Announcement of Safety Recall 6524A-2024MY CX-90-Sudden Increase in Steering Effort
Mazda
Motor Corporation has decided to conduct a Safety Recall on certain 2024MY CX-90 vehicles. Please see the description, model, year, and VIN range below for the vehicles in this campaign. There are 43,695 vehicles affected with this concern in the US.
Concern Outline: While driving, the customer may feel a sudden increase of effort when steering the vehicle. Sudden and unexpected change of steering effort while driving may increase the risk of a crash. A worm gear is incorporated in the steering gear assembly, which transmits the power assist generated by the power steering motor. The worm gear friction force may be excessive which results in increased force required to turn the steering wheel.
Suspension of Delivery – Mazda
Dealer Action Requested:
Currently, there are approximately 10,954 CX-90 vehicles in dealer inventory or in transit to dealers. All Mazda
dealers must quarantine any affected new, used, or Certified Preowned Owned (CPO) in-stock vehicle until the repair is completed. The affected dealer inventory list is available on Mazda
Global Service Support (MGSS) and was provided to your District Service Manager. The current inventory list will be updated weekly or bi-weekly on MGSS as needed.
Repair Outline: Dealers will reapply grease to the gear teeth and will replace a spring with an improved part that reduces the spring force to the worm gear in the steering gear assembly. This repair was validated at MNAO and there is ample time provided for this recall to complete the repair and take the required photos. Technicians will be required to take 4 clear photographs of specific steps in the repair and those photographs must be attached to the claim for Recall and Warranty claim review prior to acceptance.

Chronology of Defect on January 18, 2024
Sudden increase in steering effort on MY2024 CX-90
Mazda #6524A
November 24, 2022: Mazda
received the first field report, from Japan.
December 12, 2022: Mazda
received its second field report, from Sweden. Mazda
began to investigate this condition.
March 1~29, 2023: Mazda
identified the root cause. It was due to pushed out grease from the gear teeth.
April 6, 2023: Mazda
implemented a countermeasure for production vehicles, which modified the teeth shape of the worm wheel to allow for proper application of grease to the gear.
April 30, 2023: Service information was issued in Japan and Europe, where several failures occurred to ensure dealerships were informed of the remedy.
September 27, 2023: The same failure occurred on improved parts, which had the updated worm wheel gear teeth shape. Improvement parts were found to be inadequate.
October 13, 2023: Mazda
examined the failure mechanism using the previously improved part and considered further improvement to correct this condition.
October 27, 2023 ~ Nov 8, 2023: Mazda
received three field reports from the U.S.
December 11, 2023: Mazda
implemented the permanent countermeasure on production MY2024 CX-90 vehicles, which reduced the spring force applied to the worm gear. Excessive spring force caused grease to be pushed out from the gear teeth resulting in lack of oil film. This caused the sticking condition.
December 13, 2023: Mazda
continued investigations and confirmed this condition does not cause the steering to lock-up or bind. Furthermore, the driver will feel a momentary increase in effort to steer which feels like a sticky steering condition.
December 22, 2023: Mazda
received two additional field reports from the U.S.
January 11, 2024: As momentary sticky steering may cause a loss of vehicle controllability, Mazda
judged this condition as impacting vehicle safety. Therefore, Mazda
held a Quality Audit Committee meeting to review all available information to date and approved a proactive field action on certain MY2024 CX-90 vehicles.
As of January 11, 2024, Mazda
is not aware of any reports of accident or injury related to this concern. Also, as of this date, five field reports have been received by the United States and/or Territory markets.

