Vehicle has a rattle upon starting. Also the vehicle is shifting harshly and slipping. Sometimes the vehicle will stop accelerating in the middle of the road, or when accelerating from a stopped position. The RPMs will rise but the vehicle stops having power and the gear indicator moves up and down until it clicks back into a gear and the vehicle will go again. I have had the vehicle examined by a technician and have been told that it is the cam phasers, CDF drum/transmission, and torque converter. Ford will not honor any warranty or cover the cost of these repairs.
