Example complaints
Other or unknown: “Last night, after we returned home, my wife removed a cup from our vehicle's cup holder. Shortly thereafter, an extremely loud sound of static began to be heard, emanating from the car's speaker system. Regardless of what we did the sound would not turn off, and remained ongoing for a period of about an hour. Nothing happened when we turned the speaker volume down, or turned the car on or off. It was not only loud, but also quite scary. We had the car towed to the dealership, but they indicated that they could find nothing wrong. …”
