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.

When starting the vehicle, or after awhile when you are driving the vehicle it will come up and read reduced engine power then you have to stop because it will not let you accelerate the gas pedal. Sometimes when you turn it off and restart it, it will be fine and sometimes you have to wait about 10 minutes then restart. It doesn't matter if you are on a side street or on the highway, it just randomly does this.

The main wiring harness loom that runs across the transmission and under the air box, was rubbing the transmission and wore thru 4 of the wires causing the engine to shut down.
