My wife has a cold. She picked it up during several uncomfortable hours in the emergency room. Our driveway is on a bit of a slope. She stopped the car, put it in park (she thought), turned off the engine, and got out. Something in the dashboard compartment had blocked the shift lever and the car was actually in reverse. It started rolling backwards down the driveway. She grabbed it and tugged with all her might and actually succeeded in stopping it when it got to the street. She managed to prevent our car from rolling into our neighbor's parallel parked car immediately across from our driveway. She also managed to hurt her arm quite badly. X-rays and CAT scans and exposure to every sniffling, coughing person in the ER later, and we learned she was lucky and did not break any bones, just sprained her elbow and shoulder. Very very lucky that she didn't get knocked under the wheel by the still open door of the car! My question is this: Can automakers create a safety device to prevent this? If the engine is off and the car is not in park, and no driver is detected in the driver's seat, can they automatically apply the brake? There could be a button or switch to undo the brake for towing. It seems the technology to do this has been around for decades, but the X-ray tech, the ER admissions nurse, my wife's orthopedist, even the lady at our insurance company all had stories of similar happenings. How can such a safety device become standard?

When driving with adaptive cruise control engaged I have had multiple incidents where the forward collision warning and automatic emergency braking engages when there is no vehicle in front of me. Similarly, with adaptive cruise control engaged and approaching a red light, I have had multiple incidents where the cruise control does not sense the stopped cars and does not automatically engage the brakes

The issue is the steering colomn. There is a bolt that comes loose when driving on "irregular roads". my safety was at risk because if this bolt decided to come out i would not have control of the vehicle. I was told that the steering wheel would disconnect from the steering colomn or the steering wheel would completly detatch. The problem was confirmed and inspected by the Mazda dealership. No warning messages appeared on the dash, only notable symptom was an intense clunking sound coming from behind the steering wheel.

I am reporting a safety concern involving multiple loose windshield header bolts and cowl panel fasteners on my 2022 Mazda CX-9. The issue was discovered on 1/28/26 at approximately 44,000 miles. Several bolts securing the windshield header and cowl panel area were found loose. These components support parts located at the base of the windshield. Loose fasteners in this area raise concern about potential windshield instability, movement of the cowl panel, and possible detachment or structural compromise over time. This condition could create a safety risk, particularly at highway speeds, including driver distraction from vibration or noise, potential windshield instability, and possible failure of components mounted near the base of the windshield. The Mazda dealer is aware of this issue. I was informed that they have repaired at least 15 similar vehicles, including those associated with a Roman Service member, indicating a possible pattern. Despite this, Mazda did not cover the repair cost. Given that multiple bolts were improperly secured and that the dealer has seen numerous similar cases, this appears to be a potential manufacturing or assembly defect affecting multiple vehicles. I am requesting that NHTSA review this issue for possible investigation and recall consideration.
