Example complaints

“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. …”
NHTSA complaint #11448472, filed 2022-01“When traveling on the highway, the vehicle would not shift into a higher gear limiting the control of the vehicle to accelerate to the flow of traffic. The transmission would not shift for approximately 1/4 of a mile and was stuck at a max speed of ~35 mph and it would not accelerate. This loss of control almost caused an accident and put my family and self at extreme risk. …”
NHTSA complaint #11680096, filed 2025-08“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.”
