Why does the Haval F7x experience jerking while driving?
2 Answers
The reasons why the Haval F7x experiences jerking while driving are as follows: Engine oil passage blockage: The oil passage refers to the engine oil and fuel lines of the car. Blockage in the oil passage can lead to various issues, such as unstable idling during driving, engine shaking and vibration, and weak acceleration. Insufficient or deteriorated transmission fluid: Without the lubricating effect of transmission fluid, the jerking sensation during gear shifts increases significantly. Driving in winter becomes particularly uncomfortable due to rough gear changes. Releasing the clutch too quickly when starting: This skill is often the hardest for beginners to master, frequently resulting in stalling or body jerking when starting. Additionally, releasing the clutch too quickly during gear shifts can easily cause the car to stall, which not only damages the vehicle but also makes driving very uncomfortable.
I've been driving a Haval F7x for three years, and the jerking sensation at low speeds or during acceleration is particularly noticeable, making the car lurch forward annoyingly. This car uses a dual-clutch transmission, which might be an inherent design issue—problems often occur during frequent gear shifts in low temperatures or traffic jams. Alternatively, the transmission fluid could be too old or insufficient, affecting lubrication. On the engine side, excessive carbon buildup on the spark plugs causing unstable ignition or a clogged air filter restricting airflow can both lead to power interruptions. Also, the electronic control module software might be outdated and need an upgrade. I remember last winter, the jerking was worse, but warming up the car for a few minutes before driving helped alleviate it. Using higher-quality gasoline can also reduce this issue. From a safety perspective, don’t delay repairs—sudden power loss at high speeds would be extremely dangerous. I recommend first visiting a 4S shop to scan for error codes and identify the root cause before taking further action.
