Ticking Engine Noise
Does anyone know what this ticking noise might be? I've had the '17 rx350 for about 1 month and notice this when I start the car up and pop it into drive or reverse. It gets faster as you start driving but then goes away after about a few minutes.
They just replaced the vacuum pump saying that was probably the issue but I would love to get your guys take on it from the video. Hopefully you can hear it over the open door buzzer.

100% positive that is not injector tick(Unless the echo is making it deeper). Sounds more lock a knock and can be an assortment of things. Injector tick sounds like a sowing machine.
Does this only happen on a cold start and goes away?

2019 rx350 fsport popping/knocking noise (possibly other years too)
Hey guys
I have got a 2019 rx350 fsport with about 2700 miles and I noticed at around 4-5 mph the car makes a popping/knocking noise.
This only happens when the car first starts up.
If you drive the car around, put the car in park, don’t shutoff the car, then put the car back in drive it doesn’t make this noise.
I have attached a video
Can anyone with a 2016-2020 rx350 confirm this noise?
I am wondering if it’s year specific, f sport or non fsport specific.
this is NOT the ticking noise the OP is referring to
Im not sure why my separate thread got moved here
This is ONE pop/knocking sound and that’s it.
Thanks in advance

Just wanted to update you all. My wife just got her car serviced and they said the engine ticking is normal. I'm going to send the video you posted to my indy mechanic that i use for my cars and see what he thinks.
Edit: i told her to see if they'll start up a loaner RX for her while she is there to see if the noise is "normal". will report back

Yeah we didn't have time to refute any of this with the service adviser this go around. We also have a very rare, but violent (for a rattle) rattle back near the sunroof (non-pano). Service adviser said this was sunglasses. To be fair, we need to get a video of it next time because it's tough to replicate. Will post back eventually once i contact my mechanic.

Could it be this? Did the sound get better after they replaced the vacuum pump?
Apparently this affects ALL 2016-2018 Lexus RX vehicles, but haven't heard this vacuum pump TSB being talked about much.

Cold engine start rattle
Immediately following a cold start the engine was producing this noise:
Dealer identified a service bulletin and replaced the vacuum pump.
The noise is still occurs (around 0:30):
Has anyone had the same problem and if so, were they able to get it fixed?
