What Causes Severe Jerking at Low Speeds in the JAC Jiayue A5?
1 Answers
JAC Jiayue A5's severe jerking at low speeds may result from the following causes: Engine oil passage blockage: First, focus attention on the engine. If the car experiences jerking while driving, the engine is undoubtedly involved. The engine's ignition, air intake, and fuel injectors collectively determine fuel combustion, which is the power source of the engine. If the air intake volume decreases, ignition weakens, or fuel injection reduces, power will be insufficient, leading to jerking sensations. Transmission oil contamination causing solenoid valve damage: If sludge circulates within the transmission oil and blocks oil passages in the valve body, jerking issues will arise. Over time, this can lead to a series of transmission problems such as overheating, impact, and slippage. Break-in period: During the break-in period of a new car, slight jerking while driving is normal. This is because the vehicle's power output and component engagement are not yet at optimal levels, and the transmission's computer has a self-learning mechanism that continuously adjusts oil pressure for gear shifts.
