Since mine is new,I thought I'd jump on the interstate before I get into some back roads. Interstate travel was fantastic, as were the back roads...playing around with the paddle shifters. On the way back while traveling the interstate with almost no traffic at all (I was messing around with the nav) suddenly I hear a strange sound, I looked at the dash and there was a message that said "time for a brake". I've never seen anything like that before on any car. At that point I was traveling for maybe 100 miles and not crossing any lines. I'm thinking perhaps I may have been oscillating back and forth in my lane since I was messing around with the nav. Has anybody else seen that message?
