One problem related to structure has been reported for the 1999 Ford Explorer Sport. The most recently reported issues are listed below.
I have a 1999 Ford Explorer Sport with a step bar that has completely rusted of the first year of purchase. After the winter of 2000 the bars has been rusting more and more there is nothing that I can do as a consumer. The dealership will not replace it under my warranty because they consider that wear and tear. This matter needs to be attended to as a safety issue. Stepping on a rusty bar that will give any time soon can not be good for anyone with little kids.
