Car Buyer USA - Honda Faces Renewed Scrutiny Over Potential Engine Defects


Honda has long enjoyed a reputation for building dependable, long-lasting vehicles. That reputation is now under pressure as federal safety regulators reopen an investigation into potential engine failures tied to more than 1.4 million Honda and Acura vehicles. The focus is on the popular 3.5-liter V6 engine, and if defects are confirmed, this could turn into one of the most significant recalls in the company’s history.

What’s at Stake

The current investigation stems from connecting rod bearing failures inside the 3.5-liter V6, known internally as the J-series. When these bearings wear prematurely or fail, the results can be catastrophic: loud knocking noises, sudden power loss, stalling, and in some reported cases, fire or crash incidents.

While no injuries have been linked to the defect so far, the potential consequences are serious enough to warrant renewed oversight.

Vehicles Under the Probe

The list of affected models spans some of Honda and Acura’s best-selling vehicles from the late 2010s:

  • Acura TLX (2018–2020)
  • Acura MDX (2016–2020)
  • Honda Pilot (2016–2020)
  • Honda Odyssey (2018–2020)
  • Honda Ridgeline (2017–2019)

All of these vehicles share the same family of engines and could be vulnerable to the same type of failure.

Why the Case Was Reopened

Honda previously issued a recall in late 2023 for around 249,000 vehicles due to a crankshaft manufacturing flaw that could lead to similar failures. Regulators initially believed the matter had been addressed. However, since then, hundreds of new reports have surfaced involving vehicles outside the original recall group. These reports include low-mileage breakdowns, sometimes as early as 22,000 miles, along with a rising number of warranty claims.

With more than 400 fresh complaints filed, and evidence of failures that appear unrelated to the earlier crankshaft issue, regulators determined the case warranted reopening. The new investigation aims to determine whether a second, separate defect exists or whether the problem is broader than originally thought.

What This Means for Owners

For now, the investigation does not guarantee a recall. Regulators will review the engineering details, warranty claims, consumer complaints, and potential manufacturing inconsistencies before deciding whether Honda must take further action. If a recall is ordered, it could be one of the largest in Honda’s history, both in scope and financial cost.

In the meantime, owners of affected models should be proactive:

  • Monitor for unusual engine noises, warning lights, or stalling.
  • Keep service records up to date.
  • Contact a dealer immediately if symptoms appear.
  • Register with Honda’s owner portal to ensure recall notices are received.

Looking Ahead

The investigation is still in its early stages, but the outcome will be critical for Honda. A recall on this scale would carry huge financial implications and could damage the brand’s long-standing reputation for reliability. On the other hand, swift corrective action and transparent communication could reassure customers and preserve trust.

Either way, millions of drivers will be watching closely to see how Honda and regulators handle this issue. The stakes are high—not only for Honda’s reputation, but for the safety and confidence of the families who depend on these vehicles every day.

Owners of these models are encouraged to contact their dealerships promptly for free repairs. For more details, vehicle owners can check the National Highway Traffic Safety Administration (NHTSA) website or consult their automaker’s recall tool to determine if their car is affected and find next steps.
