What are the possible reasons for severe engine vibration in the Elysion?
2 Answers
Possible causes for severe engine vibration in the vehicle may include engine misfire, excessive carbon buildup, tire pressure issues, or problems with the chassis suspension. Below is relevant information: 1. Elysion exterior: The front grille area has slightly increased, with changes in the internal trim design. The lower bumper features more design elements and incorporates a horizontal chrome trim. The headlight assembly retains its original appearance but adds blue accents internally to better align with its hybrid positioning. 2. Elysion interior: The interior continues the classic design, offering good visibility and space performance. Many physical buttons are retained and neatly arranged within easy reach.
When my Elysian's engine shakes severely, I remember during the last maintenance visit, the technician found that it might be due to worn spark plugs or faulty ignition coils. Over time, the electrodes of spark plugs wear out, causing unstable ignition and resulting in engine vibration. If the ignition coil fails, it won't deliver electricity to the spark plugs properly, especially noticeable during cold starts or acceleration. Additionally, the fuel system shouldn't be overlooked—clogged fuel injectors due to carbon buildup can lead to uneven air-fuel mixture, preventing the engine from running smoothly. I've also noticed that a dirty mass air flow sensor can affect air intake, contributing to shaking issues. Mechanically, worn engine mounts are a common cause, especially for heavier MPVs like the Elysian, where mounts are more prone to aging, with vibrations being particularly noticeable at idle. Ignoring these issues can damage internal engine components and increase repair costs. It's recommended to first check the simplest components like spark plugs and mounts, then gradually move to more complex parts, preferably at a professional shop using a diagnostic tool to read fault codes.
