Lexus GS 2006-11 :: Single Knock Noise When Pushed On The Brakes
Recently, I changed the brakes on my 2006 Lexus GS300. Everything went real smooth with changing the front and back brakes.
When I took it for a test drive, I immediately noticed a SINGLE knock noise when I pushed on the brakes. Also, I noticed that sometimes when I got +50 mph, I'll hear the knocking noise in a repetitive fashion. If I gently apply pressure on the brakes, the knock noise stops. If I let go of the brake, the knock noise returns. It sounds like the knock noise is coming from the front-driver side area.
What the culprit could be? I've taken the wheel off a few times, took the brake pads off, put them back on, made sure the caliper screws were tight, etc.
Lexus GS 2006-11 :: Check Engine / VSC Lights On - P0333 Knock Sensor Code
I just purchased a 2006 GS300 AWD w/115k. Started car on lunch hour to find check engine / check VSC lights on. Ran codes to find P0333 Knock Sensor code. Vehicle seem to run perfectly fine, but now that the light is on, it is definity spark knocking under acceleration. This is my first Lexus / Toyota product, so I am unfamiliar with the common problems or fixes. Are knock sensor replacements common?

Lexus 3.3L RX-330 Engine Noise - Part 3 - YouTube
I am concerned with an engine noise.
5 months ago we bought a 2005 Lexus RX-330. It had 109k miles on it (now has 113k). There is a faint but noticeable engine tap/ knock/ tick coming from the engine. I think it has the 3.3l, 3gr-fe engine.
I have listed some observations:
The sound does not occur on startup, when the car is completely cold.
The sound starts after 5-10 minutes of driving or idling.
The sound diminishes and is almost imperceptible after another 10 minutes of driving.
The sound is only noticeable at idle.
The sound/tap seems to occur about 5 times a second at 600 rpm (idle)
The sound increases frequency with rising of rpm.
At approximately 2k rpm the sound cannot be heard.
If the vehicle is stopped after driving, allowed to sit for 5-10 minutes and then restarted, the sound will be loudest even though the engine is still hot.
The engine is quiet overall with exception of this sound. The fuel injector sound is the next loudest sound.
The sound doesn't seem to have gotten louder in the last 5 months but it may have gotten just slightly louder by my estimation.
I can hear the sound inside the vehicle and outside as well.
No other symptoms are present. I had the timing belt, water pump, idler and tensioner replaced as maintenance and as a possible solution to this problem right after buying the vehicle.
The mechanic heard the sound but told me he wasn't sure of the cause. He and I agree that it sounds like an internal engine noise. It is not a pulley, idler or exhaust sound. The mechanic told me not to worry about it and it was a normal sound. He also said to start troubleshooting would get expensive. I am still concerned.

I just bought the new pre-owned 2007 SC430. Very happy about the car performance but very frustrated in trying to set up my Samsung Note 2 with the Lexus Blue Tooth. I checked the Lexus website and found out they are not tested for compatibility. Besides, the voice commands did not work very well.
View 5 RepliesSonata NF (2006-10) :: Engine Knock And Check Engine Light Came On
I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.
It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.
I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?
Passat (B5) :: Engine Knock Noise When Engine Fully Warmed Up And In Drive Or Reverse
OK--2001.5 1.8t Tip, 85k, nothing but Mobil1 since day one religiously. At around 81k miles the t/belt tensioner seized & let the belt jump and bend a few valves. Had VW do the repair under the p.t. warranty. Engine now runs very well again except there is a knock noise that sounds an awful lot like a crank or rod bearing. The noise is worse with the engine fully warmed up and in drive or reverse. Took it back to VW, they said it's a bearing in the a/c compressor. Sounded like B.S. to me, since the noise is no different with or without the a/c on. I picked up the car & removed the a/c belt at home & found the noise was exactly the same. I've about had it with VW on this issue. Been back 3 times with the noise complaint, & the noise is getting worse!!

