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 RepliesToday I tried opening my roof... The trunk lid opened but the top didn't fold.. I closed it... After restarting my car I realized the front switch for the top doesn't even light anymore...
I unplugged the battery... replugged.. the switch opened the trunk lid again but top didn't move and switch was a solid red light... once I pressed closed, trunk lid closed and switch stopped lighting after (not responsive). What it could be?
My 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 RepliesTwo 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).
View 12 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 3 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 RepliesThe 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?
I have had this slight rattle sound in roof driver side rear which comes randomly if road is bad or bumpy.. It doesnt bother me but would be nice if it wasnt there. I don't know what it is but seems like some wire or something inside in corner which shakes...
View 14 RepliesMy self-closing door feature on my driver door has stopped working recently. The other three doors self-closing door feature works flawlessly.
Is there an easy solution, such as a fuse? Or, does something else, more extensive, need to be done, i.e., should I seek out a professional mechanic?
As an aside, around the same time (if not the same time), my folding side mirror for my driver door stopped working. Any possibility they are related?
I have a 2012 LS 460. When the moonroof is closed the aft section is not flush with the roof. It's about 1/4 inch low. I don't think this is normal.

How to drop the roof panel on a 2007 ultra - luxury....have an annoying "cracking soon" at the top front area of the sunroof. It does not appear to be the sunroof as I still get the sound when the roof is open and I'm going over an uneven area...say driveway onto the road. I would like to have a look but don't want to damage the air curtain bags.

at an angle causes a loud popping noise from my roof. I checked the headliner to see if anything was loose but came up with nothing. This occasionally happens on sharp turns on uneven ground.
I recently lowered my car so now this is happening way too often.
My 2007 ES UL has started to peel at the edge of the glass of the rear roof panel. It was originally just at the rear corner and I assumed it must have been scratched and the due to dryness started to peel. Then I noticed it at the other rear corner. I asked them to look at it at the dealer and the service advisor told me it was from the UV rays which dried it out, and not to worry about it. I bought and applied einszett gummi pflege stift to those corners and all seemed well.
Now that it got colder here in NY the corners again began to pop up but today I see it's started to pop out very much in the middle of the panel which seemed fine before!! The SA had told me that this (gasket, molding) comes attached to the roof and to fix it I'd have to replace the panel! I'm scared my UL is sick of the panoramic roof just for show and wants to be able to open.
