Engine noise
So Im passing on my next 500 miles on the odometer. Im very impressed with my NX F-Sport thus far with the exception on the engine noise. I know it's a 4 cylinder but it dose seem to be loud coming through the engine compartment into the interior. Sounds like a struggling 4 cylinder. I can hear the turbo whirling but engine seems loud for a $50,000 price tag vehicle.
Any thoughts?

I've tried both on and off with that Auto Sound Controller. Don't really hear much of difference. Don't get me wrong the engine is performing nicely so far but just seems like a heat shield or something is vibrating.

There must have been something wrong with your ES-300h. Our NX-300h has considerably more noticeable engine noise than our ES-300h. In our case, the two cars have the same 2.5L internal combustion engine. it definitely isn't the typical quiet Lexus ride, but it isn't terrible and according to a simple phone app, about 3db quieter than the RDX we drove. We just hear quite a bit of general engine groan but some of that is expected with the hybrid drivetrain.

Any update? I recently ('15 F-sport, 8K miles) am noticing a humming noise while my engine is running on idle. It's not there when I first start the vehicle, but after I drive the noise seems to show up. Don't remember ever hearing the noise before.

Sorry guys I have the non f sport and I don't hear any noise from the engine. It is for the most part quiet. I don't think it is and different from a 6 or 8. Yes other 4's from other manufacturers are very load and noisy. I find the Lexus 4 smooth and quiet.

Noisy?
I think this SUV is a lot quitter than my turbo, 4 cyl. SUV that I traded in (RDX w/ turbo) The NX200t is quite for a 4 cyl., turbo'ed that creates this much HP & TORQUE, there is going to be some noise, but I think this one is just right for sound. It's there, but pretty quite for what it is!

The pursuit of F
So to chime in... For a 4 cyl, notwithstanding the occasional 760 rpm rough idle I experience, this is the smoothest and quietest 4 cyl I've experienced to date, across the entire rpm range. The Ford 2L Ecoboost for example is as smooth and quiet up to 3500 rpm, but becomes louder and harsher to redline. Compared to my IS 250 and RC F, it's 99% as smooth and 110%+ quieter

6 weeks pass now. I do feel the slight vibration when idling at times.
Last night I drove our 2010 RX for the first time since purchasing NX.
So smooth at idle. Too bad the NX doesn't feel like the RX.
I am so hooked on the alert/safety functions on NX, I found driving the RX almost seemed dangerous.
We are now looking to replace the RX.
Looking for performance coupe. I.e. BMW 425 or Audi A4.
Wish Lexus had something comparable.
IS is too small; will look at GS, but it's hard to pass on BMW elegance.

Lexus does have a competitor in the coupe segment: the RC, which has a turbo-4 option now like the cars you mentioned.

Performance coupe or sedan? The BMW 428 (not 425) and Audi A5 (not A4) are coupes, but I wouldn't consider these "performance" coupes with their turbo-4 engines.

+1 on the RC and best option (as you both know) for long-term ownership.
I miss the RX's V6 idle smoothness too and for those who would prefer a six over a turbo four like myself, it may be coming up in a '17 or '18 as per the registered "NX 300" moniker.

The advisor said the technician ran a diagnostic and everything check out fine. The tech even noted in the paperwork that he couldn't replicate the noise. Knowing that my 10K maintenance was coming up, I decided to just drive it and hope it would work itself out. When I drove home, the humming noise was still there. Wishful thinking.
Yesterday at my 10K maintenance, I made sure a tech confirm that he hears the same "humming" noise. He initially thought I was talking about the coolant fan, until we went on a test drive and I replicated the noise immediately. Tech believes he has isolated the noise and has a part on order, but they are having a district/regional rep to come out and check it out in a few days. Will keep you posted.
