Dirt, sand, pet hair, and even water can work havoc on the battery as well as other fragile parts of the hybrid vehicle. In general, the battery is usually located at the back side of most hybrid vehicles, under the cargo area or even the back seat. Such dirt may enter the cooling system of the battery, thereby clogging it and heating up the battery, which further causes damage to the same.
Furthermore, water can rust the coolant system and other electrical parts, which may cause shorts. This will potentially lead to costly repairs or become a fire hazard. Also, a dirty car is said to attract rodents that are prone to gnaw on soy-based insulation wires. This can cause electrical problems such as stalling, complete failure of the engine, or a fire hazard. Cleaning and maintaining your hybrid car prevents all these and ensures the longevity and safety of your investment in your hybrid vehicle.
