(New York) Honda’s North American arm is recalling more than 2.5 million vehicles in the United States and about 300,000 in Canada over a fuel pump defect that could increase risks engine failure or stalling while driving.

According to documents released by the National Highway Traffic Safety Administration (NHTSA), the fuel pump impeller used for 2017 to 2020 Acura and Honda vehicles was improperly cast. This causes the impellers “may warp and interfere with the fuel pump” over time, regulators said, rendering the fuel pump inoperable.

Honda said approximately 297,837 Canadian vehicles are affected by the recall, but no crashes or injuries related to the issue have been reported.

If the fuel pump module is not working, the car’s engine may not start or stall while driving, NHTSA said, increasing the risk of a crash and injury. Honda says it has not received any reports of accidents or injuries related to this recall to date.

The automaker announced Thursday that it will replace the fuel pumps in all vehicles affected by the recall free of charge, in separate phases. The first batch of landlord notification letters will be sent to Canada and the United States in February.

Notification to dealers was expected to begin earlier this week, according to NHTSA documents.

Earlier this week, NHTSA and Honda also announced the recall of more than 106,000 2020-2022 CR-V hybrid vehicles due to a missing fuse in the 12-volt battery exterior cable power circuit. This can cause the battery cable to short circuit or overheat in a crash, regulators said.
