I took a couple of co-workers to lunch today, to show of the new ride of course, and upon starting the car I noticed a warning saying that the driver assistance features were not working. I didn't have autopilot, cruise control, lane lines, speed limit signs, etc. The message said to call service. I decided not to worry about it and upon leaving the restaurant the car operated fine. Then on my way home from the office I got the same error. I called service and the tech on the phone had me stop in a parking lot and reset the "cpu"? (pressing both scroll wheels at the same time for 10 seconds) This didn't work so he said he would download some logs and call me back. A few hours later I got a call back and was asked to do a "power down" of the car. When I did this the driver controls came back. I've gone on 3 more rides since and all is well. My question - has anyone else had this happen? Should I be worried this is a concern moving forward? Any idea what the "fix" did? Thanks in advance! I am making my first short roadtrip tomorrow and I hope I have autopilot!
