Lexus RX 2004-09 :: RX330 - Faint Tap / Knock / Tick Noise Coming From Engine
Feb 27, 2015
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.

Knock or tick at 1000 rpm. Truck has 20000 miles on it. Dealer replaced cam phasers. What next?

I have a 2005 RX330, 90k miles on it. It's been running fine until last night.
Out to dinner last night, when I go back to the car, I turn the ignition key and get nothing.
So the car doesn't crank at all. No clicking either. There's a faint hum. All lights, radio, power windows, seat work. I tested the battery and it came in at 12.48v.
I'm thinking maybe the starter. But since it's a pia to get to it, i wanted to see if I should be checking something else first before i invest the time getting to it.

I have been experiencing a slight issue with my 07 Sonata V6 lately. When I am accelerating, most commonly when already at speed around 80 to 90 km/h, I would hear this 2-3 ticks / clicks when I press lightly or moderately on the accelerator pedal. The car would accelerate fine without any further noises. When I release the pedal, the car slows down a bit, and I press on the pedal again, then the same sound re-appears.

My RX 330 has 246,000 miles and just started making a squeaking noise in reverse only when cold. I was told it may be one of the CV joints and the only remedy is to replace the driveshaft.
Had to replace a driveshaft? Are there any aftermarket driveshafts for this model?

I have an 05 RX330 with about 120K on it. I've had it for about a year - no real issues. The car has a slight rattle coming from the engine compartment on the driver side on acceleration. From what I have been reading, that noise is normal on these cars. What I don't find normal is that it has an intermittent loud growl on quick acceleration from a complete stop. It sounds like the exhaust of a muscle car from the 60s, like Toretto's car in the Fast and the Furious.
It happens like at 2500 RPMs for a few seconds then it goes away. The noise is in the same area. It's driving me nuts. And just like everything, whenever I take it in to the shop to have it checked out - it does not make the noise. So far it has happened twice. Last week and last night. I'm afraid it be the transmission, but no check engine light, no loss of power, and the transmission shifts normal. I'm thinking it's an exhaust leak, but as mentioned before - no check engine light. If there was an exhaust leak I would imagine it would trigger an emissions code.

Just noticed this last week when I was driving around at slow speeds with my windows down. If I turn either left or right I can hear a faint little tick or creak for a split second. I can usually make it constantly do it if I swerve back and forth at slow speeds. Sometimes it happens when I hit a little bump as well. It makes me think it has something to do with with either the suspension or maybe some part of the steering components. Little things like this on a new car just annoy me. I don't really feel like taking it in to a dealer because I can almost guarantee they will come back with the typical "couldn't replicate noise" response.

I have a 2006, RX 330 with approximately 130,000 miles. I was driving up a hill today and my engine seemed to stall. I pumped the throttle a couple of times and it seamed to take care of the problem. I am thinking it is a dirty fuel filter. Would a pressure test on the fuel line give me the answer ? And yes I did check and there is plenty of fuel in the tank.

where best place to start looking for what's causing p0442 code on my 2005 rx330? and its not the gas cap... also have a "c" code identified for the VSC light, states that its wheel speed sensor. evidently wrote the wrong code down, i had it listed as a c1290 but in looking them up i couldn't find that one.

I bought my 2004 RX 330 last year with 110k miles. It starts up every time with no problem, except that It takes a few more seconds to turn over the engine till it starts. I have to keep the key turned longer that my other cars where all I need to do is just turn to start for a second only. I just replaced the battery and that did not change anything.
Is this normal for my RX 330, could I need new spark plugs? It's never been a problem in winter or summer.

2004 Jeep Grand Cherokee V8 4.7 L. Clock from right side of engine immediately after starting engine. Seems to be in rhythm with engine and increases in frequency as I rev. Gradually subsides over first 5 minutes and not audible after that. Recent small leak of transmission fluid, but I'm thinking that has nothing to do with this.

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

I have an 04 rx 330 with air suspension. The swaybar end links have just been replaced on the front and a rattling noise persists.
The noise happens over large and small bumps at high and low speeds at normal and low vehicle height. When the height is at "HI" the noise is louder and it feels as though the front end is shaking loose over bumps at 10 km/h+.
I took it in and was advised to replace the end links, they did so and returned it claiming the noise was gone. The air compressor and struts are in working condition.
I have done a search through the forum, not extensive... I was wondering which other components come loose/wear and cause a clunk/rattle/shudder noise.
Also, tires are new and at approx. 32-34 psi.

