The 2025 Nissan Sentra lost control in the steering wheel or driveshaft while driving down hill. The vehicle lost power lost steering and crashed. The vehicle stated "malfunction " when the crash occured. There was a leaking fluid coming from the front left underside of the vehicle after the crash when it became undrivable due to loss of power and loss of driveshaft control. I felt unsafe with the way the vehicle was shuddering and jerking every right turn I made in the vehicle days prior to it being in a crash.
