Factory suspension

Hyundai Motor to halt plant for a week; Kona, IONIQ5 affected

South Korea’s top automaker Hyundai Motor Co. will halt its main plant in Ulsan for a week due to a component supply disruption, the latest sign that a global shortage of automotive chips is putting carmakers under increasing pressure.

Hyundai’s sister firm Kia Corp. has also decided to adjust its operations at its plant in Hwasung, Gyeonggi Province, by canceling overtime in April.

According to industry officials on Mar. 29, Hyundai Motor will halt the Ulsan Plant 1 from Apr. 5 through Apr. 13. The suspension marks the first time the automaker has stopped its operations since it temporarily shut the factory in February 2020 due to an inventory depletion of wiring harnesses.

The halt will affect the production of some 6,000 units of the compact SUV Kona and 6,500 units of the IONIQ 5, the first model under its standalone electric vehicle sub-brand.

Hyundai is known to be suffering from a short supply of auto chips used in cameras for the Kona SUV. The company is also having difficulty securing a component, the PE module, for the IONIQ5 from its auto parts-making unit Hyundai Mobis Co.

The component supply disruption at Hyundai comes after US auto giant General Motors Co.’s Korean unit slashed its production rates last month for similar reasons.


The disruptions reflect the auto industry’s increasing reliance on the technology provided by semiconductors.

With the rising popularity of smart cars such as autonomous driving vehicles and electric cars, chips are used in a growing number of applications, including driver assistance systems, navigation control, Wi-Fi, Bluetooth, video displays and computerized engines. The latest models have between 200 and 400 chips on average.

The shortage of automotive chips comes as leading foundry chipmakers such as Taiwan Semiconductor Manufacturing Co. (TSMC) reduced capacity for automakers after the COVID-19 pandemic slashed car sales. Instead, foundries shipped more chips to companies that produce smartphones, gaming systems and other tech gadgets that remained in high demand.

The situation for automakers has been exacerbated as car sales bounced back sooner than expected in the second half of last year.

Most automotive chipmakers, including Dutch-American firm NXP Semiconductors N.V., Germany’s Infineon Technologies AG and Japan’s Renesas Electronics Corp., are fabless, outsourcing the production of such chips to the likes of TSMC, Samsung Electronics Co. and Taiwan’s United Microelectronics Corp. (UMC).
