## What is wrong

Mazda North American Operations \(Mazda\) is recalling certain 2020 CX\-30 vehicles equipped with all\-wheel drive.  The evaporative vent hose for the fuel tank may be disconnected, possibly allowing fuel to leak from the charcoal canister vent at the rear of the vehicle.


## What can happen

A fuel leak in the presence of an ignition source may increase the risk of a fire.  Additionally, the engine may stall while driving, increasing the risk of a crash.


## The remedy

Mazda will notify owners, and dealers will inspect the evaporative vent hose in the fuel tank.  If the hose is disconnected, it will be reconnected and the charcoal canister with some related parts will be replaced.  Repairs will be performed free of charge.  The recall began July 29, 2020.  Owners may contact Mazda customer service at 1\-800\-222\-5500, Option 4.  Mazda's number for this recall is 4520F.
