Lexus RX 2004-09 :: RX330 - Faint Tap / Knock / Tick Noise Coming From Engine

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.

Lexus LS 2007+ :: Faint Clicking Noise At The Rear Of 2008 LS460

I have some FAINT clicking noise at the rear of the 08 LS460 and I'm thinking it's rear bearing going out..but not sure...what exactly does bearing failure sounds like? I hear this SOFT clicking noise from (more likely) the right rear. The noise is very faint and I have to roll down the window to actually hear it.

If I move through the neighborhood at about 15-20 mph, I hear this clicking faint clicking sounds..and if I speed up a little, the clicking noise increases (in frequency, not loudness). When I go faster like on freeway or normal road, I can't hear it anymore. Probably clicking too fast or not as loud at that speed. With windows up, I can't hear it at all.

Is this has to do with rear bearing going out on me or possibly something else? Any recommendation where I can start looking at? Is it brake pads? The car is 35K miles but since it's 08, unfortunately it's out of basic warranty (time). Is this covered under powertrain?

Prius (2004-09) :: Faint Clicking Sound While Braking That Varies With Speed

I have determined that I most likely have a bad CV joint - a faint clicking sound while braking that varies with speed that happens with the car in drive, but not in neutral.

I've also found instructions here on how to remove/replace the axle, but I'm wondering if it can be done without separating the tie rod end and removing the ball joint. On other cars I've managed to do this by unbolting the strut, which allowed the hub assembly to flop out enough to be able to slide the axle out of it. Is this possible on the Prius? I have to replace my struts anyway so I was hoping to do it all at once and avoid dealing with potentially frozen suspension components.

Lexus RX 2004-09 :: RX330 A/C Does Not Keep The Cabin Cool

I have a 2005 RX 330 with about 100k on it. The A/C does not keep the cabin cool. If you turn the fan up it will keep it cooler. I took it back to the dealer and they say there is nothing wrong with it. They did recharge it but it did nothing. You have to keep the fan turned up to just stay comfortable. I have had service loaners and I have to keep turning the temp up or it gets too cold.

Lexus RX 2004-09 :: 2006 RX330 AWD - Bad O2 Sensor

I have a 2006 RX330 AWD. I took it to get inspected and was told I had a bad O2 Sensor.

Are they easy to replace? What should the average cost be? I was also looking for the part number. I was told that "Bank 2 Sensor 1" failed. I was looking for the part but I am not sure I found the correct part.

I was also told that the front inner and outer Tie Rod needs replaced along with both rear wheel bearings. I found the parts for the tie rod but not sure about the rear wheel bearings. Wondering if i need to get just the wheel bearing or if i need the wheel bearing and hub assembly also.

Lexus RX 2004-09 :: 2006 RX330 AC Never Gets Really Cold

It seems like my wife's 2006 RX330 does not get as cold as it used to. At times, it will even blow warm and humid air, even though it is set to max cold, although this is intermittent, which to me, creates a harder problem to diagnose.

For example, if I put the AC on Auto, at 70 degrees, it never gets cold enough for the fan to drop below the Medium fan setting. To me 70, is not that cold, and it should be able to reach this temperature, and then slow the fan down to just maintain the temperature. I can even put the system on Max AC, and it the fan blows at the High setting, but it never gets really cold.

Lexus RX 2004-09 :: RX330 - High Pitched Hum Once The Car Reaches 30 Mph

My 2005 RX330 has run fine for all 45000 miles to date. One exception is that there is a high pitched hum that becomes noticeable once the car reaches 30 mph and continues to increase pitch until about 45mph. The hum seems to disappear when going faster than 45. If you cruise on a quiet street at 30mph the hum will stay steady if you maintain speed. The hum will increase if you accelerate.

But... if you take your foot off the gas pedal the hum instantly stops. Put your foot back on the pedal and it instantly starts. You can almost "play a song" by taking your foot off and on the pedal. Lexus service clearly heard the sound during a test drive, but could not figure it out.

Lexus RX 2004-09 :: RX330 ABS Light On At Very Low Speed Or Just Stopping The Car

Hard to fix? Only happens when going under 5 mph either in slow traffic or slowing down to park in parking spot or just stopping the car. Doesn't happen at high speeds. It's like I'm driving on snow or ice or wet pavement but there is dry pavement. Brake pads and rotors were cleaned with no success. Guessing that a sensor is dirty or broken or such.

Lexus RX 2004-09 :: RX330 SRS Warning Light Stays On - DTC 23

I have a 2004 RX330 that all of a sudden had the SRS warning light come on as well as the passenger airbag OFF light being constantly lit up even when someone is sitting in the passenger seat. I put the SRS system in diagnostics mode with a jumper clip to determine I am receiving a DTC of 23. Documentation I have found for this online states for Lexus it is a occupancy classification system issue which I know means it's something on the passenger side.

This seems like it would be related to the occupant seat sensor itself which I am first of all wondering if it is bypassed like the BMW guys have done on their cars when this issue happens.

Secondly, I'm wondering with this specific code of 23 could it be anything other than the seat/weight sensor? My passenger seat belt has tons of slack and doesn't retract as it should so I'm thinking maybe pre-tensioner sensor but not sure because it also seems to stick when trying to unbuckle it as well which leads me to believe it could be the fastener sensor.

I feel very unsafe having any passengers in the vehicle right now and the car is well beyond its warranty of course so bringing it in to the dealer is really a last resort option for me since I know at minimum they'll charge $1000 for SRS wiring issues based on what I've read.

Lexus RX 2004-09 :: Right Side Speakers Not Working On 2005 RX330

Installed Kenwood DDX7701HD unit and I have lost right side speakers. Used Metra Axxess TYTO-1 harness along with ASWC-1. Also had bad battery cell and replaced battery. I get plenty of sound from drivers area but when I adjust balance to right there is no sound at all there. At this point my ASWC-1 cycles through but isn't recognizing radio. That issue can wait unless it is part of this issue.

Lexus RX 2004-09 :: Converting RX330 Power Steering To Be Electric?

So, I'm thinking of converting my RX330 power steering to be all electric, based on the RX 400h power steering system. I know the 400h operates the power steering on a 30V - 50V circuit but I need the wiring diagram of the 400h power steering circuit to know what additional components I'll need to do the conversion.

Question: Why am I doing this?
Answer: Save on fuel economy and power steering maintenance.
