2016 RX350 Engine Idling Issue
Created a new thread for the issue since I think this may be unrelated to battery replacement as I may not have noticed it earlier. The car in question is a 2016 Lexus RX350 F Sport which I bought used with around 42k miles on the clock. The issue is that sometimes when I am simply standing at the traffic the light with transmission in D, the idle rpm is not constant and it keeps jumping by about 150 rpm or so. Even otherwise the rpm needle is never rock stable as it should be but it could be due to the fact that the rpm instrumentation is fully digital in F Sport and there are 20 notches for every 1000 rpm with each notch corresponding to about 50 rpm and therefore even slight variations will be caught. The question I want to ask my fellow Lexus mates is
1. Is your RX350 idle rock steady? Meaning when the engine is fully warmed up, can you see the rpm needle jump a little however slight (you may really have to look for it). 2. The issue with my car is idle jumping by about 150 rpm standing still and doing nothing. It was reported when my Lexus went in for service for other smaller issues (thread link: https://www.clublexus.com/forums/rx-...placement.html) and while I was able to recreate it whenever I wanted to (gentle stop to complete halt and the rpm needle will fluctuate), I can no longer recreate it. It now happens when it happens. Also attaching the video of the same happening on two separate occasions. I am using premium 98 octane gas. What do you think could be the issue here? https://photos.app.goo.gl/igQFXMF3yzzUUygXA https://photos.app.goo.gl/JrHDDvtwmcCTRZBY8 3. What is the technical spec for the idle rpm for this engine if you know? I tried searching but could not find anything. Usually it is specified as xxx +-xx rpm Thanks a bunch in advance and a very happy new year! |
Both of my RXs are rock steady.

Thanks for sharing the video. My 2016 Rx F sport (Canadian made) does the exact same thing. I had always thought this was abnormal...

Have you showed it to Lexus? What do they say? I am sending my car in for service tomorrow. Will keep this thread updated with the findings.

my 2017 F sport does this as well, this is normal. Like you said, there are more lines between each RPM so it shows the slightest movement. I wouldn’t worry unless your experiencing other symptoms such as shaking when the idle moves. I’m pretty sure we won’t find an F sport that doesn’t do this. Let’s wait for others to confirm

they compared it with another 2016 F sport on the lot and said that they both do the same thing. Their conclusion was that this is normal, based on the fact that both vehicles do this.

i was looking for someone who got the 2020 f sport and had the older one. Did you get the AVS or standard suspension? Was curious if the new AVS is better then the previous years

Can you hear the engine revving inconstantly, when the tach is moving like that?
