Based on this thread we decided to pass on Lexus and buy an Audi Q5. By the way my two neighbors who own the 2011 RX have them serviced at Toyota at a tremendous savings.

I just found out a weird thing that the drone noise and vibration decreased when I use regular gas! (was using Premium)
The noise and vibration happen mostly when driving in city with eco mode. Per manual, city driving should use at least normal mode.
With normal mode and regular gas in city, I barely feel the noise and vibration.

The bolded portion might be where a lot of people are having issues.

Anybody had a YouTube video of this issue? Just want to compare it with my 2016.

I have driven FWD RX350 and RX450H as loaner car for at least one week of each. Mine is AWD RX350. All are regular one not F sport. I feel the FWD RX350 definitely has the most noise and vibration. 450H just had slightly drone at certain speed. Also the 450H feels to have less wind noise at high speed (>70 mph). So 450h is definitely the most quite one. But since I have driven only one of each, I cannot conclude AWD is better on this. But this is something you may need to pay attention if you are going to buy one.

Mine has no "noise and vibration" at all, so your experience does not apply to ALL FWD 4RXs, just saying. All mine does is upshift too soon in drive.

Any resolutions to this issue? My dealer says it applies only to the fwd models, not the awd. Any truth to this?

I was shopping for a rx350 and I told my sales man I was going to wait bc of the vibration. A few days later he call me and said that the vibration is only in fwd. his master tech say it has something to do with the exhaust. Maybe people with AWD can comment.

Have an AWD F Sport and never had this problem.

My 2004 RX330 has problem 1 as described. I brought the car to dealership, after the technician test drive, they said "it's normal". And I have tolerated this for more than 10 years already. By the way, the VIN of this car shows it was made in Japan.

After more than 10 years, it is obvious that Toyota or Lexus did not correct this issue. Just as a Toyota top manager quoted few years ago -- "Quality of Toyota has been not as good as before since they want to reduce the cost of production in order to become bigger." So, don't expect TOYOTA is as reliable as you expect.

I'm confused by what fellow lexus'ers mean when they say "drone". Is it that the engine is at a very low rpm and higher gear? Does it go away if you give it gas and induce a downshift? Is it always there regardless whether light throttle or aggressive throttle. Those with this issue please enlighten.

My 2016 RX 350 has had multiple problems with vibration and noise. First "fix" was putting a motion damper on the exhaust. Second "fix" was padding and realigning a splash guard. (these are what my dealer told me). I now notice that the car occasionally has vibration and noise when stopped and in gear, such is at a stop light. Has anyone else had this problem? It's almost as though the automatic transmission doesn't always disengage sufficiently when car is in Drive and the brakes are on.

There are some owners on here saying no problem at all. I find it hard to believe that the problem is there for some cars and not others... Lexus has a very high degree of compliance to their design standards. So unless the design is problematic it leaves only the possibility of materials/workmanship flaws in some parts which ought to be an easy fix. I think it is more likely design related and perhaps subtle enough that some drivers don't notice it or care, or their driving style mutes it. Any thoughts?

The two recommended "fixes" from Lexus (exhaust motion damper and splash guard realign) did help some, but still more vibration than I expected from this car. I felt the engine both at idle in Park and at idle with the car in gear, and there was significant vibration, increasing noticeably when idling while in gear. When I asked the shop foreman at the dealer he said the 2016 engine is a redesign with higher compression, and that the amount of vibration I was feeling was normal.

Also, a noise I was hearing from the passenger front was apparently due to a problem with insufficient Freon (or whatever gas they now use) in the air conditioning. Dealer flushed and refilled my system and the noise has stopped.

I had my RX 350 in for service on Friday. I complained for the second time about excessive noise and vibration upon acceleration. On my first visit the dealer stated the vehicle was within normal operating perameters for that model and there were no issues.The customer service agent asked if I would like to ride along with the technician and explain the issue. I agreed to do so but the technician stated it was not necessary because he was aware of the problem and it had been communicated to Lexus previously. ​He stated that my vehicle was especially bad and he would contact Lexus corporate and report the issue again and would be back in touch.

Confirmation from dealer confirms to me this is a known issue and Lexus corporate has failed to respond. As a first time Lexus owner, I expected better.
