UPDATE: Transmission Slipping: So obviously, very unhappy with the fact that my low mileage, almost $40,000 vehicle was in the shop AGAIN, this time for something pretty serious. I decided to write a letter to the dealership explaining my frustration and all of the concerns I've had and am currently having with this vehicle. Again, they initially told me they couldn't get my vehicle in until Aug 12, and I dropped it off on July 23. So I explained how I thought that was very unreasonable even though they have given me a loaner (after an argument) due to the fact that i'm wasting 3 weeks of my warranty while it just sits there. I got a call Friday around 2:30, saying the vehicle was done and ready for pick up. I asked what the problem was and they said that they drove it and sure enough, it was slipping under acceleration and had lost a decent amount of power. They said they took it back and reprogrammed it and that had fixed the issue. Sure enough, when I went to pick up the vehicle, it was running like normal and the transmission was no longer slipping. I have no idea what reprogrammed means and I did not realize I was driving a cell phone that needed updated or reprogrammed every 6 months. Regardless, I am happy with the outcome and I HOPE this is the last of my issues with this explorer. It sucks buying something for a decent amount of money with the idea that your paying for something that without question, should for the most part, be reliable and have very little issues. So we shall see... Thank you all for the responses. This one had a happy ending.
