I've started to notice a drone noise when stopped, and a light vibration in the steering wheel. Almost sounds like my RX has aftermarket exhaust.....is this similar to what people have been experiencing? I bought my RX350 F in June, 2017 (about 12k miles to date).....not sure if TSB had been applied once Lexus started to catch wind of the issue.

“Drone” noise fixed
Job work order.
Had the center pipe replaced and Drone noise is now gone. Much quieter. Sounds like the 2018 loaner I had.

rx 350 2018
This is my first new car ever. I leased it because my dad died and I realized I should treat myself. It is beautiful, it is broken :-( I got it 8 days ago with 1700km on it. It was a demo. It makes a terrible noise and vibration at 35-40Km/hr and 50-55km/hr when I am accelerating. I am devastated, this is an expensive suv and I only wanted lexus as I wanted smooth and quiet. Now it vibrate like crazy and makes a loud humming noise when accelerating through thos gears. I not that most on this thread are from 2017, did lexus get a fix for it? I am taking it in tomorrow. Has anyone successfully managed to get lexus to take it back and give you a new car that doesn't do this? I am so sad!

Good luck, let us know how you went.

This is a follow up after a week of driving with the center pipe TSB done. I never realized how much noise the old system made even at normal driving speeds . My service adviser told me he could hear my noise on the road. It was not just the “drone” noise at 1400 RPM. The funny thing is now I can hear my tire noise when slowing down (Michelin). The noise level is much lower at ALL speeds. I do not know if this is the latest of the TSB fixes or if they are all the same. Persist in getting this done if you have one of the vehicles that have this issue. It is not just a isolated issue. When Lexus issues a TSB fix it is because there is a recognition of a issue that is more than a isolated situation. I know most owners do not have the issue but for the ones that do I fully understand the frustration of hearing the noise on a vehicle of this caliber. Lexus is not denying the existence of this issue.

I have the 2018 rx which I purchased in Feb 2018. As soon as I left the dealer lot I noticed the noise and vibration. As with many of the posts here, the noise occurs at about 1500 rpm especially when the transmission upshifts. I immediately called the dealer about the problem. Shortly thereafter I made an appointment to have their technician ride with me to assess the problem. The technician verified that my car has the noise/vibration issue. The dealer response was to order and install the new exhaust pipe with the vibration damper. This fix seemed to help but by no means fully remedied the problem. A few months later the dealer called and offered to install the engine mount separator which I had done. This fix did essentially nothing to improve the problem. I was told that my experience would be forwarded to Lexus and I would be notified if any other solutions became available. So far I have heard nothing new.
As for my additional two cents, when I looked under my car at the new parts, I noticed the array of splash shields which many new cars now have. One thought is that while the source of the noise/vibration may be the transmission and/or exhaust system, the splash shields are picking up the vibration and amplifying it so it sounds louder. Just a possibility.

I have a 2016 RX with the noise problem, and a 2017 without the droning noise issue. Both are CPO vehicles that I purchased earlier this year. I have posted many times here on my efforts to fix the 2016 noise, and it is time for an update.
I first installed a muffler clamp and weight in front of the catalytic converter that Walt1953 (page 19 on this thread), and pgn628 (page 31) wrote about. This worked well, but I was concerned about the effect of the weight on the flexible joint, so I removed it. Next, the exhaust pipe TSB was installed, which, in my opinion, made the noise worse. The dealer then put in the updated rear isolation engine mount which had no effect on the droning noise. I found that removing the weight attached to the TSB center section reduced but did not eliminate the noise.
I reinstalled the TSB weight and added Walt’s weight in front of the converter, and was surprised that the noise was not reduced. I then, once again removed the TSB weight, and the droning noise was essentially gone. I have talked to a few experts who have agreed that Walt’s invention will not harm the flexible joint, and should not effect the warranty. Just don’t crack the weld at the front of the converter. The car is quiet, and I am a happy camper.

All is still quiet on my RX after the replacement exhaust part was replaced. Make sure you get the latest one as I believe there may have been some modifications as time went on. It has a fairly large weight attached to it with a flexible mesh type material on the pipe for flexibility. I have driven it about 1000 miles.

Does RXL 350 have the Vibration/Noise issues ?
Hello,
I am considering getting a RXL 350. But I am worried about the vibration noise issue that has plagued the RX since 2016. Is this issue common on the RXL? Thank you for any input!
