Ford explorer

I purchased a Ford Explorer 2004 model 6 manths ago and from day one I had problems. The car was equiped with everything I wished for and very comfortable. However, the first indication of trouble was when I drove it out of the yard the "Service required" indicator came on and the car ran rough.
The explorer is equipped with a systems check screen and it showed that the oil efficiency was just 47% even though it had been just serviced. I went back to the dealer and queried if the service had in fact been done. After 2 hours of investigation they handed back the car saying the faults had been fixed. After driving just 10km the service light came back on.
To cut the story short I had the car in to the dealer 5 times which totalled 35 days. Between each time in for fixing I found extreme diff whine, clunk when reversing out of a parking bay like I had run over something, stalling at low speed with loss of steering and brakes, sluggish acceleration, car rolling when handbrake and being placed in Park, shudder when taking off.
In the end I demanded a refund and to the dealers credit they also conceded defeat and provided me with a replacement vehicle. Definitely not a Ford
