Hyundai is recalling 239,000 cars for exploding seat belt pretensioners

> While a specific and exact cause is still unknown, Hyundai did employ a third-party engineering firm, Exponent, to come up with a threat mitigating solution. Ultimately, they identified a micro gas generator inside the pretensioner as the cause of explosion.

> Exponent has created a cap that will secure that micro gas generator and eliminate stress sites that could potentially increase the risk of an abnormal deployment. It should also be noted that the three incidents have only occurred in connection with a crash or collision so there’s no reason to expect these to just go off randomly.
