The U.S. National Highway Traffic Safety Administration (NHTSA) is investigating engine failures in up to 1.4 million Honda and Acura vehicles, including the 2016-2020 Honda Pilot, Acura MDX, 2018-2020 Honda Odyssey, Acura TLX, and 2017-2019 Honda Ridgeline.

The issue involves failing connecting rod bearings in 3.5-liter V6 engines, which can cause complete engine failure.

Honda had recalled 250,000 vehicles in November 2023 for the same issue, but NHTSA received 173 complaints about vehicles not included in the recall, the New York Post has reported.

Honda has confirmed it will cooperate with the investigation.
