Mazda has issued a recall affecting roughly 5,700 model year 2014 Mazda3 and 2014-2015 Mazda6 vehicles equipped with a 2.5L engine and a regenerative engine braking system.
When driving the affected vehicles in heavy rain or in deep puddles, the alternator belt may slip causing the Power Control module (PCM) to incorrectly assume failure of the charging system.
Once the PCM assumes that the charging system has failed, the vehicle will stop charging and could result in poor acceleration, loss of steering assist and windshield wiper operation, and a possible engine stall, increasing the risk of a crash.
Mazda will notify owners of the recalled Mazda3 and Mazda6 vehicles, and dealers will reprogram the PCM with updated software. This service will be performed free of charge.
