Lexus SC430 :: Sound Like Marble Rolling Through The Roof Or Dash Of Car
Nov 7, 2012
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've noticed an annoyance with my car lately. I've noticed when I turn either right or left upon starting my car, that i hear a small sound, as if a marble is rolling along the inner windshield but it never runs the entire length of the car to the other side. I have noticed when I make a right turn, it occurs on the right corner of the windshield. When I make a left turn it occurs on the left corner of the windshield. Never runs all the way across the windshield like something is actually rolling along the windshield edge or behind the dash.

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?

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...

I have recently started to hear (at frequent intervals) a loud buzzing sound that can best be described as a phone vibrating/buzzing while its on a table. The sound happens every few minutes and is pretty annoying. It seems to be coming from around the navigation area or glove compartment - i cant pinpoint it. I turned off the radio and AC and the sound is still present. My Navigation Wood cover has been STUCK for a few months (doesn't come out and shut nor tilt) but not sure if that is the cause here. What can be causing this sound?

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?

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.

When I push open for the convertible, nothing. No light no warning nothing.

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).

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!

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?

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 know VW's are quirky. When I shut the engine off, around 5 seconds later there comes a funny marble dropping sound from the engine compartment. It sounds as if you were to drop a marble on a table and let it bounce a couple times. I can't figure out what it is.

2010 Prius with 100,020 miles on it. Car has had regular oil changes on schedule with M1 0W-20.
Noticed engine rattling/marble sound at low RPM under load a few weeks ago. This is not just when the engine is cold or on startup. Sometimes when hot. It's also not all the time. It's felt/heard over on the pax side. Just wondering where to go (dash/engine mount?). I did download the TSB for rattling but the local dealer has never heard of it even when they asked their tech (?!? How is that possible?). It's a good dealer so that surprises me.
What to look at? No codes so far.

I just had my front passenger window replaced due to an attempted break in, and I noticed now that my window sounds very harsh rolling up and down versus my other three windows. The window goes up and down at the same speed as the other windows that wasn't touched, but now its just not as quiet as the others; which to me now is more of an annoying sound.

This just started out of nowhere ... I took a sharp turn and all of a sudden, it sounded like a marble running from the left to the right of the dashboard. Took a turn in the other direction, and the "marble" rolled from right to left.
It is definitely not something that fell into the dashboard, so I feel it must be a component that came loose under the dash. But is there really a "channel" that runs across the length of the dash? Is there a way to access the innards without having to remove the whole dash assembly?

i keep hearing a noise under the dash by the radio. it is almost a gurgling noise if that makes sense. i don't know if it is the cd player doing something, or something else.
