2025 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.

The tires on my 2025 CX90 where declared by the dealership to be unsafe/worn at only 20,000 miles. They told me the tires are well into the red zone for replacement. The problem was confirmed by the dealer where I brought the car. The tires are Toyo open country. Evidently Mazda issued a TSB for the Falkan tires that are also failing early. Mazda and the tire manufacturer are well aware of the problem. They have offered to give me 50% off a new set (not to include mounting, balancing, etc.) of the same tires which will only wear out quickly like the current set. The challenge is neither the dearlership or Mazda will help with purchasing other tires that will wear longer and since there are so few tires that will fit the CX90 I feel my concerns are not being addressed. I do not want to buy another set of faulty tires - the internet is full of consumers discussing this very issue.11

At roughly 15,000 miles, the OEM Falken tires experienced severe, premature tread degradation down to the cords under regular driving conditions. Mazda is aware of the defect, as documented in TSB 02-003/26 regarding higher-than-expected wear rates on these factory tires. Driving a 5,000-lb SUV with compromised tire integrity presents a severe safety hazard, including catastrophic highway blowout and loss of control. Mazda has avoided a formal safety recall by classifying the repair as limited 'goodwill assistance' while denying warranty reimbursement to affected owners. This widespread tire defect on heavy vehicles warrants immediate regulatory investigation.

275/45R21 Falken ZIEX ct60a A/S Hi, Yesterday I went to my Mazda dealership to get an oil change and was to told my tires are at 4/32 backs 6/32 fronts Falken ZIEX ct60a A/S 275/45R21 I bought my 2025 Mazda CX90 PHEV on 8/1/25 and has 13020 as of today. They told me Mazda and Falken have a settlement agreement and know the tires are faulty BUT wont replace for free till 3/32.. I told them I don't feel safe driving on these tires and Falken acknowledge the tires have an issue they should be replaced before our Wisconsin harsh winters.. BUT they wont till the trend goes to 3/32. The dealership wants me to replace these tires now as we have harsh Wisconsin winters and these tires wont be safe to drive on for the upcoming winter and because the CX90 is so heavy they don't think with this trend it would have stopping issues on these tires.. I've never heard of tires going so bad so fast. Can you please help.. Thank you

I was driving on the freeway at about 60mph with my family in the car (kids in backseat). The sunroof spontaneously exploded (sounded like a gunshot went off in the vehicle). Most of the glass shot upward and behind us. The sunshade was closed so no one was injured, but this is a huge safety hazard to drivers in the vehicle as well as behind us on the road. The dealer is trying to pass it off as a rock hitting the windshield. I suppose there is no official way to prove whether this did occur, but EVEN SO, in any event, if a rock caused the sunroof to EXPLODE as opposed to just shattering or chipping that is a huge manufacturing safety issue. Sunroofs should never explode. The car is currently sitting at the dealer, I'm going to request a formal inspection.

The steering seems to be malfunctioning and is hesitant or sticking when operating the vehicle. The steering wheel seems to hesitate or stick only during left hand turns, even slight ones. If you do not manually pull the steering wheel back after turning, it will stay in the position and not return as it should. This issue posses a severe safety risk to my family and others if the steering component does not perform properly. An accident could easily occur as a result of this issue. The issue has not been confirmed by an authorized dealer yet. I am taking the vehicle to a Mazda dealership in the next week or so. No warning lamps or messages occur prior to or during the issue. This issue was first noticed 9/21/26.

I stopped for gas and when I removed the gas cap air came of out of the filler pipe like it was under high pressure. I could not fuel the vehicle because of the force of the air coming out of the tank blew gas out and shut off the pump. I started and shut off the car numerous times without the gas cap on and with it on which did nothing to affect the issue. It finally stopped after turning off all fans, radio and all accessories in the car and starting it without gas cap. The symptom lasted for more than 25 minutes. When I took my vehicle in for service they told me it was due to temperature change. I have not experienced anything like this with any other vehicle.

The vehicle utilizes I-Stop, which comes on when stopping and while traveling down the interstate when the computer isn’t registering throttle input as a way to increase fuel economy. At least a dozen times now, the vehicle has failed to register throttle input, which isn't allowing the vehicle to restart when traveling down the road. The tachometer will remain at zero even with the pedal all the way to the floor. This has even happened while traveling down [XXX] in Northern Virginia placing myself and my family at risk of a collision. We have taken the vehicle in for service and mazda has been unable to replicate the issue or successfully diagnose the problem.

My 2025 Mazda CX-90 PHEV has experienced multiple incidents of sudden, uncommanded hard braking when there was no visible obstacle or danger in front of the vehicle. The most serious incident occurred on September 4, 2026, during rush hour traffic. The vehicle beeped, a warning that said "BRAKE!!" appeared on the dash, and abruptly braked without driver input, creating a significant rear-end collision risk. My dog was thrown from the back seat as a result of the braking. Another unexpected braking incident occurred the following morning when I was backing out of my driveway. Similar unexpected braking behavior has occurred earlier in my ownership of the vehicle as well. I brought the vehicle to a Mazda dealership for diagnosis on September 10, 2026 (their earliest available appointment). They kept and tested the vehicle, but were unable to reproduce the condition or identify a cause. No repair has been made that explains or corrects the unexpected braking. On October 2, the dealership informed me that the vehicle was ready to be picked up and that they considered nothing to be wrong with it. The service manager, Rocky, told my husband that a "critter or shadow" could have caused the braking. I did not observe any squirrel, pedestrian, vehicle, object, or other hazard in front of or behind the vehicle during the incidents. I remain concerned that the vehicle may unexpectedly apply the brakes again, particularly in traffic and/or with my young son in the car. I do not feel comfortable driving it with my family while the cause is unidentified and no repair has been attempted. Mazda has been notified of the issue and I have requested a repurchase/buyback of the vehicle.

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.
