Two fixes: When raising the roof, stop it halfway. It reveals a round rubber bump stop that sits against the rear parcel shelf. The bumpstop can be adjusted by rotating it. If you raise the bump stop, it sits harder against the parcel shelf and reduces movement, thereby reducing noises. Also, lubricate all roof and boot (trunk) rubbers with glycerine (glycerol).

There is a creaking or groaning from the driver's side front when turning left at very low speed, like in a parking lot. When parked, turning the steering wheel in place intermittently causes the same thing but only when the wheel is turning to the left. No noise when coming back to center or going to the right.
Noise is definitely not a clunk or pop or squeal. No difference in handling at normal driving speeds.
Jacked up front driver's side tire and tried push/pull at 3, 6, 9, and 12 o'clock positions. Nothing strange, even with enough force to be concerned with jack support only. Pulled the tire and checked out tie rod end and tie rod. Pushing and pulling saw no movement. Grabbed swaybar link and push/pull, all solid. No leaks or worn boots on any of them. Checked PS fluid--fine.
Should I suspect lower control arm ball joint? Is noise consistent? Maybe it needs grease? Unfortunately, car is far from home, so the biggest question is whether it is safe to drive hundreds of miles before sorting it out.
Recently bought a CPO 2010 RX350 with 57k miles on it at a dealer on 8/30/14. Its developed quite a bit of interior rattles and creaks from what sounds like the structure over bumps and roads that aren't smooth. Plus the sunroof has a high frequency rattle. None of these were present during the test drive.
View 9 RepliesMy 2008 rear suspension creaks and squeaks and groans when I move my horse trailer. Truck has 32k miles, has done since purchase last year, squirted wd 40 and that works. At ford place now, they say it is because I added the ride rite air bags. Told them it made same sound before I installed. What to tell them (tech service bulletins ?) or give up and keep spraying and looking for dry joint?
View 1 RepliesJust bought a '02 Sc430. The navigation screen pops up but is unresponsive to touch input. I tried to search for a thread with this issue but couldn't find one.
View 2 RepliesI've went onto TIS and received some info in regards to the electrical components of 2002 sc430.
Fuse 19 on Passenger Box: Interior light, personal lights, vanity lights, foot lights, ignition switch light, trunk light, antenna, garage door opener system audio system.
Each time I install a new fuse, it immediately pops. Wondering how to diagnose root cause. Often it seems that wires ran through door grommet can become exposed....I have done no modifications to the vehicle. Not sure if there is a particular area I should start looking for exposed wires, I have a feeling it is going to be a long process with my skill level to find the short.
I am a new owner of the 2007 SC430. I wonder how reliable is the roof folding in the SC? I heard that many SC having a either mechanical or problems or electrical problem after a while? Is that true?
View 14 RepliesMy roof will not open. When I press the button, it only opens the rear trunk and could hear the roof motor unlocking functioning, but will not open. It only opens about a couple to few inches and stops. It seems tho it's going to open, but gets stuck.

