Lexus GX 2004-09 :: GX470 - Noise Coming From Under Floorboard And Vibration In Brake Pedal
Jan 30, 2014
I have a 2004 GX470; bought it new. The last few months I have been hearing a strange noise from the driver's side; seems to be coming from under the floorboard and can sometimes feel a vibration in the brake pedal. The noise is similar to a cat meowing. Have a son who is a GM tech; he said it sounds more electrical than mechanical. It happens mostly when I drive it cold. Seems to also happen more when turning/braking. I had the main belt replaced this summer. Should I have the tension pully replaced?

We purchased the vehicle (2013 GX460) in September 2012, and had the car for 6 weeks before my wife was hit by an oncoming car who missed a stop sign. 8 weeks later and 23k of repairable damage to driver fender, front bumper, grille, hood, frame, and all components within those major areas, we received our vehicle.
The vehicle is wonderful and a joy to drive. When the brake pedal is depressed at low speeds (i.e., maneuvering in parking lot, entering driveway), there is a slight vibration to the pedal (similar to the vibration from a cell phone) and a noise that suggests an electric motor is working. The vibration is not like ABS; ABS is a profound vibration. The vibration we experience is very slight. The vibration is not apparent at highway speeds.
I do not recall either the vibration or the noise prior to the accident, and I suspect that this is a result from the accident or from the repairs. I have already brought the GX back to the dealer for this problem and they were quick to dismiss it, but I am really concerned that this is a real problem, and I want the dealer to re-assess.

I have a problem with my gauges. Sometimes my RPM gauge works, and sometimes it doesn't.
When I approach the car and open the door, I hear a weird noise coming from the gauge cluster (or a nearby area). When I start the car, none of my gauges work, and you can see the temperature, speed, and fuel gauges flickering. After about 10 or 15 seconds all gauges fire up, except for the RPM gauge.
The flickering does not always occur, but my RPM gauge is dead most of the time. It works once in a while in the morning when I start the car, but once I shut down the car and start it again, I loose my RPM gauge the rest of the day.
I think the noise I hear behind the cluster or inside the steering wheel area has something to do with this problem because the cluster problem arouse when I started hearing the noise.
I managed to put the problem on video, and you may see it here. If you focus your attention on the fuel and temperature gauges right after I start the car, you will see the flickering. You will then see the needles jump to their correct readings about 15 seconds after the car starts, but as you can see the RPM gauge is dead.

I just bought my first Lexus, picked up a 2008 GX 470 with only 35k miles!
I just had the TSB for the "Clunk" issue fixed and I had a tire sensor that was leaking and had that fixed.
The ONLY other issue I am having is that there is a vibration at between 1250-2000 RPM and it's most prevalent at 1500 RPM, but it is gone above 2000 RPM. This happens while in park and hitting the accelerator to get to those RPM and it happens in all gears while driving, which is especially annoying because the SUV typically is sitting right at 1500 RPM while driving.
The Lexus dealer thought the driveshaft TSB would take care of the vibration, but it didn't.

So for the past few weeks, i was getting this weird vibration coming from my brake pedal.. When I am about at 40 mph driving and braking or even when I am slowing down with out braking it vibrates.. I checked my wheel bearings.. I don't think that it.. since my steering wheel is not shaking when i brake, i think my rear rotors would be warped..
Also my idle is weird on my car.. I switched my coils and plugs.. it jumps.. really slightly and there is a big one.. when I opened my hood up there is this weird noise like a rattling noise and that is when the idle jumps up and down.. something like this [URL]....

So I changed out my front brakes and rotors on my 03 camry le, and I noticed the driver side pads are more worn out than the passenger side. Also when im driving highway and coming off I notice some vibration in the brake pedal, its not all the time though. Do you think my caliper is partially sticking? I can manually push the piston on the caliper piston using a clamp.

I just recently got 2008 gx470 as a college graduation present in May. Very exciting having a GX as my first "real" car!!
After driving a few months, I have noticed that my brakes are acting a little funny. Whenever I brake, the car seems to "skip" until I come to a complete stop. It's not a very serious problem, but more of an annoyance.
I took it to the dealership and they told me that my rotors are "warped" and need to be shaved down. They quoted me for 600-700 dollars for the fix...
I just hit 43k miles

Just purchased a 2003 GX470 with 160k and after the low brake fluid light came on I noticed the master cylinder had a leak. After removing the cover it appears the fluid has leaked for quite some time as the paint has started pealing from the frame. The brakes however appear to be working correctly. Upon purchase the front calipers were seized and I replaced both front calipers.
After having someone depress the brake pedal while I watched, the fluid leaks from the end of the master cylinder each time pedal is pressed in.
After doing some research it appears there is a rebuild kit for the master cylinder.

To all 2014 and 2015 GX 460 owners, does brake pedal have a slight modulation or vibration while press it. Feels like ABS but not as strong pumping action.
When I step on the brakes the first time feels normal and then I let go of the brakes, then I press it the second time that is when I feel a slight modulation or vibration of the brake pedal.

