Error: drive system. Please visit workshop

Whilst browsing the forums for this error, I realized that it is quite common. The funny part is I was just going into the motorway, and the car try to go into limp mode while displaying error message "Error: drive system. Please visit workshop". Instinctively, as there were cars behind me I very quickly put the car into S mode and continued driving. Interestingly couple of seconds later, the error message disappeared and the car continued to work normally.

I really started to feel vulnerable with this car. Will these weird error messages ever stop?

How's the car automatically connects to the service station and transmits the error message, I expect them to call in a couple of days I guess.

From the forums that I've read, it generally seems like a bug. I'm just wondering if anyone really did have anything with drive system.

Ps. From time to time, whilst driving it slow speed, I do feel like the transmission is slipping while changing gears. I just wonder if it's related to that.
