Mazda CX-90 grinding brakes problems

Filed Jul 14, 2026 · Engine, Fuel system · CA

I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving. I have taken the vehicle to the selling/authorized Mazda dealership on two occasions — June 2, 2026 and July 14, 2026. On both visits, the dealer was able to reproduce and confirm the noise and knocking. The dealer stated they are aware other customers have reported the same issue, but that Mazda considers the noise/knocking acceptable and declined to perform a repair. No warning lights or diagnostic trouble codes have appeared at any point; the only symptoms are audible and physical. The vehicle is under both factory warranty and a purchased service/maintenance agreement. It has only been inspected by the selling dealership; no inspection has been performed directly by Mazda North America, law enforcement, or an insurance representative. I am concerned about my safety and the safety of others because a worsening, unexplained drivetrain issue that produces hard knocking and vibration during routine driving suggests a mechanical fault that could progress to sudden failure, and the manufacturer has declined to investigate or repair it further despite the symptom escalating across two documented visits. The vehicle remains available for inspection upon request.

When I was parking in a CVS parking lot, the brakes failed and the car kept rolling and the brakes wouldn’t work. My car was rolling into traffic so I turned and accelerated to swerve from traffic. In doing that, the passenger side scrapped against a tree and I the brakes finally worked and I was able to start the car. I was shaking like a leaf and totally in shock. T hen I went online to see if there is a problem with the brake system. I’ve always been a little hesitant because the brakes squeaked from day 1. The car is leased and I hardly drive it so I needed a a possible causefor the malfunction.

Every time I drive the vehicle, it basically snatches me back into the lane aggressively. If I am moving into the next lane, the lane correction is so aggressively, I am afraid it is going to cause a collision. The brakes squeak and squeal constantly. They have oiled the brakes but it didn't work.

Steering wheel became stuck when making a long left turn while driving on the freeway. The turn lasted approximately 30 seconds. Around 3-4 seconds into the turn, the steering wheel suddenly locked up for approximately 1-2 seconds. Eventually the steering wheel was released resulting in a sudden jerk, leading to the car veering to the right lane. A correction was made using the steering wheel to maintain center lane. Once again the steering wheel got stuck, resulting in the same jerk behavior. This occurred three times in the 30-second turn. I have not attempted this route since this incident. Prior to this incident, the front end suspension made a grinding noise when turning the steering wheel left (e.g., backing up into the garage). There is minor vibration on the steering wheel but not too noticeable due to the low speeds. A recall was previously performed back in 2025 to correct the grinding suspension. However, it returned several months after along with the minor steering wheel issue. I plan to report this at the next scheduled maintenance interval.

When I’m driving, the steering wheel suddenly gets stuck and pulls against me with force. This is extremely dangerous, especially on the freeway or when going over a bridge — the car pulls in the opposite direction of where I’m steering. The brakes also start squealing very loudly. It feels like the steering wheel is about to lock up while I’m driving, and I’ve had to physically fight it to keep control of the car. This is a serious safety risk, and it feels like the vehicle could lose steering at any moment.

Hybrid battery failed causing electrical issues. - Fix in October 2024. During this time Service repair for the recall related to the power steering. Car became jerky and would lose the ability to hold turns. Took to mazda and told there was a gear housing need to be replaced. Was quoted at 4000 for the repair due to car having 49000. Mazda customer service stepped in and dropped the price in half. Eventually cover the majority of the cost as we reported this as a safety issue and it only camp up after the recall was performed for the power steering and the suspension was fixed. In the service report, Technician stated that the steering has fuse to the sway bar. I am now very concerned the sway bar is unsafe. Mazda did not comment on this when I ask. It appears as the fix one thing more continue to break. with The issues the lane assist continues to have issues seems to struggle with alignment issues. Car was with Mazda for 7 weeks during the 1st year of owning it. I am also concerned with some of the finding as I look at them with details pertaining to original purchase and miles being reported on our documents. Living in Kentucky the Lemon law does help with providing any sort of real action plans on CPO. Break have been squeaky causing uneven feedback. This issue has worsened over time. Car was purchased CPO - in April of 2025.

Component/System: Steering System (Electronic Power Steering / Steering Rack) What happened? I am experiencing a recurring and escalating failure of the steering system on my Mazda CX-90 PHEV. Currently, the steering wheel momentarily "locks up" or experiences a sudden, significant increase in resistance (stickiness) during left turns, especially when a large steering angle is applied. This occurs intermittently and without any warning lamps or error messages on the dashboard. Safety Risk: This failure poses a severe safety risk as it hinders my ability to complete turns smoothly and predictably. The sudden resistance requires unexpected physical effort to overcome, which could lead to a loss of vehicle control or a collision, especially in tight maneuvers or emergency situations. History & Inspection: Previous Symptoms: Approximately one year ago, the vehicle exhibited a "grinding/squeaking" noise when the steering wheel was turned to full lock. Prior Repair: A dealership inspected the vehicle and performed a recall repair (related to Recall 24V‑022) by applying grease to the steering components. This temporarily resolved the noise. Recurrence: The noise has recently returned, and the new issue of "momentary locking" has now emerged. Inspection Status: The vehicle has been previously inspected for the related recall, and the current malfunctioning system is available for inspection upon request. Additional Context: I am reporting this because I believe the initial recall fix (grease application) was insufficient, and the vehicle is now demonstrating the "sticky steering" symptoms currently under the federal safety agency investigation (RQ26002).

On April 29, 2026, my 2024 Mazda CX-90 Turbo S Premium Plus experienced a steering malfunction while I was entering a right turn. The vehicle had Mazda steering recall 6524A / the federal safety agency Campaign 24V‑022 marked closed/completed before this crash. I was traveling on a familiar road and attempted a normal right turn that I make regularly. As I attempted to turn, with no warning lamps, warning messages, or prior warning immediately before the incident, the steering wheel suddenly required abnormal effort, felt stuck, and would not turn normally. I was in complete shock from the sudden steering issue and abnormal resistance. The vehicle then struck the curb, left the roadway, and traveled down an embankment/grade of approximately 15 feet into a residential yard. The crash involved significant driver-side/front-left damage. The front driver-side wheel/tire separated and was found near the vehicle. The driver-side airbags deployed. Scene evidence included curb/edge impact damage, debris, and a deep ground-level rut/indentation below the roadway. This incident placed me and others at serious risk because the vehicle left the roadway and entered a residential property. The vehicle and failed components are available for inspection upon request. To my knowledge, the only prior inspection or repair related to the steering system was performed by the Mazda dealership in December 2025, when recall 6524A was marked closed/completed along with other recalls. The vehicle has not yet been independently inspected for this crash-related steering concern. Before the crash, the vehicle had multiple issues and spent significant time at the dealership for recall and non-recall repairs. One ongoing issue was a brief grinding/rubbing noise when accelerating from low speeds, which existed before the dealer work and continued afterward. Mazda/dealer indicated this low-speed grinding/rubbing noise was a known reported issue with no fix at that time.
