Intermittent whistling sound coming from front of car

I've noticed an intermittent whistling or squealing noise coming from the front of my car. It's not apparent when I first start the car and is most noticeable when I'm in gear but stopped, like at a red light. (Although this could just be that I'm not moving and thus it's more apparent to me) it's also not a constant noise and there's no discernible pattern. The overall performance of the vehicle has not been affected – when I start it, accelerate, brake etc.- there's no difference that I've felt. Everything else functions just fine and none of my alarm l

Hi there:

The sound you’re describing is very similar to a serpentine or drive belt that is beginning to show signs of being loose or damaged. As the belt progressively gets looser, this noise will become more noticeable until it’s constant. The best thing you can do is have a professional mechanic complete a car is making a noise inspection to be sure that the belt is the source or have them replace the belt that’s causing the noise.

A high-pitched, shrill whistle can really get annoying, especially if it occurs frequently while you drive. There are generally two possible explanations for the whistle. The first is that your vehicle is running low on transmission fluid. The second is that your car`s fuel injectors have gotten too dirty.
Constant circulation of air and cooling fluid through your car`s engine can cause small cracks in hoses, breaking their vacuum seal. The whistling sound you are hearing could be air escaping through these holes.
The sound you are hearing is air leaking across a damaged gasket or a warped sealing surface. With the throttle closed, or in deceleration mode, the manifold pressure is very low and if there is a leak anywhere in the induction system that should normally be sealed, you will hear the (very common) whistle.
Air flowing against and around the vehicle can be deflected by components protruding from the vehicle. Misaligned body panels or door gaps, mirrors, sunroofs, windshield wipers, racks, loose pieces of molding, or protruding edges can create body turbulance or whistling wind noises.
Adding a Door Sweep or a Door Seal can help greatly in reducing outside noise, airflow, and noise caused by the airflow. A Door Sweep is designed to create a tight fit around any door and also canceling out any airflow that may be flowing through the underside of it. This will reduce the noise flowing under the door.
Strange Noises

If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.

Have you noticed the whistling noise when you accelerate? This happens when there is a potential leak in the vacuum system of your car, although it is a very common issue, it does mean that your car is not operating at full efficiency and if it`s left untreated, it can result in a costly repair bill.
Friction in the hinge can be caused by a build-up of dirt or dust, or a lack of lubrication between the metal surfaces of hinge and hinge pin. It is this friction and rubbing of metal on metal which causes the squeaking sound.
Bad Pulley Bearings

Over time, the bearings that facilitate smooth spinning of the pulleys can wear out. If the pulley on your alternator or other accessory isn`t spinning freely, it can cause a squeaking noise as you drive along.

The most common reason as to why your suspension is squeaking is due to a lack of lubrication. Your suspension is made up of two metal and one rubber pieces, so without proper lubrication you won`t have a quiet ride.
Transmission fluid ensures that the gears shift smoothly, but there will be a clunking sound in manual transmissions and whining sounds from automatic ones if it is low.
Over time, and alternator can wear down. If it`s the bearings in the alternator that have worn out, it may make a high-pitched squealing noise. This means that it`s time to have the alternator replaced.
Usually this type of noise in an indication of a exhaust leak or a vacuum leak due to a broken or disconnected vacuum line. If you also notice that your car is slow to accelerate or is running rough, then it is likely that one of these items is the root cause.
There are three explanations for a car that makes a whining sound, including transmission problems, power steering issues, and engine problems.

Car sounds like golf cart when revving and braking; also leaking fluid; sound fades as car warms up
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

A large clunking noise is coming from the front left of my car anytime I start my car, and anytime I go over a pothole/speedbump
ANSWER : Hi, thanks for writing in. If simply starting your car causes a clunk, then you may have another damaged motor or transmission mount (there are 4 total). You should replace all 4 mounts. When one mount fails, it allows excess motion of the engine/transmission, damaging the other mounts as well. It is false economy, generally speaking, with the age and mileage of your Honda, to do them one at a time. If you would like help with these replacements, consider having an expert automotive technician from YourMechanic come to your home or office to perform the engine mount replacements for you.

Every time i let go of the gas there is a squeaky sound coming from the front of the car like where the two front tires are?
ANSWER : When throttle is applied, power is transferred to the front wheels and the resulting torque adds pressure to the suspension system. The squeak can be coming from a suspension component at the front of the vehicle or the pedal itself. Hire an experienced technician, like one from YourMechanic, to diagnose the noise firsthand and see if a part need to be replaced or just needs a little extra lubrication.

When I turn on my AC the radiator fans do not turn on. The fans do come on when the car warms up so I know they are working and the fuses are good. The AC compressor does come on and the air blows ice cold when the car is moving. Car is a 2006 Chrysler Sebring Sedan 2.7l v6.
ANSWER : The control circuit for the fans needs to be checked. For example, there is usually a condenser fan relay in the A/C electrical controls. There could be a fault with that relay and/or wiring problems, perhaps even just a loose connection, blown or loose fuse, and so forth. To resolve something like this, the recommended service is an electrical component diagnostic. If you request that diagnostic service, the responding certified mechanic will get the problem pinpointed and resolved.

Charging warning light comes on when i turn the key and try to start the car and the car want start but when someone tried to give
ANSWER : Hi there:

If you recently replaced your battery, the issue may be caused by a malfunctioning alternator or other electrical component that comprises the charging system on your Nissan Sentra. The best way to find out which item specifically is faulty, is to have a professional mobile mechanic complete a car is hard to start inspection. This will allow the mechanic to determine the precise source of what’s going on with your Sentra and recommend or complete the right repairs.

Hearing a knocking/popping sound somewhere in the front of the car when driving.
ANSWER : There could be multiple issues causing the mystery sound you’re hearing on your 2005 Mazda. My first inclination would be to check the steering stabilizer bar bushings, but if those were replaced, it could be an issue with your wheel bearings. In many cases, when wheel bearings are starting to wear out, they will cause a clunking or grinding sound to occur when you turn the wheel all the way to one side or the other. If you need further help with this, I recommend having a qualified professional from YourMechanic diagnose the noise and assist with repair.

My car makes a loud humming like whoop sound when I accelerate past 50 MPH and gets louder the faster I coming from front end.
ANSWER : If the noise suddenly appears at 50 mph, then check the brake system as there could be an issue with the brake pads rubbing the rotors. If the noise starts off quiet and gets louder with speed, then check the wheel bearings as they are out of grease and the bearings are rubbing metal to metal. If you need further assistance with a humming noise at 50 mph, then seek out a professional, such as one from Your Mechanic, to help you.
