Transmission failed on 2019 F 150 4x4 after 146, 000 miles. The guidelines, according to our VIN number are to service closed transmission at 150,000 miles. Although we had the vehicle serviced regularly and were told the transmission would be serviced at 150,00, it went out anyway. We were stuck with an 8,100.00 bill through no fault of our own. We never used the truck for towing, rocky terrain or anything that would be taxing. We drove it for errands, daily use etc. Ford corporate refused to help with any of the expenses or accept any responsibility for an obviously defective transmission. Before purchasing the Ford, we owned a 2010 Toyota Tundra. We got it serviced regulary. We put 346,000 miles on the Tundra and it was still running like new. We ended up giving the Truck to our son. Ironically, we decided to buy a Ford next time because we believed that American made was better and we wanted to support an American company. So much for the confidence and support!
