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

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.

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)

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 / NHTSA 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.

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.

Stick steering wheel. Excessive force need to steer while making a turn.

At highway speeds, even with lane keeping assist disabled/turned off, if the ADAS is turned on LKA seems to remain active. Steering effort is unpredictable making it difficult to maintain a line through the corner. Effort will suddenly decrease resulting in oversteer. This is particularly dangerous when next to other cars, guardrails, barriers and the like. The behavior is greatly reduced with all ADAS off. This is largely repeatable over the last 18 mos/24,000 miles.

I am reporting a serious steering safety issue. I was told a steering recall had already been fixed before purchase. About four months later, the steering wheel began locking or strongly resisting movement while driving on curvy roads at speeds over 50 mph. When this happens, the wheel does not return to center and requires force to correct, creating a loss of steering control. I took the vehicle to Passport Mazda in Maryland on January 2, 2026. The dealer stated the entire steering wheel panel needs replacement and the part is backordered until March 2026. This is a dangerous defect in a recently recalled system and needs investigation.

There is a potential safety risk with the 2024 Mazda CX-90 power steering/lane keep assist. When traveling at moderate speeds steering left into a turn the vehicle jerks to the right. I do not believe this is a direct problem with the lane keep assist as the problem only occurs when in the center of the travel lane and not while on the edge of the road. Lane keep assist works as intended when on the edge of the road or on the center stripped line as I feel a gentle assist again as intended. The hard pulling to the right problem only occurs when steering left into a turn. There are no warning lights on the instrument cluster. The authorized dealer has not been able to reproduce the issue. The issue has been ongoing for at least the past six months.

The lane assist safety feature stops working. The car will allow drifting across well-marked lanes, despite being a clean car and a clear weather day. The car will not attempt to keep the car in the lane. The events are unpredictable. I have checked the settings when it has happened and they all appear to be the same - the lane assist and related boxes remain checked, etc. After turning off the vehicle for an hour or two, the system seems to reset and work again. This has happened twice that I know if, but could have happened at other times that I did not notice.
