Is anyone with a 2018 RX experiencing the dronning issue? I looked through this thread but could not find a 2018 vehicle referenced.

So glad I traded mine in. best decision I could have made. Nothing more frustrating than spending 50k+ and getting the run around.
This is flat out a bad design and varies from vehicle to vehicle, thats why Lexus can not come up with a real fix. Putting dampers on the exhaust pipe, what a joke.

I feel like my new 2018 450h is a bit loud and droney/ grumblely between 1000-1500rpm when accelerating from a stop. For reference, my 450h is much louder than my old 2007rx and even louder than my 2013 Honda odyssey V6. Is this normal, is the 450h even affected with the exhaust issue or would this fall into what folks here are seeing here?

Rear Engine Mount
Here is the service invoice for the repair to my 2018 RX. You can see the work completed regarding the rear engine mount. Vehicle seems much better. The drone noise and vibration are gone. I can feel a slight movement in the steering wheel like a tire (s) are a little out of balance. I will have Discount Tire check on the balance.
Anyone beside RX3502018 have this new part installed? Has it helped?

I’m not sure what vehicle you came out of, but I find my ‘16 RX 450h engine one of the quietest vehicles I’ve ever been in. Perhaps the CVT gives you the perception that the vehicle drones. I could see that. When I compared the 350 to the 450h, the 450h was hands down the more quiet of the two. Also, keep in mind that the 3.5 V-6 is no slouch. It produces a lot more power today that in models past. It’s a given that engines that produce more power, are louder. They often have larger intake & exhaust that will make them louder by nature. Indy cars are not quiet & they are 4 cylinders. The 350 has a flawed rattle/drone in the exhaust that the 450h doesn’t have. Lexus dropped the ball on their bread & butter best selling model & they will pay the price for that as many have walked away. It’s something each owner has to decide, if they choose to keep it & live with it or if they decide to dump it.

For you Geeks.
This is what the rear Engine Mount (Insulator, Engine) Looks like. This diagram is for the old part -- 12371-OP270. The updated part is 12371-OP350. Really hope it helps.

I’m speaking from my own experience test driving. The 350 was a big fat NO for us. You’re results may vary.

I have driven both, too, and Consumers Union and I have had a different experience. Folks may have noticed that those most of us who are happy with their 350's long, long ago ceased making "My 350 is just fine" posts, because at this point in this very long string they do not contribute anything new that is material to a solution for those who may have the problem. Repeated "My 450h is just fine" posts fall into the same category. Even more so.
Go in peace.

This action began when I wrote a respectful email to Lexus stating that the TSB did not fix the exhaust noise problem. I was assigned a case number, and was called by a Lexus customer service rep the next day. I was told the dealer would call and arrange to take my car back in “to see what they could do.” I didn’t expect much.
The Dealership is 1-1/2 hours away. I picked up a loner (2017 RX with a droning problem - just my luck), and the next day the service advisor called and said they were waiting for a call from the Lexus engineer. Nothing was done that first day. The next day, the advisor called and said they had heard from the engineer, and wanted to try a new rear engine mount, which is an “updated part.”
The part did not come in until late yesterday afternoon, so the Advisor said he would call me when it is ready today.
To answer the question, I don’t believe it is a TSB. It will definitely be covered under the warranty, but I really believe the effort is all about good will.
I am hopeful. I purchased this certified 2016 RX in May. I will let you know if the new isolater mount helps.
