At what water level is it safe for a car to be submerged?

[JesseRose]

It is generally safe as long as the exhaust pipe does not take in water. If a hose is used to cover the exhaust pipe and no water enters upwards, it should be fine. Below is relevant information: 1. How to determine if there is an issue: Check the air filter to see if water has entered. If no water is found, the water exposure is likely not a major problem. Inspect the interior for water ingress, as water usually enters through the chassis. Also, check the chassis for water accumulation. If possible, lift the car to inspect. Verify the oil level using the dipstick to check for any abnormalities. 2. Post-submersion handling: Water entering the car due to rain may leave moisture in the cabin. Use a hairdryer to dry the seats and other affected areas. If possible, open all doors and let the car dry under the sun, which can also help disinfect the interior.
