Car has manufacturing Defect in AC which they are not accepting

We chose the Honda Amaze (3rd Generation) for its strong engine performance, refined design, spacious cabin, and practical features. With 6 airbags and decent safety equipment, it seemed to be the perfect fit for our family. However, during this monsoon season, I encountered a serious windshield fogging issue. Despite trying all the usual methods to clear the fog, the problem persisted. On closer inspection, I realized that the AC vent directed at the windshield has a continuous airflow, even when the knob is set to the front flow position. I have raised this complaint twice and even left my car at the service workstation on both occasions. Unfortunately, no solution has been provided so far, and the company has not accepted this as a fault. To validate further, I checked other new Amaze cars at the sales office and found the same issue present across the model. Interestingly, this problem does not exist in Honda City, which suggests it may be specific to the Amaze’s design. This fogging issue directly affects visibility and safety while driving in rains, making it a critical concern. Despite Honda’s reputation for reliability and customer trust, this matter remains unresolved. Please let me know if any other owner is also facing the same issue.
