The vehicle’s Start/Stop system began displaying warning messages and malfunctioning prior to the expiration of the factory warranty. The issue first appeared before 50,000 miles and reappeared at 49,997 miles, when a warning was displayed on the dashboard. The vehicle was taken to an authorized dealer for inspection. A diagnostic review confirmed the need to replace the Start/Stop auxiliary battery and repair the Park Assist system. A diagnostic fee was charged, and both system failures were documented. The Start/Stop system’s failure raises a potential safety concern because the vehicle may not reliably restart after automatically stopping at intersections or in traffic. This could lead to dangerous situations if the vehicle stalls unexpectedly or fails to re-engage power at a critical moment. Although the issue has not caused a crash or injury, it introduces unpredictable behavior that could compromise safe operation. The Park Assist system also failed, triggering system warnings and disabling parking assistance features. If a driver is relying on these systems during low-speed maneuvers, a sudden or silent failure may increase the risk of collision with objects, pedestrians, or other vehicles. The dealership confirmed the problem through inspection and diagnostic testing. The manufacturer was contacted and declined to cover the repairs under warranty, despite the vehicle being within the mileage limit when the issue was first documented and presented for service.
