Why Is Your Car Making A Whistling Noise?

Whistling Noise When Accelerating

If your car is whistling when you put your foot down, it could be due to a couple of things. Check the weatherstripping on your vehicle to ensure it’s all intact. This is the soft seal that runs around the edges of your windows. If it’s worn out or damaged, there might be gaps allowing tiny amounts of air through. As you pick up speed, the air will be pushed through with more force, causing a whistling sound.

Alternatively, it could be a leaky vacuum. Any wear and tear to the hose could result in the air that is supposed to travel to the engine escaping. Just like with the weatherstripping problem, the fast you go, the louder this whistle will sound. You’ll also notice that the efficiency of your car will take a hit if the vacuum is damaged, so it’s best to identify this problem as soon as possible and get it fixed.

Whistling Sound From Car Wheel

A whistling noise that seems to originate from one of the vehicle’s wheels could be caused by a number of things. The most common issue lies with the wheel bearings, with a worn or damaged wheel bearing preventing the wheel from rotating smoothly. This should be fixed urgently as if it was to completely fail during a drive, it could have a fatal impact.

Your brakes could also be at fault, particularly if you’ve had work done to them recently. If that’s the case, it might be worth heading back to the garage that completed the work so they can check that everything was put back together properly. It’s unlikely that your brakes will be damaged or in a dangerous condition, but it’s still worth getting it looked into as soon as you can.

Whistling Noise From Car Air Vent

First things first, it’s important to establish the true cause of the whistling noise. It could be down to a blockage in the vent, most likely some kind of debris from the road. As a matter of fact, it could be something as rudimentary as a leaf that’s been sucked inside. If this is the case, the solution is simply to get inside and clear this obstruction.

It may also be caused by a broken seal (which seems to be a running theme when it comes to whistling noises) that will need to be fixed. Take a look under the bonnet at the pipework attached to your vents and see if there is any noticeable damage. If you’re able to locate a hole or other damage, then you can use thick, waterproof tape to cover this air escape. In the long run though, you’ll be better off getting this component replaced by a professional.

Whistling Sound When Car Is Idling

Ultimately, this one most likely boils down to the same kind of issues that we’ve already covered regarding other areas of the vehicle. In fact, a whistling sound when the car is turned on by not moving could once again be down to a broken vacuum seal.

If that’s not the problem, check the car’s water pump to ensure it’s all in one piece and undamaged. If it has seen better days, it’s a good idea to replace it before the problem grows.
