NHTSA Complaint #11705760 — 2021 FORD EXPEDITION

During highway operation, vehicle transmission makes very loud and angry sound and then loses ability to move , almost caused us to get hit at an intersection. Vehicle often jumps violently when shifting to reverse, and often loses propulsion when going uphill and shifting. No issues have been identified by mechanics but I have found several forums on line with drivers reporting similar occurrences. This is very dangerous and if not addressed will result in loss of life. We purchased this vehicle certified by the dealer with 92000 miles on it and it began doing this less than a week after purchase. We took it in for recall work and reported it and they said nothing was wrong with it. Manufacturer failure to rectify this very common problem is going to cause may citizens to be injured or killed.
