Lexus GX 2004-09 :: Odd Clunk Feel Like Car Was Hit From Behind At A Low Speed Collision
Oct 27, 2011
I got a TSB done on my clunk about a year ago. The old clunk felt like the car was hit from behind at a low speed collision (I have the experience). But now the car has developed a different type of clunk. Now it feels like something is hitting me from directly below my feet. I can actually feel the vibration right between the sit and pedals. What gives now? Is it the same thing, anything to worry about?

Problem is noise that you can describe as clunk, not any harsh or sharp sound. It appears on road bumps or unevenness during slow speed up to about 40kph/25mph. The noise has not been heard over that speed even in bad bumpy roads.
List of thing I've done so far:
- Driven with empty rear compartments
- Driven with open rear door
- Checked the tightness of spare tyre
- Replaced rear stabilizer bar linkages
- Replaced rear stabilizer bar bushings
- Replaced rear axle carrier knuckle bushings
Could it be possible not coming from rear? Should I sit in the cargo space while somebody else driving, any success with this? What to do next?

I recently bought a CPO 2007 GX 470 with 110k miles. At no charge dealer made repairs re the Bulletin about clunk in rear when I slowly drive over speed bumps. Had all front and rear shocks raced with OEM shocks, and four new Michellin MS2 tires installed. Rear end still feels like is is bottoming out sometimes during regular local and freeway driving when going over different times of road bumps.
My 'i89 a Dodge Ramdharger ( only car I ever bought brand new off the lot ) with 174k miles and old shocks and original springs drives better over bumps and speed bumps than the GX. One Lexus dealer said the reason is because the rear air bags ( that are not leaking )do not fill up fast enough when going move bumps and that can cause the bottoming out feeling. My mechanic is going to check it over again. What could be causing the bottoming out feeling?

Yesterday I was on the highway - dry surface, a little bit of wind, but not much. While driving I kept feeling *kind of* like the Tiguan was getting pushed around by the wind, but not really. I looked at the trees, at the other cars and trucks on the road and none of them seemed to be moving around like me.
It was "kind of" like getting pushed by the wind - but actually more like the car was "crabbing" ... like the wheels were not spinning at the same speed. Very similar to the way it feels on snow/slippery conditions when traction control kicks in and straigtens out the Tiguan. It was like the front was fighting the rear and the car was twisting.
I chalked it up to being windy, although I've been in the Tiguan before in windy conditions and this was not the same.
Then today, I was leaving Home Depot. I closed the door, started the Tiguan, foot on brake and put the car in drive. Then immediately I had 4 tap-tap-tap-tap. Very much like if someone was pulling into the spot behind me and tapped me with their bumper.
I spun around in the seat and no one was in the car behind me, plus I have the trailer hitch in, so it would be a different feeling.
hhmmm ... very odd. I put the car back in park, back to drive and no tap.
Now I am curious. I turn the car off, wait a second, start the car again, back to drive, and sure enough another tap.
This is not the engagement of the transmission, this is a harder tap that happens after the transmission engages.
Tried it another couple of times and can replicate it.
I have to drive by the exit where my VW dealer is to get back home, so I stop by *HOPING* that I could replicate it again to the service manager, and sure enough - close the door, start the Tiguan, foot on brake and put the car in drive. Transmission engages, then immediately tap-tap-tap-tap
"hhmm that's not right he says". It was too late to get it into the shop tonight, but I left it overnight. Given my odd driving experience yesterday and the tap-tap-tap today, he was not sure if it was a safety issue with continuing to drive it.
This is a 2012 Tiguan SE 4 motion

Towing with my 07 F150. I now have a noise all of a sudden. I worry that is the rear end going out. As I accelerate normal from a stop, I , for one feel bump-clunk sensation, as if I have a bad u joint. 2nd I now have a "whip whip whip" whirring sound, sound character speeds up as I speed up.
I hope the sound is the brakes, because I know they are getting down to the end of their life.

