Lexus GS 2006-11 :: 2007 - Clunk Noise When Brakes Are Pressed Or Accelerate?
Aug 26, 2014
I just bought a 2007 GS350 that had 45k miles and have noticed something strange with I believe the transmission. So far I have has 2 times when I have hit the brakes hard and had to accelerate again and either heard a clunk noise or even had the tires burp once after the clunk. Tonight I hit the brakes hard to avoid a red light and heard a clunk. I'm going to get it checked out at the dealer but I bet they will tell me they can't reproduce the problem. I have 2 other Lexus's (IS300) and have had no problems so this is a first.

2007 GS 350. In the past 6 months i have changed my FRONT brake pads with two different pair. First was a generic pad(REMOVED), and did some research then went for Akebono(CURRENTLY) brake pads 2-months noise-free and now back to braking noise dilemma.
Issues:
-In the morning, first 3-5 pressed brakes makes loud(REALLY LOUD!) humming noise then goes away. Feels like the brakes are rusty but it continually does it everyday. I just got the car serviced so assuming all my fluids are filled.
-Randomly, on a fully stopped brake i hear a whistle noise from the front brake. NOT as loud described above.
-I noticed the noise happened the most on HOT weather, and occasionally on COLD weather.
Longo Lexus advice me to buy an OEM brake pads and should resolve this problem. I'm also thinking of just getting it done at the dealership and pay that extra cash plus warranty.

I just had my front brake pads replaced by a local shop. I am now hearing a clunking noise every time I step on the brakes. I got the brake pads from the local Lexus Dealership but had them installed by a local shop. Is it normal to have this clunking for the first couple hundred miles until the brakes "wear" in or do I need to have someone else look at the brakes?

My RX350 is a 2007. Recently replaced the two front struts and noticed the passenger side is exhibiting this peculiar clunking/clicking/popping sound when turning. It mostly happens when turning in motion but once in a while when parked. Clunk/click sound usually only occurs once, or in a short series of 2-3 times, during turning.
Video of this clunk/click while parked : [URL] ....
Noise is almost silent at the strut mount/bearing, so I suspect it's lower in the assembly. Can feel the clunk/pop vibration with hand placed on the lower spring seat.
Took the tire off and thoroughly inspected things. No tears/leaks in any joint sleeves/bushings. Tie rods and CV joint look fine, as do strut mount, bearing, upper spring seat, insulator, rubber bumper, sleeve, and spring. None of these were replaced during the strut replacement as everything looked great and with only 55k miles.
I've not been able to reproduce the issue with the engine off, nor when the tire is off the ground when jacked/lifted.
During Google searches, it was suggested the culprit is likely either the strut mount/bearing or CV joint. We removed the strut today and everything looks the same as during the install. We can't reproduce the sound with just moving the knuckle around with the strut removed. Strut mount/bearings look in excellent condition.

I have Toyota Prius 2006 with about 58k miles. For the last 12-16 months I encounter the following problem: when I press brakes, I hear knocking noise. It doesn't happen every time, but when it does it only happens when I press the brakes. Once I brought my car to a Toyota dealer and waited for an hour until my car was taken for a service. Mechanic found no noise. I tried to produce this noise but my car didn't want to cooperate. I don't see any messages on a display screen. It happens with power on/off and pressed brakes. What the knock is and how to get rid of it?

New LS 460 owner (2010 swb). Owned the car for two months now and started hearing a clunk noise from the rear when the car accelerates very slowly. Showed it to the dealer and they could not replicate.
Also hearing a water rustling noise from the right side (appears to be coming from the passenger door); again, this occurs only when the car is accelerating gently from rest.

I have a 2006 Sonata LX with 91,000 ,miles and today it starting making a clunk sound when I would accelerate normally as it was going from 2nd to 3rd gear. My question is this: I have 91,000 miles on it and have owned since new in 2005 (8 years). Does it sound like a transmission problem and would a transmission problem be covered under the 10 year, 100,000 miles warranty?

