What's wrong, in plain English

The impeller inside the low-pressure fuel pump may crack and become deformed, which can cause the fuel pump to fail. If the pump fails while you are driving, the engine may stall, and stalling increases the risk of a crash. Dealers will replace the fuel pump in affected vehicles, free of charge.

2. Contact a Mazda dealer, or call Mazda customer service at 1-800-222-5500 (option 4), to schedule the repair.
