Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Fuel system Vehicle recall #20V347000 · 2020 · 12,097 vehicles
What's wrong: 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.
Why it matters: 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 fix: 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.
Brakes (hydraulic) Vehicle recall #20V346000 · 2020 · 24,037 vehicles
What's wrong: The front brake caliper mounting bolts May not have been tightened properly during assembly, possibly allowing the calipers to loosen.
Why it matters: Loose brake calipers can reduce braking performance or interfere with wheel rotation, affecting vehicle handling. Either of these scenarios can increase the risk of a crash.
The fix: Mazda will notify owners, and dealers will inspect the front brake caliper bolts, tightening them as necessary. If bolts are missing, the affected brake caliper will be replaced. Repairs will be performed free of charge. The recall began July 24, 2020.
Body & structure Vehicle recall #21V086000 · 2021 · 13,857 vehicles
What's wrong: When fully opened, the power liftgate May partially lower unexpectedly when the vehicle is parked facing uphill on a slope.
Why it matters: If the power liftgate unexpectedly lowers while a person is accessing the rear storage area of the vehicle, it can increase their risk of injury.
The fix: Mazda will notify owners, and dealers will update the power liftgate control module software and inspect the serial number of the power liftgate drive unit, replacing it if necessary, free of charge. The recall began April 8, 2021.
