No, it does not. International shipping (especially RoRo) usually takes 30 to 60 days, during which the vehicle is stationary. A dead 12V battery, natural tire pressure loss, and even wiper aging due to temperature differences are all reasonable physical wear during long-distance transport. We strongly recommend that overseas buyers bring a portable jump starter and an air pump when picking up their vehicles at the port.