Attention: Mazda
General, Parts and Service Managers Subject: Announcement of Safety Recall 6524A- 2024MY CX-90-Sudden Increase in Steering Effort Dear Mazda
Dealer Partners, Mazda
Motor Corporation has decided to conduct a Safety Recall on certain 2024MY CX-90 vehicles. Please see the description, model, year, and VIN range below for the vehicles in this campaign. There are 43,695 vehicles affected with this concern in the US. SPECIAL REQUEST TO DEALER PARTNERS: For this recall and all safety recalls for Mazda
vehicles, it is highly recommended that the General Manager, Service Manager, and Shop Foreman (if applicable) meet with all technicians and remind everyone that the recall instructions must be read thoroughly and
performed exactly as they are written. Improper repairs caused by not reading instructions can lead to
incomplete repairs and put customers at risk when driving their vehicles.
Subject Vehicles:
Model I Subject VIN range I Subject production date range
From December 27, 2022, through
December 11, 2023 2024CX-90 JM3 KK ******100044-152900 Note: All powertrain types are affected (MHEV/PHEV) *Only the vehicles in this range and with a “Not Launched or Open” status in eMDCS are affected. Concern Outline: While driving, the customer may feel a sudden increase of effort when steering the vehicle. Sudden and unexpected change of steering effort while driving may increase the risk of a crash. A worm gear is incorporated in the steering gear assembly, which transmits the power assist generated by the power steering motor. The worm gear friction force may be excessive which results in increased force required to turn the steering wheel. Suspension of Delivery – Mazda
Dealer Action Requested:
Currently, there are approximately 10,954 CX-90 vehicles in dealer inventory or in transit to dealers. All Mazda
dealers must quarantine any affected new, used, or Certified Preowned Owned (CPO) in-stock vehicle until the repair is completed. The affected dealer inventory list is available on Mazda
Global Service Support (MGSS) and was provided to your District Service Manager. The current inventory list will be updated weekly or bi-weekly on MGSS as needed. Repair Outline: Dealers will reapply grease to the gear teeth and will replace a spring with an improved part that reduces the spring force to the worm gear in the steering gear assembly. This repair was validated at MNAO and there is ample time provided for this recall to complete the repair and take the required photos. Technicians will be required to take 4 clear photographs of specific steps in the repair and those photographs must be attached to the claim for Recall and Warranty claim review prior to acceptance. NOTE: As a reminder, failure to properly perform any recall repair is a direct violation of Paragraph 14(F) of the Dealer Agreement and can cause one or more of the following: Mechanical breakdown or failure, crash or injury, Dealership penalties/fines by Mazda
and NHTSA, increased liability risk for the dealership, Missed Recall penalties, loss of customer trust, and a poor Customer Experience. Additionally, vehicles sold by Mazda
Canada, Inc. and U.S. Territories are also affected by this recall and should be repaired if presented to your dealership. Parts: A limited number of repair kits containing grease, a tool, a spring and the other required parts is available, and a push shipment of kits is being sent to all dealers with affected inventory. Orders for additional kits are not available at this time. We anticipate before the end of January, a second push shipment will be sent to dealers as additional kits and vehicles arrive. By mid to late February additional orders will be available from the Limited Parts Ordering screen in eMDCS. For proper parts supply planning, a copy of the UIO by dealer will also be made available to your field management team. Mazda
Employee Lease/Corporate Vehicles: If you are a Mazda
employee responsible for or driving a 2024 CX-90, the Mazda
Recall Team will contact the person assigned to the vehicle directly by email when the repair is available. Instructions will be provided on where you can take the vehicle (a Mazda
Dealer or Mazda
Service Facility). If you have any concerns with your 2024 CX-90, please visit a Mazda
dealer or contact your corporate/regional vehicle coordinator. Owner Notification: All vehicles will show as “Not Launched” on January 22, 2024, by the end of the business day. The “Not Launched” status is required prior to mailing Owner Letters to customers, but this status does not mean do not repair. In stock vehicles showing “Not Launched” status must be repaired prior to customer delivery when parts are available. If the campaign is not complete, the vehicle cannot be delivered to a customer. Please read this entire email and check MGSS under this recall for updated instructions. Mazda will directly contact affected owners by U.S. Mail no later than March 18, 2024. To help you effectively perform this recall, Mazda has developed the following resources: 1. Parts and Warranty Information, Repair Procedure, and the affected VIN list are expected to be posted to MGSS on or before January 24, 2024, but may be delayed. When posted, searching by VIN is available immediately, but Keyword Searching may not be available until the next business day.
2. For Warranty questions, please contact the Warranty Hotline at [email protected]
3. For parts questions, contactthe Corporate Dealer Assistance Group at [email protected] or by calling (877) 727-6626 Option 2
4. For recall related questions, please fill out the Dealer Recall Help Form located on OneMazda. 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.

Do not use a metal pry tool or flathead screwdriver, as this will cause damage/ deform
the aluminum case. Deformation or cracking of the black cover will allow moisture
to enter the worm gear breaking down the grease resulting in rusted parts. Costs to

CX-90- Sudden Increase in Steering Effort
Dear Mazda Dealer Partners,
ACTION REQUIRED, REPAIR PROCEDURE UPDATE:
We appreciate the feedback on our requirements for this repair and recognize that the request for
multiple photos was a challenge. Based on this feedback, our continued partnership and the joint
desire to ensure all recalls are completed correctly, MNAO Warranty and Recall Operations are
pleased to announce changes to the repair procedure supporting this recall.
The repair procedure was simplified today, reducing the previous requirement of four (4) photos to
only one (1) specific photo that is required to be taken and attached to the warranty claim. Any
repairs or claims in process or not submitted, regardless of the date will only require this photo
to be attached.
Please ensure your technicians pull up the latest repair procedure to identify the required photo
and ensure the photo shows the items called out in the photo clearly. Please read all steps in the
document as there are other minor changes and warnings. The repair order is not required to be in
frame on the photo. The technician only has to write the RO# on the steering rack for
identification which is matched to the claim.
The Parts and Warranty information was modified to require only one D40 Photo requirement. If
you have any questions regarding this change please fill out the Dealer Recall Help Form located on
OneMazda. The repair time remains the same.
Please make certain the appropriate personnel in your dealership are aware of this
change and additional resources for this recall before responding to customer inquiries. We
apologize for any inconvenience this recall may cause you and your customers. Your
understanding and support in carrying out this campaign are greatly appreciated.
Sincerely,
Mazda North American Operations
