Hyundai Motor Co. and Kia Motors Corp. on Friday said they plan to recall 114,187 Canadian vehicles due to possible engine defects.
The recall is part of a larger effort that covers 1.5 million affected models in the United States and South Korea that could cost the two firms hundreds of millions of dollars each.
Canadian models impacted by the recall are the 2013-14 model year Hyundai Sonata sedans and Santa Fe Sport crossovers, as well as 2011-13 Kia Optima and Sportage crossovers and 2012-14 Kia Sorento crossovers.
According to Transport Canada, certain models equipped with 2.0-litre and 2.4-litre engines could contain metallic debris, which in turn could cause the engine to stall while in motion, increasing the risk of a crash. Dealers will inspect and replace the affected parts as necessary.
The two automakers submitted plans to recall 1.3 million vehicles in the U.S. and 171,348 vehicles in South Korea due to similar problems.
The global recall effort revives quality concerns at a time when Hyundai and Kia face a sharp drop in China sales and sluggish demand in Canada, the United States and South Korea.
The recall could hit earnings by costing each company as much as $295.3 million (250 billion won), said Koh Tae-bong, an analyst at Hi Investment & Securities.
The companies declined to comment on the cost of the recall.
It is not the first time Hyundai and Kia have been forced to recall vehicles because of defects in the Theta engines, which they manufacture themselves.
In 2015, Hyundai Motor recalled 470,000 Sonata sedans in the United States to replace faulty engine parts.
A Hyundai spokeswoman said the latest recall involves a different engine problem. But a South Korean ministry official said they were similar.
The ministry said metal debris in crankshafts could cause engine damage, leading to possible engine stalling.
"The recall is related to a manufacturing process problem, not the structural problem of Theta 2GDi engines and we have completed improvements through appropriate measures," the companies said in a statement.
The recall in South Korea covers Hyundai's Sonata, Grandeur sedans and Kia's K5, K7 and Sportage models equipped with a 2.0-litre or 2.4-litre Theta 2 gasoline engine produced before August 2013, the South Korean transport ministry said.
Hyundai will replace a defective engine with a new one after inspection. The recall in South Korea will start on May 22.
