How are flood-damaged vehicles classified?

[IsabellaMarie]

Flood-damaged vehicle classification is as follows: 1. Grade D: If there is only slight water ingress in the vehicle, with mildly damp carpets, and the vehicle was parked statically. Some vehicles have lower engine air intakes where water can enter the intake tract, resulting in Grade D flood damage. 2. Grade C: Water ingress into control modules (ECUs) under seats, yaw rate sensors, or sudden engine stalling during water wading results in Grade C flood damage. 3. Grade B: Flood damage is classified as Grade B if the vehicle stalls during water wading and is either restarted once or twice. 4. Grade A: If the vehicle requires engine overhaul after water wading, interior carpet removal for drainage, or transmission (TM) water ingress, the flood damage is classified as Grade A. 5. Grade S: If water levels rise above the dashboard, the flood damage is classified as the supreme Grade S.
