What is the reason for the abnormal noise when the Haval H6 accelerates suddenly?

The possible reasons for the clicking noise when the Haval H6 accelerates suddenly are excessive wear of the inner CV joint in the half-shaft or ignition coil failure. Excessive wear of the inner CV joint in the half-shaft: Due to the change in the force point, a certain angle is formed between the transmission and the half-shaft, resulting in abnormal noise from the vehicle. The half-shaft should be replaced directly. Additionally, the main reason for excessive wear of the inner CV joint is often due to the failure of the owner to replace the damaged dust cover on the half-shaft in time. Therefore, if the dust cover is found to be broken and leaking oil, it must be replaced immediately; otherwise, the consequences will outweigh the benefits. Ignition coil failure: Ignition high-voltage wires rarely have issues, but the ignition coil and spark plugs are considered wear-and-tear parts. When the performance of the spark plugs declines or inferior-quality spark plugs are used, it can lead to symptoms such as weak acceleration or shaking during acceleration.
My Haval H6 sometimes makes a clicking noise during rapid acceleration, which is quite annoying. The reasons may involve several aspects. One is engine-related issues, such as a defective ignition system causing uneven air-fuel mixture and knocking during rapid acceleration. Another could be a loose drive belt or a faulty tensioner, which produces obvious squeaking sounds. Additionally, aging or loose chassis suspension components like shock absorbers or control arms may rattle due to vibration during acceleration. Poorly fixed brake calipers can also cause noise. I suggest first trying to identify the source of the noise—if it's from the front, focus on checking the belt and spark plugs; if it's from the rear, inspect the suspension and drive shaft. Don’t delay—take it to a professional repair shop promptly to prevent minor issues from escalating into major engine or transmission overhauls, ensuring peace of mind every time you drive.
The Haval H6's abnormal noise during rapid acceleration is an issue I've encountered several times, primarily stemming from power transmission and friction components. For instance, excessive spark plug gap or aging can cause ignition issues and popping sounds during rapid acceleration; a loose or worn belt system often produces squeaky friction noises; deteriorated suspension bushings or loose control arms can lead to vibration and impact sounds during acceleration; exhaust system leaks may also result in hissing noises. When addressing this, don't be careless—first, try to locate the direction of the noise by listening carefully. If the noise comes from the engine side, focus on checking the ignition system and belts; if it's from underneath the car, pay attention to the suspension and differential. Develop a habit of regular maintenance—during oil changes, simultaneously inspect belt tension and suspension fastenings to maintain stable vehicle condition and prolong its lifespan.
