A family full of expectations bought the latest model of a home MPV, believing that a high price represents safety. But only three days after picking up the car, on the highway, when Cheng Ye emergency braked, he found the pedal suddenly failed, nearly putting the whole family in danger. After the accident occurred, the 4S shop refused to admit the vehicle problem, instead questioning the owner's operation. Facing prevarication and pressure, Cheng Ye took out the driving records and inspection reports, investigating the truth step by step. Until the review of the same model vehicle was exposed, the hidden problems surfaced, and the 4S shop finally admitted responsibility. A rights defense is not just for compensation, but to make every family's safety taken seriously.
