For the nine months to December, it suffered a loss of 32.5 billion yen, reversing the net profit of 8.8 billion yen a year earlier.
That was despite a 15.6% rise in sales to 469.9 billion yen, thanks to the effects of a weak yen.
Last week, Honda cut its full-year profit forecast by 3.5% to 545 billion yen as the auto maker grapples with growing recall costs, including from the exploding airbag crisis.
The downgrade came after Honda said it was probing a sixth fatality, in the United States, that may have been caused by a defect in airbags made by Takata.
Takata has been plunged into a public relations crisis at it faces lawsuits, calls for a criminal probe and accusations of "deception and obfuscation" over the deadly defect.
