When I started the car an alert came on the said the door there was a driver door contact switch error. When I was trying to back up the emergency brake came on. The door was closed. There was an electric parking break error. Also a start stop error. When trying to go forward the parking brake kept coming on. I was going 10 mph and the e brake engaged and would not let me out unless I turned off the car and turned it back on. When I brought it to the dealership they ran tests on it and they said it was the door wiring harness. There is problem with it and it is not safe to drive. When driving around corners it also has a tendency to want to depart you from the lane. It will try to kick you out of the lane even if you are in the middle of the lane. It has done this around corners and when driving straight. It caused my sister to be driven off the road. This has been brought to the dealerships attention and they found a problem with the lane departure and told me that they could fix it and then they came right back and told me that there was nothing wrong with the car.