I'm close to purchasing a 2014 RX 450h and thought I wanted PCS, but am not sure about the false positives. For all of you that have PCS, do you get false positives causing alarms and braking to happen for no reason? I ask because I am probably going to special order one and am debating on adding this feature or not.
On a quick side note - it appears that the automatic braking will happen on all RX's except for the RXh AWD. Why not? I don't know, and Lexus people couldn't answer my question either.

I have the subject system in my car. US Spec IS350 RWD F-Sport. The manual says the on/off switch is to the left of the steering wheel on the lower part of the dash. I have no such switch in that location.... Where is PCS on/off switch.

my ES300h was hit on the front bumper while parked in a parking lot. It's now been at the dealer for 6 weeks trying to find the cause of the "brake" light coming on with three quick beeps for NO apparent reason. This has been happening since the collision, and with each trip to the dealer they think they have it fixed..... I can't find a common denominator for what causes the light to come on, and cannot replicate it.

Twice now I've been driving and there was a few second lull where pressing the gas did nothing. The first time I was passing a car on the right, and the other I was pulling out between two cars to make a left on a busy road. Is there some kind of collision detection system that's causing the loss of acceleration? It's odd that the 2 times it happened I was so close to other vehicles. It's concerning since I needed to pull out quickly the second time and I was stuck for a few seconds without acceleration.

So I've been driving my tiggy with the rusted brakes from when I left it for a few months during this past winter season outdoors. I had VW check on it and they said that the only way to fix the problem is to replace the brakes (rotors and pads, I assume) for over $1k. Is there really no way to maybe scrape/sand the rusts out? Right now, when I step on the brakes, I have the pulsating feel and the car shakes when coming from a high speed. At first I thought it would go away after driving it a bit and stepping on the brakes since I did just that last year when I left it for a month during the winter season as well. If the only way is to have the brakes replaced, then I guess I have to shell out the money.

2002 Camry LE 4cyl. automatic. I bought this car with 7500 miles on it in 2010. It had been involved in a low speed parking lot collision and apparently the left front corner and front took the hit. It'd been repaired and looked like new when I bought it. It still had the factory tires on it, but they were 8 years old, so I put a set of new Kumho Solus' on it. This was a friend's mothers car, so I know the history of it.
The left front suspension has always felt odd to me. Nothing serious, but just "off." When backing up and turning it has a sort of wobbly feel on that corner at times. I've been assured by several mechanics that they can find no problems. It feels to me like maybe sometimes the strut piston sticks on that corner. Don't know if that ever happens or not, but that's the best description I can come up with!
It has always vibrated from 45 on up. It's not a hard shudder, but just a constant vibration at highway speed that you can feel in your feet and the steering wheel. I've had it balanced and re-balanced to no avail. Sometimes it gets a little better, sometimes worse, but it's never gone away. Recently it seems to be getting worse.
I put it up on jackstands and accelerated to 60, and it vibrates like the wheels are out of balance. Yesterday I replaced the Kumhos (they had bad road noise anyway) with Michelins. The Michelins cured the road noise problems and have a much better overall feel, but I've still got the balance problem.
Just put it up on jackstands again and spun it up, and I still have the same vibration!
What to look for? The car has just now turned over 35k miles. I'm wondering if the CV joint on that left side was damaged and is causing the vibration. I've got new wheels as well instead of the factory steel rims. Also, with the car up on stands, the wheels spin true. No bent hub, etc.

I have had an issue with a clunk in the rear end. Passenger side. It was only happening when I would hit a bump. Over the last couple days it has started getting worse. At about 40 mph and above the clunking will increase and can be fairly rapid. Also have a slight vibration at that speed. Do not feel it in the steering wheel.
I think I have narrowed it down to the rear knuckle? bushing. While holding onto the bushing I rocked the top of the tire in and out to produce the clunk. I could feel it in that spot. I had ordered a set of bushings, months ago, which claimed to be a direct replacement.
Tonight I decided to try and swap them out. Should be easy. Nope. The old bushing will not come out. I have some pictures. Maybe I need to call my mechanic in the morning? My diagnosis might be wrong anyway?

