What to Do About Mysterious Car Sounds
Noticing a strange sound for the first time can be distressing. But try to take note of the type of sound and how you were driving.
One-off sounds likely won’t be a problem, but you should have it checked by a mechanic if it happens repeatedly. Trying to describe an abstract symptom can be difficult. Luckily, you can collect a few bits of information to make the repair process go smoother.
1. Record the Sound
A lot of sounds are just too difficult or abstract to correctly describe or imitate. Is there a difference between a thwap and thud or screech and squeal? Luckily we don’t have to always rely on awkward mimicking while at the mechanic.
If you can ready a smartphone, or have a passenger do so, and make a recording of the noise you are hearing. Or, if you have a dashcam that does audio recording, make a note of the time to review that later. It can also be helpful to dictate the questions in the section below onto the recording.
Take your recording to the mechanic for them to review. Having it recorded can give them a better idea of your troubles without them having to try and replicate it themselves.
2. Note Down Driving Conditions
While getting a recording can be incredibly useful to help convey the type of sound, perhaps even more important for the mechanic to accurately diagnose the cause is what the driving conditions were when it occurred. When you hear a sound take a mental note of as many of the following as you can and write it down for your mechanic.
- Is your car moving when it happens, or is it at startup or idle?
- Does the noise occur at a certain speed, on acceleration, or deceleration?
- Is the noise occurring when you turn?
- Is it accompanied by any physical shaking or other tactile feedback?
- Does it get worse under certain weather conditions like extreme cold, heat, or moisture?
3. Common Strange Car Sounds You Might Hear
You’ve got your recording and notes in hand, but you can’t get to the mechanic for a few more days, or maybe even a week, and you may be asking whether it is safe for you or the vehicle to keep driving. Some mechanical problems won’t cause significant damage within that time frame, but others might put you or other drivers at risk.
So let’s go over some of the common strange sounds you might hear and their potential level of concern.
- Humming on Acceleration: A low-pitched hum that increases as you accelerate and then levels off at speed (your RPM drops but hum stays) indicates an issue with your wheel bearing. Bad wheel bearings can be dangerous as they lower responsiveness and, if ignored, can cause your wheel to come free.
- High Pitched Squeal on Start: If you start your car (or air-conditioning) and hear a loud squeal, you have a belt that is worn or needs to be re-tensioned. For short trips and cooler weather, as long as the car starts driving with a bad belt isn’t necessarily a safety hazard. But it should be addressed quickly, before it causes a more significant problem.
- Squealing While Turning: A high-pitched squeal while turning may indicate low power steering fluid or a problem with the pump. Both are big issues that can make driving dangerous and difficult.
- Hissing while Driving: A hissing sound is indicative that a hose is not attached correctly. If it happens to be the radiator, driving any further can cause significant damage to your engine in a very short amount of time, so pull over and get your car checked promptly.
- Grinding when Braking: If you notice a grinding or scraping while braking, you might have an issue with your brakes. A noise the first time you brake when driving, especially after rain, can be expected, but if it happens every time you need to stop, get to the mechanic. Your brake pads, fluid, or shoes are at fault and put you at risk of not being able to stop.
There are too many potential mysterious noises to go over here. No matter if you have been driving normally for years without issue. If you notice something out of the ordinary, it is always best to at least call a mechanic and get their opinion.
