Lexus SC430 :: Roof Stalling At The End Of Opening Or A Closing Operation
In 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!
Lexus SC430 :: Trunk Not Opening With Remote Or Dash Button
Other than checking the fuse and the valet switch, anything else to look for when the trunk will not open via the key or the dash switch? The car does make the beep when the key remote is pressed, but no open. Also, the top works fine. Gas door works fine. Manual release of trunk also works.

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
Golf V R32 :: Hatch Not Opening When Press Unlock Button Several Times On Remote
I've been having an issue with my hatch not opening the first several times I press the unlock button on the remote. For reference it's the car door unlock button I'm pressing, not the hatch one as that one has never done anything when I've pressed it.
I thought it was due to the faulty rear view camera I had installed (the emblem pops out) but I just got a new one installed 2 days ago and it's doing the same thing. It's gotten so bad I've had to go open the drivers door and press unlock from inside there to get it open.
I'm wondering if there is a problem with the latch getting stuck or something. I've never had it not close all the way or anything like that which I hear is more common than the issue I'm having. I will take a pic of the pin in the trunk that I'm talking about.
Lexus SC430 :: Roof Folding In 2007?
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?

Today 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?

Squeaks, 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.

So 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.

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).

I have a 2002 SC430 And its the second one I've owned. And for the life of me. I can't remember if the side windows lowered a little when you open the doors. The past five or so cars I've owned did. But this one doesn't.
To clarify. The windows (Both driver and passenger) Would drop about 1/8" when you open the doors and raise up once the doors are close. is it normal that the Sc doesn't do this?

View 6 RepliesLexus SC430 :: Creaking / Cracking Noise From Rear Part Of Roof
I 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..

I woke up to a surprise this morning , the car earlier had this kinda issue where i would press the start button and it would not start and only make "Click" sound .. and after few attempts it would usually start and then this issue went away for few months for unknown reasons
Today it returned back i didn't move the car for 2 days over the weekend down here. I tried to start the car all it would do is Click sound but this time a very faint sound not like earlier where it was much louder .
I am assuming its the starter ? Where is it located ? What i read online and see could be just a bad starter selonoid .

View 10 RepliesLexus GX 2004-09 :: Have To Press And Hold Button To Open Or Close Moonroof
Recently, I have had a problem with my moon-roof, this is the second time this has happened. Normally when you press the open button, the roof slides all the way open, slides all the way closed and sealed when you close it. It also opens when you remotely open all the windows. OK, for some reason it stopped doing that! You have to press and hold the open-button to open or close it, and when you close it, it won't seal right unless you tap the button just right as it closes. When you open all the windows remotely, the moonroof remains closed.
The first time it started doing this, I took it to my friend's independent Lexus service center (now defunct) and Lee did something with the button to reprogram it and the moonroof worked as before. Recently it stopped working again. I don't know if I pressed something I shouldn't have or what! I assume that there is a way to reset/reprogram the moon-roof, just like there is a way to set the doors to lock - unlock when you shift the car into drive or park? What can I do to save an expensive Lexus dealer reset? My car is 2004, Levi/navi and loaded.
Lexus SC430 :: Front Roof Popping Sound Over Passenger Side On Rough Road
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?
