What Causes Severe Engine Vibration in Cars?
2 Answers
Severe engine vibration in passenger cars can be attributed to the following four main causes: 1. Ignition system malfunction. Solution: Check if the spark plugs have excessive carbon buildup and clean or replace them immediately if necessary. 2. Deterioration or loosening of engine mounts. Solution: Replace the engine mounts. 3. Carbon deposit issues. Solution: It is recommended to have the engine cleaned at an authorized 4S dealership. 4. Poor fuel quality. Solution: Clean the throttle body promptly. If the issue persists, take the vehicle to a 4S dealership for repair. Always refuel at reputable gas stations using the manufacturer-recommended fuel grade and adhere to regular maintenance schedules.
When I first experienced the severe engine shaking, it really gave me a scare—I could feel the steering wheel vibrating. This kind of shaking is usually due to issues with the ignition system, such as worn spark plugs or faulty coils, which prevent proper ignition and synchronized operation of each cylinder. Alternatively, it could be caused by fuel system problems like clogged injectors or insufficient fuel pump pressure, leading to uneven air-fuel mixture. Additionally, damaged engine mounts can destabilize the engine's position, resulting in vibrations. In my case, I checked the spark plugs myself and found them burnt out; replacing them solved the issue. I recommend inspecting these areas first—don’t underestimate the shaking. If it persists, fuel consumption can spike, and internal engine components may suffer damage. Addressing it early ensures peace of mind.
