Lexus RX 2004-09 :: Loud Growling Noise On Quick Acceleration On RX330?
Jun 22, 2015
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.

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?

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 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.

Continuous noise. woooooWOOOOOO. I have a problem with my '05 Escape 4wd. 110k mileage, the sound started with 4 new tire installation a month ago. I thought it was tire noise since I had bought a different tread design, we replaced the brakes too. The sound is getting louder. Louder with acceleration, when on curve it increases.

When accelerating quickly with v10 get a noise like that of speed bumps on side of highway(bumpy humming) for a split second and then goes away. No change in performance but just had 2 new rears put on and alignment done.

AC compressor makes a loud growling noise and lugs the engine briefly when engaged at idle and the truck has been sitting for weeks. After that initial grind, it works perfectly and makes no harsh noises. Can I replace the compressor bearing or should I swap out the entire compressor?

So 2 weeks ago I noticed that after 30 minutes of driving on the highway my steering wheel started making a loud growling noise and vibrating really hard! When I hit the brakes it got worse but got better as I slowed to 30 mph. It doesn't happen all the time and not right away, only after a while of driving and the dealership says without codes they can do nothing...

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.

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.

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.

Something weird started happening post my oil change yesterday. AC is working only at LO temp and it blows hot air even at 65. AC light stays on but it starts blowing hot air at any other setting then LO..

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.

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.

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.

I've recently experienced a rattling(vibration)/growling noise around the engine when the car is running with the AC on. The sound gets louder when I put the car in drive and it goes away when I turn the AC off. The sound seems to be coming from underneath or next to the engine(right of engine when sitting in the car/left of engine when standing over the hood facing the engine)
I took it to Lexus and they told me its likely the water pump. The car drives great and I'm not noticing any leaks(water or otherwise) underneath the car. I had to park the car for 6 weeks while on a military exercise, and don't recall hearing the noise before going away. could 6 weeks of inactivity on the engine have anything to do with this?

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.

I have read that cleaning or replacing the switch that adjusts the outside rear view mirror's will get rid of the erratic operation of these. Mine sometimes works and sometimes doesn't. How do I get the switch out of that panel? It doesn't look like the panel will pop out from the front.
