Steering Instability: The steering wheel would periodically veer to the right and left on its own without my input. This created an unsafe driving condition and required constant correction to maintain control of the vehicle. Blind Spot / Reverse Detection Malfunction: When shifting the vehicle into reverse, the dashboard display indicated that no vehicle was present. However, when visually checking my driver-side mirror, there was clearly a vehicle immediately adjacent to my car. The system failed to detect or warn of the nearby vehicle, creating a significant near missed accident and safety risk.
