Launch of Owner Notification Program ONP09 – 2023MY Mazda CX-50 Wind Noise from
Roof Rack Crossbars
Dear Mazda Dealer Partners,
Mazda Motor Corporation has decided to conduct an Owner Notification Program on certain 2023MY
CX-50 vehicles built at the Mazda Toyota Manufacturing Alabama (MTM) plant and sold in the United States
equipped with the Mazda original accessory Roof Rail Crossbar part # VA40V3840 and VA40S3840. Please
see the description, model, year, and VIN ranges below.

Subject Vehicles:

Subject production date range

2023 CX-50

Varies – but all are 2023MY CX-50
vehicles

Varies but all vehicles are 2023 CX-50
built at the MTM Plant

Concern Outline: To reduce wind noise, an Aero-Infill kit containing rubber strips are inserted into the CX50 roof-rack crossbars, making for a quieter driving experience. The rubber strips do not need to be removed
once installed.
Owner Notification: Mazda will begin shipping an Aero-Infill kit to 5,283 Registered Owners via UPS
overnight delivery on March 14, 2024. It will take approximately 10 days to ship all the kits. When
received, owners can self-install this kit and are not required to visit a dealer. Instructions to install the
Aero-Infill Kit are included in the parts kit they received. If you have a vehicle from Mazda Canada Inc. in
your dealership, please advise the customer to contact Mazda Canada Inc. regarding repairs to a Mazda
Canada VIN.
Mazda Dealer Action Requested:
• Please continue to review all parts sales from your dealership for the Mazda Genuine Accessory
part number(s) VA40V3840 (Dealer installed Mazda Genuine Roof Rack Crossbars) and match the
customer with a VIN, then follow the steps below “For All Subject Vehicles”.

For All Subject Vehicles: There are 3 repair options for all customers in the ONP09 campaign.
• Customer Self-Install: In most cases the customer will have the Aero-Infill parts kit to repair the vehicle
on their own (sent by Mazda in a UPS Box with instructions and a parts kit).
• Dealer Installation, vehicle in campaign ONP09: If the customer requests the Aero-Infill parts kit to be
installed by a dealer, please advise them to bring the parts kit they received to the appointment.
NOTE: If a customer has misplaced their parts kit, please order a kit from the DAG and install for the
customer at the dealer. Do not give the customer the kit you ordered from the DAG, you must install the
parts kit for the customer in this case and enter a warranty claim for ONP09.
• Dealer Installation or Accessory sold to Owner with VIN, vehicle not in Campaign ONP09: If a
customer vehicle is not in campaign ONP09, but they have the original genuine Mazda Accessory part
VA40V3840 contact Dealer Recall Help with the VIN so it can be manually added to the campaign, then
order parts from the Dealer Assistance Group (DAG).
Parts Ordering – Mazda dealers:
The parts kit is not an item you need to stock at your dealer. Please do not order a parts kit unless required
based on the section “For All Subject Vehicles”. If needed, a parts kit can be ordered by contacting the
Dealer Assistance Group (DAG) using the DAG Email portal.
To help you effectively perform this Owner Notification Program, Mazda has developed the following
resources:
1. Parts and Warranty Information and Repair Procedures are posted on MGSS.
2. For Warranty questions, please contact the Warranty Hotline at [email protected]
3. For all parts questions, contact the Corporate Dealer Assistance Group at (877) 727-6626 Option

Please make certain the appropriate personnel in your dealership are aware of these resources and are
familiar with the details of this recall before responding to customer inquiries. We apologize for any
inconvenience this Owner Notification Program may cause you and your customers. Your understanding
and support in carrying out this campaign are greatly appreciated.
Sincerely,

2023 Mazda CX-50 Wind Noise From Roof Rack Crossbars - Owner Notification Program (ONP) 09
Dear Valued Mazda CX-50 Owner:
First, we’d like to thank you for being a part of the Mazda family and choosing the 2023 Mazda CX-50.
We truly appreciate your business and hope you are enjoying your vehicle. At Mazda, we pride
ourselves on providing you with the best driving experience possible. To this end, we would like to
provide an upgrade to your vehicle, enhancing your driving experience even more.
Enclosed is a kit with six rubber strips that fits in your roof crossbars. By installing the rubber strips into
your crossbars, wind noise will be further reduced, making for a quieter driving experience. The rubber
strips do not need to be removed once installed.
To install the rubber strips, you have two options:
• Self-installation: You will install 3 rubber strips for each cross bar using the instructions inside
the kit bag. Please see the self-installation tips below using the paper instructions in the kit.
• Bring your parts kit to a Mazda dealer for installation: To use this option, schedule an
appointment with your dealer to have the kit you received installed by a Certified Mazda
Technician at no cost to you. You can make an appointment by going to your preferred Mazda
Dealers website, logging onto www.mazdausa.com/Owners or in the MyMazda App.
Self-installation tips:
• Detailed installation instructions are printed inside the kit. You will need to cut-to-fit only 1
rubber strip for each cross bar as the other 2 strips drop-in easily.
• Installation requires no special tools - just a pen and a pair of household scissors.
• We recommend removing the crossbars from the vehicle and placing them on a table or other
flat work surface. This is to prevent injury during installation.
• Please use caution when using any sharp object such as scissors to avoid injury.
• If you need help installing the rubber strips, please contact the Service Department at any Mazda
dealer.
The campaign number is listed above for reference. Again, please be sure to bring the kit with you if you
decide to visit the dealership.
Still have questions? If you have any questions regarding this program, please contact our Customer
Experience Center at (800) 222-5500, option #6.
We encourage you to install these rubber strips to enhance your driving experience. Your satisfaction is a
priority for Mazda. We actively work to improve our products and search for solutions to improve your
ownership experience.
Sincerely,
Mazda North American Operations
