Lexus SC430 :: Loud Buzzer Noise Behind Dash On Startup
Sep 16, 2013
Have had SC430 for over 10 years, 94000 miles. Have loud buzzer sound behind dash on startup or when key is turned to on position. The sound last 10-20 seconds and goes off. I have turned the AC off and tried different modes, no change. Everything seems to be working fine with the AC. Could this be a servo motor, the noise is not coming from the engine compartment. Any thoughts on problem and how to fix it. It makes this sound on every startup.

Irritating lifter noise that is pretty loud when I cold start there engine in the morning. Have had the roadster for about 6 months and it has 122,000 miles.
I did not use the car for 2 months while I was away.

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 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.

Occasionally, when I start my 07 I hear a loud zip noise that seems to be coming from the front of the car somewhere. I know it's kinda tough to pinpoint. Something running against the teeth of plastic gears comes to mind.
I should also mention that it happens immediately after the engine has started, about the same time the self leveling headlights start to move.

So I don't know if its the starter or the intake manifold that is making that loud noise it sounds like i have a big supercharger on it or something every time i rev the motor u can hear it spool like a turbo...

Got an '02 here. This noise started to appear recently. When I turn the key to put electricity on (without starting the car), I hear this electric motor-like sound, similar to power window sound, coming thru the dash area, and it can also be heard outside the car coming from somewhere in or near the engine compartment or in front of the dash/windshield area. Could this be one of the servo that operates the AC vents? or its something else?

I just got it and the gauge is showing a little hot. I took it in they found nothing. The fans runs almost all of the time. It even started running when I was sitting in my driveway with it in park (it was about 55 degrees outside at the time). I also hear some grumbling noise in the dash on the drivers side. It sounds like something is trying to work (the radio is off and it still makes this sound).

I have 2010 GS350 and after starting the car several times yesterday there was a very loud clicking noise coming from the dash near the glovebox.

My dash lights are very dim during daylight and marginally bright at night. This is for a 2002 Lexus SC430.

It just happened yesterday on the freeway, as I hit a small bump. Need to mention this stretch of freeway has those extremely annoying ridges that make everything rattle inside the car, besides the deafening tire howling. But after they're gone, all used to be well. Yesterday, after said bump, this very loud noise behind the center air vents started all of a sudden. It increased with speed.
Sounded like a motor turning. Thought it was the NAV motor (which I never use), but opened it and closed it, and it functioned well. Tried the motor for the stereo cover, and also worked fine. When the motors were operating the sound persisted. The noise disappeared below 50 mph. And not even in broken pavement was present. After speeding above 50 again, now in smooth pavement, it was back. I guess it's there to stay... until 'killed'.
I HATE dealers going on a fishing expedition in my cars, so prefer to know what the heck is causing it, and preferably do it myself (don't trust the only dealer in town). I'll try to tackle it myself, but no way I can live with that noise, so a trip to the dealer seems almost certain, as I don't have a service manual yet to get behind the dash.

We have a 2004 and 2007 SC.
I notice that the dash lights on the 04 are dim compared to the 07 even though the dash control switch is turned all the way up. Is this the nature of the car or is there a setting that can be adjusted through the computer?

I just got home from a 650 mile trip and I have pinpointed something I have been hearing for a while but couldn't figure it out. It's a very very faint rattle (something like the sound a hard drive makes) and it seemed to be coming from behind the dash. I experimented a little today and this is what I noticed.
It is actually coming from somewhere around the gas pedal and it only does it when you are neither accelerating or decelerating. In other words, when the engine is at equilibrium if that makes any sense. It's a tiny sound and I should just turn the radio on and forget it, but it's just one of those little things that bugs ya.

One of my exhaust manifolds has been really loud for over a year now, just at startup. Sound becomes more quiet as the engine heats up.
No lights on dash, but I do have emissions here so I'd like to get it fixed early 2016.
Curious what the shop charges for this install. Or if it's worth it to do both at once.

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.

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.

Just picked up a pretty nice 2002 sc430 today. On the drive home I realized all the dash backLights are not lighting up. However the The radio and climate control unit do have a dim backlight working but is stuck at one level of illumination.
Like most cars the all dash lights should be very bright during the day and when you turn on the headlights they should all Dim down. ..... Not on this SC.
Makes no difference what position the headlight switch is in....Nothing changes or lights up
and
The little Dimmer does nothing either when turned all the way one way or the other.
Fuses? I am not sure what to try.

The last couple of days when I started the car it didn't turn over immediately as it normally does. Now when I turn the key the dash symbols all come on; radio, lights, etc work fine. I hear a strange close sound like lite weight metal fluttering which continues as long as the key is turned to start. But nothing beyond that.

So I've recently noticed a small "bubble" forming on the passenger side of my dash above the glove box. What this can be from or what could have caused it. I'm hoping that it doesn't have anything to do the with the airbag recall.

I just installed a new set of OEM LED taillights on my 02' sc430 bought the kit etc but I cannot get the dash rear taillight sensor to turn off. I called the local lexus dealer thinking they might have to reset it and spoke to the lead mechanic and he said i would need to rewire the lights.

I replaced my brake pads and rotors and now the driver's side brake has a loud pitched squeal. It doesn't squeal all the time and if I let up on the brakes and apply them it goes away.
I think maybe one piston is hung up.
How do you free up a stuck piston in the caliper piston?
Or could there be another reason for the squeal.
I installed Callahan slotted rotors and ceramic pads on all 4-wheels.
