U.S. investigates 1.4 million Honda, Acura vehicles for possible engine failure

The National Highway Traffic Safety Administration (NHTSA) is investigating a possible engine failure in up to 1.4 million Honda and Acura vehicles. The connecting rod bearings in these vehicles equipped with 3.5-liter V6 engines may fail, causing the engine to fail completely. The affected models include the 2016 to 2020 Honda Pilot and Acura MDX, the 2018 to 2020 Honda Odyssey and Acura TLX, and the 2017 to 2019 Honda Ridgeline. Honda has recalled approximately 250,000 vehicles in November 2023 to fix this problem.
