NHTSA Launches Preliminary Investigation into Over 1.4 Million Honda and Acura Vehicles
The National Highway Traffic Safety Administration (NHTSA) has initiated a preliminary evaluation into more than 1.4 million Honda and Acura vehicles following numerous reports of engine failure. This probe includes models equipped with Honda’s 3.5-liter V-6 engine and spans several popular lines:
- Honda: 2016–2020 Pilot, 2017–2019 Ridgeline, 2018–2020 Odyssey
- Acura: 2016–2020 MDX, 2018–2020 TLX
What's Different This Time?
This new investigation is separate from a 2023 recall linked to connecting-rod bearing failures—a condition stemming from a crankshaft manufacturing defect. Despite overlapping model years, NHTSA confirmed that the current engine failure complaints are distinct from that earlier recall.
What Has Triggered This Investigation?
To date, the Office of Defects Investigation (ODI) has received:
- 414 incident reports, including four involving crashes or fires
- An additional 2,598 reports from the manufacturer
While none of the reported incidents have resulted in injuries or fatalities, the volume and pattern of failure prompted NHTSA to open the new probe.
What Does This Mean for Vehicle Owners?
This preliminary stage doesn’t confirm a recall yet. However, if NHTSA deems the issue widespread or safety-critical enough, a formal recall could follow. Until then:
- Owners of the affected models are encouraged to monitor the NHTSA recalls website for updates
- Stay alert to any vehicle symptoms—such as unusual noises, warning lights, or poor performance—and report them promptly
Why This Matters
For drivers and owners of the listed Honda and Acura models, this investigation underscores the importance of being proactive about vehicle health. Engine issues—even if seeming minor at first—can escalate and pose a safety risk.
Bottom line: No confirmed recall yet, but vigilance is essential. Keep tabs on future updates and take action if you notice unusual behavior in your vehicle.
