Structure

Transport Canada recall 2021075 · manufacturer campaign 4621B

19 February 2021

Transport Canada lists: CX 30 2020–2021

What is wrong

On certain vehicles, the power liftgate may partially lower from the fully open position when the vehicle is parked facing uphill on a slope. The liftgate will not lower all the way to the closed position.

Why it matters

A liftgate that partially lowers suddenly could create a risk of injury.

What the dealer will do

Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to update the power liftgate software. The dealer will also inspect the liftgate drive units and replace them, if necessary.

Fuel System

Transport Canada recall 2020265 · manufacturer campaign 4520F

12 June 2020

Transport Canada lists: CX 30 2020

What is wrong

On certain vehicles equipped with all-wheel drive, a hose that connects the evaporative emissions (EVAP) system to the fuel tank may not have been installed correctly. This could cause fuel to flow directly into the EVAP system when the fuel tank is filled completely. As a result, fuel may leak through the charcoal canister vent. A charcoal canister that is filled with fuel could also cause the engine to stall. Note: This problem could cause the malfunction indicator light (MIL) to turn on in the instrument cluster and/or the active driving display.

Why it matters

A fuel leak can create the risk of a fire. An engine that stalls while driving could increase the risk of a crash.

What the dealer will do

Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to inspect the EVAP hose connection inside the fuel tank and reconnect it, if necessary. If the hose is found disconnected, the charcoal canister will also be replaced. You should avoid completely filling the fuel tank until the recall repairs are completed.

Brakes

Transport Canada recall 2020264 · manufacturer campaign 4420F

12 June 2020

Transport Canada lists: CX 30 2020 · Mazda 3 2020

What is wrong

On certain vehicles, the front brake caliper mounting bolts may not be properly tightened. This could cause the bolts to loosen, which may result in reduced brake effectiveness. If the bolts fall out, the caliper could also come in contact with the wheel rim and cause a loss of vehicle control.

Why it matters

Reduced brake effectiveness could cause an increase in stopping distance and create the risk of a crash. A loss of vehicle control could increase the risk of a crash.

What the dealer will do

Mazda will notify owners by mail and instruct you to take your vehicle to a dealer to check the tightening torque of the front brake caliper mounting bolts. If a bolt is missing, the caliper and remaining bolt will be replaced.
