Car Noises That Need Immediate Attention. If your car is making any strange noises, it’s important to get it checked out as soon as possible. This is especially true for the following five noises: hissing, popping, grinding, squealing, and knocking/pinging. Here’s what kind of problem each noise could be indicating:
Hissing:
A hissing noise from your car could indicate a coolant leak. If you notice this noise, be sure to check your engine coolant level and look for any leaks. Other causes include an overheated engine or vacuum leak.
Popping:
A popping noise from your car’s exhaust system could indicate that the catalytic converter is damaged. This is a serious problem that should be fixed immediately. Popping noises can also be caused by leaks in the fuel injector.
Grinding:
A grinding noise from your car’s brakes could mean that the brake pads are worn out and need to be replaced. If you hear this noise, be sure to get your brakes checked as soon as possible. Grinding noises can also be caused by your transmission. Listen for grinding noises when your car shifts gears or when you are using the clutch to determine if it might be the transmission.
Squealing:
A squealing noise from your car’s engine could mean that the serpentine belt is loose or damaged. This is a relatively easy fix, but it’s important to get it done before the problem gets worse. Squealing noises that happen when you are applying the brakes could indicate dirt buildup on the brake pads, shoes, rotors or drums.
Knocking/Pinging:
A knocking or pinging noise from your car’s engine could mean that the engine is low on oil. This is a serious problem that should be fixed immediately. Check your oil level and add more oil if necessary. Knocking noises can also indicate significant wear and tear on your engine parts that could lead to a major breakdown.
These car noises are serious issues that require immediate attention. Many of these noises can have multiple causes. Having your car checked out right away can help you know what kind of problem you’re facing and how much it will cost to repair.
