The National Highway Traffic Safety Administration (NHTSA) has launched an investigation into more than 1.4 million Honda and Acura vehicles due to concerns over possible engine failure linked to connecting rod bearing issues.
The probe, which began last Friday, covers a range of models equipped with a 3.5-liter V6 engine, including the 2016-2020 Acura MDX, 2018-2020 Acura TLX, 2016-2020 Honda Pilot, 2017-2019 Honda Ridgeline, and 2018-2020 Honda Odyssey.
The NHTSA’s decision to investigate these vehicles comes after receiving 173 complaints from drivers who experienced engine failures. According to the safety agency, these complaints indicate that the connecting rod bearings — which connect the pistons to the crankshaft and convert motion to power the wheels — may be prone to failure, leading to complete engine shutdowns. Among the complaints, one driver reported a crash; however, no injuries were sustained.
This investigation follows a similar issue in 2023, when Honda recalled nearly 250,000 vehicles, including Pilots, Odysseys, and some Ridgeline models, to address the same engine failure risk. At that time, approximately 1,450 warranty claims were recorded, though there were no reports of injuries or fatalities.
The current probe, however, covers a broader set of vehicles that were not included in last year’s recall. The NHTSA’s inquiry aims to assess whether a more extensive recall is needed to address potential defects in these additional models.
Honda has stated that it will fully cooperate with the NHTSA in its investigation. Dealers are already beginning to inspect affected vehicles and repair identified issues as necessary. While Honda has not announced a new recall, the company remains committed to ensuring the safety and reliability of its vehicles.
Drivers concerned about their vehicles can check for existing recalls by visiting the NHTSA’s website, which allows owners to search by Vehicle Identification Number (VIN). Additionally, USA TODAY offers an automotive recall database for easy access to recall information.
