I floored it out of a red light last night going up a hill. Traction control had to engage a bit. All of a sudden, around 40 mph, the car says that I need to pull over because it needs service. Instead of pulling 320 kW, I was suddenly pulling more like 30 kW, (not enough to get me up the hill at 40 mph). I move to the right lane, and move into the shoulder while all the cars from the light are passing me. After 15 seconds or so, the warning goes away, and the car is like normal again. Any thoughts?
