Lexus ES 2007-12 :: Rattling / Growling Noise When Car Is Running With AC On

I've recently experienced a rattling(vibration)/growling noise around the engine when the car is running with the AC on. The sound gets louder when I put the car in drive and it goes away when I turn the AC off. The sound seems to be coming from underneath or next to the engine(right of engine when sitting in the car/left of engine when standing over the hood facing the engine)

I took it to Lexus and they told me its likely the water pump. The car drives great and I'm not noticing any leaks(water or otherwise) underneath the car. I had to park the car for 6 weeks while on a military exercise, and don't recall hearing the noise before going away. could 6 weeks of inactivity on the engine have anything to do with this?

Lexus LS 2007+ :: Light Rattling Noise From Suspension

Not sure if this is normal with the air suspension but over poor city roads at low speed, there is a light rattling noise from the suspension. I think it is the front. Sounds like worn bushings but the car has only done 30,000 miles.

If this is the sort of early symptoms that would be expected with wear in the control arms?

Lexus LS 2007+ :: Grinding Noise When Braking While Cold

I just had new pads(ceramics, not sure of the brand) all around and new front rotors installed from a local shop that I trust. When braking while cold, there is a grinding sound and feel, I took the car back to the shop, they've acknowledged the issue, double checked their work, and are willing to replace the pads if it continues, which it has. Is there a break in period for ceramics, should I specify a different type of pad.

Lexus LS 2007+ :: Ticking / Rattling Noise Coming From Underneath The Car

Experienced a noise that is evident when the side window is down which seems to coming from underneath the car. It is difficult to describe but it is a ticking / light metallic sound. Possibly coming from the exhaust system area. It is particularly annoying at a drive through window where the sound reflects off the building.

Lexus RX 2004-09 :: 2007 - Faint Rattling Noise While Driving

Our 07 RX350 has 47,000 miles and I just starting to hear (I think from the front) a faint rattling noise while driving. It's hard to describe but it sort of sounds like what you might expect if an empty plastic bottle was slowly bumping around in a plastic box. It is not a metal on metal type of noise. The shocks/struts appears to pass the old bounce test and the car does not seem to display any of the handling issues you get when you have worn shocks/struts.

I also checked the upper engine compartment to see if any plastic shrouds or covers were loose - they weren't.

Lexus RX 2004-09 :: 2007 - Rattling / Grinding Noise While Accelerating From Stand Still?

I have a 2007 RX350 with about 243,000kms on it. I recently purchased this car and everything is great on it except one thing. As of late, I've begun to take notice that when I accelerate from a stand still (for example after stopping at a light/stop sign), a loud rattling/grinding starts and then as I pick up speed and change gears, it fades away. The sound is more rattling than grinding. As if there is a metal bowl with some smalls stones in it and someone is just shaking that. There is also another sub issue that I'm having. There seems to be a clicking noise every time I apply the brakes or even accelerate. The same clicking noise reoccurs every time I put the gear into drive from neutral. However, when I do that, there is only click as opposed to braking/accelerating, where there are many. I'm hoping this is all part of the same issue and not isolated issues.

Lexus LS 2007+ :: Actuator Noise / Pump Pulse Sound During Braking

My 2007 LS 460 makes a noise like a pump pulse sound during braking. When I step on the brake before coming to a stop there is no noise but once the car is 20 feet before coming to a complete stop at times you feel and here a pulse or pump or vale sound in the front engine area. Sometimes as I increase pressure on the break pedal a little harder you can feel and here a single pule and at times 3 or 4 valve or break pump sound. What might be going here? I am certain the sound is not coming from the wheel area. It is definitely under the hood. Could it be a faulty load sensing proportioning valve or booster?

GTI 337/20th Anniversary :: Weird Rattling Noise When Engine Braking

I recently installed my 3" GHL exhaust along with my stage 1 BFI dogbone and I recently noticed a very faint rattle when I am engine braking. I can only hear it when there's no cars around or when its quite. but i cant figure it out. (I still have the stock exhaust heat shield in from the cat back so I am not ruling that out as a possibility).

