When the automobile engine support is damaged or has problems, the following problems may be caused:

1. Increase of engine vibration: The main function of engine support is to support and fix the engine. When the engine support is damaged, the engine will lose its stable support, which will lead to the increase of engine vibration and affect the stability and driving comfort of the vehicle.

2. Increase noise and vibration: The damaged engine support cannot effectively absorb the vibration and noise generated when the engine is running, which may lead to the increase of internal and external noise of the vehicle and affect the driving experience.

3. Intensify engine wear: Damage to engine support will lead to additional vibration and impact on the engine during driving, which will aggravate the wear of engine parts and shorten the service life of the engine.

4. Affect the vehicle suspension system: Damage to the engine support may affect the stability and work efficiency of the vehicle suspension system, thus affecting the handling and driving safety of the vehicle.

5. Increase the load of other components: the damage of engine support will lead to the unstable position of the engine, which may make other adjacent components bear additional load and accelerate the wear and damage of other components.

Therefore, once the automobile engine support is found to be damaged or problematic, it should be repaired or replaced in time to ensure the normal operation of the engine and ensure the safety and reliability of the vehicle.
