On 1/10/18, I was on my way to work and received message "engine power reduced", the engine light came on and power was reduced to 25 mph. I brought the Terrain into a mechanic and he synchronized the gas pedal sensor and fuel sensor and the engine light went out. On 1/13/18, the same thing happened except I was on a highway and it was much more frightening. I brought the Terrain back to my mechanic and left the vehicle. I am now without a car for the weekend.
