2014 IS350 Engine noise
I've had this engine noise on my 2014 Lexus IS350 for about three months now. The noise always occurs after starting the car up and driving for the first 15-20 minutes then it goes away. I've taken my car to two shops already, but none have been able to determine its cause. I created the video below (please turn the sound up) so that you can hear the recorded sound.
Any thoughts?

Does the noise change when you change speeds?
Does the noise change when you turn?
Does the noise occur when the vehicle is stationary and running?

The big issue I have is that by the time I get to the repair shop, the noise is normally gone. Additionally, the only way to hear the noise is to go over 50mph which a lot of auto repair shops aren't not willing to do for whatever reason. I have an appointment today so I’ll ask to check for the exhaust leaks.

When the noise is occurring, if you sway the car side to side (Sorta like driving through a mild slalom course) does the noise change? If yes, then likely a wheel bearing, if no, then I would look at the tires.
How old are the tires?
What brand/model are they?
Also, when the noise is occurring, if you take your foot completely off the accelerator, does the noise stop?

It does kind of sound like the howling of a bad wheel bearing, but it would be odd for one to fail on a 2014. Try swapping the front wheels to the back and see if the noise and vibration changes to see if it has to do with the wheels/tires at all..

My 3IS just developed this same type hum/squeal sound (but higher pitch) right between 70 and 80. It's currently sitting inside Lexus service garage so will wait for their findings hopefully tomorrow. I'm 100% sure it's not the tires coz I can hear the separate tires sound whenever the car rolls into a cement/non-asphalt road.
I don't think it's a drone coz it's coming from the front of the vehicle.

Quick update on this: Just hanged up the phone with Cherry Hill Lexus and they replaced the wheel bearing on my car - not sure which one/s but I'm glad it's NOT the Michelins or the headers or the modded lower airbox. Will post the report sheet here when I get my car back.

So it turned out that my rear tires had some uneven wear and the rear shocks leaking because of the crappy roads and construction projects in my area. I ordered replacement tires at Tirerack and the shocks from Lexus of Akron and my car has gone back to being quiet once again. Definitely not a cheap fix, but it's my second repair, aside from wheel and tires, in the near 7 years I've owned my car so not bad either.

i remember a story of a Pot Hole so bad that someone literally threw a twin size mattress in it!
i would check with NJ.gov but if its like D.C., gov may help you recoup some of that Money for those fixes:
"Drivers who unexpectedly slam into a pothole on D.C. streets can sometimes get the city to pay for the damage, and last year, one driver got more than $6,000."

Also, I still had a low growl while driving which turned out to be a faulty front passenger-side wheel bearing.
I lucked out for years not having any major repairs but these past 3 months of repairs have burned a hole through my wallet. I'm hoping I won't have any other issues for a while now.
