Apr 24, 2026SteeringLane Departure

Sometimes when I’m driving the steering wheel just jerks to the left sometimes causing me to swerve into incoming traffic. It’s very scary. Luckily I’m holding tight to the steering wheel to keep myself from hitting someone.

Feb 25, 2026SteeringLane DepartureDriver assistance

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.
