POWER TRAIN,ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM — Filed 06/15/2026

Vehicle has experienced multiple electrical and mechanical failures at unusually low mileage. Purchased at 32,000 miles. At approximately 50,000 miles, the factory radio/infotainment system failed completely. Electrical systems were observed remaining active after the vehicle was powered off, suggesting an underlying electrical fault. At approximately 60,000 miles, the power steering rack and fuel pump both required full replacement and were confirmed and replaced by an authorized dealership. No warning lights appeared prior to these failures — components failed without any prior indication. At approximately 100,000 miles, the transmission began failing and exhibits the known torque converter shudder issue widely reported on this vehicle platform. The shudder was present prior to full transmission failure symptoms appearing. The pattern of premature failures across multiple unrelated systems — electrical, steering, fuel delivery, and transmission — suggests a broader manufacturing defect.
