Investing.com -- The National Highway Traffic Safety Administration (NHTSA) has opened an investigation into more than 1.4 million Honda vehicles sold in the United States due to potential engine failure risks.

The probe, detailed in a letter dated August 20, focuses on connecting rod bearing failures in 3.5-liter V6 engines that could lead to complete engine failure. NHTSA reported receiving 414 complaints about this issue across various Honda and Acura models.

Vehicles under investigation include 2018-2020 model year Acura TLX, 2016-2020 Acura MDX, 2016-2020 Honda Pilot, 2018-2020 Honda Odyssey, and 2017-2019 Honda Ridgeline.

This marks the second major investigation into Honda vehicles in recent years. In 2024, NHTSA launched a similar probe into 1.4 million Honda vehicles following reports of serious engine problems. That investigation came after the Japanese automaker recalled 249,000 vehicles in November 2023.

The current investigation will assess the scope and safety-related risks of the reported engine defects in the affected models.
