ISSUE 1 – UNINTENDED DECELERATION (Power Train): While driving at highway speeds (60–80 mph) with foot off accelerator for approximately 5+ seconds while coasting, the vehicle unexpectedly executes a sharp, single downshift causing sudden unintended deceleration and an RPM spike. No warning lights illuminate. Documented on 11 occasions between May 20, 2026 and July 29, 2026; incidents occurred prior to May 2026 but were undocumented. Occurs most frequently decelerating off highway exit ramps but also during general highway coasting in Houston, TX. A passenger was present during multiple incidents. Trailing vehicles are not anticipating the sudden speed reduction, creating rear-end collision risk. ISSUE 2 – FALSE BLIND SPOT / REAR RADAR ALERTS (ADAS): The Blind Spot Monitoring and Rear Radar Sensor systems generate daily false alerts — both audible and visual — when no vehicles or objects are present. Triggers randomly across varying conditions. False alerts have caused multiple aborted lane changes that were otherwise safe to execute. ISSUE 3 – LANE KEEPING ASSISTANCE (ADAS): The LKA system applies forceful steering corrections during intentional, signal-indicated lane changes, including in areas without lane markings. Occurs at highway speeds during on/off-ramp transitions. Corrections have triggered reactive maneuvers by surrounding drivers in dense traffic, causing near-collision situations. Dealer service appointment scheduled August 6, 2026.

I own a 2026 Mazda CX-90 hybrid with approximately 13,000 miles. The vehicle began making a grinding noise while driving, which has progressively worsened over time. It has since developed a hard knocking noise accompanied by noticeable vibration when the vehicle shifts gears. This knocking occurs during normal in-town driving. I have taken the vehicle to the selling/authorized Mazda dealership on two occasions — June 2, 2026 and July 14, 2026. On both visits, the dealer was able to reproduce and confirm the noise and knocking. The dealer stated they are aware other customers have reported the same issue, but that Mazda considers the noise/knocking acceptable and declined to perform a repair. No warning lights or diagnostic trouble codes have appeared at any point; the only symptoms are audible and physical. The vehicle is under both factory warranty and a purchased service/maintenance agreement. It has only been inspected by the selling dealership; no inspection has been performed directly by Mazda North America, law enforcement, or an insurance representative. I am concerned about my safety and the safety of others because a worsening, unexplained drivetrain issue that produces hard knocking and vibration during routine driving suggests a mechanical fault that could progress to sudden failure, and the manufacturer has declined to investigate or repair it further despite the symptom escalating across two documented visits. The vehicle remains available for inspection upon request.

My car is literally stalling out on me. It started by sputtering when I put my foot on the gas a week or so ago. Then today It literally started just losing power while driving. It’s not throwing any codes but that’s super dangerous and this car is only a year old. I am extremely concerned for my safety.

RQ26002 · Momentary Increase In Steering Effort After Recall Remedy
Opened Jan 26, 2026 · No close date supplied
Status: open (inferred from source dates) · Steering; Steering:rack And Pinion
The Office of Defects Investigation (ODI) has received 26 complaints and several Early Warning Reporting (EWR) Field Reports alleging intermittent and brief increases in steering effort (described as “sticky steering”) during the drive cycle in model year (MY) 2024 CX-90 vehicles manufactured by Mazda North American Operations (Mazda) subject to Recall 24V2022. In each complaint, the vehicle had the recall remedy completed prior to the reported incident. Recall 24V022 addresses a sudden and unexpected change of steering effort while driving caused by excessive worm gear friction force. After receiving the recall 24V022 remedy, consumers report sudden increases of steering effort while driving. Sudden and unexpected change of steering effort while driving may increase the risk of a crash. ODI is opening this Recall Query (RQ) to assess the adequacy of the remedy for Recall 24V022 and to identify the cause(s) of the conditions leading to the post-remedy reports. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
