How to Solve the Excessive High-Speed Noise Issue in Hongqi HS5?
4 Answers
Hongqi HS5's excessive high-speed noise can be addressed by installing soundproofing cotton on the engine hood, fenders, and inner side of the doors. Below are specific details about the Hongqi HS5: 1. Technology: The Hongqi HS5 is an SUV that adheres to the concept of new noble refinement. It is equipped with an active braking system that can detect the distance between the vehicle and the vehicle (or pedestrian) ahead in real-time. When a potential collision is detected, the system automatically applies the brakes to prevent or mitigate the impact. 2. Power: The Hongqi HS5 features a simple interior design outlined with smooth lines and comes with a 12.3-inch integrated full LCD color display. It is powered by a 2.0L turbocharged engine with a maximum horsepower of 224, a 6-speed AT transmission, a maximum power output of 165W, and a maximum torque of 340N/m.
I remember when I first bought the Hongqi HS5, the noise on the highway was indeed quite loud, affecting my driving concentration. Most highway noise is caused by wind noise and tire sounds. Worn tire treads or unstable tire pressure can increase rolling noise, so check your tire condition and replace them with quiet-type tires if they're aging. For wind noise, aging door seals can easily cause air leaks. You can replace the seals yourself or add some soundproofing strips at a low cost. If the soundproofing cotton in the engine compartment is loose, it can also generate noise—try opening the hood and tightening the bolts. Safety comes first; excessive noise can be distracting. It's best to have a mechanic check the vehicle's sealing and soundproofing during regular maintenance, rather than waiting for issues to arise. This is crucial for driving safety.
Regarding the noise issue when driving the Hongqi HS5 on highways, I believe there are several common causes from different perspectives: wind noise could be due to aging window seals or side mirror design issues; tire noise stems from tire type, air pressure levels, or tread wear; engine noise might result from loose protective plates or exhaust system abnormalities. It's recommended to first identify the direction of the sound—if it's a howling noise, focus on checking the rubber seals of doors and windows; if it's a low rumbling sound, examine tire pressure and wear condition, and consider switching to low-noise tires if necessary; if it's an engine humming sound, inspect the protective plate fastening. Additionally, vehicle aerodynamics also affect noise levels, so avoid opening windows at high speeds. For sound insulation, consider installing engine hood insulation cotton or wheel arch liners yourself, which can significantly improve noise levels at a controlled cost of around 100 yuan.
A friend of mine who drives a Hongqi HS5 also reported excessive noise, and his solution was quite straightforward. He started with the tires, maintaining the recommended tire pressure—too high or too low increases noise—and regularly cleaning small stones stuck in the treads. For the door seals, he either cleaned or replaced them, buying a set from Taobao and installing it himself. He also made a habit of opening windows to check for air leaks, using Vaseline to temporarily lubricate the seals if issues were found. On highways, he noticed that using the air conditioning increased wind resistance and noise, so he adjusted the fan speed or switched to recirculation mode. Prevention is better than repair, so he reminds the service shop during maintenance to thoroughly inspect the suspension and sound insulation systems to avoid major issues.
