“A persistent humming/whining noise occurs at highway speeds (around 60–70 mph). The noise has been present for more than two years and has continued through multiple major repairs. The sound appears to come from the drivetrain area and raises concerns about a potential driveline or mechanical failure at speed. The issue has been reproduced and confirmed by multiple authorized dealerships. The vehicle has undergone two rear differential replacements, a transfer‑case replacement, chassis ear testing, STAR engineering cases, and testing with OEM wheels and tires. …”
