The National Highway Traffic Safety Administration (NHTSA) announced on Wednesday the closure of an investigation into fire risks in 3 million Hyundai and Kia vehicles. This decision follows eight recalls initiated by the Korean automakers to address engine fires. The investigation began in 2019 and was intensified in 2021 after reports of 161 fires resulting from engine failures.
According to the NHTSA, the majority of the recalled vehicles experienced lower fire rates post-recall fixes, while those remaining unresolved showed relatively high fire rates. Hyundai and its affiliate Kia have not provided immediate comments on the matter.
In response to the investigation, both companies committed to sending reminders to affected owners every eight months for the next three years, aiming to boost recall completion rates and reduce future engine fires. The NHTSA emphasized that the automakers have incorporated engine control software modifications, including the Knock Sensor Detection Software, designed to detect potential engine failure, alert drivers, and limit engine power. Additionally, extended limited engine warranties have been offered by both Hyundai and Kia.
Kia, separately, recalled 80,000 2011 model year Sorento vehicles in December for inspections and potential engine replacements due to fire risks. Furthermore, in November, the NHTSA initiated a separate probe into 16 recalls covering 6.4 million Hyundai and Kia vehicles related to brake fluid leaks that could lead to fires. These recalls are linked to issues with anti-lock braking systems (ABS) and hydraulic electronic control units (HECU) manufactured by the same parts supplier, prompting a series of recalls since 2016.
