2016 RX 350 Noise and Vibration - TSB repair w/service record
1 Attachment(s)
All, I recently purchased a 2016 RX 350 FWD with 31,000 miles. It had the vibration. I read through this thread. Very helpful. thank you all for posting.
I decided to take it to the San Diego Lexus dealer armed with the TSB info. They did the repair under warranty. The car now has ZERO vibration at any speed. Very satisfied with the result. My work order is attached. Thank you again all for contributing. I learn a ton from this site and this is my first post. Thought it was time to give a little back. |
Since the Lexus fix doesn't seem to work for a lot of people including me, I wonder if anybody has tried taking their RX 350 to a regular muffler shop to see if they can solve the problem?
I took my 2017 RX 350 AWD in for the fix. When I picked it up, the dealer told me "it's much better now." However, I found it to be much worse than before but I'm afraid to have them do any more for fear of them making it even worse. |
Got a 2019 ES 350 as a loaner today. No noise, no vibration, just smooth ride. It is sad that a cheaper ES is better than our RX :egads:

The ES is on a completely new platform with a complete redesign. The current RX is just a warmed over Gen3, which is a warmed over Gen2..well you get the idea.

Oh dear, no wonder there are vibration/noise problems! I was under the understanding that Gen 4 was all new from the ground up... |
Comparing an ES to an RX?? They are a different animal, one being the latest in a sedan platform, and the other and old platform in an SUV body (rear wheels in cabin).

Military/civilian aircraft and ships can easily go fifty years with the same platform. Nothing wrong with keeping the same basic components as long as they are good ones.

I wouldn’t argue with that logic. In my own aircraft experience, I have seen where a platform is continuously improved & flaws are eliminated with each new update. However, this doesn’t appear that good & the same flaws carry over from year to year. I’m not trying to be critical of the RX, it’s just an observation. I haven’t had anything major with my RX, but I’m not sure I would go jump on a new one. Everything that I was lead to believe about the RX being extremely well built & reliable is out the window. I just noticed that my rear seat cup holder is broken AGAIN for the 2nd time! No one hardly sits back there. The design is stupid & totally unreliable. My biggest complaint is that Lexus is ignoring the little things that add up over time. |

I wouldnt compare a car platform to aircraft and ship platforms that was designed to handle extreme conditions constantly. The 2 times I had an RX, 2010 and 2011-2013, I was very disappointed. It had a lot of road and wind noise and lots of impact harshness over bump. And watching video reviews of the current gen, that doesnt seem to have changed.
I think part of the problem is that we expect an SUV to behave like a luxury sedan. The RX was not designed to be like an LS. The RX, by design, rides a little stiff, and is a little noisy, but it’s an SUV. I do think there are problems with droning, and shifting hesitation, that Lexus is trying, unsuccessfully, to address, but the basic RX platform is fine. |

You have a point, but I flew my 1949 Cessna 140A for many years, and it is still flying. Likewise I rebuilt my 1949 Harley Flathead, and 1957 Harley Panhead, rode them, and they are both still on the road. A lot of maintenance - you betcha, but pretty good platforms.

I’m convinced that Lexus hasn’t really tackled the droaning at the level required. I worked with some university engineering departments to try to solve harmonic oscillation cracking, where metal poles vibrate in the wind and eventually crack. All metal oscillates. Some frequencies are destructive and some are not. Usually, some form of dampening stops most destructive frequencies (similar to installing Dynamat). This is why I’m hesitant to go further with another Lexus. The RX isn’t their most expensive, but they sell at least 3X more RX than any other model. Why wouldn’t they just solve this?! This problem has come down losing customers vs. spending money for a solution. That usually doesn’t end well for a company’s reputation. |
2017 rx350 drone issue service completed-results
I received back my 2017 rx350 (fwd) from the dealer with the exhaust center pipe assembly fix applied. I was also there for the ICS recall, 15K service and an ongoing janky transmission shifting complaint. (I've had complaints about the transmission hunting/shifting and the drone since day one, however it had had recently become much more noticeable to me and all occupants in the car). I can see the updated center pipe, but don't know if they ever previously scanned/connected to the ecu to see if the transmission flash was done (per the VIN it was always relayed to me as such).
Complete night and day difference. I couldnt be more (surprised) pleased to have this fixed and now have the RX that shifts/sounds like our old 2002, 2007, 2011 & 2015 used to do. worth a mention i hope and if you need a scan of my *invoice* I can post up the part #s! |
