NHTSA complaint #11642894, filed 2025-02“This issue is connected with the 6.7L diesel engine. When sitting and idling it starts to idle really fast and the exhaust has an odor and strong fumes. It did not use to do this. I took to my Ford dealership and they say it's normal and there is nothing wrong. I have talked with other people that own the Ford diesel and they have experienced the same issue and been told the same thing by their dealership. No warnings or anything come up when the vehicle does this. If you enter the vehicle and touch the brake or accelerator it will then idle back down.”
