“On six different occassions my vehicle has stalled out while reaching speeds of up to 50mph. I have taken it back to the dealership on 3 separate occasions to be told there is nothing mechanically wrong with the vehicle. On 8/25/3020 it stalled again and caused me to be rear ended. I am terrified to operate this vehicle on public road ways now.”
