The invention discloses an automobile chassis system fault early warning method and system, and relates to the technical field of vehicle chassis, the fault monitoring system comprises a rotation angle sensor, a wheel speed sensor, a yaw velocity sensor, a data processing module, a storage module, a calculation module and an early warning module, the fault monitoring system can be matched with an existing electrical architecture, a new structure is not needed, and the fault early warning system is convenient to use. Potential faults of the chassis system can be found in time and early warning can be carried out, so that greater safety risks of the vehicle are avoided; according to the fault early warning method, by analyzing the relation between the vehicle lateral response and the vehicle steering state, whether a chassis system has potential faults or not is judged, whether the vehicle has the chassis faults or not is calculated and judged through steering sensitivity parameters, the current situation is fu
