The vehicle currently has fewer than 4,000 miles on the odometer. Since early in my ownership, I have experienced a persistent and recurring squealing noise that occurs specifically when releasing the brake pedal after a short stop, and when transitioning from braking to acceleration. This is not an intermittent or weather/humidity-related issue. The noise has been consistent and ongoing throughout my ownership and has not resolved on its own--I was thinking it might since new cars take some time to adjust. At under 4,000 miles, brake components on this vehicle should be essentially new. Brake pads are engineered to last between 30,000 and 70,000 miles under normal driving conditions. A persistent brake noise at this mileage cannot reasonably be attributed to normal wear and tear and is indicative of a manufacturing defect, defective OEM brake pad compound, or a sticking/dragging brake caliper that fails to fully release after braking. I note that NHTSA has previously investigated Hyundai Sonata brake behavior, including a technical bulletin concerning rear brake pads remaining in contact with rotors after a diagnostic self-check cycle, causing a dragging condition in the next drive cycle. My symptoms are consistent with this type of brake drag behavior. Multiple Hyundai Sonata owners have documented the same persistent squeal-on-release pattern on Hyundai owner forums, with some reporting the issue beginning within the first year of new vehicle ownership and dealers being unable to diagnose or resolve it. I have formally reported this issue to Hyundai Motor America Consumer Affairs prior to filing this complaint and have requested warranty coverage.  I am filing this complaint to create an official federal record of this defect and to contribute to any pattern investigation NHTSA may conduct on 2025 Hyundai Sonata brake systems.","products":[{"type":"Vehicle","productYear":"2025","productMake":"HYUNDAI","productModel":"SONATA","manufacturer":"Hyundai Motor America"}]}]}
