2024 Mazda CX-90

The Office of Defects Investigation (ODI) has received 26 complaints and several Early Warning Reporting (EWR) Field Reports alleging intermittent and brief increases in steering effort (described as “sticky steering”) during the drive cycle in model year (MY) 2024 CX-90 vehicles manufactured by Mazda North American Operations (Mazda) subject to Recall 24V2022. In each complaint, the vehicle had the recall remedy completed prior to the reported incident. Recall 24V022 addresses a sudden and unexpected change of steering effort while driving caused by excessive worm gear friction force. After receiving the recall 24V022 remedy, consumers report sudden increases of steering effort while driving. Sudden and unexpected change of steering effort while driving may increase the risk of a crash. ODI is opening this Recall Query (RQ) to assess the adequacy of the remedy for Recall 24V022 and to identify the cause(s) of the conditions leading to the post-remedy reports. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

Around 69,000 miles, radiator started leaking. This is a known issue with this vehicle due to failure of factory crimping machine. Multiple open lawsuits related to this failure. This is a major safety concern as the vehicle could overheat and catch fire or explode. No recalls issued, but more and more complaints and failures reported.

Problem statement: Steering wheel binds up when turning, felt mainly 35+ mph while turning on and off highway on/off ramps. 36k miles on odo. The dealership (Burdick Mazda) took the vehicle and provided a loaner, confirmed the problem and made the repair. The component replaced was the power steering rack and pinion system. The replacement fixed the issue. There was no pushback from either the dealer or Mazda and we were pleased with the results. There were no warning lights or other indications of the issue other than the binding itself. I am making this report only because this seems so be a greater concern for the vehicle based on research and wanted it reflected in the record. It is a safety issue as steering components are critical. Thank you.

When driving around turns where the steering wheels turns more than 50 degrees, the steering struggles to return to straight and is sticky. Along roads with horizontal curves, I must pull back to center when trying to exit a turn as the wheel is sticky (wants to stay at the angle needed to turn)

My 2024 Mazda CX-90 was purchased brand new with four original Toyo Open Country A51 tires, size 265/55R19. After only 24,291 miles, all four tires developed severe and uneven outer-edge tread wear, despite regular tire rotations approximately every 4,500 miles. On XXX, DeMontrond Mazda in [XXX], inspected the vehicle and officially documented abnormal outer-edge wear on all four tires. The tread measurements were 3/32 inch on the right front tire and 4/32 inch on the other three tires. The dealership recommended replacing all four tires and performing a complete wheel alignment. Photographs also show visible cracking on the worn tread area. I am concerned about loss of traction, especially on wet roads, and the safety of the vehicle and its passengers. I contacted Toyo Tires and Mazda Customer Service, but neither agreed to provide warranty coverage or replacement assistance. I am requesting a safety investigation to determine whether the premature and uneven wear is related to a tire defect or a vehicle-related issue. The cause has not yet been determined. I have the dealership inspection report, photographs, and maintenance records available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 02-003/26 09/04/26 and 06/24/26 Some vehicles have reported faster than expected tire wear for vehicles equipped with OEM "Falken 275/45/21" tires, without outside influence such as low tire pressure or out of specification alignment, and the tire life may not meet customer expectations. To eliminate this concern, the tire contact patch pressure has been optimized. REPAIR PROCEDURE Verify the customer concern (inspect the tires, verify tread depth, and replace all the tires as required on the vehicle according to the following "Inspection Requirements" and the instructions in MGSS (WHEEL AND TIRE REMOVAL/INSTALLATION). Mazda Warranty is providing case by case goodwill processing information regarding tire wear complaints on CX-90, and CX-70 vehicles equipped with OEM 21” 275/45/21 Falken tires. This goodwill assistance process does not include any other tire brand or size.

For vehicles equipped with the Accessory Tow Brake Controller (P/N: C9N1V7782A), the 12V battery may become discharged due to high parasitic current if the vehicle is left unused for an extended period, regardless of whether a trailer is connected or not. This may be caused by power supply to the controller continuing after the ignition is turned OFF due to inadequate software in the Tow Brake Controller. 5. Replace the accessory with the improved part (suffix "B"), and verify that the parasitic current is 65 mA or less. NOTE: For accessory installation procedures, refer to INSTALLATION INSTRUCTIONS in attached.

Subject: Update – Campaign Warranty Claim Response Enhancements – Modules Not Repaired for Certain Campaigns Dear Mazda Dealer Colleagues, On October 28, 2026, a change was implemented in the warranty claim response screen to provide precise information for all campaigns requiring module programming or module replacement subject to the LECS system software checks. As previously announced, some claims were automatically rejected with the Edit code JN1 – One or More Modules Are Not Updated when submitting a campaign warranty claim. This response was based on the session file received from MDARS or MDARS II at the dealership and the VIN on the claim submitted. This change provides additional Related Information which enhances the edit code information. This information allows the dealer to correct the error without contacting Warranty or Hotline. Edit code JN1 now contains the actual module name and the software version that was collected from the car and what the minimum required software needed to be for the claim. Using this information, the technician can now identify the exact error or errors and correct the concern.

This bulletin supersedes the previously issued bulletin(s) listed below. The changes are noted in Red. 02-001/26 04/29/26 Some customers may complain that an abnormal noise is heard from the front suspension when driving on rough road surfaces or when passing over speed bumps. This is caused by insufficient heat resistance of the bushing material under specific operating conditions, resulting in cracking and fluid leakage in the front lower arm bushing. To eliminate this concern: The bushing material has been changed to a heat-resistant material. The bushing shape has been modified to reduce deformation. The damping characteristics of the front lower arm bushing have been modified. REPAIR PROCEDURE 1. Verify the customer concern. If noise is detected, replace the front lower arm (rear side) according to the instructions in MGSS. CX-90 (FRONT LOWER ARM REMOVAL/INSTALLATION) CX-70 (FRONT LOWER ARM REMOVAL/INSTALLATION) If NO noise is detected, this TSB is NOT applicable. NOTE: Perform repairs on the affected side only.
