The drivers side door opened while on the highway going 60-65. All doors were properly closed upon departure, and the door randomly opened. The doors were locked, so it stayed partially latched but ajar with the open door light suddenly coming on. It was a safety issue because it terrified me and I had to quickly pull over to close it/ assess what just happened. I will take the car to the dealership ASAP to report and have the latches inspected.
