New Y62 owner but massive issue from new

[steve_bunkle]

Hi all,

My name is Steve and we purchased our dream family car last week, a series 3 Ti in Ivory White. Rather than put in an order and wait, we found a new example a few hundred km from us. We went from a 2014 Hyundai Santa Fe but wanted a "proper" 4wd and the y62 ticked the boxes even without a diesel engine. I spent months researching them, talking to owners and looking at reviews. No one seemed to have anything bad to say except for the thirst if driven in slow city conditions.

I have joined the two Facebook group (y62 Patrol Owners Australia and Aussie Patrol y62) but have always liked to me a member of a traditional forum. I have been a regular contributor of the Australia Magna Forum for many years and have found that a great way of keeping in touch other enthusiasts and to solve issues along the way.

First impressions were clearly very good with space, great build quality and standard features (at about $15000 more than the Santa Fe when new, you can clearly see the value compared to the Hyundai). And that V8 that impresses just about anyone who drives or rides in one.

Now to the major issue we have that I am desperate to obtain some input from other owners. Our example has a interior noise that is driving us crazy. Every single bump on the road is transmitted through the body into the cab as a very low frequency throbbing/drumming sound. More uneven surfaces at low speed are worse. This has destroyed the low NVH levels of the car which would otherwise be super quiet on the road. It otherwise drives as expected with plenty of power, smooth gear changes, straight-line stability and a rattle-free interior. To be honest I've never been in a car with a similar sound. One way to describe it is trying to sleep next to a house having a loud party and all you can here is the thump of the drums through the alls, except it is very bump on the road. Also a little like the noise you get when you drive with a half open rear window. You can make out the noise just rolling at a few km/hr in a carpark.

The local dealer has had the car once so far and acknowledged the issue but has had no luck tracking down the source. They are currently waiting for Nissan Australia tech support to get back to them. It such that I will have to leave it with the dealer/Nissan until it is fixed, otherwise the car is not usable in my opinion.

I've been under the car myself and the only possibility I could find was the metal shield over the fuel tank. I removed this for a test but it made no difference (is back on now).

I wonder if this be a resonance through the hydraulic suspension system? If anyone has had a similar issue I would appreciate some input. Given I have never driven another y62 then I have told myself this could be normal for them but can't imagine this to be the case. I have one friend with a series 1 T1 locally but her car is away on a central Australia trip for the next 2 weeks.

In the meantime it sits in our carport unused................
