Hyundai is recalling more than 120,000 Tucson crossover models in South Korea because the airbag assembly may come loose from its mounting on the steering wheel.

The carmaker already announced at the weekend it would recall nearly 140,000 Tucsons in the US because of the same issue. South Korea's transport ministry said the domestic recall affects Tucsons produced from 2011 to 2013.

Hyundai said that during assembly, it was possible the two bolts attaching the driver's airbag module to the steering wheel may not have been properly tightened, according to documents filed with the US National Highway Traffic Safety Administration.

The airbag module might become detached from the steering wheel although there had been no reports of accidents or injuries as a result of the defect, the carmaker added.
