Can Secondary Ignition After Water Immersion Be Detected?

[AlanAnn]

Generally, it can be detected. Here are the relevant details: 1. No response from the starter: After a vehicle has been submerged, the starter will only react if the engine stalls and is then restarted. If the starter shows no response, it indicates a secondary ignition. Secondary ignition refers to the situation where the vehicle stalls underwater and the key is turned again to ignite the engine underwater. If you have water submersion insurance, whether you can claim depends on whether you attempted to restart the engine or not—no ignition means you can claim, while secondary ignition means you cannot. 2. Engine damage: Typically, if a vehicle stalls in water, there is a 50% chance of engine damage. However, if the engine is restarted after stalling, the engine is almost certain to be 'totaled.' Therefore, whether driving or parked in a residential area, underground garage, or street, never attempt to restart the engine after it has stalled due to water submersion.
