What are the most common faults of the Honda Vezel?

[Poppy]

Honda Vezel's most common faults include excessive engine carbon deposits and loud engine noise. Excessive engine carbon deposits: When engine fuel does not burn completely, it can easily lead to carbon buildup. Excessive carbon deposits can cause a decrease in engine power because the carbon deposits adhere to the spark plugs, reducing their ignition capability and resulting in insufficient power, causing the idle speed needle to remain stationary. The solution is to clean the carbon deposits. Loud engine noise: Engine noise can be categorized into cold-start noise and hot-engine noise. Cold-start noise refers to abnormal sounds coming from the engine compartment when starting the car, which disappear automatically after the engine warms up.
