What causes severe jerking when accelerating in BYD F0?
3 Answers
The reasons for severe jerking when accelerating in BYD F0 are as follows: When there is sludge in the transmission oil, and the sludge circulates within the transmission, blocking the oil passages in the valve body, jerking will occur. Prolonged severe jerking can lead to a series of transmission issues such as overheating, impact, and slippage. More information about jerking is provided below: 1. If severe jerking occurs when accelerating, after completing gear engagement, if the clutch is released directly, the vehicle will stall. When slowly releasing the clutch and pressing the accelerator, if the vehicle speed and gear do not match, it is easy to experience gear dragging, causing the car to jerk forward without stalling. 2. In many cases, transmission jerking, impact, and slippage are not caused by internal valve body damage but by stubborn dirt and impurities inside, especially when dirt and impurities accumulate in the valve body, forming blockages that prevent effective regulation of oil pressure, leading to jerking, impact, and slippage. At the same time, transmission overheating should not be overlooked. According to data from the Automatic Transmission Rebuilders Association: "Over 90% of faulty automatic transmissions are caused by overheating."
I've been driving my BYD F0 for almost ten years, and this issue of jerking during acceleration is quite common, especially in older or high-mileage vehicles. The cause could be irregular ignition due to aging spark plugs or clogged fuel injectors disrupting fuel supply. A dirty air filter can also affect air intake, making the engine respond sluggishly. Some people encounter transmission issues, such as clutch wear, which disrupts power delivery smoothly. I once faced this problem, and it turned out to be a faulty ignition coil—replacing it fixed the issue. I recommend starting with a simple check of the spark plugs and air filter, as it's not costly. If the problem is severe, don't delay; visit a 4S shop to inspect the sensors or ECU system to avoid breaking down midway. Remember, safety comes first when driving. If the jerking is severe, avoid sudden acceleration and slow down to pull over and investigate.
As a small mechanic who's seen plenty of BYD F0 cases in the workshop, throttle hesitation is often related to ignition or fuel issues. Worn-out spark plugs with degraded performance can cause delayed ignition leading to hesitation; clogged fuel injectors causing unstable fuel supply is another possibility. For automatic transmissions, clutch or valve body failures can significantly contribute. Also check the air filter and throttle body - carbon buildup disrupts airflow. A quick OBD scanner check can reveal sensor error codes. The fix isn't complicated - start with replacing spark plugs (cost-effective solution). Without proper tools, consult professional technicians who can perform systematic diagnostics to avoid costly repairs. Safety-wise, this issue may increase fuel consumption or cause stalling - better address it promptly.
