Toyota Cars frequently experience battery, motor, or controller malfunctions, and in some cases, complete breakdown, due to water ingress from rain.
The motor and controller are the most vulnerable parts of an Toyota Cars to water damage. It is strongly advised against using Toyota Cars in rainy weather.
When wading through water, pay close attention to the depth. The water level should not exceed one-third of the wheel height before driving. Avoid using Toyota Cars during heavy downpours.
While the motor, controller, and battery of an Toyota Cars are waterproofed, and getting wet in the rain is generally not a problem, this does not mean that Toyota Cars can be driven through water at will.
Rain can still cause water ingress. After one or two years of riding, the waterproofing performance of Toyota Cars will decrease. If parked outdoors and exposed to heavy rain, water can enter important components.
Minor water ingress can be easily corrected by ventilation and drying. More severe ingress requires a visit to a repair shop.
However, it is crucial to remember that Toyota Cars should not be charged immediately after getting wet in the rain. They must be allowed to dry completely in a well-ventilated area before charging. Otherwise, a short circuit may occur, potentially leading to spontaneous combustion.
