right after i turn on the engine and start the car moving in reverse or drive, the car make a slight (or sometimes loud) clunking noise that seems to be coming from either the brakes or the transmission. i cant tell because its subtle sometimes and frickin loud other times.
anyone else have this problem ? it seems to occur only within the first 5 minutes that i start the car.
Sounds like you are talking about the brakes. If so, it is normal, Lexus uses a floating caliper desing. When you first depress the brakes, they make that noise.
All my lexus' have done it.
hmm.. tested it out today.. im not even stepping on the brakes when this occurs. upon closer inspection it seems as if the car whirrs, sounds a lot like clunking though. this happend after i got the car moving in drive (about 4 seconds after it started moving forward)
I've had my used 2002 IS300 sportcross for about a month and have been concerned because I hear that eaxct thing. Usually after the car has been sitting for awhile. When I back out of my driveway in the morning for work I put the car in drive, go a couple of feet and "clunck". It's a hard sound to discribe. ZY
When I park on a steap hill or driveway and put on the parking break, I feel the car roll back about 1-2 cm and it makes a creek noise sometimes. I'm thinking its the breaks, but I just got the car in Feb'04. Is this just the type of breaks?
I try to pull the parking break harder but doesnt seem to help as much.
Hi, I have purchase my used 02 IS for about 4 months now. I have exactly the same problem. I didn't occur to me that this noise would be a cause of concern when I bought it becase I was so excited about the car. Anyway I have taken my car to the dealership for this problem. After 3 hrs of waiting the service dept rep brushed it off as a brake problem. I wasn't satisfied so I checked with the sales rep who sold me the car and he was kind enough to test it out with me. He too reconized that this is abnormal and he had consulted their so call "master technician". Their conclusion was that it was the electrical system of the car calibrating, and that there is nothing that they can do about it. Again that left me unsatisfied but I had to leave due to all the time already wasted. Sorry for the rant but has anyone been able to find out further what the cause of this problem and the remedy may be? Thanks in advance to helping out.
my 02 is having the same prob. i took it to the dealer, after 1 day they said it was normal, abs system clunk when u initiate the system. and there is nothing they could do to fix it.
My '03 has been doing this since I remember...in the morning, backing up, and turning...clunkclunk!! I maybe get one more clunk on my first turn (depending on how fast I am trying to get to work)
i always thought it was the u joint and it was not a big deal. like it's not used to going in the reverse direction so much so when you do back up, it just gives that noise. hard to explain, but i never worried about it
OMG.. I thought I was the only having that problem. I have the same problem. I just recently bought an '02 IS300 at the dealership. Whenever I back out of my driveway I hear a clunck sound as well. Thats the first thine I noticed. I know I have a 30 day grace period with the dealership. So, I'l bring it up and I'll come back and let you know wat they said. Takecare guys.

Its completely normal. As said, the design of the brakes encorporates "floating rotors" which make that noise (they're a much better design). Not a worry there's NO fix.
Fyi, (not a brake related noise) these cars have a pretty loud transmission(when shifting). Of course mine is a 5sp maybe its different for an auto. If that is any help
Oh Right! Thx for the Info. I was getting scared there for a bit.. I was like "Man.. just bought the car and I am already having a problem" ... lol.. Butcha man.. All the worries are done now ^^ ..
Im fairly new, but i have a 2005 is300, and my car was doing the same thing. i took it to the dealer about a month ago, and they said it was a problem with my steering wheel, they replaced my signal switch. However when doing so, they messed up and put one without a fog light, and the car was still making the same clicking, ticking noise. i returned my car to the dealer and havent heard from them in about three weeks now!

Did you bother to read anything? We have listed the cause of the click about 10-15 times throughout this thread. THERE IS NO PROBLEM The noise is part of having floating rotors. Floating rotors dissipate heat faster, and are much, much better for performance cars. Most performance high end vehicles have floating rotors and guess what, they make this noise!
I got the car when it was a year old. I thought the front sway bar needed lubed, but that didn't fix the noise. Then I discovered the bracket bolts were loose where it mounts to the frame/body.
I checked up and it appears that both floating rotors and floating calipers are used on high performance brakes. So, I guess either is correct. The reason is to isolate the brakes from the suspension.
i took my car in way before i read these threads, but it seems as though thats not the only problem, or else my car would have been returned back to me weeks ago, im going on the 4th week now!
I hate to bring back a dead thread...but this one should be stickied. I swear this clunking noise had me worried when I first got my car. I thought...such a nice car and now I have to fix something already. It wasn't until my brother drove my car and told me "hey, the IS has that brake/rotor system that clicks when you first drive it". That made me feel so much better knowing it was normal.
To the other guy who's had his car with Lexus for 4 weeks...that's BS man. Lexus should know of this noise by now and just be more forward explaining it.
