How to solve the loud noise problem of Wuling Hongguang S?

Solutions for the loud noise problem of Wuling Hongguang S: You can install some high-grade sound-absorbing foam materials on the engine cover, which can not only suppress the vibration caused by the hood but also absorb a large amount of noise. The Wuling Hongguang S is a crossover self-developed product between commercial vehicles and passenger vehicles launched by SAIC-GM-Wuling based on the Wuling Hongguang model. The car has a length, width, and height of 4390 mm, 1660 mm, and 1750 mm respectively, with a wheelbase of 2720 mm. In terms of appearance, the Wuling Hongguang S features striking eagle-eye crystal diamond headlights and feather-shaped crystal diamond front fog lights, further enhancing the vehicle's sense of grade. The two powerful lines bulging on the engine hood give a strong sense of visual strength.

I also encountered loud noise issues when driving the Wuling Hongguang S before, which was quite annoying. The most common causes are old tires or incorrect tire pressure, so I first checked the tire pressure and adjusted it to the standard value. If the tires are severely worn, replace them with new ones or rotate the wheel positions. Engine noise should not be ignored either—check if the engine oil needs to be changed or topped up, and clean out any accumulated dust in the engine bay, which can reduce a lot of noise. For the chassis, loose suspension bolts or failed shock absorbers can also cause creaking sounds. Try tightening them yourself or adding lubricant. When driving, avoid accelerating too aggressively—maintaining a steady speed can make the ride quieter. Excessive noise might indicate other hidden issues. Later, I added some soundproofing strips to the door edges and hood, which I bought online for just a few dozen yuan, and the overall noise level improved significantly. Remember to perform regular maintenance—don’t delay. Safety comes first, and spending a little money can save a lot of hassle.

My Wuling Hongguang S noise issue was resolved from a maintenance perspective. Before each drive, I make it a habit to check tire pressure and wear. If the pressure is off, I adjust it immediately, and if the wear is severe, I replace the tires. I also empty the trunk to prevent items from rattling. For maintenance, I regularly change the oil and filters, and lubricate the chains—these basic tasks save time when done myself. When the noise is loud, I also consider wind noise; driving steadily at lower speeds on highways can significantly reduce the sound. As the car ages, the suspension system is prone to issues, so I had a friend help check the shock absorbers and chassis, tightening any loose screws. If the problem persists and becomes bothersome, I recommend a professional inspection. Spending a few hundred on soundproofing modifications works wonders, making driving much more comfortable.

Driving a Wuling Hongguang S, I figured out how to fix the increased noise myself. First, check the tires—are the tire pressures normal? Adjust if uneven; if the treads are worn out, replace them with affordable alternatives. Clean the engine area and add engine oil—it's cost-effective and simple. Clear out any clutter in the trunk to prevent rattling. Add sealing strips to the door gaps, which can be bought online for just a few dollars. Tighten the chassis screws yourself and lubricate the shock-absorbing parts. These are all low-cost fixes, so there's no need to rush to a repair shop. When driving, maintain steady throttle control and avoid sudden acceleration—the noise will naturally decrease. Inspect carefully, and the issues will be easier to identify.
