Who should be responsible for the car crash and death caused by the heavy rain that caused the water to flow back into the garage?

Legal analysis: first, we must find the cause of the accident before we can determine who should bear the responsibility. Defining whether it belongs to the developer's responsibility mainly depends on whether the drainage system of residential areas and underground garages is built in accordance with national standards and whether the drainage design and construction are standardized. If it is because the drainage design or construction of the underground garage is improper during the construction, which leads to drainage problems in the use process and causes property losses, then the owner may require the developer to bear certain liability for compensation according to relevant laws.

Secondly, there is no mandatory legal provision on the responsibility of the property management party in sudden natural disasters. This is mainly based on the property service contract signed by the owner and the property management party to judge whether the property management has fulfilled its due obligations. Property management has obvious dereliction of duty, can be held accountable. If the property management can't avoid losses even if it does its duty, it doesn't need to bear the responsibility. After the rainstorm, it is generally a period of high incidence of disputes between owners and property. Many owners think that the owners should bear part of the responsibility, while the property management company thinks that the rainstorm is force majeure. The rainstorm itself is an external cause, but in the process of raining, the property management company, as a professional property management department, should be able to foresee the situation that the rainy season may endanger the interests of the owners. The parties can foresee it, but due to negligence, they failed to foresee it or tried their best to stop it, so the defense of force majeure cannot be established. The property management company shall formulate an emergency plan for sudden accidents, and notify the owner to do a good job in safety prevention when such accidents may occur, such as notifying the owner to move the car parked in the underground garage to a safe place when there may be heavy rain, so as to reduce or prevent the loss of the owner's property. As long as the property management company has fulfilled the corresponding responsibilities and obligations in accordance with the contract, the owner cannot ask it to bear the liability for compensation after the accident.
