What causes the rattling noise in the Changan CS75 when driving on bumpy roads?
2 Answers
Changan CS75 produces rattling noises on bumpy roads due to loose fasteners on the plastic control panel. The noise can be eliminated by removing and cleaning the connecting panel. Taking the 2021 Changan CS75 Glory Million Edition 280T Manual Elite model as an example, it is equipped with a 1.5T turbocharged engine delivering a maximum power of 131kW and peak torque of 265Nm, paired with a 6-speed manual transmission. The vehicle features MacPherson strut front suspension and multi-link rear suspension, with dimensions of 4650mm(length)×1850mm(width)×1715mm(height), a wheelbase of 2700mm, and maximum horsepower of 178PS.
I've driven quite a few cars, and bumpy rattling noises are quite common, especially in SUVs like the Changan CS75. In my friend's car, we encountered a similar situation, which turned out to be aging and loose bushings in the suspension system, causing squeaks when going over bumps. It could also be due to worn shock absorbers or issues with chassis components, such as unstable stabilizer bar connections. When checking, you can start by shaking the wheels or pressing down on the body to see if there's any noticeable looseness. If the noise is near the wheels, it's best to take it to a professional shop for a comprehensive chassis inspection. Usually, try to drive smoothly on the road and avoid rough terrain to reduce component wear. Remember to address the issue promptly, as prolonged neglect can affect suspension safety.
