One problem related to noises during shifting has been reported for the 1999 Ford Explorer. The most recently reported issues are listed below.
In the 19 months that I have had my Ford explore, it has had 3 recalls. About 4 mos ago I noticed a loud noise that seem to be coming from up underneat the car. You could hear it when at a stopped position but still in drive. I had the dealership check for it twice and they said they couldn't find anything. About 6 weeks ago I noticed a slight hestitation when on the highway when accelerating and it seemed to do it more over the last 2 weeks. July 2nd, my family was traveling home from new york and a noise began that could have been mistaken for something dragging underneath the car. We lost all acceleration, coasted off an exit, and the gears were useless and grinded when we tried to shift to park. The emergency brake was the only thing holding us there. I am still waiting for results from the dealership on the problem, but its definetely transmission related. I now fear for the safety of me and my 2 children in that vehicle. It seems like an accident waiting to happen. Thank you for your time.
