Lexus RX 2010-15 :: RX350 Engine Ticking / Knocking And Rattling On Cold Start
Mar 8, 2011
I just purchased a 2010 RX 350, has only 7k miles on it. Really, really nice car. I noticed for the first time yesterday the engine ticking/knocking/rattling/whatever you want to call it sound when starting up on a cold start. It definitely goes away after about 5-10 minutes of running.
Most people seem to accept this as "normal". They hear it, live with it, and they never have any problems. I am a new Lexus owner, so I have trouble digesting that such a luxury vehicle with so few miles would have a "normal" engine knocking sound at 7,000 miles.
A few people posted in other places that this is indeed an issue, and should not be happening. There is a a Toyota (Lexus) service bulletin that I didn't get the details on, it is LSB-0028-09. LEXUS: ENGINE TICKING NOISE AND/OR MIL ON P0014, P0015, P0024, P0025, P0017, OR P0018. ENGINE MECHANICAL. *PE
Looking for details on this service bulletin, and if it does indeed apply to the engine knocking sound.
- Premium gas
- High viscosity cold synthetic oil
- Dealer fixes issue
- Other fix?

What is this metal on metal noise...you hear it the best around the 7-12 second mark...it is especially loud on cold start in the morning when you put the car in "drive" but don't move the car forward. It also is prevalent on hot days when you park the car outside and just start the car. The sound gets louder when you turn on the a/c during the hot day.

I just punches a 2010 Camry 4 cylinder with 44,646 miles. Very clean. I've owned 2 camrys in the past a 97 and 2002 that both reached well over 200,00 miles without a hint of trouble. Well, when I start the 2010 when its cold like from overnight it sounds like the lifter are ticking?, it lasts until the engine is warm and then I don't hear it. It still has the 2 month 3000 mile warranty from the dealer. I just don't seem to remember our other Toyota sounding that way.

I have a 2011 RX350 and recently noticed rattling sound coming from inside the glove compartment.
I think it comes from the plastic cover of the aircon filter at the back of the glove compartment. This cover seems bit loose even when installed back properly and the vibration (especially when driving over uneven roads) is causing the rattling sound.
I know it's a minor problem but the rattling sound can get irritating at times. My temporary fix is to push back the heavy owner's manual on that cover to prevent vibration.

We own a 2013 RX 350, purchased less than a year ago. We are experiencing this rattling noise coming from inside the side panels, its frequency changes depending on road and weather conditions like if road is rough or if its windy. We have taken the vehicle to Lexus Service three times so far for the same issue, they have acknowledged the issue. Last service took almost a month but still no remedy.
As of last service, Lexus took the entire roof liner down to fix the issue but it came back after one day post service.
Noise is extremely irritating because it occurs next to driver's left ear and is annoying as anything can be. Same goes for right ear for the front passenger.
We have owned Nissan Maxima, BMW and Lexus before and none of the vehicles had this issue.

When the engine of my 2007 Camry LE V6 is cold, it makes a ticking/knocking sound. The engine has 100,000 kms on it (60k miles). The frequency of the sound varies with the speed of the engine, not with the speed of the car.
When engine is cold: The sound happens roughly twice a second when the engine idles (at 700-800 rpm).
When engine is warm: The noise is less audible. It can be heard when idled at a stop, but you have to listen for it. The noise cannot be heard on the highway.
The car doesn't burn oil, and the oil level is ok. I had the oil changed 3000 kms ago, and it is still very clean (clear). The was the same before and after the oil change.
I am wondering if it could be the lifters, bad plug, or maybe a timing issue.

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.
I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.
Almost sounds like a lifter is tapping due to not getting oil.
I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.
Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

I have a 2001 Toyota Tacoma that has a knock or ticking in cold weather. The problem starts sometimes immediately after I start and other times it is only when I press on the gas in the cold mornings after a few min warm up. The noise goes away after 10 min. The question I am wondering is this:
1: could it be worn piston rings and the pistons are slapping the cylinder wall
2: is it an oil pump problem or a oil restriction issue
3: is it a valve guide issue
4: with the history of the 2.7 having exhaust manifold issues (poor manufacturing) could a cracked manifold be the issue
I change the oil myself, the oil filters have been OEM toyota, the noise has been going on since 60,000 miles, the truck is at 230,000 miles.

I had a garage connect a computer to my 2013 rx350. It reported AC problem. It does not say what is wrong with it. What that actually checks on the AC ? I don't get cold air so I bought an AC kit to try and recharge it.

