Mazda North America Operations is recalling 5,700 2014 model-year Mazda3 and 2014-2015 model-year Mazda6 vehicles so dealers can update the power control module software, the National Highway Traffic Safety Administration reports.
The recall, expected to get under way later this month, will cover Mazda3 cars manufactured from June 12, 2013, through Dec. 18, 2013, and Mazda6 cars manufactured from May 20, 2013, through Dec. 4, 2013. They are all equipped with a 2.5L engine and a regenerative engine braking system.
When these vehicles are driven in heavy rain or through deep puddles, the alternator belt may slip and cause the power control module (PCM) to incorrectly assume failure of the charging system. As a result, the vehicle might stop charging. This could lead to poor acceleration, loss of steering assist and windshield wiper operation, or even a possible engine stall.
Mazda dealers will reprogram the PCM with updated software, free of charge. The recall is expected to begin this month. Vehicle owners can reach Mazda at 1-800-222-5500. Mazda's number for this recall is 7314D.
