2020 CX-30 – Fuel May Leak from Rear of Vehicle – Safety and Emission Recall 4520F
NHTSA Campaign Number 20V-347
July 2020
This notice applies to your vehicle: VIN ________
Dear Mazda Owner:
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act. Mazda Motor Corporation has decided that a defect which relates to motor vehicle safety exists in certain 2020 model year CX-30 vehicles equipped with all-wheel drive and produced from November 13, 2019 through March 24, 2020. If you received this notice, your vehicle is included in this Recall.
What is the problem?
On certain subject vehicles equipped with all-wheel drive, when fully refueling the vehicle, liquid fuel will eventually fill the charcoal canister resulting in a leak. A leak from the canister 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. A Malfunction Indicator Lamp (MIL) and warning messages may be displayed in the Multi-Information Display and Active Driving Display to indicate a malfunction in the vehicle emissions system if this defect occurs. The defect can occur if the fuel evaporative vent hose is not connected to the fuel sender unit due to an improper manufacturing process at the fuel tank manufacturing plant.
What will Mazda do?
Protect What Is Important To You
Your Mazda dealer will inspect the fuel evaporative vent hose in the vehicle fuel tank. If the hose is found to be disconnected, the dealer will connect the hose to the fuel sender unit and replace the charcoal canister and some related parts with new ones. The inspection and repair will be performed at no cost to you.
How long will it take?
It will take approximately one hour to complete the inspection. If the vent hose is disconnected, it will take approximately one and a half hours to complete the repair; however, your Mazda dealer may need your vehicle for a longer period of time.
Mazda will provide alternate transportation, if needed, when your vehicle is at an authorized Mazda dealership for a recall repair. Schedule an appointment with an authorized Mazda dealer so they can discuss and accommodate your needs.
What should you do?
Mazda is concerned about your safety, and we encourage you to contact any authorized Mazda dealer to schedule an appointment to have your Mazda vehicle inspected as soon as possible. You do not need to bring this notice to the dealer, but it may assist in the check-in process.
Emission Law Information: To ensure your full protection under the emission warranty made applicable to your vehicle by State or Federal Law, you should have this recall completed as soon as possible. Failure to do so could be determined as lack of proper maintenance of your vehicle. Also, your vehicle may fail a state or local emission inspection if this recall is not completed.
Important notice to owners registering vehicles in California and Massachusetts: California Department of Motor Vehicles and the Commonwealth of Massachusetts, in conjunction with the California Air Resources Board and the Environmental Protection Agency for the State of Massachusetts, have implemented the Registration Renewal/Recall Tie-In Program, which requires the completion of Emission Recalls prior to registration renewal. Mazda dealers will provide a Vehicle Emission Recall – Proof of Correction Certificate upon completion of the recall. Be sure to keep the proof of correction certificate provided by the Mazda Dealer until needed for the registration renewal process.

Attention: Mazda General, Parts and Service Managers
Subject: Notification of two Safety Recalls 4420F and 4520F 2020 CX-30 and Mazda3
Dear Mazda Dealer Partners,
Mazda Motor Corporation has decided to conduct two Recall Campaigns impacting the 2020 Mazda3 and CX30 built at MMVO. Please see the descriptions, models and VIN Ranges below for both recalls.
Safety Recall 4420F: 2020 CX-30 and 2020 Mazda3 Front Brake Caliper Bolts May loosen
Affects 23,960 US vehicles
| Models | Subject VIN range | Subject production date range |
| CX-30 built at MMVO Mazda3 built at MMVO | 3MVDM LM 100339- 132854
3MZBP LM 124464- 138941 | From October 22, 2019 through March 6, 2020 |
STOP DELIVERY: There are currently 6,702 vehicles in dealer inventory under Recall 4420F.
These vehicles cannot be delivered to customers until the vehicle is repaired.
Concern Outline:
On certain subject vehicles, it is possible that the front brake caliper mounting bolts may loosen and fall off, as the front brake caliper mounting bolts may not have been tightened to the proper torque specification. Loose or missing brake caliper mounting bolts may cause reduced braking performance and caliper interference with wheel rotation, resulting in loss of vehicle control and increasing the risk of a crash.
For all subject vehicles:
The brake caliper bolt tightening torque will be checked. If the torque is not adequate, the front caliper mounting bolts will be tightened to the proper specification. If in the rare occurrence where bolts are missing, the affected front brake caliper will be replaced using new parts.
Safety and Emissions Recall 4520F: 2020 CX-30 AWD Fuel Leak from Rear of Vehicle
Affects 12,096 US vehicles
| Model | Subject VIN range | Subject production date range |
| CX-30 AWD built at MMVO | 3MVDM LM 104188- 137005 | November 1 3, 2019 through March 24, 2020 |
STOP DELIVERY: There are currently 5,059 vehicles in dealer inventory under Recall 4520F. These vehicles cannot be delivered to customers until the vehicle is repaired.
