The Hyundai Group is recalling 1.5 million Hyundai and Kia models from model years 2011-2014 to address a problem with engine detritus that could lead to failure and potential crashes.
The recall affects 2013-14 Hyundai Santa Fe and Sonata, and Kia Optima (2011-14), Sorento (2012-14) and Sportage (2011-13). Canadian vehicles account for 114,187 of the units being recalled, with 1.19 million in the US and the remaining 171,348 in South Korea.
The affected engines are the 2.0-litre and 2.4-litre 4-cylinders that are part of the Theta family. Hyundai discovered debris in them left behind by the manufacturing process. The debris could clog up oil flow, causing the engine to stall or, at worse, seize up.
In either case, there would be an immediate loss of power, which could be catastrophic if it happens while the car is being driven because the sudden loss in power and speed could result in a crash.
Although Hyundai and Kia are unaware of any injuries resulting from the incident, owners are urged to immediately attend a dealership if they hear a loud knock from the engine compartment, or if the engine light comes on.
Otherwise, owners will receive recall notices in May, with action starting May 22 to replace the entire engine block.
