Will the 4S store replace the new car's headlights if there is water mist?

If the vehicle is still under warranty, you can request the 4S store to replace the headlights. Below is relevant information: 1. Influencing factors: Headlights are not consumables like tires or engine oil. If a new car's headlights have water mist, it must be a quality issue. There is a ventilation and heat dissipation rubber tube at the rear cover position of the headlight structure. If the rubber tube is not properly sealed, water droplets may appear, and in severe cases, water accumulation in the headlight may occur. This problem is most common in winter and the rainy season. 2. Reasons for water mist: If the water mist is slight, it is not a quality issue. Since the working temperature of xenon lamps can reach over 300 degrees, the gas inside the headlight expands when the light is turned off and cools down, creating a pressure difference that draws external water vapor into the headlight, forming the visible water mist. This slight water mist can be dried by turning on the headlights and using the heat from the light to evaporate the mist inside the headlight. Alternatively, placing several more drying packets inside the headlight can help prevent mist formation.
As a new car owner, I found that condensation inside the headlights is quite common. This is usually caused by water vapor accumulation due to loose sealing rings on the lamp covers or significant temperature differences, which often occurs in humid weather with new cars. Regarding whether the 4S store will replace it, it depends on whether it's within the warranty period and if it's caused by manufacturing defects. New cars generally come with a 2-3 year warranty. If your headlights haven't been damaged by collision or modified, and the 4S store confirms it's a quality issue after inspection, they will replace the headlight assembly for free. The process is quick, usually completed within a few days. However, note that if there's minimal condensation that can evaporate on its own, it's not a major issue; but if the condensation is heavy and obscures visibility, don't delay—visit the store promptly to avoid safety risks. I've handled a similar situation myself, and everything went smoothly.
