Total uproar in the United States as reported by the US National Highway Transportation Safety Administration (NHTSA), Hyundai recalls 239,000 vehicles. Hyundai recalls its vehicles due to a massive failure in seat belt pretensioners that could cause them to explode and injure passengers.
The failure occurs in some Accent, Elantra, and Elantra Hybrid models concentrated in the seat belt pretensioners, whose operation is elementary in a road accident.
This element works as a pyrotechnic mechanism, and when the impact sensor detects an accident, it produces a minor detonation, and one can notice the spread of gas, which, when expanded, starts a mechanism anchored to the belt and tightens it. And once tensioned, it is progressively released to control damage to the occupant. All this happens in a tiny fraction of seconds.
However, after the report of three accidents (two in the United States and one in Singapore), they realized that sometimes it is possible that we cannot contain the explosion of the pretensioner, which could send metallic elements inside the passenger compartment with the danger of harming the occupants.
According to the US NHTSA, the call for review includes 61,000 Hyundai Accent from 2019-2022, 166,000 Hyundai Elantra 2021-2023, and 12,000 Hyundai Elantra Hybrid 2021-2022.
Before July 15, Hyundai will notify all of its customers. All owners who are informed must take their vehicle to their respective dealership. They will review the safety pretensioners and incorporate a special cover to ensure that the gas micro-generator of the pretensioner is safe.
To find out if units have this problem at MT La Tercera in Chile, they consulted Automotores Gildemeister about the said fault. They said they could not yet comment on this issue because the factory had not notified them.
