Same clunk when stopping or after at a complete stop, letting my foot off the brake.
14000 miles...a clunk is heard and slightly felt when coming to a stop or upon accelerating from a stop. This occurs under normal driving, no hard braking or fast starts.
I have complained to Lexus each time I take my vehicle in for service and they have replaced drive shaft and arms and it still happens. They just continue to note it on my service receipt but nothing is being done about it. I am starting to keep a log with dates because this is not normal. I have never ever had this happen with another vehicle and this is the most expensive vehicle I ever purchased. I have never been so disappointed and do not think I will buy another Lexus.

We recently purchased a 2008 Lexus GX 470. We did our research and it was rated at the bet SUV in it's class. It should be for the amount of money they demand. We took a test drive and everything was as advertised. We bought the vehicle and within 30 miles or purchase, it started to make a clunking sound every time we stopped at a red light or stop sign. I don't believe it has anything to do with the brakes as we've read elsewhere, because we have them engaged at each stop. It sounds more like the AWD system or something related to it, is engaging and disengaging. Not sure, but it is very annoying. We are going back to the dealer today to attempt to get it repaired or LEAVE it there for good.

At a complete stop for a minute and feels like I just got hit from behind. I'm being told I need an "updated drive shaft" about $800 bucks. Based on what I'm reading, I could be in for a lot more money. I asked if "updated" meant recall and I was told no. Will find out tomorrow if resolved.

It is a thunk in the rear right when getting to a stop or right when releasing the brake to start again. The dealers said this is common in Toyota and Lexus vehicles due to the way the brakes adjust forward or backward when coming to a stop in forward or in reverse. When driving, I am told, the position of the brake pads is vertical, and they rotate forward when coming to a forward stop. The clunk is when they return to their normal vertical position. I had a 2005 GX470 and never hear this (sold at 120,000 miles). I bought the 2007 second hand. The prior owner had replaced the pads without going the additional $99 to refinish the rotors. I had the rotors refinished, and that eliminated high-speed brake shimmy, but did not solve the clunk. I suspect the former owner had the pads replaced at a brake store using after market parts that might not have the proper springing for the rotation of the brakes as described above.

Has a clunk when ever you release the brake after a complete stop.also has a bang feeling that happens when idleing in park.its as if someone banged the car from behind.

Will feel the thump even after having been stopped for a full minute at a red light....

Problem just diagnosed have not fixed it yet.
My car "clunks" and feels like I have been rear ended, when almost stopped or starting off, just after letting off the brake. This is one of many problems on this $53,000.00 car. I have 105,000 miles on it and it needs about $4500 worth of simple maintenance to be driven comfortably and safely. I have 2 older chevy's I drive both with over 200,000 miles each and no issues at all. I think Lexus should have recalled the suspension problems with this vehicle and should not ask owners to pay the $2000.00 cost at the 105,000 mile service! What a piece of crap!

It started at 40K and it got worst over time. I am told it is the rear bushings and to just ignore it. Don't like to drive a clunky car. Any chance we could make enough noise to Toyota to recall these vehicles ?
Clunk sometimes when starting off and sometimes after being at a full stop. You can feel the entire truck move. Just bought the truck from local Lexus dealer and I am taking it in for repairs.

Occssional clunk at stop. Feels like someone taps my bumper. Never corrected.
2007 Lexus GX470 45,000 mi,
I had noticed that the vehicle juddered ahead when resuming travel, having stopped for stop sign, or stoplight. When asked, the previous owner told me that Lexus said it was normal. Reading a few websites, it seems to be a design problem, and I would have thought that Lexus would have made it right. I have tried all combinations of soft vs. sporty suspension, and high versus low, versus medium suspension setting, and have also reset the rear brake adjustment of hand brake. All these guesses to no avail. It's still not fixed.

Clunk When stopped or stopping. Sometimes when slowing down and then speeding back up. I'm not if it's coming from the back of the vehicle though. I can't pinpoint exactly where it's coming from.
2004 Lexus GX470 60,000 mi,
My Lexus has done this clunking thing from the time I purchased the vehicle used in 2010. I thought it had something to do with the transmission until I read all of these reviews! I tried to fix the problem by having the transmission flushed. I have been very disappointed and frustrated with this problem! Wow, I'm disappointed in Lexus!!! This should have been a recall!
