What Are the Main Symptoms of Car Malfunctions?
1 Answers
Car malfunction symptoms are mainly categorized into abnormal noises, unstable driving, failure to start, and inability to move. Here is some extended information about abnormal car noises: 1. Engine Abnormal Noises: Engine abnormal noises mainly include noises during startup, noises when the engine is cold, noises when the engine is hot, noises at idle, and noises at high engine speeds. Different noises under different conditions indicate faults in different components. 2. Transmission Abnormal Noises: Transmission abnormal noises are categorized into noises during startup, noises during gear shifting, noises in specific gears, and noises under load and no-load conditions. For example, noises during gear shifting may be caused by the clutch friction plate of that gear becoming too thin due to prolonged use, resulting in excessive clearance and impact during shifting. 3. Suspension Abnormal Noises: Suspension abnormal noises mainly come from the suspension's control arms, tie rods, and various upper and lower ball joints, which produce clicking sounds when there is clearance. Wheel bearings and tires sometimes produce humming sounds. These noises occur on uneven roads or when turning the steering wheel. For example, if there is a clicking sound from the lower part of the car when quickly turning the steering wheel left and right while the vehicle is stationary, it may indicate clearance in the tie rod ball joint, which requires professional inspection.
