New car original LED headlight fogging water intrusion rights protection case

In March 2024, Mr. Chen, a Guangdong car owner, purchased a new car of a certain brand. He discovered that the car’s LED headlights frequently fogged up due to water ingress during rainy days, affecting nighttime illumination. Mr. Chen repeatedly visited the 4S dealership for repairs, but the staff refused to repair or replace the car, claiming that “minor fogging of the LED headlights is a normal physical phenomenon and does not affect operation.” Mr. Chen consulted the vehicle’s warranty manual and found that it clearly stated that “water ingress to the headlights is covered by the warranty.” He then complained to the local Consumers Association. The Association investigated and confirmed a quality issue with the headlight’s sealing strip. The 4S dealership ultimately replaced Mr. Chen with new headlights and compensated him with three basic maintenance services.
