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.
The powertrain control module (PCM) may incorrectly assume that the charging system has failed, in the event that water causes slippage of the alternator belt. This can cause needed vehicle accessories and functions such as power steering or windshield wiper operation to fail. Dealers will reprogram the PCM with updated software free of charge to resolve the concern.
Mazda notified owners of affected vehicles starting in May 2014. You can check with your dealer to see if your vehicle is involved in this program. It is helpful to have your VIN (Vehicle Identification Number) on hand when you contact them. The Mazda recall number is 7314D.
