What Causes the Abnormal Noise When Accelerating in Lavida?

[ValeriaDella]

Lavida makes abnormal noise when accelerating due to the following reasons: Abnormal noise from the fuel pump motor: When there is wear or impurities inside the fuel pump motor, abnormal noise occurs when accelerating. This issue requires replacing the fuel pump. Abnormal noise from the throttle: Modern throttles are electronic, and the motor controls the opening and closing of the throttle valve. When the motor gears wear out, insufficient engagement causes abnormal noise. Excessive carbon deposits or sludge in the throttle can also lead to abnormal noise. Cleaning the throttle may resolve the issue, but if the motor is damaged, the throttle needs to be disassembled to replace the servo motor. Abnormal noise from the accelerator pedal: Poor lubrication of the accelerator pedal bearing can cause abnormal noise. You can apply grease to the bearing for lubrication.

I also encountered abnormal noise when stepping on the accelerator while driving my Lavida. This could be due to loose or worn components in the engine section. For example, an aging fan belt may cause squeaking sounds when slipping during acceleration; or loose engine mounting bolts may generate noise from vibration during acceleration. Additionally, damaged suspension components like shock absorber bushings may produce rattling noises when accelerating. I think it's best to check the belt and mounts for cracks or looseness. Regular maintenance can prevent these issues, such as inspecting the chassis every 5,000 kilometers to ensure all parts are properly tightened. Ignoring abnormal noises may lead to more severe engine damage and affect driving safety. Therefore, once unusual sounds are heard, it's advisable to promptly visit a professional repair shop for diagnosis and replacement of relevant components to prevent minor issues from escalating into major troubles.

My Lavida sometimes makes strange noises when accelerating, which is likely related to the suspension system. For example, worn suspension ball joints or links may produce squeaking sounds under acceleration force; or loose brake calipers could resonate and create noise when pressing the accelerator. I recommend first checking if the tire pressure is abnormal, as excessively low pressure can increase noise during acceleration. Additionally, inspect whether the chassis bolts are tight, as many strange noises originate from minor looseness caused by long-term vibration. The solution is to have a comprehensive inspection at an authorized 4S dealership, where they can quickly diagnose the issue. Developing regular maintenance habits is crucial—don't wait until the noises become severe before repairing.

While driving the Lavida, I noticed a buzzing noise when pressing the accelerator, which is usually an electronic component issue. For example, a faulty accelerator pedal sensor can cause incorrect acceleration signals that trigger noise; or a carbon-clogged mass airflow sensor may affect air intake and produce squeaking sounds. This indicates we should clean the throttle body and ensure proper connections in the electronic system. Safety comes first—abnormal noises can distract attention, so it's best to get it checked early.
