Hyundai and Kia are recalling about 3.4 million vehicles in the US and urged owners not to park the vehicles outside due to the risk of engine compartment fires.
According to Reuters, Hyundai said the automaker received as many as 21 reports of fires and 21 other thermal incidents since 2017 while Kia had at least 10 confirmed cases fire and melting incidents.
The recalls include several car and SUV models from 2010 through 2019, including Hyundai's Santa Fe SUV and Kia's Sorrento SUV.
The anti-lock brake control module can leak fluid and cause an electrical short, which can touch off a fire while the vehicles are parked or being driven, according to the documents posted Wednesday by the US safety regulators.
Affected Kia models include the 2010 through 2019 Borrego, the 2014 to 2016 Cadenza, 2010 through 2013 Forte, Forte Koup and Sportage, the 2015 to 2018 K900, the 2011 to 2015 Optima, the 2011 to 2013 Optima Hybrid and Soul, the 2012 to 2017 Rio, the 2011 to 2014 Sorento, and the 2010 to 2011 Rondo.
Hyundai models that are being recalled include the 2011 to 2015 Elantra, Genesis Coupe, and Sonata Hybrid, the 2012 to 2015 Accent, Azera, and Veloster, the 2013 to 2015 Elantra Coupe and Santa Fe, the 2014 to 2015 Equus, the 2010 to 2012 Veracruz, the 2010 to 2013 Tucson, the 2015 Tucson Fuel Cell, and the 2013 Santa Fe Sport.
