The 2024 Mazda CX-90 faces an NHTSA probe after drivers report heavy steering and loss of power assist. Get the latest details and find out what owners should do now.
U.S. safety regulators have opened a formal investigation into the 2024 Mazda CX‑90 after a growing number of owners reported that the vehicle’s steering feels unusually heavy and, at times, does not return to a neutral position. The probe follows a recall earlier this year that was intended to fix a similar issue.
What triggered the NHTSA inquiry?
In early 2024 Mazda issued a recall for CX‑90 models built that year, citing a “stuck steering wheel” problem. Engineers traced the fault to the screw‑type gear assembly inside the electric power‑steering (EPS) system, which could generate abnormal friction under certain driving conditions. The remedy involved lubricating the gear set and installing a software update designed to detect the fault before it manifested.
Nearly two years later, Mazda and its customers are still seeing the problem reappear. The National Highway Traffic Safety Administration’s Office of Defects Investigation (ODI) has logged 26 consumer complaints and several Early Warning Reports (EWRs) that describe sudden, intermittent spikes in steering effort during normal driving.
Why the steering issue matters
Any abrupt increase in steering torque can compromise driver control, especially at highway speeds or when maneuvering around obstacles. While the defect does not completely disable steering, the sudden load can cause delayed reactions or over‑correction, raising the likelihood of a collision. ODI currently links two reported crashes to the steering anomaly, though no fatalities have been attributed to the fault so far.
Scope of the investigation
The NHTSA inquiry covers 43,752 CX‑90 units sold in the United States. Investigators will assess whether Mazda’s previous recall fully resolved the underlying mechanical friction or if a latent defect remains that could affect vehicle control in specific scenarios.
Potential outcomes for Mazda and owners
If the agency determines that the 2024 recall was insufficient, Mazda may be required to issue an additional recall with a more robust fix—potentially an upgraded gear assembly or a revised EPS software module. The CX‑90 is a key model in Mazda’s North‑American lineup, positioned as a large‑capacity SUV aimed at families and fleet buyers.
For owners, the immediate recommendation is to monitor steering feel closely. Should the wheel become unexpectedly heavy, or should you notice any loss of power assist, contact your Mazda dealer promptly. Keep records of any incidents and retain service documentation, as these may be requested during the investigation.
What’s next?
Mazda has said it will cooperate fully with the NHTSA investigation and continue to share data on the EPS system’s performance. The agency expects to release an interim report later this year, which will clarify whether further action—such as a supplemental recall—is warranted.
Stay tuned for updates, and if you own a 2024 CX‑90, schedule a service appointment if you experience any steering irregularities.
