A prolonged factory strike at Hyundai-Kia factories in South Korea could mean that US dealership inventory of certain vehicles, such as the South Korea-built Hyundai Accent and Kia Soul, could dry up in the coming months, depending on the length of the strike, reports Cars.com's blog, Kicking Tires. The two brands together rank sixth in US sales and fifth in global sales.

Kicking Tires gives fascinating insight into how a production stoppage in South Korea might affect vehicle sales in the US, considering Hyundai-Kia has two factories in the US that build the Kia Sorento and Optima/Optima Hybrid, and the Hyundai Elantra sedan/coupe/GT, Sonata/Sonata Hybrid and Santa Fe/Santa Fe Sport. The only one of these vehicles that's built solely in the US is the Kia Sorento, with the rest of them sharing production with South Korea.
