Lexus IS 2014+ :: Rattle / High Pitch Noise When Engine Running In 3500 - 4500 RPM Range

I've noticed a noise coming from my car (2014 IS350 RWD) that sounds like a light, irregular rattle, when the engine is running in the 3500 - 4500 RPM range. I don't hear it necessarily under load, but if I am in manual mode in a lower gear, and let off the throttle, I can hear it.

The best way I can describe the noise is like a bowl of rice crispies (rapid and random), only slightly louder. You have to listen for it, the road/traffic should be quiet, and if you get back on the gas, the intake noise that's plumbed into the cabin pretty much covers it up. I can also hear it in Park or Neutral.... I've wondered if it's a loose heat shield, or an exhaust issue, but I can't hear it standing next to the car or with my head under the hood. I only hear it from the cabin. The rhythm of the noise is irregular.

I don't think it's ping/detonation, since that usually shows up under load, is much louder and has a decidedly metallic sound to it compared to what I'm hearing.

Santa Fe (CM - 2007-12) :: High Pitch Noise On Audio System

I purchased a new 2011/2012 Santa Fe (R2.2 VGTi Auto 7 Seater GLS AWD) recently and noticed a high pitch noise on the audio system. This high frequency disturbance is audible with the engine off (eliminating the alternator as being the source). This is also present with the volume set to a minimum.

Prius (2004-09) :: 2005 - High Pitch Noise That Won't Stop And Locks Up?

I tried to start my 2005 Prius this morning and a high pitched noise started (the same noise that happens when you hit the power button without having your foot on the brake). The emergency light was locked on as well as a message on the display screen about setting the emergency brake. This has happened one other time an after about two minutes the noise stopped, and I was able to start the car. This time the noise and lock remained for about 20 minutes until we disconnected the battery in the back. We re-attached the battery after we removed the ignition key and after a few moments all the power seemed to be gone. The fob doesn't work at all and the electronic lights and dash flickered and faded out. Our gut instinct is that the battery needs to be replaced. Was it the 12V battery?

Lexus - Es300 :: Low Pitch Growling In Reverse / High Pitch Screech When Apply Brakes

I have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.

My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.

Lexus GX 2004-09 :: RPMs Started Surging While Idle And High Pitch Humming Noise When Accelerating

My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.

Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.

What could be the problem? Could it just be the battery?

Saturn - Sl - Wheels - Transmissions :: Low Pitch Squeaky Type Noise When Turn While Driving / Parking

So I heard some low-pitch but still the squeaky-type noise under the wheel when I turn it while driving/parking. In addition, once in a while, while driving the car, it will automatically honk on the street. I sense the car may need some check-up for its electric system. But what shall I do at this moment?

I have a 2003 Toyota Prius, that you have to push sooo hard to make it stop, the ABS and brake light are on and there is some aweful chime that is solid and doesn't go away (very high pitch), I just got the car, and got it like this. I think its signs of a BRAKE BOOSTER, but I have been unable to loacted that, I found the Master Cylinder, but looks like you have to remove the Hybrid engine to do... Is there a procedure for this...

Dodge - Grandcaravan :: 2014 - High Pitch Whining Under 2000 RPMs?

I just drove away in a new 2014 Dodge Grand Caravan - had 106 miles when I took title at the dealership - and immediately noticed the most annoying high pitched whine or whistle. It seems to occur under 2000 RPMs and starts around 25mph. It continues until about 45 mps and then either becomes less audible behind the engine noise or stops - hard to tell. When the car slows down, it comes back -- most of the time. It changes in pitch as the car goes faster and as it slows down.

It has been so loud at times that I think it's a police or ambulance siren and I have gotten ready to pull over. It does not happen in neutral when I rev the engine - the car has to be moving. Turning the wheels doesn't seem to make a difference. I am going to take it in to the dealer but I suspect they will just laugh and say that's how the car sounds. I've never had a car that had such an annoying soundtrack - and I've rented about 5 of these minivans over the past 3 years and never experienced this, either.

Elantra MD (2010-15) :: Click Noise When Apply Brake To Stop From Either A Very Low Or High Speed

I think something is wrong with my brake. I only have less than 3k miles on my 2012 Elantra GLS. But now, when I apply brake to stop from either a very low speed or high speed, I always hear a clear click (only one) sound which probably comes from under the car or brake pad (front driver's side). It sounds like metals collision. When idling, applying brake does not make any sound.

Elantra GD (2013+) :: Spoiler High Stop Brake Light Has Heavy Condensation

Noticed water droplets or heavy condensation in their high stop brake light (2015 model)?

I've noticed a small crack. The crack seems internal and not completely through so I don't think that is the reason. There also seems to be a vent around the water washer nozzle which should allow the light to dry out. It just seems to be taking days! Do that gap around the washer nozzle is intact a vent or are theses lights sealed. My one is the LED version.

Lexus GS 2013+ :: Squeaky Brakes When Come To A Slow Stop

When I come to a slow stop my brakes squeak. I took the car to the dealer and had to prove to them that the brakes actually squeak. I drove around and pulled back to the service area and keep driving and stopping and the brakes squeaked every time. They supposedly replaced the brake pads, however, the brakes still squeak.

Ford F-150 (2009-2014) :: 2013 XLT - Brake Grinding Noise Before Stop

I have a 2013 XLT Scab that has been in twice now for a low speed to stop brake rubbing or grinding noise. The first visit they turned the front rotors and scuffed the pads, which seemed t fix the problem for about a month. The second visit they repeated the same process on the rear and the problem was good for about two months. Today while driving I noticed the noise, probably worse than I have ever heard. It seems like after about 20 stops the noise gets quieter. I am taking it back for the third time and I am hoping they will fix the problem for real this time. I am tired of burning my gas to get to the dealer and then having to ask my salesman for a loaner car. Other than this issue I love the truck.

Ford F-150 (2009-2014) :: Warning Light Came On Along With A Message To Check Brake System

I have a 2011 F-150 Supercab 4x4 and the brake warning system is starting to drive me nuts. A couple of months ago the warning light came on along with a message to check brake system. I didn't find anything wrong, even flushed the hydraulic system. all seemed OK. Now the warning came back on, the message center will reset and the warning light will reset after shutting off the truck.

I can drive in city/town and the warning does not come on. But if I drive open road for about 30 miles with out using the brakes I get the warning again. I'll reset the message center and it'll clear, then about every 10 miles it chimes and shows to check brake system. It is strange that that I can drive hundred of miles in town using the brakes and not warning but get on the open road and not using the brakes I get the warning after 30 miles.

Toyota - Corolla :: 2002 - Engine Noise On Acceleration - A/C High Pitch Noise

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.

Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?

Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?
