Mazda CX-30 all-wheel drive may leak fuel

NHTSA campaign 20V347000 · Reported 2020-06-12 · Mazda North American Operations

high How serious is it? About this label

Serious — a fuel leak can cause a fire and the engine may stall while driving, raising crash risk; the notice does not say to stop driving, but get it fixed promptly.

What's wrong, in plain English

Some 2020 CX-30 vehicles with all-wheel drive have a vent hose on the fuel tank that may be disconnected. When that hose comes loose, fuel can leak out of the vent at the back of the vehicle. Leaking fuel near anything hot or sparking can start a fire, and the engine can also stall while you are driving. Mazda dealers will check the hose, reconnect it if needed, and replace the charcoal canister and some related parts free of charge.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your CX-30 is affected.
2. Contact your Mazda dealer or Mazda customer service at 1-800-222-5500, Option 4 (recall 4520F).
3. Have the vent hose inspected and repaired — all work is free.