I have a 2006 Corolla LE with about 93,600 miles.
It was about 16 degrees Fahrenheit this morning and I drove on a cold start, and noticed the engine knock a bit when idling. Later noticed check engine light come on. After the car fully warmed up, 15 minutes later, the knocking seemed to subside.
I don't think I've replaced the spark plugs in the longest time, so could it be this issue?
Lexus GX 2010+ :: 2014 - Engine Knock When Cold
I finally made a recording (attached), I would suggest listening to it with headphones if possible. The noise I'm referring to is featured between the 0:28 and 1:00 marks. You can hear it again from about 1:10 to 1:25.
Just to recap:
2014 GX Premium pkg.
4400 miles
93 Octane always
The sequence of events is such:
1- Car is parked overnight in garage, air temperature is 60 degrees or less
2- Start car, pull out of garage
3- Put car in D
4- Drive to stop sign at end of street
5- The transmission downshifts and engine revs slightly as the car comes to a stop
6- After sitting at the stop for a few seconds, foot on brake, engine at idle, it starts to make that thumping/clunk noise
7- Noise stops once I start moving again, and does not come back once the engine is warmed up
Note: This happens whenever the temperature is 60 degrees or below and the engine is cold/car has been sitting overnight. All accessory systems were shut off for this recording/demonstration (no A/C or heat running, no radio or other accessories on).
Lexus LS 2007+ :: Engine Knock At Cold Startup
I recently bought a 2011 460 L, CPO with 28,350 miles. I love the looks and how it drives, smooth! But I do have a concern. Before I go to the dealer I thought I would educate myself from the experienced LS owners. I am hearing a very brief (1-2 seconds) mild engine knock at a cold startup.
This only occurs when the engine is cold and has sat overnight. It never happens after this first startup, even after turning the engine off and then on again. It kinda sounds like the oil isn't getting where it should be for a few seconds. Engine sounds great with normal and hard acceleration throughout the day. The dealership where I bought it is 300 miles away, so I would be taking it to a local dealership.
Now I did hear this noise and mentioned it to the service manager when I first bought the car, and the service manager told me that this cold startup sound is normal. He also mentioned the direct injectors at idle. I guess sometimes it's hard to fully trust what dealerships say. Is he right?
Lexus RX 2010-15 :: Engine Knock At Cold Startup - RX450H
It almost sounds like somebody is taking a small hammer and banging at the plastic cover on top the engine when the vehicle is started new from cold. After about 8 or 9 knocks it goes away.
Taking it to a dealer soon to get it checked.
2010 Model year. 81k miles.
Ford Super Duty (1999-2016) :: 2006 5.4L - Knock Noise At Start Up?
I have a 06 F250 with a 5.4L truck has 50k on it. I have been reading many articles on the issues with can phaser/cam tensions/cam chain issues. I have noticed that when I start the truck a get a knocking noise that goes away with in 5 sec of the truck starting. I have been noticing lateley if I am sitting still at a light and go to give it gas for a short period I get a sound that sounds like a cam chain slap for a split second as the truck starts to move it goes away. I had a friend of mine stand outside the truck and put in gear and power brake it and as it decelerates you hear a quick cam chain slap. I use Catrol 5-20w standard oil and motor craft oil filter. I purchased the truck with #6k on it 3 years ago I have replaced the leaking exhaust manifold with Gibson stainless unit and have confirmed they are not leaking again. I have heard that the hydrolic cam tensioners sometimes get clogged and people have run a oil additive to clean out clog.
View 14 RepliesLexus ES 2013+ :: Engine Knock When Accelerating From A Stop Or After A Brief Coasting On Freeway
I purchased a ES300h in March 2013. Starting end of September I noticed a rattle (pebbles in a tin can tumbling sound) when I went up a slight grade, accelerating from a stop, or accelerating after a brief coasting on the freeway. The first time at the dealer they said stop using Costco gas and use Top Tier. I used Shell and Chevron and there was a 80% improvement but the nuisance still continued, some days more and some days less, meaning when it rained it poured.
On the third visit to the dealer, with two specialists on a ride along of course it does not make that noise, but left it there for them to find the continued problem and they conceded it is engine knock to which there is nothing out of specs with the engine AND say that this is normal. I have never had a car do this, maybe specific to hybrids? The service advisor goes on to tell me that they filled my tank with 91 octane to stop the knock, BUT, the manual says use 87!!!
Some say this can lead to engine damage, some say only blown gasket, the dealer says no problem! A friend of mine has the same car and has no issues.
Toyota - Engines - Corolla :: 1999 - Engine Noise But Not A Knock?
I have a Toyota Corolla 99 that I have owned for a bit over 2 years; it has 97500 miles. After around 2,000 miles after an oil change it starts burning oil (no smoke or smell). I tried to check it often to make sure I am not running on empty. The last time I had to fill it up once and top off a bit another time before the oil change. I recently also changed the serpentine belt.
I thought the serpentine belt was the noise I was hearing when idling. Now, the noise is still there. Does not get worse when accelerating so hoping it is not a engine knock. Was told by Autozone guy that might be the iddle throttle. Hard to describe noise. No clank, almost like something spinning with a noise every 2 seconds.
LeSabre :: V6 With Automatic Transmission - Loud Knock Noise In Engine Area
1987 Buick LeSabre V6 w/automatic transmission. Suddenly getting a fairly loud "knock" from somewhere in the engine area. Only present at low rpm or idle, goes away at higher rpm's. Does not seem to be related to vehicle movement. "May" change some with gear shifting but can not really tell. Oil is full and no "idiot" light warning. Timing belt recently changed. Car seems to run fine, just making noise. Any clues???

So my wifes 07 93k miles started to make a strange knock rattle noise. It sounds like the knock some on here have when the water pump was going out. It only happens when the car is on, in gear ( drive or reverse) brake pressed And AC ON. The engine begins to vibrate under the load and the rattle begins. Sounds like you its coming from behind the alternator under the valve cover. Once I place it park.... or turn the AC off it goes away. It idles fine. Quiet And Smooth. But once I place it year it comes back!!
