The following are specific reasons for the buzzing noise when the new Emgrand starts: 1. Abnormal friction between the wheel brake disc and brake pads: The noise is caused by abnormal friction between the wheel brake disc and brake pads. 2. Issues with the vehicle's suspension system: The noise may be due to poor performance of related components in the vehicle's suspension system. However, diagnosing noise and sound-related issues in vehicles requires on-site testing and listening to the noise, combined with an analysis of the conditions under which the noise occurs, its characteristics, and its source to make an accurate judgment.

Having run an auto repair shop for years, I've noticed that the Emgrand's starting clunk is a common complaint. The noise is mostly caused by issues in the chassis suspension system, such as worn or loose stabilizer links or aged shock absorber bushings, which shift and produce a clicking sound upon starting. It could also be due to play in the driveshaft's universal joints, creating vibration and noise when engine torque is transmitted to the wheels. Loose brake calipers can cause similar noises. I recommend owners first crouch down to check for obvious damage around the tires, then visit a professional shop promptly for an inspection using a lift to observe any loose chassis components. Ignoring it may worsen the problem, even affecting handling safety during turns. Also, avoid disassembling parts yourself to prevent damaging other components. Regular suspension system maintenance can prevent this issue.

My Emgrand had the same issue, making a clunking noise during startup which really startled me. Initially, I thought the axle was broken, but the mechanic found out it was a loose link in the front suspension. Replacing a small part made it much quieter. It could also be caused by aging shock absorbers or displaced brake pads. Don’t procrastinate like I did—the vibration worsened after a few weeks, so it’s safer to get it diagnosed at a repair shop promptly. Regularly check tire pressure and keep the undercarriage clean, as rough roads can accelerate component wear. These minor tasks cost at most a hundred bucks, saving you from more expensive major repairs. Safety first—startup noises are no small matter.

Starting with a clunking sound warns of potential risks. I understand this often stems from chassis issues such as loose suspension systems, which may interfere with normal driving. It is advisable to stop immediately and check for abnormalities in tires and brake components, contacting professionals if necessary. If ignored, abnormal vibrations might lead to loss of control during emergency maneuvers, endangering passenger safety. For prevention, it is recommended to regularly replace aging rubber bushings.

Annoying noises when starting a family car are frustrating. I understand this is often caused by loose suspension links or aging shock absorbers. To save money, first check the chassis yourself for obvious rust or looseness. Regularly replacing parts can extend the car's lifespan. If the noises persist, it's necessary to visit a 4S store for part replacements to ensure driving safety. Proper doesn't cost much.