Concern Outline:
On certain subject vehicles, the fuel evaporative vent hose may not be connected to the fuel sender unit. If the vent hose is disconnected, when fully refueling the vehicle, liquid fuel will eventually fill the charcoal canister, resulting in a leak, which may increase the risk of a fire in the presence of an ignition source. Additionally, the engine may stall while driving, increasing the risk of a crash.
For all subject vehicles:
The fuel evaporative vent hose in the vehicle fuel tank will be inspected. If the hose is found to be disconnected, the hose will be connected to the fuel sender unit. On sold vehicles, the charcoal subcanister will be replaced.
Owner Notification:
Mazda will notify owners of affected vehicles for both recalls no later than August 7, 2020.
Vehicles will display in eMDCS as “Not Launched” on June 1 5, 2020 but can be repaired as outlined above.
Important Safety Notice:
The National Traffic and Motor Vehicle Safety Act prohibits the delivery of any subject vehicle without performing the necessary repair for defects or failures. Failure to perform applicable recalls before delivery can result in extensive dealer fines and penalties from the Federal Government. Therefore, you must complete this recall for all affected vehicles in your inventory prior to delivery.
To help you effectively perform these recalls, Mazda has developed the following resources:
- Parts and Warranty Information and Repair procedures will be posted on MGSS by June 1 5, 2020.
- For Warranty questions, contact the Warranty Hotline at (877) 727-6626, Option 3.
- Vehicles will display in eMDCS as “Not Launched” on June 1 5, 2020.
- For parts questions, contact the Dealer Assistance Group at (877) 727-6626 Option 2.
- For Recall questions please fill out the Dealer Recall Help Form located on MX-Connect under the Warranty Tab.
Please make certain the appropriate personnel in your dealership are aware of these resources and are familiar with the details of these recalls before responding to customer inquiries. We apologize for any inconvenience these recalls may cause you and your customers. Your understanding and support in carrying out these campaigns are greatly appreciated.

Subject: RE: Safety Recalls 4420F and 4520F – Parts and Repair Updates
This message is to clear up any confusion regarding the notification of these two recalls and the repairs that may be required.
Safety Recall 4420F: 2020 CX-30 and 2020 Mazda3 Front Brake Caliper Bolts May loosen
It is expected that over 99.9% of the vehicle population will only require the front brake caliper bolts to be tightened. Therefore, if a technician finds a vehicle in which the front caliper bolt is missing they will need to contact Dealer Recall Help to receive authorization to replace the affected front brake caliper assembly. A photo will be required for documentation of that VIN. The Dealer Recall Help team will contact the DAG to order the part for you.
Safety and Emissions Recall 4520F: 2020 CX-30 AWD Fuel Leak from Rear of Vehicle
It is expected that over 99.8% of the vehicle population will only require an inspection of the fuel evaporative hose connection.
If the fuel evaporative hose is found to be disconnected, there are two procedures depending on whether the vehicle has been retailed or is still in dealer inventory.
Retailed Vehicles: If a technician finds a vehicle with the fuel evaporative vent hose disconnected, they will need to contact Dealer Recall Help to receive authorization to replace the charcoal sub-canister and some related parts. A photo will be required for documentation of that VIN.
Non-Retailed Vehicles (Dealer Inventory): If the vehicle has not been fully filled with fuel, there is no contamination of the charcoal sub-canister. Therefore, if a technician finds a disconnected fuel evaporative hose, just reconnect the hose to close the recall. The Dealer Recall Help team does not need to be contacted. Final copies of the parts and warranty information and repair procedures will be posted to MGSS as quickly as possible. They should be completed by June 1 7th at the latest.
If there is a need to order any other parts for this recall, please fill out the Dealer Recall Help Form located on MX-Connect under the Warranty Tab. The DAG will only process orders previously approved by Dealer Recall Help.
As a reminder for these two recalls vehicles in dealer stock in Not Launched status can be inspected or repaired and the warranty claim should be submitted as soon as possible to close the recall. If you have a customer demanding the recall repair you can inspect or repair those vehicles as well.
For additional questions, please don’t hesitate to submit a Dealer Recall Help request.
Please make sure the appropriate staff at your dealership are aware of these orders.

Effective Immediately:
We have updated the Parts and Warranty Information and Repair Procedure for this recall regarding failed inspection results. Any vehicle that has a disconnected hose, must have a photo of the disconnected hose with the RO in the background for verification of the VIN and the repair order documenting the disconnection is required to be attached to the Warranty Claim. Updated Parts and Warranty Information has been posted to eMDCS and MGSS. Updated Repair Procedures have been placed on MGSS. Any claim submitted for a disconnected hose will pend for review of attachments.
