There is no resolution to this issue, I tried everything. My dealer says they are working on a fix but it's going on a year now.When other dealers are saying its normal makes believe this is very low priority for them. I thing we just have to live with it or trade it in a take the loss. Funny I knew at some point I would get a car with some type of problem that couldn't be resloved, just didn't think it would be Lexus that's giving me the run around. Live and learn, goodbye Lexus👎👎👎

First, you need to ask yourself some fundamental questions. How much does this noise bother you? What are you willing to endure to keep the car or to get rid of it? Are you willing to take a loss, just to be free of it? Once you have solid answers for each of these questions, you can proceed.I see you are in TX. How many documented times has the vehicle been in for service for this problem? You MUST have a paper trail! It’s usually better to have more than one dealer’s opinion in the mix. If you do have your trail, there are a couple of really good lemon law attorneys in the DFW area. I would contact them & see what they think should happen. Possibly, the vehicle could be bought back by Lexus. Or, Lexus might give you a cash settlement & you do whatever you want with the vehicle. Finally, you could just sell it or trade it on another vehicle & start over. You have many choices, but this will not come easy or quickly. I had a lemon bought back, & it drug out for what seemed like forever. It was worth it in the end, because my vehicle was continually getting worse. It doesn’t sound like that is the case with you, but I’m making an assumption based on your writing & not the facts of the case. When I test drove the RX 350, I heard the noise & it concerned me. For me, I would have pursued legal action already, because I simply don’t want a $50,000 car that rattles like junk. That’s my take. You have to do what’s best for you & your family. Good luck!

My RX 450h doesn’t have the noise either & I’m very grateful for that. The chances of a class action lawsuit happening is rather slim. That’s why I advised to file on the lemon laws. Each owner has specific rights & there is always a chance Lexus will fix the problem or settle each individual complaint. It’s a case by case basis. I would certainly hope Lexus has made improvements on this issue after two model years, but I noticed in my most recent Consumer Reports magazine that Lexus has fallen from the top ranks & many lesser known quality vehicles have made significant increases. After touring the Lexus RX plant in Canada, it’s crazy to think that Lexus is ignoring so many folks that have this issue. Don’t give up - the squeaky wheel always gets the grease.

- I catch myself babying my new car way too much. If I drove it the way I did the car I replaced, I’m sure drone noise will not be as big an issue, not at all. I am still way too easy on the gas pedal, sometimes comically so. If I may, the throttle is very touchy though, and that does take a lot of getting used to.... which probably why a lot of people started out getting used to the car and driving it super gently in the beginning.

- Gas quality seems to affect whole car. I can definitely tell a difference in bad tank to the next and try to stick to one brand and station in town.

- finally I love my rx the most in sport mode. I wish the car stayed in it for restart. Eco is terrible. Normal is just ok. Sport puts it in just the right mood.

I dont know about the rattle issue but I am certain that the noise and vibration issue is 100% mechanical. I have minimized mine by installing exhaust dampers as others have done. Changing software could some what mask the problem so you wouldn’t be in the RPM range where the vibration occurs. Anywhere over 2k RPM is silky smooth. I still believe this is strictly a poorly designed exhast issue. Lexus will probably redesign the exhaust at some point. Unfortunately it does nothing for the folks that spent big bucks and are extremely disappointed like myself.
