What is the solution to the rear seat resonance in the Song DMI?
4 Answers
Song DMI rear seat resonance solution is to adjust the rear seats. Disadvantages of the Song DMI: The interior is generally acceptable, but the workmanship in some areas is not good, with large gaps at the joints; this car uses a dual-clutch transmission, so at low speeds, the gear shifting is not very responsive, and the jerkiness is quite noticeable—it would be better if it used a 6AT transmission; the vehicle's noise insulation is poor, mainly manifesting as wind noise and tire noise. As soon as the speed increases slightly, noise becomes noticeable inside the car. Advantages of the Song DMI: The space is relatively large, and even when fully loaded, there is no crowding; the power is very strong, and the handling is excellent.
Rear seat resonance in the Song DMI is actually quite common. I encountered it during a long-distance trip – after driving for an extended period, the seats started buzzing annoyingly. There could be several reasons, such as loose seat mounting screws or slight issues with the suspension system. The simplest approach is to do a self-check first: after parking, shake the connection points between the rear seats and the chassis. If you feel any looseness, try tightening the screws with a wrench. If that doesn’t help much, consider adding soundproofing foam or vibration dampening pads to absorb the vibrations. I’ve also found that unbalanced tires can transmit vibrations to the rear seats, so regular wheel alignment is helpful. If all else fails, it’s best to take it to a 4S shop for professional diagnostics—they can use specialized equipment to inspect the suspension and exhaust systems, preventing minor issues from becoming major problems. In short, don’t ignore these small noises; they can affect driving safety and comfort. Addressing them promptly brings much-needed peace of mind.
Rear resonance is usually caused by the fitting issues of body components. As an enthusiast with some car repair experience, I think you can start from several aspects. First, check the fixing points of the seats and floor. If screws are loose or rusted, tightening them can significantly reduce vibrations. Next, inspect the suspension system. The independent suspension of the Song DMI might sometimes cause resonance due to uneven road conditions. Adding some grease or adjusting the position of the suspension links can help. Then, look at the exhaust pipes. Over time, they might loosen and create noise, which can be fixed by applying some soundproofing strips. Don't forget the tires—if they're unbalanced, rotating or balancing them should solve the issue. In daily use, I recommend avoiding full-load driving to reduce extra stress. If you can't fix it yourself, consult a professional repair shop for diagnosis. Don't delay to prevent damage to other components.
I noticed occasional slight vibrations in the rear seats of my Song DMI while driving, especially more noticeable at high speeds, which significantly affects long-distance comfort. This could stem from loose connections between the seats and the car body, or aging suspension components, leading to the transmission of low-frequency noise. Solution: First, simply check the seat base, tighten screws, or add anti-vibration pads, which can be easily purchased on Taobao. From another perspective, adjusting driving habits, such as avoiding stomping on the accelerator on bumpy roads, can reduce vibration sources. If the budget allows, a full-car soundproofing project covering the carpet and chassis can have a significant effect. Remember to perform regular maintenance, including tire and wheel hub checks, to prevent such minor troubles much more effectively.
