Electric parking brake. The electric parking brake activated it self while driving in traffic. Heavy traffic situation 5 mph and the E. brake came on and stayed on. The vehicle did not move forward or backwards. Turn the engine off several times, put in parking, neutral etc etc. After 5 minutes of blocking traffic, I had to force the vehicle to the shoulder. Almost did not make it. Turn vehicle off and called the flat bed. While waiting 15-20 minutes later turn vehicle on and SURPRISE!!! It was fixed. MAGIC. The E brake was off and the vehicle was free.

While this was going on the E Brake light (red) was on, and Service Parking Brake light (amber) was flashing all the time. Dealer did an update to the system and is not sure if it will happened again. But this is the THIRD time this happened. Once at my house about six months ago, but it took about 1 minute and it fixed itself so I did not pay attention to it. The second time it happened to my wife at a shopping center but she left it in the lot and went back shopping and when it came out it was fixed.
