My main complaint is the steering system. They had the recall fixed at a Mazda dealer in Tennessee before I purchased it. My steering wheel always seem to be crooked I took it to the dealer for an alignment that did not fix the issue of the car going side to side. I took it to three other shops for alignments and the car still seems to go in different directions no matter how correct they get the steering wheel. I also took the car to the dealership about the AC system making loud rattling like a can of nuts and bolts. I had five videos of the issue and let them see them and listen to them they had the car for approximately 32 days and returned it and told me there was no problem. While they had the car I had four different loaners 2025 and 2026 models and none of these models had any of the problems that my 2024 had. They were quiet and there were no issues with the steering rack. My arms actually get tired steering this car down the road because it always wants to go in a different direction it is not a hard steer is very subtle but it keeps you correcting the steering wheel from left to right the entire trip. After returning my car after a month of having it the AC was blowing very poorly and I took it back again. They evacuated the system and recharged it which seem to help however, now it seems to blow cold and then go back to warm sometimes blowing cold or if the car is just parked rather than going down the road. There have not been any warning lights or issues other than the general feel of the car wanting to go side to side when you get it going in a straight direction it wants to almost purposely go to the right or go to the left and then when you correct it it wants to go back to where it was it is very subtle. Lastly there are issues with the blind spot monitoring. In my previous Mazda it worked flawlessly and never falsely alerted me. However in this car the cx90 fails to notify me or sometimes notifies me when I'm sitting still next to a tree.

Over my time owning this vehicle i have had several different safety concerns. although they have been resolved by the dealer, i have concerns for anyone purchasing this make and model. 1. lane departure. i have turned off lane detection because i have had the car try to auto correct and jerk me to the left into oncoming traffic 2. i have had incidents where the driver door was unable to be opened from inside. i had to roll down the window to open the door and get out 3. At a speed of 45mph, the vehicle suddenly went into limp mode. the car turned off and luckily i was able to pull over into a safe area. again i experienced the door locking from the inside. all issues and solutions have been documented at dealer services. these issues are of great concern and potentially could have been harmful or fatal. i no longer have trust in this model or company.

The vehicle lurched to a complete stop and engaged the parking brake while entering the on ramp at FDR bridge in NYC. I had my whole family (7 of us) in the vehicle. Cars behind us had to slam on the brakes or swear to not hit us. The worst part is, the car had no option to put it into neutral to move the vehicle to a safe location. I sat praying for 45 minutes while we waited for a tow truck. Cars were flying past us as we were blocking 2 lanes of traffic, one of which was the on ramp. They could not see us as they were coming around a corner. Several accidents almost happened. There was nothing we could do but sit there. This is a known issue with Mazda CX 90 2024 PHEV system. Mazda did not warn me in any way that if the vehicle has an issue with the PHEV system, it was going to disable the vehicle to the point that you are unable to put it into neutral. There was no way to disengage the parking break. The vehicle was towed twice with the break engaged.

On May 2, 2026, I took my 2024 Mazda CX‑90 to Mazda of Orange because the steering wheel was getting stuck and there was a loud chirping noise when turning the car on and off. The dealership kept my car for 28 days. When I picked it up, they told me the noise was fixed. After three days, the noise returned. The next morning, the car would not start, so I had to jump it and take it back. They said it was the brake assembly line and claimed it was safe to drive when it wasn’t. They also said the bottom battery was giving errors. I had already replaced the top battery in April 2026 for $300, and they replaced the bottom one under warranty. When I brought it in, all dashboard warning lights were on, and the car warned me not to drive over 30 mph. They replaced the battery again but could not explain the warning lights. This was my sixth visit, and they kept blaming rain or fog even when the weather was clear. Two weeks after getting the car back, all warning lights came on again on [XXX]. At [XXX], while taking my husband to the airport, I was afraid to turn the car off. I hit a bump, the lights turned off, then came back on — which makes me think there is an electrical short. Now the transmission jerks hard, especially when the i‑Stop activates. I bought the car in April 2025; it has 47,700 miles, and I have taken it in six times. [XXX] from the mediation department told me he would start a buyback on June 20, 2026, but he is now ignoring my calls. Name: [XXX] VIN: [XXX] Case #: [XXX] License Plate: [XXX] Vehicle: 2024 Mazda CX‑90 (factory warranty still active) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On March 27, 2026, while driving approximately 20-35 mph on a city street in clear daytime conditions, my vehicle unexpectedly activated Smart Brake Support (SBS) and applied the brakes hard enough to bring the vehicle to a complete stop. There was no vehicle directly in front of me and no obvious obstruction that would have required emergency braking. Immediately prior to braking, the vehicle displayed brake warnings and alerts inside the cabin. The sudden braking created a safety risk because the vehicle came to a complete stop in an active travel lane without warning. Had another vehicle been following closely, a rear-end collision could have occurred. The event was reported to my Mazda dealership, Herzog-Meier Mazda, on March 30, 2026, the next business day after it occurred. The dealership advised that the vehicle should not have behaved this way because the applicable software update related to the Smart Brake Support system had already been installed. The vehicle was subsequently returned to the dealership for further investigation on April 22, 2026, and remained there for an extended period while Mazda reviewed the incident. Mazda regional technical personnel reviewed vehicle data and confirmed that Smart Brake Support activated during the event. Mazda's conclusion was that the system operated as designed because vehicle data indicated a perceived collision risk. However, Mazda also stated that no camera footage from the event was retained and that the surrounding conditions could not be independently verified. As a result, Mazda was unable to identify what specific object or condition triggered the emergency braking event. No repairs were performed, and Mazda recommended returning the vehicle to service. The Smart Brake Support system remains available for inspection. The event has been reviewed by the dealership, Mazda regional technical personnel, and Mazda Customer Experience. No defect was acknowledged by Mazda, despite the unexpected full braking event

The vehicle started to hydroplane in rain on the highway and the lane keeping assist aggressively tried to push me back, which ended up causing us to hydroplane more and causing the vehicle to flip around backwards and we ended up sliding completely off the highway into a ditch totaling the vehicle.

There is a recurrent steering wheel issue. The issue was first addressed during the national recall campaign 6524A / the federal safety agency 24V‑022 where it received the recall repair. The exact same dangerous issue has returned. The issue currently, is best described as having to wrestle with the steering wheel at all speeds when minor corrections are needed. That is, the steering becomes binding, catching, and creating a ratcheting sensation in both low speed maneuvers and at minor corrections during highway driving. This constant position "sticking" of the steering wheel requires me to physically pull and jerk the wheel to break it free from its position; hence the "wrestling" analogy. The vehicle was not received immediately at the dealership due to "work backlog". It is pending current review of the recurence of this symptoms.
