I have a 2005 SC430. When I start it up it makes a squealing noise, and the more I accelerate, the more it squeals. I read through this entire thread: [URL] ....
I did as PearlPower suggested and sprayed it with some WD-40 (the top center pulley area) and the noise stopped, but not for very long. Think I need a new belt.
I have a 04 BMW Z4, and noticed a squealing noise when I accelerate slowly.
View 3 RepliesWhen my heat or air conditioner is running it makes noises (loud squeaks and squeals). The only way for it to stop is if I run the heat/ air conditioner at the lowest setting. Right now its cold but if I don't run it at the lowest setting, the sound is loud and really annoying... I thought it was maybe a loose cabin filter but I checked that and its fine. Where is it coming from?
Driving a 2006 Lexus GS 300 AWD,
when i initially purchased "used " my 08 gs350 i had a problem with brake squeal. I kept taking it in to the dealer until they ended up changing front rotors , all 4 pads , and new shims .
Took my car into my usual mechanic to get an oil change. I knew i needed brake pads and he changed all four pads out for $350 .I am having a terrible time with brake squeal now. the mechanic is telling me that i have warped rotors and need to replace all four. He is telling me that he wont charge me labor, but the parts will cost $400.00 I goggled the cost of the parts and he isnt far off on the price . My concern is that his fix isnt the correct fix. Front what i can tell its the front rotors making all the racket.
What should i do ??I dont know if they re-installed the shims and have no idea what kind of pads were used . Thinking about taking it to the dealership and being done with it .
The water pump was the culprit for the noise. So my 2013 gs350 with just over 40k miles started making a clicking and squealing noise during start up and while driving. I took a video of the noise when started cold without the a/c on.
I've already taken it in to the dealer for service but out of curiously, what the problem may be? I'll provide an update after the the dealer completes service.

(2008 ES 350) I hear this squealing noise under the hood, I had the AC compressor rebuilt because I was told that was the cause, low and behold it's not, I only hear the noise when the car is in gear, but I don't hear it when in park or when I drive, but it's loud in drive and reverse. The water pump has been replaced too. Where is this coming from?
View 2 RepliesMy father-in-law's 2001 Lexus RX300 makes squealing/whistling sound when engine is cold. Multiple serpentine belts replacements and adjustments made no difference. One mechanic said it's the bearing inside the alternator, but I find it difficult to believe. Why would bearing sound go away when it heats up? Besides, having issues with bearings inside things like alternators and such.
View 1 RepliesI have a 2008 GX and when the car is in drive and being stopped/held in place with the brakes, it makes a squealing noise, sounds like a loose belt but I don't think it is as it is coming from the transmission area, BEHIND the engine.
View 3 Repliesi 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.
View 2 RepliesOver the past year I have been hearing a noise coming from the rear of the car. It seems to happen when the car is running and almost sounds like the fuel pump priming itself, but it happens when the car is running. So I don't think it would be that.
It doesn't happen all the time, it might but I miss it due to the loud levels I tend to listen to the stereo at.
My other thought is that it might be from the one of the top motors to raise and lower the roof.
When I start my 2003 SC430 I hear this screeching noise. It sounds like it is coming out of the dash but it may be under the hood because my neighbor heard it outside the car.
View 9 RepliesThere's been a recent annoyance that's appeared in my '03 SC 430 with 32K miles. I've noticed over the last 3 months that whenever I have the A/C turned on, after a few minutes, a soft chirping sound appears. It sounds very much like a cricket chirp to be exact, kind of high pitched, but continuous. It's even loud enough to hear over my music.
I realized that it came from the A/C because it was gone whenever I turned the A/C off. I initially thought it might be from the belts for the A/C compressor, but I couldn't hear anything from the under the hood with the A/C turned on. I'm thinking it might be something to do with how the coolant flows in the lines, but can't be sure.
I'll probably have it looked at during my next oil change.
The SC I recently bought is quite quiet except for a helicopter noise at speed.
This noise becomes obvious at around 70 kph (40 mph) but can be noticed at lower speed (volume much lower). I don't think turning the wheels or braking makes a difference.
Since it's speed-sensitive and there's no noise when the car isn't moving, I guess it's related to the wheels. I've just replaced the rear tyres last weeks; nothing changed. I've checked the tyre pressure today; may have got a little improvement (not sure) but the noise is still there.
Is this the wheel bearing noise? Or is this tyre noise? Could the differential make this kind of noise (the only other thing I can think of that's speed-correlated)?
Also, as an aside I pulled the fuse on the te/ti steering the other day because I'm too lazy to use techstream. I swear there's a noticeable improvement in the steering accuracy and feel. Really don't know why.
Grinding noise (light) in the steering column on turning the ignition key on, after few hours of parking in hot sun only, the movement of steering column is to the set memory, after that no noise, cold start in the morning is always noiseless, feels like it needs lubrication?
View 7 RepliesThere is a noticeable amount of wind noise on the driver's side (obviously with the top and all windows up). Haven't ridden in the passenger seat so not sure if it's there too.
The top closes perfectly, so I'm assuming it's the driver's side mirror.
I have an 07 sc 430. It has a wind noise on drivers side. It seems to be at the top of the window where the top fits into the header bar.

2010 SC 430 Matador Red 30,000 miles.
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.
View 4 RepliesIrritating 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.
So, I have Stoptech rotors and brakes, and it squeals when (a) it's warm after a few minutes of driving and (2) only when I initiate braking softly to slow down, but disappears after braking firmly to stop. Brake pads have about 80% left on them.
View 4 RepliesI have a 2005 sc430 and the starter went out so i changed it but after i had change it its making a loud noise. 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...
