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.
My car - a 2007 4 cylinder Hyundai Sonata - is making loud screeching sound more than occasionally but not all the time at high rates of speed (70 - 75 mph) and ESPECIALLY when I am exiting the highway to go to the train station and I turn to the left on the exit ramp. Never the right - only the left, and it stops immediately when I touch the brakes.
About 6 weeks ago, I had 4 new tires put on, and thought maybe they were not installed properly. I saw a mechanic today who put it up on the lift and said everything looks in good order and he could not find anything wrong with the driver's side front wheel, which is where it sounds like the noise is coming from. Of course, when we drove around in it, there was no noise. In fact, after I dropped him off and went to the train station it DID make the noise, so I turned around, picked him up and drove back exactly the same way - no noise.
It is a very, very loud uninterrupted screeching sound.
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.
My wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?
On occasion, I have had rattle noise coming from above the radio and behind the nav screen.

I have a 2007 LS I purchased a few months ago. Wind noise from windows is very loud. I applied the jmcraney fix this week - did it exactly as the directions say. Made no difference in wind noise - still get a bunch of wind noise through the windows. My LS has 70k miles so it is out of warranty.
View 14 RepliesI recently purchased a beautiful 07 LS460 with 24K miles about 3 weeks ago.
About 2 weeks ago, I noticed a loud clicking / hammer noise from the dashboard lasting about 15- 20 seconds and after reviewing numerous threads here, I realized it could be my blender door / damper due to the infamous cabin air filter change. .
It must be noted that the Dealer did not change the cabin air filter and when I looked inside my glove box, I could easily open / close the blender door using the recirc ac button. Additionally, my cooling and fan is working fine as well, so I am not too sure that this is a blender door issue.
My question is that the noise continues to happen for about 20 seconds when the car is started and shut off. Since my blender door / damper opens and closes smoothly, is the servo motor going bad or servo sub assembly?
If it is my servo motor, could it be possible that it was damaged when the cabin filter was replaced? With the car only bearing 24K miles, I cant believe my servo motor has already gone bad!
I picked up a 09 ls460 swb a few months back and am slowly turning it into my daily.
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.
The sound system in my 2008 LS 460 suddenly stopped and a loud thumping noise comes up in all speakers even if the radio is turned off. There is no music at all only that loud noise. Bluetooth does not work as well as command voice and the GPS guiding system. I had to remove the fuse to stop the thumping sound. To answer my telephone I must pull on the side of the road and turn off the motor. Car dealership said that it is the first time they see that. The car is scheduled to be looked at in a couple of days.

View 1 RepliesLoud engine grinding noise accelerating from stop when you first start the car? It is right after cold start, lasts 10-15 seconds until I get to 30-40mph. Engine sounds normal otherwise.

I've isolated this rattle down to the cam phaser( CVVT) in the right cylinder head. It rattles bad for 2-3 secs on cold start or after it sits for 3 hours.
I've put in 5w20 synthetic oil and synthetic Lucas additive and it cleared up the noise for short interval start ups.
I changed the cam phaser in the right head with a used one ( 40k ) but it didn't make a difference. I should change out the attaching cam as well.
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.
When the car is in a situation where there is a twisting force, such as entering an inclined driveway from an angle, a loud POP is sometimes heard from the rear of the car. The intensity of the POP varies dependent on speed and angle of incline, higher speed/greater incline/decline produce a louder POP.

I have a 2002 Prius that is running fine except for a loud noise when I started it up---like the one the exha fan in my bathroom makes, but the car runs well and there are no lights or any other indicator that anything is wrong. I am taking it to a local mechanic today, since I don't trust my local dealer. My car has about 95, 000 miles on it.
View 7 RepliesWhen I start my car I hear this very loud noise. I think it is coming from the exhaust but not sure. This only happens when the car is cold(not weather) and after a few minutes the noise is gone. I have aftermarket lowering springs on the car, do you think that caused the problem?(I'm thinking no)...
View 4 RepliesHere is the noise that I am getting... Ignore the ticks and such, I'm talking about the LOUD whining noise at startup, and continuing at idle(although somewhat quieter)

Some information : 2006 Camry 2.4L.
I have removed the belt to verify that the noise is not from any belt-driven components. Using an Engine Ear, it gets louder towards the exhaust manifold, but apart from starting to tear things down.
