I've driven quite a few cars and fixed some common issues. The rear seat vibration in the Song Plus DMi is quite annoying, mainly caused by suspension system or tire problems. Tire imbalance is the most common issue, often due to unbalanced tires at high speeds or uneven wear; suspension components like aging shock absorbers or loose ball joints can transmit vibrations to the rear seats; loose engine mounts can also cause shaking; problems with the driveshaft can make the rear seats wobble during turns and acceleration; and worn wheel hub bearings, when severely worn, affect stability. I recently encountered a similar issue and went straight to the 4S shop for inspection. The technician used instruments to check tire balance and suspension connections. Regular maintenance is key—check the wheels every 5,000 km, and inspect the suspension during oil changes to prevent worsening vibrations, which can affect ride comfort and even lead to breakdowns. If you're not sure how to fix it yourself, it's best to consult a professional to avoid costly repairs.
I went out with my friends in my Song Plus DMi, and the back seat always felt bouncy up and down, which was really annoying. On the highway, my friend in the back said his butt was getting numb from the bumps. Possible causes could be uneven tire pressure or misaligned wheels, incorrect four-wheel alignment; loose suspension springs or leaking shock absorbers, transmitting vibrations to the rear seats; issues with the drive shafts, making a clunking noise during acceleration; engine mount bolts not tightened properly, allowing vibrations to enter the cabin directly; the shaking is more noticeable on long trips over bumpy roads. It's recommended to first check if the tire pressure is normal—a big difference between front and rear tires can cause shaking. Take a quick look at the suspension for any signs of rust or oil leaks, but don't disassemble anything randomly to avoid damage. If the shaking is frequent, take it to a repair shop immediately—they can use machines to inspect the wheels and drivetrain. After fixing my car, the back seat became much more comfortable. Regular maintenance of tires and the chassis can save you trouble and money. Always perform a safety check before long drives to avoid regrets later.
