When it's cold and you start the vehicle I get a message reduced engine power. You have to immediately shut it off. Som etimes when you are driving down the road and it is warmed up it will do this and you have to find a safe place to pull over because if you try to give it gas it won't go anyways. I think it is a safety hazard because it can happen when you are going 70 mph on the interstate and cars are right on your ass. Luckily I wasn't on the interstate but I was on a highway going 60mph when it happened.
