U.S. investigates engine failure risk in 1.4 million Honda and Acura vehicles

U.S. safety regulators are investigating potential engine failures in approximately 1.4 million Honda and Acura vehicles, raising concerns for owners about potential breakdowns and safety issues. The National Highway Traffic Safety Administration (NHTSA) launched the inquiry following reports that engines on certain models may fail due to faulty connecting rod bearings, a critical component linking pistons to the crankshaft. If these bearings fail, drivers could experience sudden engine shutdowns, posing risks on the road.

The investigation targets 2016-2020 Honda Pilot and Acura MDX models, 2018-2020 Honda Odyssey and Acura TLX models, and 2017-2019 Honda Ridgeline models equipped with 3.5-liter V6 engines. NHTSA’s findings could prompt a significant recall if widespread risks are confirmed. In 2023, Honda recalled 250,000 vehicles over similar concerns, yet hundreds of complaints indicate the issue persists in models not included in the previous recall.

An owner in one NHTSA complaint described a near-crash incident due to a sudden engine failure, a problem echoed by 173 others who have filed complaints, underscoring the urgent need for action. “Our top priority is understanding the extent of this issue and ensuring customer safety,” NHTSA noted in a statement, adding that it will examine Honda’s handling of the initial recall.

Honda has pledged full cooperation with the agency’s probe, stating that it aims to prioritize safety and transparency in addressing the situation. The inquiry will determine whether additional recalls are necessary to safeguard Honda and Acura owners, and NHTSA is expected to release further updates on the investigation.
