The National Highway Traffic Safety Administration (NHTSA) has closed an investigation into potential risk of engine fires in Hyundai and Kia vehicles, determining no further action will be needed, Reuters reports.
The agency first launched its investigation of the problem in 2019, with the effort escalating in 2021 after receiving reports of 161 fires caused by engine failures. This investigation is separate from the probe NHTSA opened in November, related to oil leaks in 6.4 million Kia and Hyundai vehicles posing fire risks.
Kia and Hyundai have issued a total of eight recalls for engine fire risks. During its investigation, NHTSA found that those who received the recall fixes experienced fewer incidents related to engine fires than those who failed to receive the repairs.
The automakers said that they have extended their limited engine warranties and are utilizing an engine control software modification that will detect potential engine failure, limit engine power, and warn the driver.
Hyundai will be reminding drivers affected by the recalls to receive repairs for the next three years. Kia will send reminders out every eight months for the next three years as well.
