What is the reason for the buzzing resonance in Hongguang?
2 Answers
The reason for the buzzing resonance in Hongguang is: the excessive gap between the drive shaft and the rear axle, which is a common issue with Hongguang. Rear-wheel-drive vehicles generally experience this situation. As long as the engine speed is maintained above 2000 RPM during driving or gear shifting, there will be no resonance. Hongguang is a crossover self-developed product launched by SAIC-GM-Wuling, positioned between commercial vehicles and passenger cars. With its smooth exterior design, diversified and practical spacious driving space, perfect balance between power and economy, and strong performance in handling and safety, it has overturned people's traditional impression of commercial vehicles.
I remember one time my Hongguang was buzzing on the highway, which was quite annoying. The cause was most likely tire-related, such as unbalanced tires or slightly deformed rims, which can cause resonance and produce a buzzing sound at high speeds. It could also be due to worn suspension components or uneven brake discs, with the vibrations transmitting to the car body. I suggest starting with the simpler checks: make sure the tire pressure is consistent—too low or too high is not ideal. Then check if the tire tread is wearing evenly, as uneven wear can easily cause vibrations. If you're unsure, take the car to a professional shop for a dynamic balance test or have the axles checked on a machine. This won’t cost much but is very effective. When driving, try to avoid rough roads, and regularly maintain the rims and suspension to prevent the buzzing sound from recurring—safety first, after all. Persistent resonance not only affects driving comfort but may also accelerate wear on vehicle components, increasing repair costs.