I have been reading some mixed reviews here in regards to the "CLUNK". I am referring to that feeling as if hit from behind shortly after coming to a stop. Some are saying it still exists in the 2005 while others are implying that it has been resolved.
Just to be perfectly clear.... Has experienced this "Clunk" in a 2005 GX?

Just bought this van used last fall. Had an occasion, a few months ago, to brake quite hard (to avoid hitting a bird in the road--yeah, I know...) and felt a clattering vibration/noise in my brake pedal. It's happened a few times since then. Is this a problem that needs to be looked at or a normal reaction to quick, hard braking? (Braking noise in 2008 Dodge Grand Caravan)

In my 2008 F150 with 108,000 miles, I am having a vibration in the brake pedal. When I am stopping or at a dead stop. I first thought it might be the rotors needing to be turned, but the vibration seems to go away when I turn off the a/c.

Having bought my 06 GX 470 only a few months ago, we're encountering 90-degree-plus days for the first time. There is an unusually loud noise from the engine that I'm almost sure is cooling fan noise. It occurs after running in the heat of the day. It's not mechanical noise, but a loud roar like that of a large truck engine. Is this typical for these models in the heat?

How to diagnose the engine issue I am having. The gx currently has 96k miles and I am planning on doing a timing belt and water pump replacement as I plan on keeping it as long as possible.
One new issue that crept up is that when going down the hill the car engine sounds like it's actually accelerating and the RPM drops to as if it was idling.
Normally when going down the hill it usually stays around 1 or 2 on the rpm, it's noticeably different and just started happening recently. What might be the cause of this?

06 GX470 muffler exhaling white smoke for a while, now the smoke disappeared, however, a new hissing engine noise is evident. The noise increases with the revolutions of the engine and it never stops.

Our 2004 GX has been a great car, but is suddenly doing a number of strange things - like not start. When I say it won't start, I mean you can turn the key, the dash lights up, the steering wheel adjusts, radio goes on, etc, but then NOTHING! No solenoid "click", no starter noise, NOTHING! Does not crank at all. The car just turned 60,000 miles, is in great shape, lives in the garage and has never been in an accident.
After the first couple of times it did this, had the battery replaced, as it was getting close. and then the car started again. Until the next day. No rhyme or reason as to when it would do this. It might start 10 times in a row, then NOT start for a while, then magically fire up instantly, even after several key turns. I wiggled the key, tried a different key, shifted to Neutral, wiggled the shifter to try to rule out security interlock, bad ignition switch and shift interlock. No dice.
Did some more research and thought it might be the starter relay - banged on it and it started, so replaced that part. Didn't solve the problem. It also began to randomly die while idling (in park, or in drive). Sometimes it would re-start, sometimes not. The times it has done this, it typically dies after running or 15-20 minutes, but NOT ALWAYS.... Sometimes it will die once, then be good for the rest of the day. Sometimes it re-starts immediately, after a few minutes, or more recently only after sitting for a few hours.. So basically we can't use the car.

I am original owner of a 2000 CRV, it's in really good shape and has been maintained by me on about 99% of all repairs it has 140k total. I have this thumping noise coming through the floorboard by my feet, under moderate acceleration and it goes away at just about any speed when you quit accelerating. Sounded like a bad halfshaft, I had already replaced one so I did the other side, got worse. So I replaced the one that had been in for just 2 years--no better. Asked the auto parts store for a recommendation and went to that shop, they balanced the tires, checked rotors and concluded I was buying junky rebuild half shafts. I had them replace the one they thought was bad with another rebuild, just as bad or worse...
I took home and put in both sides with new halfshafts, I also noticed some play in jackshaft bearing and replaced that as well....no better. Shop claims that a website they subscribe to says that 50% of aftermarket halfshafts for CRV are no good. But honestly we are 5 for 5 bad, last two were new from NAPA. Pulled things apart and checked wheel bearings left side was sticky so had machine shop press one into the knuckle, right side was done about 14 months ago. Also disconnected drive line and drove it as a 2 wheel drive vehicle....no better. Would a broken tire belt only make noise on acceleration or after a corner when you accelerate? Is this a possible indication of my transaxle going out? ---

New to my 2008 GX470. 100k miles. Love it so far. However I think I am hearing a intermittent rumbling as I drive down the road. It is like the rumble from a radio base sound. It could be normal road noise but I bet it is not.
I have replaced the left front axle (grease boot broken), replaced the rotors and pads, replaced all differential and transfer case fluids (not transmission yet) and inspected all the suspension parts.

2006 GX 470, purchased CPO with 26K miles in March 2008.....my sunroof just made a horrific clicking noise upon opening last night, and the one-touch opening isn't working, I have to physically hold the button down in order for it to open all the way.

Have water on passenger side floorboard after a heavy rain or car wash. Seems to come from more the dash glovebox area than rocker panel. I'm aware of cleaning sunroof drains, don't think that's it.
I've removed the kick panel, can see drain, it's not too short like other post show. I realize it could be the windshield, but what about the cowl drains?
Now to the clicking noise. I hear it when AC is on recirculate, if I switch to fresh air, it stops. The temp outside or in, seems irrelevant.
