You seem insistent on getting my comments. While the overall experience was pleasant enough and the personnel were all friendly and supportive, my problem was not resolved. The result of my recent visit is that the 4WD alert is still showing up. I was told that a $300+ diagnostic might find the problem (and my truck is out of warrantly). I originally presented the truck under warranty with this problem. Your staff could not find the problem. The second time I brought the truck in, you convinced me that a $145.00 dollar software upgrade would solve the problem. It did not. This third visit seems to portend a series of visits where I keep paying for additional diagnostics without a resolution. By the way, during the first visit, the problem presented itself during check-in; so I am not imagining the issue.
