NHTSA Complaint #11468924 — 2021 FORD BRONCO

About 1 hour into our trip the vehicle started to shutter while at highway speed, no warning lamps or notices were indicated when the shutter started and I assumed it was a road vibration. We came to a stop sign about 2-3 miles after the shutter was noticed and the vehicle stalled at the intersection and would not restart. At that point the check engine light, in dash notifications and Fordpass app notices indicated a serious mechanical malfunction. The vehicle needed to be put in neutral and pushed to the side of the road by me and my son to clear the intersection. Ford roadside assistance was contacted and a tow truck was dispatched to take the vehicle to the closest dealership. We sat at the side of the road for 2 hours waiting on the ford dispatched tow truck. The vehicle was towed to Ford of Clermonth. The Ford of Clermont, Florida service department ran diagnostics on the vehicle the next morning(12/06/21). The Ford service technician, following Ford's diagnostic directions, determined there was catastrophic engine failure and Ford immediately authorized an engine replacement. As per the attached service invoice the Ford Service technicians determined it was a valve failure that caused the engine failure.