Got my CPO 2012 RX350 in July, everything has been great
winter has been tough here in the north with -30 Celsius (-22 F) every other week. when it's that cold there's squeaking noise from the dashboard / windshield area. mainly from the intersection of both.
Once the car is out of the garage it's ok for a few minutes then noise starts. this only happens if the weather is colder than -10 C (14 F) (i can't blame the car as my bones squeak when it's colder than-10 ) This is definitely an expansion/contraction issue.
The dealer indicated that they will have to remove the dashboard to fix the problem and recommended that I wait towards the end of the warranty, observe other issues and fix all at once as multiple removal of the dashboard may bring new problems (i.e. snapped pieces may get loose).

With the temps at a all time low in the U.S. this week, my TPMS warning light has come on in my 2012 RX350. It will stay very cold for most of the week, so is it ok to drive with my warning light on.
I don't want to check my psi in the tires with a tire gauge because I was told a valve stem can freeze open in extreme cold letting the tire to go completely flat.

I have a 2012 RX350 with about 25k miles. Remote FOB will not start the car. Strange problem that I cannot find anywhere. The batteries were replaced in both FOBs because they were showing 2.6v. Still will not start.
Pressing LOCK, LOCK, HOLD LOCK you can hear the click of the doors locking but the flashers do not flash. After holding lock for the 3 seconds the flashers will flash 4 times, then nothing. All other functions of the fob work correctly.
I was thinking about removing the car battery for awhile (kind or a reboot, maybe) before bringing to dealer (110 miles away).

There's a thread similar to this on the front page, but I wouldn't exactly describe my issue as a "rattle".
I've got a good video of the sound it's making here : [URL] .....
It's definitely much louder with the hood up--doesn't seem quite as drastic when sitting in the driver's seat.
I've come across the thread here on the engine rattle/knock fix, but I'm not sure if this is the same thing. Would this be considered a knock?
It's a 2011 Elantra with about 82,000 miles on the odometer. It has an extended warranty on it, in addition to the 100,000 mile powertrain warranty on it, so it's at the dealership this morning.

We have had a few mornings (in garage) where it would seem to not really id say a knock but maybe a clicking sound and it would quit right away. This morning that did not happen so i shut the car off and checked oil it was low.
Got under the car and can not see any leaking no oil on ground. So i had a QT i put in and that seems to quiet it after a few seconds.
I called local TOY dealer and they said its common for 2010 to use some oil and not much they can do. I thought what is a little it was at the end of the dipstick.
They said they can only fill it up and then have me come back in 1400 miles and see how much is used.

So this is the second winter I've had my GX (a 2014 purchased in Nov. 2013).
With radio and other accessories turned off, there is a rattling/grating sound that is quite pronounced at/near idle, especially when cold. Sounds like a rapid PRAPP-PRAPP-PRAPP. This occurs when the vehicle is in Drive, but stopped. Occurs most often at within the first 5 minutes of operation....i.e. leaving the house or office, driving to the end of the street, hearing it at a stoplight or stopsign.
I've posted videos/recordings of it previously, which I have also shown to the dealer. The dealer said they could sort of reproduce, but could not diagnose it. I have tried to crane myself outside of the GX to listen to it, but from outside nothing seems to be amiss.
At first I was worried that it was engine knock/the car eating itself, but if that noise was representative of that, I think the car would be blowing smoke or dead by now. I have not noticed smoke, adverse effect on fuel economy or the noise at speed/under load, as you would expect if the engine were truly knocking. So I'm thinking it may be a fan, some type of underhood accessory, etc. that is the culprit. Sounds almost like a plastic component (fan, pulley, etc.) could be off kilter?? Something that more or less goes away after the engine has fully warmed up and the car has been driven for 10 mins or so.

I am very puzzled with my new 2015 Lexus RX 350 , I parked my car at the gas station and suddenly noticed that I dont have my key on me and couldnt find it inside the car anywhere. I thought I dropped it somewhere outside but to my surprise when I tried starting my car it started fine assuming the key was some where close by.
I tried stepping out and to lock the car and got a message the key is inside the vehicle so car wont lock. I was able to start the car and drive it home about an hour drive car never complained about key not detected message. I called the dealership and they told me car will keep running if you drop the key outside while the car is running but after 15 mins of driving it will give a message key not detected.
I am locking the car now using the second remote but its risky to have the car in such a condition as any one can drive it away if they open the lock somehow. I have looked every where under the seat, in between the centre console and seat, under the seats key no where to be found. Could it be possible that key was dropped outside and the car is malfunctioning that its allowing me to start it and drive it without complaining.

Recently when starting RX350 the check engine light and Check AWD lights went on. Driving the car for a short distance it idled very roughly and had no power (could not exceed 50mph). Drove home, shut car off, and restarted within 5 minutes. All lights went out, and car performed well. No problems since....what could have caused this problem?

I am getting a strange chirping sound from the engine (during idle) on my 7 month old RX350..Is this pretty common ... experienced a strange howling engine sound when you accelerate the car( E.g. when you are going at 30 mph and want to speed to 60 mph), I can hear this when I turn off all the noise (radio) and drive on a quiet street...