I have a rear wheel bearing type of noise that appears to come from the rear. My vehicle is front wheel drive and has 135K miles.
I checked the rear wheel bearing/hub assys on both sides and they had no play but I changed them anyway. Noise did not change at all. Rear tires have normal wear, no cupping or anything. Noise gets louder with increasing speed up to a point and then remains a constant level.
My next thought is to check the front wheel bearings/cv joints.

I'm hearing a sort of faint rotating squeaking noise coming from the front of the engine; I can only assume that it's something with the belts. Nothing too pronounce cause I just notice it yesterday, anyway I was hoping I get another take on what this might be before I take it to the mechanic tomorrow.

My wife's RX is really starting to give me a headache. The first problem I'm having with this car is detonation. The car starts pinging at part/ light throttle once the engine is fully warmed up. The is no CEL or codes pending. After scanning the car it seems that fueling is right where it should be and nothing else seems out of order. The pinging stops when you hit the gas harder. So far the only way to rid the car of this problem is to fill with 93 octane and that gets expensive with a daily driver. Shouldn't the knock sensors be handling this? Is there a way to test them?
The second problem I have is the heat won't turn off. Hot air always comes out at what seems to be low fan. I can move the area it comes from ( dash vent, floor etc) but I can't turn it off. With the fan set to off and no settings chosen I still get heat.
The car currently has 78k miles on it

I just recently started driving... with a second hand hyundai accent. Whenever i stop at traffic light with engine on, i hear tick tick noise (probs from engine?). it seems to be coming from front of the driver seat. When I start at the beginning, I do not hear any noise and also when i am driving i do not hear any noise or lets say nothing audible like this. Its only when i stop my car and while i am waiting, i hear this tick tick noise(very clear and audible).
Is it engine metallic part making sound when cooling down? When I start my car I see symbol for low oil pressure, batter life, check engine, but as soon the engine starts these symbol disappear which I think is normal behaviour.

Our 07 RX350 has 47,000 miles and I just starting to hear (I think from the front) a faint rattling noise while driving. It's hard to describe but it sort of sounds like what you might expect if an empty plastic bottle was slowly bumping around in a plastic box. It is not a metal on metal type of noise. The shocks/struts appears to pass the old bounce test and the car does not seem to display any of the handling issues you get when you have worn shocks/struts.
I also checked the upper engine compartment to see if any plastic shrouds or covers were loose - they weren't.

I have a 1996 Ram with the V10 that only has 10,000 miles since it was replaced by Dodge. 7 years has passed since that shortblock warranty job. It now has a tick/knock that I cant seem to locate? I changed the lifters and one push rod since is was a little bent and put it all back together. Still getting the same thing - nothing has changed ...

I have a 2000 F-150 xlt off road with a 5.4. I have owned the truck since 2001. The truck has 170K miles on it and I change the oil between 3-4K miles. The last couple oil changes I have I have noticed I haven't been draining as much out as I usually do, this past oil change was about 3 quarts low. I thought it was very odd. The truck runs great and does not smoke or leak oil.
This morning I got in and noticed a tick or slight knock, thought maybe it needed warmed up. After a minute. I shut it off and checked the oil, to my surprise there was next to no in the engine! This has me very worried now. I haven't checked my coolant since last oil change so I'm not sure if that's where it's going. Where to start looking, I'm missing like 5 quarts of oil in 3300 miles. Again the truck run great and does not smoke at all. I was getting ready to change it this weekend, always run high millage 5w-30.

When I start my 2013 Prius (the car just passed the 1000 mileage marker) cold, I notice a tick coming from the ICE that almost sounds like a lifter tick. I do remember reading somewhere (I've read so much Prius literature in the past couple of weeks, I could begin to guess where) that the car, when cold, fires after DTC. I noticed this twice now, once when the car had about 500 miles on it, and again this morning, though I'm sure this is occurring each time I start it cold. Is this noise typical or is this something I should bring to the dealership's attention?