Lexus LS 2007+ :: Popping When Turning And Braking

I currently have a 07 LS460. I've been rather happy with my car, until now. Over the last month I've developed a popping noise when turning left and braking. I took the car to my local import specialist, there it was determined that my lower ball joints were going bad. After a few day of looking and calling around...I can't find them! Lexus says I have to replace both steering knuckles because the ball joints are pressed in! I refuse to believe this! Is there anywhere I can just buy the lower ball joints without the knuckle?

Lexus LS 2007+ :: Clunk When Braking In The Rain

This problem is recent and only happens when it rains. When braking to a stop, I get a thunk or two. I only having hearing in one ear, so where the sound might be coming from. I ruled out loose things knocking around. The last time I was driving in the ran, I got the thunking only the first one or two times I braked, and then nothing. Other times I have gotten it repeatedly in a single drive. I have never gotten it while braking except when coming to a stop. I don't get it when merely slowing down in traffic or the freeway. I back into my driveway and I am wondering if braking in reverse has any bearing on this problem.

I searched here and on the internet. The problem exists out there as I have described it, but no posts that I can find have identified the problem. The truck has disc fronts and drum rears. I took the front tire off on the drivers side when I re-seated the front wheel bearings. I was going to repack them, but didn't feel like pulling the caliper, so I just re-seated them. I repacked them not that long ago and didn't feel it was worth the trouble at the time. I didn't bother to pull the tire on the passengers side. While I was at it, I greased all the ball joints.

I can't recall exactly when I first started hearing the clunking, if it was before or after the whole U-joint/carrier bearing campaign, but I became acutely aware of it afterwards, perhaps because that's when we got a lot of rain. There is absolutely no driveability issues at all, just the clunk when braking to a stop in the rain.

Lexus LS 2007+ :: Rattling Sound At Low Speeds While Driving

I started hearing a small rattling sound coming at low speeds while driving. It's a tic tic rattle which almost sounds like a cat, but it only does it while driving and not all the times. I had a smiling noise once on one of my cars and it was a torque converter. It's not the brakes, as applying brakes doesn't work. Also the whole front end is brand new. It motor related. Can a heat shield for a cat come loose?

I'm also dealing with a wind noise coming from a driver side window. My car has the updated thicker windows. The noise goes away if I lower the driver side window just a fraction. So having it closed all the way creates more noise. Other than that wind noise is at a minimum.

Lexus LS 2007+ :: Sloshing Sound On Moderate Braking

Both my wife and I noticed that whenever we brake moderately to hard, we can hear water sloshing around. The sound is coming from the driver side underneath, like maybe from the gas tank? Is this normal? We just purchased this car last month (2007 LS 460L) and love it! This is our third LS (Ls 400, 430 and now 460). What's going on?

Lexus LS 2007+ :: How To Access Rear Subwoofer - Blown / Rattling

I'm trying to access my rear subwoofer in my 07 LS 460 with Mark Levinson. It seems to be blown or ripped somewhere as it makes a loud noise when it hits. Will the top grill just pop off? Or do I gotta do a full removal? If so, how do I get to it.

Lexus LS 2007+ :: Suspension Rattling Clunking Sound On LS460

Why my suspension is so loud and clunky are doing a swaybar link and upper control arm replacement? I did remove the air suspension unit in order to access and remove the bolts that hold the upper control arm bracket mount onto the frame.

I did not think that would do any harm. Now my suspension is way louder than it ever was to begin with.. I just did a visual inspection and saw that my original parts were cracked and worn in the bushings and links. So I did a swap.

Camry :: 2007 LE - Rattling And On / Off Hissing Noise

I recently obtained a used '07 Camry LE (2.4L with 120k miles) and thought to clean the throttle body when I changed the spark plugs. After putting the intake compartment and connecting everything back together (I'm assuming correctly), the air filter box along with the hoses seem to rattle a bit more. Today, I popped the hood after a short drive and discovered a on/off hissing sound -- it's possibly this sound started the day I worked on my car.

Thought I would post a video clip : [URL] ....
