them, unless you changed their settings then its back on you.

I see it time and time again with the y62 motors.
Leave the engine alone, treat it well, regular maintenance it will be fine.
I see people that turbo it, unichip it, chase numbers with the supercharger rather than a mild safe tune and then wonder why the motors get chewed out.
It’s not a bloody performance car

My new y62 back in 2017 had a bad suspension noise. The dealer tried to fix it but to no avail. Nissan ended up refusing to pay the dealer to look at it again.  The noise eventually went away after nearly 30000km and I still have the car. Will be my last Nissan though as not a great experience for the first 2 years,  even though the car has been generally ok.

I'm  flabbergasted. Why the hell would you throw guys that helped you under the bus?? Are you that entitled that you think everyone else is at fault. The guys that did the reports and left stuff out....... why would you name them? Why did you delete all your posts about Unichiip if its got nothing to do with it. Mate step back a bit and look at your own behaviour and actions.Maybe take some accountability for your own choices.My first time I have ever giving a negative comment, I think maybe my fifth comment ever. Do better

The add on chips are a lazy man's tune. It just fools the factory ecu. Best to have the factory ecu reprogrammed and dyno tuned to check it across the rev range for lean conditions which can detonate a cylinder or head with excessive heat. Too rich you run the risk of oil dilution which then you can sping bearings etc. on a NA V8 I can't see how big the gain would be not worth it. It's a very reliable engine as it's simple. Forced induction petrols or modern diesels pickup alot of power with a tune. You can have the factory tune flashed back and take it back for warranty but they can often check if it's been flashed before. My Nissan had been back 6 times for various items over its 5 years including a gearbox issue renown in the model and never had a claim knocked back. Good luck with the new ride.

To be fair you knew the chip was an issue or you wouldn’t have deleted the content. It was a 50/50 and you lost on this occasion.

My son bought one as well loves it  . i have a y62 similar to yours

There’s so many things that can course your issue and with patrol’s being direct injection everything needs to be right or you end up having problems.
Lastly your right about the irs they take a lot of work to get right

I've read a few of the comments and they're not particularly fair. Without knowing the details ofnthe warranty, generally, a warranty under consumer law  would require Nissan to prove it was not liable to cover the warranty because the Unichip caused the failure. An extended warranty (not under ACCC/consumer law) is effectively a contractual agreement between two parties, and so long as the terms and construct of the agreement are consistent with consumer and cobtract law, the terms of the agreement define what is covered. A verbal agreement is a legal agreement under law for everything accept sale of land, but written contracts will often try to exclude any previous claims etc made unless they're recognised un the written contract itself. The shit thing is, any manufacturer can effectively refuse to honour a warranty for any reason, and the cobsumer is forced to go to the courts or co sumer tribunal (if one exists) to enforce it. This is why insurnace is a thing. They will effectively step in on your behalf, and try and force the manufacturer to honour the warranty. But it's also an absolutely abominal situation to be in, which is why as much as I love my Patrol, I would never go near a Nissan dealership (and try and avoid most others in general).

But yeah- best practice is to record everything, one way or another. The clearer everyone is on the situation, the less likely everyone is to get upset over an issue occurring. As a generality, it should not be unlawful to rely on the verbal agreement regarding unichip with Waverly Nissan (?), but it is more difficult to enforce without some sort of documented record of the agreement, be it paper written, email, audio or video recording.

Ive never had a warranty issue with Toyota for the last 30+ years. I've owned Hilux, 4Runner and now 300 Sahara as full blow off road vehicles. One thing I never did was touch an engine whilst under warranty.

Regardless of what the legislation says, the reality is what has just happened, is case in point… Whether the customers are right or wrong, they are left hung out to dry with these kinds of mod related warranty issues. It happens endlessly to people but people still bite down hard on marketing on chips and tunes all for a bit of street cred. Solution is simple… less is better, don’t fix what isn’t broken.

The pay back on a chip is huge mileage, and if it makes the engine more powerful then you're further stressing the drivetrain. Even in a turbo motor they don't make sense IMO. As far as Nissan goes, the company's behaviour would have been effected by the chip IMO, plus they lost 22% sales volume in Australia and their world operation lost four and half billion dollars, and they have focused on cost control. Which must increase a company's reticence. As far as the rear suspension goes on a Y62, nothing at all wrong with it IMO as long as you leave it alone. Its independent and linked to the front suspension ... it works great in standard form and for off road, then change the tyres a little. And if my engine was knocking I'd not want to drive it, knocking is like hitting a cylinder head with a hammer. But if you had a chip installed, then getting the vehicle towed to a dealer would be a lot more complicated as the dealer would blame the chip ... my guess is that is why you drove it while it was knocking. No idea what your next vehicle is, but don't chip it.

So fuel contamination yet only down on compression in 1 cylinder .. what about the other 7 🤔... there’s either more to this or it’s 💯% the fault of the unichip as far as I’m concerned !

I have a 2019 patrol which has been a great car with a horrible rear end. Nissan dealer in Berwick were the shit ist place to deal with. I’ll only have this patrol and never deal with Nissan again

Yep never chip a car that’s under warranty! Wait until it’s out of warranty then it’s all unichips fault!

You have been around YouTube to know well that installing after market products to your vehicle may land you in hot water down the track. It's 2026 man. The world is full of finger pointers pushing the blame on someone or something else. You need to realize that you are the one who chose this path by adding aftermarket products and the moment something happens you feed the propaganda machine to try and get an outcome that clearly wasn't the one you expected, regardless of your "YouTube Status". It doesn't have to be proven that it's dirty fuel, or an engine malfunction. The fact is, you have gone outside the boundaries of the warranty for it not to be honored. It's not Nissan's fault, it's yours. Getting shitty with Nissan and spitting shit online about your grievances isn't getting you anywhere. Great you sold the car and now your dirty with Nissan. You'll buy another new shit box, do the same boring mods everyone does, come across the same problems and gamble $100k. Maybe I'll see a feature with you and John Cadogan. Watch this space.....

Sorry about the drama with Nissan. Hope you all the best going forward mate. Keep the content up and thanks for sharing.