I have a 2007 Sonata Ltd (63000 miles) and had a clunk in the front suspension. I had the front upper control arms replaced (which were visually badly worn) and that fixed the problem. But now, a several months later another similar clunking noise has developed when I go over those small speed bumps in parking lots.

when i am stopped and turn my steering wheel a lot to either left or right, and i accelerate, there is a loud thumping hammering noise coming from the front of the car.
it also happens when i am turned a lot to the left or right, and i reverse. it sounds like a hammer hitting cement. it only happens when i turn almost all the way to the left or right...?

Today was the second time I have walked into the garage and heard my Prius making a weird noise. It's not the noise that comes from the front when you open the door or press the brakes....It's coming from the rear of the car. It stops when I press the start button. I made a video of the noise (nothing to see, as it was dark in the garage, but you can hear the noise.
My concern is that it's something running that will wear down my battery if I happen to not notice it is doing it sometime in the future.

Few weeks ago I bought my first Lexus, an '07 GX 470. It has roughly 75,000 miles on it, 2 previous owners before me. Anyway, I hear a noise sometimes which either sounds like a slight belt slip or fuel being pumped into the injectors when I give it a good amount of gas and the engine downshifts to accelerate. I had the dealer replace the drive belt(serpentine belt) because of 2 reasons, it needed to be replaced and I thought that could be the problem(I did not have to pay for it since I have had some problems with the Lexus dealership I bought it from, they did it as a "goodwill" gesture, that's a story for another thread) and inspect the tensioner and pulleys, they said the pulleys and tensioner were in good working order.
I drove the GX home tonight after said replacement, and I still noticed the same noise. The best I can describe it is like I said above, a slight belt slipping noise or it could also be described I guess as fuel being injected under acceleration as soon as the trans downshifts to accelerate. I am just curious if this is normal for this engine or do I have a possible problem? It's covered under the Lexus used car warranty for another 5 months so if there is something wrong, obviously I would like it fixed under warranty if something is wrong. One thing I should probably mention is, the noise is semi quiet and I guess the average person might not even notice it.

I just purchased a used 2007 Lexus GS 350 AWD. I had it inspected and there were some minor problems (air filter, small oil issue) but nothing big. Driving it, I've noticed that the wheel shakes a little bit when applying brakes and based on my google searches, it's likely a rotor problem. I've literally only driven the car less than 100 miles since it was inspected. Does the inspection place (Tires Plus) bear any responsibility for clearing the inspection on the car? Should I take the car to Tires Plus to look at or should I take it somewhere else?

So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.
I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.

The other day I had my windows open while backing up and noticed that the brakes make a clicking noise when I initially apply them while in reverse.
This happens every time I'm in reverse and I apply the brakes.
The clicking is only when I first step on the brake, but it happens every time I first step on the brake in reverse.
Maybe this is unique to the LS600hL (2008)? Are brakes on my LS different from brakes on LS460 / LS460L?

Driving my 2008 460L and I get the brake sensor warning. Ok I've been through this before and know I have a little time left, but two days later I get a little grind noise. Then suddenly metal on metal what the hell is that noise! Turns out the passenger side rear lost a pad... it's just gone. The plate is left but the pad is gone on the inside of the rotor. The outside still had about 25% left. The other back wheel still had about 25% left on both pads.
I have 97k on the car and the rotor was turned on the last brake job so I assume I am done with this rotor and order a new one. Now the fun... I pull off the caliper and compress the cylinder on the offending pad first. The way I do this is with a big pair of channel locks I put one jaw on the pad and one on the back of the caliper and squeeze. It works a treat so I pull the offending pad and the dust boot falls to the ground in pieces. Great... now I put the channel locks on the other pad and when I squeeze, it goes in very easily with almost no resistance and the cylinder on the other side(with no boot on it) shoots out along with a bunch of fluid, probably 4-6 oz.
I decide to reassemble everything knowing I now need to bleed the brakes. All of the other wheels are normal and the brake job goes smoothly.
Frustrating part is here... how do you bleed the brakes in this car?!
methods I tried:Gravity - open the bleeder valve and let it drip, the dripping stopped after 20 minutes leaving no fluid in the line or caliper at all.
vacuum - I used the hand pump tool to try and pull fluid thru, got little spits and dribbles at best.
traditional - had my son pump the brakes, he could get a spongy pedal that bottomed out but never a firm pedal and the cylinder remained empty.
pump and suck - aggressive pumping of the pedal with the suction device on the hardline nipple. This resulted in a little fluid coming thru but no where near the amount you'd expect.
Now I have VSC, Brake Malfunction, ABS warning on the computer.