View 14 RepliesSqueaks, rattles and anything else that makes noise (other than the stereo and especially my wife) You can imagine my total horror when I went around a corner and I heard what sounded like a marble rolling through the roof or dash of the car. I've been able to replicate it a few times but I have to be cornering pretty hard to get it to do it. I have had 1/2 of the top apart.....3/4 of the dash apart, under the hood, in the glovebox and console as well as underneath the frame and I cannot for the life of me find the source of the noise.
View 4 RepliesSo i haven't used my top for awhile because it's been really hot in texas. I tried it for the first time today and I can't even get the open close switch to blink red? I did a ecu reset by unplugging the battery for 30 minutes nothing. I check the fuses in the trunk and they were all good. I did install the VIas awhile back but I don't think it could be the temp control? I'm assuming if it wasn't plugged in all the way the AC and other functions would not work.
View 14 RepliesIn an earlier thread, I talked about my roof stalling at the end of an opening or a closing operation. I just returned from a 260 mile round trip to the Lexus dealer to address this problem and get some other maintenance done..
To recap the problem, the roof appears to complete the opening or closing operation but won't finish it by turning off the red light on the switch. The switch then won't respond to either open or close. The roof stalls. It does this about 1 in every 10 or 12 open/close cycles.
Of course, if you drive the car with the red light still lit, you're treated to a chime when you go over about 5 MPH. Also, your trunk is locked.
I repeatedly re-try the switch of course, but without success. I eventually restart the car. Either the switch recovers or restarting does the trick, because so far I've been able to get the switch to work again. I would assume the stall will eventually stop being intermittent.
So, I talked with the Lexus service tech and he said he is very familiar with the SC roof. After hearing the symptoms, he quickly diagnosed a failing proximity switch. He was confident they could diagnose the problem.
So, I was due for the timing belt replacement and decided I'd have Lexus address both issues.
As I suspected, they need to catch the roof stalling to diagnose it. And guess what: They could not get the roof to stall. When the tech called to say my car was ready, I was disappointed my roof could not be fixed. The tech really did not know much about the proximity switches, like how many are in the roof. When I asked, he said replacing them all would be expensive and they did not believe one switch could be identified as the culprit from the description of symptoms.
So, here I am back 130 miles from the dealer with a tricky roof. I am thinking I will find out whether any local mechanic (Toyota or an independent) can find and fix the bad switch when it does fail.
Fortunately for the rest of you, the tech says this is not a common problem. I am aware of the manual operations to raise the roof, but really hope I don't have to go there!
I just got a beautiful red '06 with only 19k miles. It's my second SC, and I can't believe how much I missed it after a four year break.
However, there's already trouble. The roof only opens intermittently. When it works, it's all good, no vibrations, nothing off track, smooth operation all the way open and close.
When it doesn't work, the red light on the open/close button will NOT light up. Nothing happens at all. I will come back to the car a few hours (or minutes) later, and it works fine. The problem never occurs for closing, only opening. Also, several times now I have closed my roof, and then immediately tried to open it again, but no deal. Those symptoms make me think it's not the ECU, but one of the sensors.
BTW, there is no Luxlink installed yet. I have yet to find one that includes the double-click option
Having a problem when going over speed bump or drain at the end of your driveway?My roof makes a popping noise?
View 6 RepliesI have this strange creaking almost a sharp cracking noise coming from the rear part of the roof near my head when I go over some bumps. I have tried all the usual methods; lubricating roof rubbers, adjusting bump stop under package shelf; adjusting roof height using the grub screw adjustment; nothing seems to work. It almost sounds as if the noise is coming from some of the hard plastic roof trim but I can't seem to pinpoint it despite using foam padding, silicone spray etc..

View 20 RepliesI have 2002 sc430 that i purchase new. I now have a rattle from roof on driver side back behind my head above the little window....
View 10 RepliesSo I finally decided to look into all the little creaks and rattles that the R makes while going over bumps in the road.
-Wrapped the latches of the rear seats in electrical tape, and put adhesive velcro (soft side) on the back of the seats where it meets plastic.
-Took apart the center console and put adhesive felt around the areas where plastic makes contact with other plastic
-Put adhesive felt inside the aluminum trim & Monsoon radio to stop shaking
So all those little fixes eliminated most of the rattling sounds in the car. All that I need to look into are the driver and passenger doors to secure whatever is rattling/shaking inside those panels. Something to do this coming week. I normally would leave these noises alone, but damn they drive me crazy like it's a form of Chinese water torture. I hope to have no more rattles in the following week.
The closest thread I found was this [URL] ..... The straight rod that goes into the windshield from the roof, on the passenger side, does look a bit worn. should i tape it up? I started having this problem recently. Never heard this noise the past.
My sc430 is giving a loud pop right over passenger's side from roof, whenever my car goes over a bump or rough road. I think it's where the front hardtop latches are. Only on the driver's side. It's a loud pop sound.
Does this have something to do with the latch, or latch motors, that closes the power roof ? Would it work if I tighten the retractable top by turning the rubber button in the center back of the car, the one that exposes during roof operation as outlined by other posters here?
Looks like my struts and springs are getting old that they're making squeaky noises over the bumps. Had a shop checked to make sure and they suggested replacing them. I've been wanting to do air ride but not a lot of good shops in town have done that before. So far by searching, most complete kits run around $4k or so without installation. Is that about right? How complicate is it to do the installation?
My second option was to purchase coilovers and put them in myself. Cheap and easy. But again, there are 4-5 brands out there? Megan, D2, BC, K-Sport, etc? I want it mildly lowered and not too bouncy. What spring rates should I get?
So, we've had our first "big" storm of the year. I say that with quotes because it was only an inch or two and some pretty serious ice.
I got the SC430 out of the driveway with a little bit of effort, but had a heck of a time trying to get it back up the driveway. It was getting stuck on the slightest bumps. As you can probably imagine, Michigan gets feet of snow, not just inches. I'm afraid if it gets stuck this easily, I won't be able to keep driving it this winter.
I'm going to try putting some sand bags in the trunk as it is my main car. But if that doesn't work, I am going to have to put her away for the winter and start driving my crappy 6-cyl 2.7L Hyundai for the winter (front wheel drive).
