Mazda3, Mazda6 and CX-5 engines can stall unexpectedly

NHTSA campaign 19V497000 · Reported 2019-06-27 · Mazda North American Operations

high How serious is it? About this label

Serious — an unexpected stall can happen with no warning and increases the crash risk, though the notice does not tell owners to stop driving.

What's wrong, in plain English

The computer that controls the engine has a software bug. Because of it, the engine can stall without warning. Losing engine power in traffic or at speed is dangerous. The repair is simple: a dealer reloads corrected software into that computer, free of charge, and no parts are replaced. The recall began August 20, 2019, so check your VIN even if you bought the car used and never received a letter from Mazda.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see whether this repair was ever done on your car.
2. Call your Mazda dealer or Mazda customer service at 1-800-222-5500, option 4 (recall 3719F), to schedule the software reprogramming.
3. Have the software updated — the repair is free.