My 2006 Gx470 Sport (KDSS), with 82k miles, has a clunk/loose suspension feeling when going over potholes. It doesn't happen when going over speed bumps or anything other then a pothole.
I have experienced at each corner of the suspension, so it isn't just one corner that is bad. So if for example I drive over a pothole on the driver side, I feel the clunk on the driver front wheel as it goes into the pothole, and then again as the rear driver tire goes into the pothole. The same thing happens if I drove over a pothole on the passenger side as well.
Since it happens at all 4 corners, I am wondering if it may be something wrong with the Xreas Suspension, or KDSS.
Also, this is the first vehicle I have driven with KDSS, so maybe this is a normal feeling of that system. Everything else with the suspension feels normal.

My 2005 GX (108k miles) seems to be in great shape. When i replaced the front CV boots i looked carefully at all suspension components and i did not see anything damaged, loose or suspicious.
However, when the truck is SLOWLY moving (entering into my driveway or getting out of parking spot), and when i turn the steering wheel ALL THE WAY to the right, i hear and almost feel a single semi-loud clunk from under the car. I am 99% sure it is related to the steering movement. When the car drives straight or when i am making smaller turns on the street, there is no clunk, noise or vibration at all. I haven't noticed it during U-turns yet, but maybe i haven't paid enough attention. Something must be loose or worn out. The clunk is very obvious when it happens.
Where this could be coming from? Any well known weak components in the front suspension setup that may need attention at 108k miles? I am thinking about tie rod ends or sway bar links but i am not sure if a bad tie rod / link would produce such "clunk" when turning all the way.

I have a new-to-me 2007 GX470 with 150k miles. Clunk sound doesn't always happen and is not that bad. It usually happens when I stop quickly, not on a gradual stop. 150k service was done 2k miles ago, so it might have been greased.
Will this cause any issues with the vehicle if drive shaft is not replaced? Is it just annoying? Is there any chance that Lexus will fix on a vehicle with 150k miles?

My 2007 GX470 is making a clunk/thud noise when braking (more often when braking hard or on a downhill slope) and then again when I let off the brakes and start to accelerate. It is significant enough that I can feel the car jerk some when it happens, almost as if someone has tapped the back with their car. What it could be?

Common issues that arise with GX470. From what I know I will list the first 2 that I know of:
1) Clunk sound from driveshaft
2) dashboard cracking

Why are My Tires Wearing Unevenly?

I have had my 2007 GX for 5 months now. I have discovered the "clunk" issue and had the dealership replace the driveshaft. I want to start a new thread because I have a different clunk. The new driveshaft has fixed my clunk issue at a stop but I have one more. While driving in the city or leaving the highway on the exit ramp (transmission is in overdrive) and I press the accelerator I get a clunk.
This only happens when the transmission is shifting out of overdrive. I can repeat this clunk while driving around 30-40 mph. I will coast a bit then accelerate enough that it wants to shift out of overdrive and then "clunk". It sounds loud but not much of a jerk. I have 85K on it and did not perform any fluid changes in the drive train yet. Transmission is sealed so not sure if it is worth changing or just leave it and drive nice so it don't clunk.

I have a clunking sound coming from the back end. It is most noticeable at lower speeds going over bumps. I can also make the clunk happen by grabbing the top of the right rear tire and rocking it. I can feel something moving while I am doing this, but I can't pinpoint it. The bushings seem to be in good condition. The left rear wheel bearing was replaced recently. I also have an intermittent brake pulsation which feels like a warped rotor. I don't think it is actually the rotor, because it doesn't happen every time I apply the brakes. I believe that these two things are related. Is it possible for the rear struts to cause these issues?

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?
