What 308 owners told NHTSA about the 2024 Mazda Cx-90-mhev

Vehicle has a history of steering rack failure (recently replaced; May 22nd 2026). During the same service visit, the authorized Mazda dealership formally documented that this vehicle is affected by Mazda Customer Satisfaction Program 14 (CSP 14) for a critical brake defect. However, the dealership returned the vehicle to me without performing the safety repair, forcing me to drive a vehicle with a known, un-repaired brake defect. This issue is directly related to the open NHTSA Query RQ26002 regarding Mazda steering and braking systems. The manufacturer has failed to cure this defect within a reasonable timeframe, posing an ongoing safety risk.

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.

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.

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.

1) What component or system failed? The issue appears to involve the vehicle’s electrical system and hybrid system, as well as brake-related electronic systems. The vehicle displayed multiple warnings including “Hybrid System Malfunction” and “Critical Vehicle Malfunction.” The electronic parking brake system was also affected during the incident, including a situation where the brake could not be released while the vehicle was in motion. The affected components are available for inspection upon request. 2) How was safety put at risk? Safety was put at risk because the malfunction occurred while driving and involved critical system warnings and brake-related issues, including the inability to release the electronic parking brake. The sudden appearance of a “Critical Vehicle Malfunction” warning during operation created concern about potential loss of vehicle control and safe braking capability in traffic. 3) Has the problem been reproduced or confirmed by a dealer? The issue has not been fully resolved. The vehicle previously underwent service for a high-voltage hybrid battery replacement, but the current symptoms continue to occur repeatedly. The problem has not yet been confirmed as permanently resolved by the dealer. 4) Has the vehicle been inspected by manufacturer, police, insurance, etc.? UNKNOWN 5) Were there warning lamps or symptoms before failure? Yes. Over the past two weeks, multiple warning lights and messages have appeared almost daily, including: Check Engine Light Hybrid System Malfunction i-Stop malfunction Intermittent brake / electronic parking brake warnings A “Critical Vehicle Malfunction” warning occurred once while driving, along with multiple simultaneous alerts.

I have a 2024 Mazda CX-90. I want to report that about two years ago I was contacted regarding a recall (or possibly multiple recalls). The steering would become stiff while turning on curves. I took the vehicle to the dealer, and they reprogrammed something, which fixed the issue for a few months (I don’t remember exactly how long). However, the same problem happened again about three times. I brought the vehicle back to the dealer on January 23, 2026, and they did not have the necessary parts to repair it. I told them I was very afraid to drive the vehicle in that condition because the steering would get stuck when turning on curves, and I was worried that one day it could cause a serious or even fatal accident. The dealer told me they could not do anything at that time. It took 65 days for them to replace the parts, and it was very stressful driving under those conditions. Even after the repair, the vehicle does not feel right. I feel that the steering still moves abnormally, and I am very afraid to drive it like this. Additionally, the brakes sometimes make a strange noise. I don’t know what to do about this situation. I would like to return the vehicle, but I don’t know how, especially since the dealer is no longer responsible. I need help.

Incident 1: While driving my 2024 Mazda CX-90 PHEV at low-to-moderate speed, the vehicle suddenly and completely locked up without any driver input. There was no gradual slowing or normal braking behavior. Instead, the vehicle went immediately from moving to an abrupt, forceful stop, as if maximum braking was applied instantly. There were no warning lights, alerts, or audible signals before or during the event, and there were no obstacles or vehicles in front of me. Incident 2 (approximately 6 months later): A second, nearly identical event occurred while I was accelerating or cruising. The vehicle again immediately locked up and came to a sudden stop with no warning and no driver input. There was no progressive braking or deceleration. The stop was instantaneous and extremely forceful, causing me to lurch forward into the steering wheel. There were no hazards or objects present that would justify emergency braking. Additional Details: Both events involved an immediate, full-force stop with no transition or gradual braking. There were no dashboard alerts, warning sounds, or messages during either incident. The behavior did not match any known system alerts (such as door open or limp mode). The dealership was unable to reproduce the issue and found no diagnostic trouble codes. This creates a serious safety risk, especially the risk of being rear-ended during normal driving.

The service brake system on my 2024 Mazda CX-90 produces a loud, high-pitched squeaking noise during normal low-speed braking, including when stopping at traffic lights, reversing, and parking. The issue has been present and occurs daily under normal driving conditions. The brake pads and rotors are available for inspection upon request. The squeaking reduces my confidence in braking performance and causes me to alter my braking behavior, particularly in stop-and-go traffic and when braking near pedestrians. In a vehicle used daily for family transportation, unreliable or degraded brake performance puts my safety and the safety of my passengers and other road users at risk. The problem has been reproduced and confirmed by an authorized Mazda dealership. On February 25, 2026, I brought the vehicle to Gunther Mazda for this issue. The dealer attempted to address the brake noise at no charge but acknowledged this is a known issue related to the brake pad material and stated no permanent repair is currently available. A copy of the repair receipt from this visit is available. I also contacted Mazda Motor of America directly. A case manager was assigned and confirmed the issue is known across the CX-90 model. Mazda offered a $250 service credit but provided no repair or resolution. Mazda issued Service Alert SA-016/24 (Brake Noise, Judder and Dragging Diagnosis and Servicing) acknowledging brake noise, judder, and dragging on the CX-90 and other models. Despite this bulletin, the dealer repair attempt has not resolved the issue. There are no warning lamps or dashboard messages associated with this condition. The squeaking began at low mileage and has persisted continuously since first noticed. The issue is not intermittent; it occurs with regularity during routine braking.

Reporting multiple safety-related defects on my 2024 Mazda CX-90. Steering system: At approximately 5,000 miles, the vehicle developed abnormal steering behavior, including inconsistent steering response and abnormal feel during normal driving and turning. The condition affected my ability to steer the vehicle predictably and raised safety concerns, particularly during low-speed turns, parking maneuvers, and city driving. The issue was confirmed by the dealer and required replacement of the steering rack, a major steering component. The vehicle remains available for inspection upon request. Hybrid system: At approximately 22,000 miles, the vehicle experienced a hybrid system malfunction that required the vehicle to be taken out of service for an extended period. The malfunction affected drivability and reliability and required dealer diagnosis and repair. The vehicle was inspected and repaired by an authorized Mazda dealer. Braking system: The vehicle has experienced ongoing abnormal brake squeaking during normal driving and low-speed braking. While braking function remains present, the abnormal noise raises concerns about brake system integrity, wear, and long-term braking performance. Electrical / infotainment system: The infotainment system intermittently shuts off or resets while driving without warning. When this occurs, the display goes blank and then restarts. This results in loss of access to navigation, rear camera display, vehicle settings, and driver-assistance information, creating driver distraction and a potential safety risk. These issues occurred on a relatively new vehicle and involve critical systems including steering, drivetrain/hybrid, brakes, and vehicle electronics. The combination of defects raises concerns about vehicle safety, reliability, and loss of driver confidence. Warning messages were present for the hybrid malfunction; other issues occurred without warning. The vehicle has been inspected and repaired by authorized Mazda deal
