What is the problem with the engine vibration of the Axela?
2 Answers
It may be caused by a problem with the spark plugs. Introduction to the Axela: The Mazda3 Axela is a car produced by Changan Mazda. It is the third model to adopt the new-generation "SKYACTIV" technology and the "KODO—Soul of Motion" design theme, and it made its debut at the 2014 Beijing Auto Show. Configuration of the Axela: This model is equipped with two SKYACTIV-G gasoline engines: the "SKYACTIV-G-1.5L," which was introduced to the Chinese market for the first time, and the high-efficiency "SKYACTIV-G-2.0L." Based on an advanced human-machine interface that prioritizes driving safety, this model is the first to feature the "MZD Connect" Mazda Connect system. The vehicle's configuration consistently reflects a technological and user-friendly driving experience.
I've driven the Mazda3 Axela for three years and encountered similar issues. Engine shaking is usually related to several areas. The most common cause is severe carbon buildup in the engine, especially in direct injection vehicles where carbon tends to accumulate on the back of the valves, leading to uneven air-fuel mixture. During my last maintenance, the mechanic had me clean the throttle body and fuel injectors, which significantly reduced the shaking. Worn spark plugs are another common reason - the factory iridium spark plugs need inspection around 40,000 km. Deteriorated engine mounts can transmit vibrations into the cabin, especially noticeable during cold starts. If shaking worsens when the fuel tank is down to 1/4, it might indicate a clogged fuel filter. I recommend reading the trouble codes first - if it shows multiple cylinder misfires, try switching to 95 octane fuel at a different gas station.
