2019 Nissan Pathfinder SV 4x4
Mine is only noticeable when the weather warms up, mostly silent during Winter and it doesn't get too loud unless the engine and ambient are super hot.yep right around, beneath that accelerator pedal, from under,
so jman, you just ignore it? or turn up the radio?
i assume when you are accelerating or driving , noise goes away,
it just comes back when you take your foot off the pedal,
so that makes me think there is nothing loose,
you hear noise, when you are not accelerating, moving or not moving, coming to a stop with foot off pedal
Whoever said the fans were driven by the engine needs to be fired...they are electric and in no way controlled by the motor...at all.Thanks for sharing and welcome to the forum !
I met a Nissan Tech who suggested that same part, here is the TSB for it.
Took it to two different dealers, one first said it was not normal and then, after meeting with the service manager came saying it was normal. The other dealer said it was the radiator fans and when I asked them why the noise increased with rpms, they said it was because the fans were driven by the engine... that was my last interaction ever with a Nissan service dept.
I haven't fixed it yet, now that I know what it could be, I'm not worried anymore.
Great, I am having this same diesel noise and it is getting worse. I will replace the dampeners/regulators. I am glad someone has tried it and it had positive results. Thank you!Hi everyone. For all those who are having this diesel sounding cabin engine noise. Thanks to this forum I was able to take it to my mechanic and tell him what to do. Since the scanner didn’t pick anything up. Upon having the discussion of replacing the fuel dampers (fuel regulators), he told me let’s give it a shot. He replaced it along with new intake manifold gaskets—— and the knocking sound it gone. Finally!!!! There’s also an increase in power. Hope this helps. There are two dampers one in front of the engine. The other at the back of the engine. The manifold needs to come off for that.
I have the same issue!!! The knocking sound wasn’t there before and now it’s there any time I am in idle position. This is my first Nissan and probably my last. The tailgate lift also broke due to rust!!!Dealer just called and guess what... they are now saying that knocking sound is normal...
Said they have another one that does the same noise... guess 2 vehicles with the same issue makes it right !
