Will the Engine Make a Buzzing Sound if the Engine Mount is Broken?

If the engine mount is broken, the engine will not make a buzzing sound, but it will vibrate, and the vibration will be more noticeable inside the car. If the engine mount is damaged, it needs to be replaced immediately; otherwise, it will affect the ride comfort of the vehicle. Engine mounts are made of rubber, so they can wear out over time. All vehicles have engine mounts located where the engine connects to the frame. They help absorb engine vibrations, preventing them from being directly transmitted to the vehicle body. If engine vibrations are directly transmitted to the body, it will negatively impact ride comfort. When purchasing engine mounts, always opt for original equipment manufacturer (OEM) parts and have them replaced by professionals at a specialized shop using the proper tools.
When my car's engine was making a humming noise, I also thought it might be a loose belt or a faulty water pump. But last time when the engine mount was damaged, I did hear that kind of humming sound because the engine vibration increased. The engine mount is the rubber pad that secures the engine. When it's broken, the engine becomes unstable and suspended, causing it to hit the body or other parts, resulting in the humming noise. That time, while driving, the noise from the engine compartment suddenly became louder, and I could feel the steering wheel vibrating intensely. After stopping to check, I noticed the engine was visibly bouncing up and down at idle. After replacing the engine mount, the issue was resolved. However, the noise isn't solely indicative of an engine mount problem—similar sounds can occur due to belt aging or exhaust leaks. So, when you hear a humming noise, a comprehensive inspection is still necessary.