Please make certain all service staff in your dealership are aware of these changes and contact Dealer Recall Help or Warranty Hotline if you have any questions regarding the document changes.
Protect What is Important to You
Sincerely,

Attention: Mazda General, Parts and Service Managers
Subject: July 29 – Launch of two Safety Recalls 4420F and 4520F 2020 CX-30 and Mazda3
Dear Mazda Dealer Partners,
Mazda Motor Corporation has decided to conduct two Recall Campaigns impacting the 2020 Mazda3 and CX-30 built at MMVO. Please see the descriptions, models and VIN Ranges below for both recalls.
Both recalls will display Open status on July 29, 2020
Safety Recall 4420F: 2020 CX-30 and 2020 Mazda3 Front Brake Caliper Bolts May Loosen and Fall Off
Affects 23,960 US and US Territory vehicles
| Models | Subject VIN range | Subject production date range |
| CX-30 built at MMVO
Mazda3 built at MMVO | 3MV DM**** LM 100339-132853
3MZ BP**** LM 124500- 138941 | From October 22, 2019 through March 6, 2020 |
STOP DELIVERY: There are currently 1 ,053 vehicles in dealer inventory under Recall 4420F.
These vehicles cannot be delivered to customers until the vehicle is repaired.
Concern Outline:
On certain subject vehicles, the front brake caliper mounting bolts may loosen and fall off. Loose or missing brake caliper mounting bolts may cause reduced braking performance and/or caliper interference with wheel rotation, resulting in loss of vehicle control and increasing the risk of a crash. Drivers may hear abnormal grinding or rattling noises due to the brake caliper contacting the wheel and possibly other vehicle components. This defect is due to a manufacturing assembly process error whereby certain front brake caliper mounting bolts may not have been tightened to the proper torque specification.
For all subject vehicles:
The brake caliper bolt tightening torque will be checked. If the torque is not adequate, the front caliper mounting bolts will be tightened to the proper specification. In the rare occurrence where bolts are missing, the affected front brake caliper will be replaced using new parts.
Safety and Emissions Recall 4520F: 2020 CX-30 AWD Fuel May Leak from Rear of Vehicle
Affects 12,097 US vehicles
| Model | Subject VIN range | Subject production date range |
| CX-30 AWD built at MMVO | 3MVDM LM | November 1 3, 2019 through March 24, 2020 |
STOP DELIVERY: There are currently 930 vehicles in dealer inventory under Recall 4520F.
These vehicles cannot be delivered to customers until the vehicle is repaired and please do so as soon as possible.
Concern Outline:
On certain subject vehicles, the fuel evaporative vent hose may not be connected to the fuel sender unit. If the vent hose is disconnected, when fully refueling the vehicle, liquid fuel will eventually fill the charcoal canister, resulting in a leak, which may increase the risk of a fire in the presence of an ignition source. Additionally, the engine may stall while driving, increasing the risk of a crash.
For all subject vehicles:
The fuel evaporative vent hose in the vehicle fuel tank will be inspected. If the hose is found to be disconnected, the hose will be connected to the fuel sender unit, and on sold vehicles, the charcoal canister and related parts will be replaced.
Owner Notification:
Mazda will notify owners of affected vehicles for this recall on July 29, 2020 and all unrepaired vehicles will be in Open status in eMDCS. Effective July 29, 2020 this recall will be tracked on the Missed Recall report.
Important Safety Notice:
The National Traffic and Motor Vehicle Safety Act prohibits the delivery of any subject vehicle without performing the necessary repair for defects or failures. Failure to perform applicable recalls before delivery can result in extensive dealer fines and penalties from the Federal Government. Therefore, you must complete this recall for all affected vehicles in your inventory prior to delivery.
To help you effectively perform these recalls, Mazda has developed the following resources:
1. Parts and Warranty Information and Repair procedures are posted on MGSS and Parts and Warranty Information is available on eMDCS.
2. For Warranty questions, contact the Warranty Hotline at (877) 727-6626, Option 3.
3 . For parts questions, contact the Dealer Assistance Group at (877) 727-6626, Option 2.
4. For Recall questions please fill out the Dealer Recall Help Form located on MX-Connect under the Warranty Tab.
Please make certain the appropriate personnel in your dealership are aware of these resources and are familiar with the details of these recalls before responding to customer inquiries. We apologize for any inconvenience these recalls may cause you and your customers. Your understanding and support in carrying out these campaigns are greatly appreciated.