I have a grinding noise coming from what I believe are the front brakes. It happens when I apply the brakes and sounds like the brake pad is worn out and there's metal-on-metal contact but when I checked the pads, they are at 80-90% (rears have about the same amount left). I hear it the loudest just before coming to a full stop, from about 20 mph down to stop. I thought it was caused by rust on the brakes but after I wore off the rust, the sound is still there.

when i initially purchased "used " my 08 gs350 i had a problem with brake squeal. I kept taking it in to the dealer until they ended up changing front rotors , all 4 pads , and new shims .
Took my car into my usual mechanic to get an oil change. I knew i needed brake pads and he changed all four pads out for $350 .I am having a terrible time with brake squeal now. the mechanic is telling me that i have warped rotors and need to replace all four. He is telling me that he wont charge me labor, but the parts will cost $400.00 I goggled the cost of the parts and he isnt far off on the price . My concern is that his fix isnt the correct fix. Front what i can tell its the front rotors making all the racket.
What should i do ??I dont know if they re-installed the shims and have no idea what kind of pads were used . Thinking about taking it to the dealership and being done with it .

I had my window down as I was backing the car into the garage today and heard a metallic clicking noise from the rear as I tapped on the brakes. The noise only happens when I am in reverse. When I put it in drive and move forward there is no clicking noise. As an AZ resident its rare for us to have the windows down so to be honest I cant really say how long this has been going on for. My car was just in for service for oil , tire balance, and alignment this saturday

When I apply the brakes on and off while in park, I hear a "fluttering squeaking" noise. I examined the brake pads and calipers, and everything seems to be fine. I greased up all the brake hardware and no luck.
Also, I have a popping noise while making turns while I am not braking. I really doubt there is any connection with the brakes? I recently went testing in a parking lot, and while slightly turning from left to right I noticed the popping constantly. Keep in mind no brakes were applied.
Last year the dealer replaced the brake actuator and all arms were replaced. BTW, I am past my extended 100K warranty!!

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.

I have a 2006 Lexus is350 that has the rather terrible high metallic oem brake pads. The rotors and pads are in great condition, however they produce the most horrific ear piercing screech that can be heard for miles and I've even had people get out of their cars at stop lights to tell me my brakes are really bad. Like I didn't know... So, I've been researching replacement parts while I suck up the fact that I'm probably going to be dropping hundreds of dollars on a cosmetic issue, but it's really so terrible I think I may have to break up with my car if I don't fix it soon.
I've pretty much decided on not skimping, because from all that I've read it seems that given the known issues with the IS line's brakes they really need high quality ceramic and low dust pads. I've been reading a lot of good things about ebc redstuff pads, as well as some good things about akebono premium pads. I also am really confused about what to look for in a rotor.
Lastly, should I do the replacement myself? I'm kind of a novice at diy car repair, in my old (86) volvo I did most of the maintenance and repair myself, but I never had to do brakes or any of the other big things. Just littler things like power steering fluid reservoir, throttle hose, water pump and a few other things. Would I be in over my head replacing my brakes myself? They are just so vital it freaks me out a little bit if I don't do it right things will go terribly for me...
