ENGINE
While the car was being repaired for the rear brakes issue that was covered under the recently announced extended warranties, the Mazda dealership stated there is also a radiator leak that should be repaired for $1,800. After researching online, it didn't take long to learn that this is another known issue with Mazda CX90s but hasn't been formally recalled at this point. I have no complaints with the dealership I purchased the vehicle from. The complaint is with the manufacturer for yet another known issue on the CX90s that is not a normal maintenance for a 2-3 year old vehicle.

ELECTRICAL SYSTEM, ENGINE
There was a recall issued within the last year for my make and model vehicle, in March 2026, it was fixed when my car was towed to a Mazda dealership due to a check engine light and "hybrid engine malfunction". On June 24, 2026, the vehicle went into limp mode, the error message resolved upon turning off the vehicle. There were no check engine lights that appeared. On June 25, 2026, the vehicle went into limp mode on I-5 in traffic. We were able to safely get the vehicle to a safe location out of traffic. The error code on dash was "hybrid engine malfunction" again. The radiator was replaced at a second Mazda dealership, we were told "that should fix the problem". There was no indication the radiator needed replaced due to no fluids leaking and no overheating of the vehicle. The battery did fail during this visit. On June 26, 2026, when we were on I-90 in traffic again, the vehicle went into limp mode again with the same hybrid engine malfunction warning. The vehicle was towed to a third Mazda dealership to finally have the hybrid battery finally replaced. The only warnings were when we went into limp mode, no dash lights or check engine lights, nor overheating. The safety of my family was put at risk due to the vehicle decelerating from 75 mph to 35 mph in the fast lane of traffic twice. Mazda has done all service repairs and recalls.

The lower fuel pump is going out. It is a known issue with the car. I was driving out of town and the car started to stall. My steering has become ruggish while on the trip as well, and steering was complicated during heavy winds. The car has been inspected by dealer and both warning lights have been cleared. But the issues still remain.

ENGINE, ELECTRICAL SYSTEM, LANE DEPARTURE: WARNING
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.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: WARNINGS
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.

SERVICE BRAKES
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.

SERVICE BRAKES, STEERING, LANE DEPARTURE: WARNING
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.

STEERING
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.

SEAT BELTS
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.

STEERING
Few months after the steering recall we started experiencing issues with increased resistance while turning the steering wheel. Sometimes the steering is not very smooth. Was told the solutuon to this issue was a other repair that was not covered under the recall. Unfortunately we are past the 36k mile warranty.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
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

STEERING, SERVICE BRAKES
Just purchased this vehicle and find the steering to be tight, jerky, and when on the freeway and there is a connector joint where two sections of road meet the vehicle veers almost to the next lane. And when applying the brakes when exiting at freeway speed brakes shudder. The vehicle has had the recall #6524A done but the steering is still dangerous. Brake fix is supposed to be addressed soon by Mazda. Vehicle is a lemon.

ELECTRICAL SYSTEM, VISIBILITY/WIPER
Instrument cluster will reboot during braking at random times. All warning lights turn on, gauges go to zero and front wipers are set off. This happens for 1-3 seconds. Mazda replaced instrument cluster but only made issue worsen they said it’s safe to drive but very distracting especially when turning onto busy roads. Currently being experienced by multiple other vehicles, so not isolated. Bought in February 2026 and started in early March 2026, currently still an issue as of June 2026.
