I've posted here a few times about the whine my Aviator produces at
10-15MPH and again around 40. The dealer had replaced the differential and then Ford declared that this was normal and no further attempt would be made to address the issue and my only recourse was arbitration so I started on the process.During this time my power steering started making weird vibration at parking lot speeds. Unfortunately intermittent and not reproducible easily.
At my 10,000 interval I took the vehicle in to another dealer and mentioned my problems. Their tech said it was a trans problem and they got permission to replace it. Unfortunately, still had the whine.
The arbitration board decided in my favor and Ford has to refund me the full price of the vehicle (after paying off the loan first of course).
Now I'll go buy my second choice -- an Acura MDX. Not as powerful of an engine, but at least it'll be a quality vehicle...
