My car drove fine and then I stopped at a red light at a busy intersection when my traction control and check engine light came on and the engine power reduced came across the dashboard. The lights, wipers, radio and engine was still running but when pressing on the gas pedal the car would not accelerate. I had to wave people to go around me put it in park and shut it down for 30 seconds. When I turned it on again I had to put it in reverse and keep pushing the gas pedal to get out of the intersection then I put it in drive and just kept pressing the gas pedal and inched my way into a parking space. After shutting it off and parking it for 2-3 minutes I turned it on the check engine light stayed on but the car drove like normal to get me to the dealership. I got this car in may of 2013 and the first time it happened was Feb 2014 pretty cold temps and now April 2015 about 56 degrees F outside. Both times the dealer replaced the throttle body and performed idle relearn procedure. I don't have time or money to replace this part every year. I loved the size, gas mileage, design and comfort of this vehicle, however I won't be buying another General Motors vehicle again. I always owned GM vehicles but not anymore I simply don't feel safe.

Leaving a stop sign onto three lane road going down a hill, when the car had no acceleration, I put on flashers and coasted to curb, had to call wrecker and be towed to dealer, said it was a throttle body sensor, that is sensitive to cold weather,2 dealers said the same thing. New part was ordered, but I don't feel safe in our cold weather if this happens on highway and it stops I am so afraid I will be run over by traffic moving at the speed limit and my Encore just stops. Feel my new part is not the fix for this safety issue, they say they can't say it won't happen again. Also read someone in N.D. was having same issue. Hope you can look into this.
