Recall 14V173000

Charging System May Fail

Recall Details

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.

Our Quick Take

If the alternator belt should slip due to getting excessively wet, such as when driving in heavy rain or through deep puddles, the powertrain control module may incorrectly assume failure of the charging system. This can cause the loss of operation of vehicle accessories necessary for safe driving, such as windshield wipers and power steering assist.

What Should You Do?

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.

Summary
Mazda North America Operations (Mazda) is recalling certain model year 2014 Mazda3 vehicles manufactured June 12, 2013, through December 18, 2013, and model year 2014-2015 Mazda6 vehicles manufactured May 20, 2013, through December 4, 2013, and both 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.
Consequence
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, and dealers will reprogram the PCM with updated software, free of charge. The recall began on May 19, 2014. Owners may contact Mazda at 1-800-222-5500. Mazda's number for this recall is 7314D.
