What are the causes of noise in the new MG 5?
3 Answers
The causes of noise in the new MG 5 are tire noise, wind noise, and engine-generated noise. Tire noise: Most tire noise occurs during vehicle movement, formed by the compression of air inside the tire tread gaps and the external air, creating noise. Additionally, when driving on rough roads, noise is generated by vibrations in the tire body and tread, as well as noise from the road surface. This can be reduced by switching to quiet tires or adding tire liners. Wind noise: The primary noise during car movement is wind noise. This noise is caused by pressure changes due to airflow separation during vehicle movement, resonance of airflow around the vehicle, and noise from gaps in the car body. Engine-generated noise: During cold starts, the engine noise of many car models is quite noticeable. Noise enters the cabin through the underbody guard, firewall, and fixed connectors. These noises mainly include intake noise, airflow noise, noise from certain engine components, and noise during startup while driving.
When driving my new MG5, I keep hearing various buzzing noises, especially noticeable on the highway. I suspect it's mostly wind noise—the door seals aren't tight enough, so wind rushes in and creates noise. The tires are another issue; the factory-fitted ones wear out quickly and start making a rustling sound after a few thousand kilometers. Then there’s the suspension system—it gets louder over bumps, possibly due to worn shock absorbers. As for the engine, there’s occasional unusual noise during acceleration, sometimes caused by unstable idling. I recommend regular checks on tire balance and replacing the seals to avoid noise affecting your driving mood. Don’t overlook these—timely fixes can also extend your car’s lifespan.
As a mechanic who frequently works on cars, I've seen many new MG5 owners complain about noise issues. The most common sources are minor faults in the engine compartment, such as loose or worn drive belts, which can produce squeaking sounds at idle. Then there's the suspension system—if the shock absorbers are damaged, you'll hear a loud thud when going over speed bumps, which transmits directly into the cabin. Tire noise is another major culprit; unbalanced tires or insufficient tire pressure can be unbearably loud at high speeds. Loose interior components can also contribute, such as an unsecured dashboard that rattles when vibrating. Don't ignore these issues. I recommend taking the car to a professional shop for inspection. Replacing a belt or adjusting the suspension can make a big difference and prevent the problem from worsening.
