Engine Noises Your Hyundai Shouldn’t Be Making

1. A hissing noise could indicate a coolant leak.

Your engine coolant helps maintain the engine temperature safely and saves the engine from overheating. If you pop the hood and hear a hissing noise, it could signal that your car is leaking coolant. A coolant leak contributes to low levels of coolant, which can cause your engine to overheat and, thus, put a damper on your car’s performance. When you put coolant into your vehicle, use the recommended type for your Hyundai model.

2. A squealing noise when starting your car

This engine noise could mean the serpentine belt needs replacement. The serpentine belt in your Hyundai connects the engine to the various pulleys that operate accessories like the alternator, power steering, and air conditioning compressor. Any damage to this belt will cause it to squeal and cause erratic accessory operation. A trusted Hyundai dealership in Breinigsville, PA, can help you resolve the issue.

3. A clicking noise when turning

Every time you take a turn, you should hear a faint clicking noise. This is due to the CV joints on either side of your car’s axle shafts. The clicking noise is nothing to worry about and is quite normal. However, if the noise is loud and accompanied by a grinding sound, it could indicate a problem with the CV joint, and you should have it checked out by your Hyundai service professional.

4. A grinding noise when braking 

Your brakes are not meant to last a lifetime. Sometimes we tend to forget this, but they are made up of several parts that can wear out over time. If you hear a grinding engine noise when you brake, it could indicate that your brake pads are getting worn down and need replacement. If you ignore this, the metal backing of the places can start to grind against the rotors, causing even more damage.

5. A rattling noise

A loose exhaust pipe or heat shield is often the cause of such car noise. To break it down, your car’s exhaust system comprises a series of metal pipes connecting the engine to the muffler and tailpipe. The heat shield is a metal sheet that covers the exhaust system to protect it from the intense heat generated by the engine. Over time, these parts can loosen and rattle around, causing that distinct engine noise.

6. A thumping noise from the engine

When your engine misfires, it can cause a thumping noise. This car noise is often caused by a spark plug that has gone bad or oil accumulated on the spark plug. Such issues with the engine should be fixed as soon as possible as they can cause long-term damage.

7. A knocking noise

To distinguish a knocking noise, pay attention to a certain rapping or banging sound that increases with the car’s speed. If the knocking noise happens when the vehicle is idling, it’s likely due to an issue with the engine.

Low oil levels often contribute to engine knocking, so keep an eye on your car’s oil levels and get it changed regularly.

However, if the noise occurs when accelerating, it might be due to a problem with the piston or connecting rod.

8. A humming noise

Your engine starts to hum when it’s having trouble functioning properly. The bearings that help the crankshaft rotate start to wear down, which makes a humming noise. Loving your car means learning to love and care for your engine.

A minor problem with the bearings and this humming engine noise can point to some significant issues you cannot detect now. Act smartly, and don’t wait for this humming to worsen.

9. A ticking noise

Your engine valves do more than one job. They open and close the passageways that allow air and fuel into the combustion chamber. When they do their job, they make a ticking noise. If that ticking noise becomes more pronounced, it could indicate that your engine valves need adjustment or replacement.

In other words, ticking engine noise is a sign that your valves aren’t either closing or opening properly. What happens when you don’t resolve the engine valve issue? Well, be prepared for more severe engine damage and repair bills.
