Honda recalls 437K vehicles with 3.5-liter V6 to fix fuel pump defect

The campaign affects the Honda Accord and the Acura MDX and TLX.

Honda has recalled approximately 437,000 vehicles powered by its 3.5-liter V6 including the 2015-2017 Accord, 2016-2018 Acura MDX, and 2015-2019 TLX.

The company has been monitoring reports of engine stalls for a few years, eventually discovering that sodium deposits from low-quality fuels had caused the fuel pump to fail.

"Re-creation tests confirmed that fuel containing greater than one part per million of sodium could result in restricted vehicle acceleration and/or engine stall," the company wrote in its recall notice.

The Japanese automaker will replace any damaged pumps and install new software in the entire fleet, preventing the fuel pumps from operating in a low-voltage mode that allows the sodium deposits to form.
