2020 Alfa Romeo Giulia Tires & Wheels Problems

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. The noise remains after all repairs. The manufacturer’s Area Representative test‑drove the vehicle and verified the noise. Despite this, the manufacturer has stated that no further repairs will be approved, and the vehicle was returned with the defect still present. The vehicle has been out of service for more than 100 days for attempts to diagnose and repair this issue. The unresolved noise at highway speeds creates a safety concern because it may indicate an underlying drivetrain problem that could worsen or fail while driving. There were no warning lights or messages. The only symptom is the persistent noise at highway speeds.
