A recent incident involved a frustrated owner of a premium 7-seater vehicle threatening to burn his car on Independence Day after his sunroof exploded while driving on an open highway.
Sunroof Explosion – Main Reasons
In a recent case in Haryana, the sunroof of a Toyota Innova Hycross exploded during a journey. Such incidents are reported more frequently in the United States. But what causes these sunroof explosions?
Sunroofs, a popular feature in cars, can explode for several reasons. Manufacturers point to two main causes: environmental factors like temperature changes or debris hitting the glass, and accidental damage such as improper tempering or contaminants in the glass. However, car owners often suspect a safety defect or vehicle design flaw, believing that the compact design of some vehicles puts extra stress on the glass, causing it to shatter.
In 2021, the National Highway Traffic Safety Administration (NHTSA) closed an investigation into spontaneous sunroof glass shattering, finding insufficient evidence of a safety-related defect and no serious safety risks identified by federal officials.
Sunroof Explosion – India Case
Recently, a Toyota Innova Hycross experienced a sunroof explosion. According to the driver, the incident occurred while traveling on the Panipat highway, with dash cam footage capturing the frightening event. Although the service center repaired the sunroof, the car began accumulating moisture on its interior and exterior. The exact cause of the explosion is unknown, but it is suspected to be related to temperature fluctuations. The owner believes it to be a manufacturing defect and is demanding answers from Toyota Kirloskar Motors. Frustrated by the situation, he has threatened to set the Innova Hycross on fire this Independence Day.
