The U.S. government’s highway safety agency is investigating complaints that engines can fail on as many as 1.4 million Honda and Acura vehicles.

 

The probe by the National Highway Traffic Safety Administration covers the 2016 through 2020 Honda Pilot and Acura MDX, as well as the 2018 through 2020 Honda Odyssey and Acura TLX. Also included is the 2017 through 2019 Honda Ridgeline.

 

The agency says in documents posted on its website Monday that connecting rod bearings on vehicles with 3.5-liter V6 engines can fail, leading to complete engine failure. Connecting rods link the pistons to the crankshaft and convert vertical motion to move the wheels.
