Vehicle experienced ongoing safety-related driver assistance system failures beginning at delivery. The vehicle initially could not be delivered due to unresolved windshield and sensor concerns affecting driver assistance features. After delivery, the vehicle continued experiencing intermittent failures involving adaptive cruise control, lane assist, cameras, and related driver assistance systems. Warning messages remained active and the vehicle was repeatedly returned for repair. Multiple repair attempts were performed over a period exceeding 30 days, including windshield replacement, calibration attempts, and outside vendor involvement. The dealership later advised that an improper windshield/calibration issue was responsible for the failures. Because these systems intermittently malfunctioned, I lost confidence in the vehicle’s safety and reliability, especially during highway driving where adaptive cruise and lane assistance systems are intended to function safely.
