2024 MAZDA CX-90 Complaints

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.

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.

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)

Steering wheel gets stuck when holding turns like a left turn on stoplight, or freeway interchange. Have to forced the wheel back to straight.

When you turn, the steering wheel doesn't retract or turn back on it's own. You have to give it tug or jerk, which makes it dangerous.

Steering wheel still locks up after recall was done whenever turning wheel gets hard and almost doesn't Want to turn off of turning position to straight position

Following the remedy performed under recall 24V-022, the steering continues to exhibit intermittent issues. The wheel occasionally feels suddenly heavy or resistant, with a sticky, stiff sensation that builds gradually before returning to normal. This is most noticeable at speeds between 15–25 mph while simultaneously turning, such as navigating parking lots, intersections, or slow cornering. The issue also occurs unpredictably with no consistent trigger outside of those conditions. The problem persists despite the recall repair having been completed. The vehicle will be taken to local Mazda dealership (Modesto Mazda) to have re-inspected of issue.

The front passenger occupant detection system and seatbelt warning system may not function properly for lighter-weight passengers in the Mazda CX-90. When a front-seat passenger weighs approx. 90 pounds or less, the vehicle may not recognize that the passenger is present. In these situations: • The passenger airbag remains OFF. • No seatbelt warning or audible seatbelt alert is activated when the passenger is unbelted. • “Fasten Passenger Seatbelt” warning alarm is generated when the passenger exits the vehicle, the driver continues driving and seat is empty. This behavior has been repeatedly demonstrated and is easily reproducible. The same condition was also reproduced in a new 2026 Mazda CX-90 directly from a dealership lot and in a 2026 Mazda CX-90 loaner, suggesting this is not an isolated vehicle issue. My vehicle has been presented for service four times at three different Mazda dealerships. Technicians have observed the condition, Mazda regional technicians were consulted, and a manufacturer-recommended reconfiguration/recalibration procedure was performed. The condition remains unresolved. No diagnostic trouble codes are generated when this occurs. Because no fault codes are present, no repair has been offered. Mazda Corporate has advised that the vehicle is operating as intended and referred me to the owner’s manual. My concern is that lighter-weight front-seat passengers may not receive required seatbelt warnings because the occupant detection system does not consistently recognize them as occupants. Additionally, the system generates a seatbelt warning after the passenger exits the vehicle and the seat is empty, indicating a discrepancy between actual seat occupancy and system recognition. Mazda has reviewed multiple videos documenting this behavior in more than one vehicle. Despite this documentation and multiple service visits, no corrective action has been provided, and the condition continues to occur.
