Feds investigate Hyundai, Kia for 1.7M-vehicle engine recall

The investigation will look into whether or not enough vehicles were recalled, and if the recall itself was as timely as it could be.

Just because a recall is underway doesn't mean a company is doing all it can to remedy an issue. That's the belief underlying a federal investigation into and Kia .

The National Highway Traffic Safety Administration is investigating a pair of recalls from Hyundai and Kia, which affected approximately 1.7 million vehicles and was related to engine defects. The investigation is looking into the timeliness of the recalls, and it will determine whether or not the recall covered as many vehicles as it should have.

If the NHTSA investigation finds Hyundai at fault, it could be forced to pony up a big ol' fine.


According to the original recall, which covered just 470,000 examples of the 2011-2012 Sonata sedan, debris leftover from the manufacturing process could affect the vehicles' engines, to the point where they may seize and cause the vehicle to stall.

After that recall, a whistleblower flew to Washington from South Korea to tell federal regulators that Hyundai did not recall as many vehicles as it should have, citing internal documents.

It took until March 31, 2017 for Hyundai to expand its recall to include another 572,000 vehicles, including the 2013-2014 Sonata and Santa Fe Sport. Kia finally issued a recall at that time, as well, covering about 618,000 examples of the 2011-2014 Optima, 2012-2014 Sorento and 2011-2013 Sportage.

It's that move -- taking more than a full year to expand the recall to include those additional vehicles -- that lies at the center of the investigation. Kia knew its vehicles had the same "Theta II" engine as the recalled Hyundai vehicles, so why did it take so long to recall them? The same goes for Hyundai's additional vehicles -- why were they not all recalled at the same time? It's up to the NHTSA to find out now.

"Kia Motors America has, and will continue to, cooperate and collaboratively work with the National Highway Traffic Safety Administration (NHTSA) on all matters related to the Theta engine recall initiative," Kia said in an emailed statement.

"We are fully cooperating with the NHTSA investigation. When it comes to any safety-related issue with Hyundai vehicles, we act quickly and efficiently to address and fix problems for impacted customers, while following all government regulations and requirements," Hyundai said in an emailed statement. "We have an open, cooperative and transparent relationship with NHTSA and will continue to work closely with them on the Theta II engine recall."
