Is Severe Engine Vibration Normal When the Lavida's Air Conditioning is On?
2 Answers
Severe engine vibration when the Lavida's air conditioning is on is not normal and may be caused by excessively low idle speed. Overview: The automotive air conditioning system (air-conditioning-device), commonly referred to as car air conditioning, is used to regulate and control the temperature, humidity, air cleanliness, and airflow within the vehicle cabin to optimal conditions. Function: Car air conditioning provides drivers with a comfortable riding environment, reducing travel fatigue, and creates favorable working conditions to ensure driving safety. The automotive air conditioning system typically includes cooling devices, heating devices, and ventilation devices.
I've driven the Lavida and felt severe engine shaking when the AC is on, which is definitely abnormal. I remember my own car is a 2018 Lavida. Every time the AC starts, the compressor increases the load, causing slight vibrations. But if the whole car shakes like a sieve, then you should be alarmed. Common causes include aging spark plugs, excessive engine carbon buildup, or worn-out engine mount rubber parts leading to failed damping. The Lavida is equipped with a small 1.5L engine, which is inherently sensitive. When the AC load increases, unstable idling becomes apparent. The last time I encountered this issue, I took it to the 4S shop for inspection and replaced the ignition coils and spark plugs, and it was fixed immediately. Don't ignore it—this shaking could lead to a sudden spike in fuel consumption or even stalling midway, which is a serious safety concern. Regular checks and early repairs save money and hassle. Otherwise, delaying repairs could cost you thousands more for an engine mount replacement later.
