I picked up a used Pro 4X from a Ford dealer and discovered this issue (watch video) the next day. The local Nissan dealer said it's a truck and unless there is a check engine light there is nothing wrong. I have heard of a "rough idle" issue but not sure if it looks like this. Please take a look at the video and let me know if you have ever seen this of know how to fix it. I also contacted Nissan USA and they told me to fly a kite.

You can hear the sound change when I go between drive and neutral. The sound is coming from the steering wheel. Towards the end I give it a little gas to increase the idle and it quiets down.

JESUS, you bought it like that? you didn't realize that was happening right away?

It's something loose, sounds like a glove box rattling, even though thats not it.

That's NOT normal at all, the engine is normal though? like go outside open the hood and listen to that, could be something very simple like my issue, very similar, was nothing more then the heat shield around the cat touching the exhaust, better yet go check out your exhaust system out completely.

This is going to sound real dumb, but i searched for the same rattling at idle for the first month or so. When i was in the driver side it sounded like it was coming from the passenger side and when i got in the passenger seat it sounded like it was coming from the driver side. I finally realized it was my sunglasses in the overhead compartment. That is probably not it for you, but the point is to eliminate all the small things first. Anything in the door bins, center console, overhead compartment, glove box, cup holders, steering column adjustment lever not tight, etc......

This. My overhead console / sunglasses compartment gives me a rattle once in a while.

Also, crawl under with the engine cold and give each exhaust heat shield a grab. The clamps Nissan uses are known to rust and come loose. Easily fixed with a hose clamp if you find one.

It didn't show up on the test drive and doesn't occur until the engine get up to full temp. I pretty much drove through neighborhoods, then the highway and pulled back into the dealership so unfortunately didn't catch it. Genius service advisers at my local dealer said it's "normal".

That sounds like something in the blower motor of fan to me. I could be wrong though.

Cooling fan blades hitting the shroud? Anything in the UPPER glovebox?

I seem to recall there was an issue w/ a fuel line not being secured to the firewall? Anyone else recall this in the last year or two??

I agree that this is likely something just loose rattling. sounds like rattling against plastic, like the sunglasses thing, but may be as serious as a heat shield around the exhaust. i wouldn't worry as long as there is no vibration while driving but it would drive me nuts enough to find the culprit immediately. funny thing is the previous owner probably got rid of it scared something serious was happening. of course the dealership said nothing is wrong, they won't admit to anything because then it means they have to spend money to fix it...

I agree with Cdcarter. It,s the easiest to check at least. Once you’re at operating temperature and the rattle starts turn your A/C - heat system off. If it stops then Bobs your uncle and your problem is pin pointed.

I'd lift the hood and stick my nose under the truck.


Heat shield is the first thing I'd be looking for since it startes at upon warmup....


Next thing I'd look at is anything going through the firewall like steering or in the vicinity of and harnesses.


Next thing I would do is stick my nose under the dash and see if anyones been playing with the radio/console.
but if I didnt find it right away I wouldnt be worried.

So I went to a non Nissan dealer and spoke to a service tech that actually seemed to know something about vehicles. Long story short it seems to be the center pipe on the exhaust that's resonating into the rest of the vehicle. Now to see if the dealer I bought it from will honor the warranty.
