“AWD indicator states off while driving at times without warning. Also leaking sludge. Now need to replace PTU and FORD AWD vehicles are known for this issue... Needs to be recalled as system can fail and explode.. This is supposed last the lifetime of the vehicle and is not set up for maintenance causing the system to fail. I am replacing with a unit that can be serviced every 30K miles. This is a safety issue.”
