This can be caused by a number of factors, which of course you need to know. The sound of a car engine hums, of course, can interfere with comfort when driving.

1. Troubled Power Steering Pump, Making Car Engine Buzzing Sound
The first cause of the hum of the car engine can be caused by the power steering component starting to experience problems. Usually this happens to cars that still use hydraulic power steering. If your car already uses EPS, aka electronic power steering, you don’t need to worry. Because obstacles like this will not happen to your vehicle. Cars that still use hydraulic power steering, usually have components that are sticky to the car’s engine whose purpose is to supply energy and ease the steering load. These components have bearings.
As the bearings start to wear out, a buzzing sound will be heard frequently. Especially when the steering wheel turns, this sound will be heard more clearly. For those of you who have a car with hydraulic power steering, you should regularly check the condition of the vehicle’s power steering. Especially when the hum began to sound.
2. Bump or Wavy Tire
Another factor that can cause the car engine to hum is the condition of the tires that are bumpy or bumpy, which makes the tire tread uneven. When this happens to your vehicle, you will usually hear a hum that seems to be coming out of the engine.
The sound that appears generally occurs when the vehicle is traveling above 60 kph. However, the sound will not last long, it will slowly decrease as the car accelerates at speeds above 100 kph. Lumpy or bumpy tires can usually be caused by a lack of air pressure. When you hit a hole or a gravel road, it usually causes the tires to become bumpy and bumpy.
3. Bearing or axle bearers
Referring to the sound source of the car engine humming next, it may be due to a problem with the bearing or wheel bearing. The sound usually occurs when the car is traveling above 40 kph. Unlike the bump tires, for this one case. When the car is driven faster, the hum in the vehicle cabin will continue to increase. Don’t let this reduce your comfort when driving. When a buzzing sound appears, immediately check it, then repair the damaged component.
4. AC Compressor Problem
A problematic AC stove is one of the causes for the humming sound of a car engine that is felt the most by vehicle owners. It is likely that this also affects the quality of the air conditioner which is not as cold as usual. If this happens to your car, it means that the AC compressor is not in prime condition. Strong suspicion that your AC compressor is worn. Inside the AC compressor there are metal rubbing against each other and will make a humming engine sound. Usually, the buzzing sound will only be heard when the air conditioner is turned on.
When the air conditioner is turned off, the buzzing sound will disappear by itself. Even so, it does not mean that this problem can be ignored.
Especially if the Freon AC condition is blocked, it can cause more severe damage and of course you will spend a bigger pocket too in repairing it.
As a result, when you find the sound of a car engine buzzing. Hurry to the repair shop to fix your car’s AC compressor.
5. Joint Couples Aged
This one device is usually found in cars with rear-wheel drive or 4WD. The coupling joint serves as a liaison between the coupling pole and the axle. When there is a problem, it makes the car engine hum. For information, the coupling joint also functions as a shock absorber when the power from the engine is transferred to the wheel drive. If the damper has started to weaken, it will usually make a hum when the car is driving at 60 km / hour. In addition, it usually causes vibrations that the driver can feel.
