Car will not accelerate. Error code P211800. Engine control system. Throttle control. Temp outside was 19degrees F. Check engine light is on.

The throttle body froze up and the Van went into "limp mode". I was driving on a semi-busy road and I could not go above 10mph. It would not let me shift either. Like it was not getting any gas to let me accelerate. The check engine light was on, I used a scan reader and the code came as P2118. Also when it went to the dealership the check engine light was still on. It was inspected by the dealership, but only deleted it and it was given back to us. Yes, the first symptom was the idle was rough and the exhaust was making a deep noise. *Dealership wrote that it had high rpms*, which I never said that to them, I told them( dealership) that it was low rpms with the rough idle. I had it idle for 5 minutes so it could warm up since it was 15 degrees that night. This issue is not safe because I could get hit from behind because the van can not go faster or drive at the marked speed limit on city/highway roads. Also, having issues like this is not safe for my kids or other passengers in the Carnival. The dealership said it is from condensation getting into the throttle body. But I have never had this issue with any other car/truck I have owned.

Will not accelerate over 10 Mph in cold temp even after warming up vehicle. Will lose acceleration at a intersection and dangerous while taking a left turn. Check engine light goes on. Throttle bottle issue. Believe it is moisture/water in the throttle body causing it to freeze in colder temps. NEEDS TO BE RECALLED. Many many other Kia Carnivals having same issue. Model is brand new and should not be having these issues. FAMILY CAR.
