“Have had 2 of these 2004 Ford sport trac trucks. One which was flipped onto my driver side and totaled in an accident where I was hit doing 25mph down a back road whith a stop sign intersection, no airbags went off the only thing that saved me was my seat belt from worse injures. My current truck which has been well maintained and I still have all receipts for over 5000 worth of work done, recently with over a quarter tank of gas turning left will cut out and die completely in traffic which has almost cause me to be hit a couple times with my child in the car. …”

“At 70,000 miles, my truck is starting to slip when shift from 2nd to 3rd. I did some research on the issue and found that this and other major issues with the automatic transmission on my sport trac were very common. I purchased the vehicle new in may of 2004. Within a year, I received a letter stating that Ford needed to add some type of fluid to the transmission. When I took my truck in for this, the mechanic mentioned that this was to prevent a major issue with the transmission and also prevent failure due to a mistake at the plant. …”

“2004 Ford explorer, sport trac xlt. Only have 37,871 miles on this truck and already having problems with transmission. Transmission slips in 2ed gear and take about 3 to 4 seconds for reverse to engage. Ford dealer charged me 159.00 dollars to change trans fluids. I told them that the fluid was dark and smells like metal. I call them back up telling them it didn't fix the problem. I talked to another service person and he stated that if there was a metal smell there is something else wrong. And will cost 75.00 to check it out . Thank you Ford for a wasted fluid change.”

“The truck's transmission slips going from first to second gear. This was a noticeable problem around 35k miles, and has continued to happen infrequently. Ford sent a letter, january 2005, stating that the transmission fluid used at the assembly plant needed to be replaced because, that over time, it could cause delayed/harsh engagements. When I took the vehicle in for the fluid replacement (42k miles approx), I mentioned this problem to the service employee. He said that this would probably fix the problem, and that I should drive it for awhile to see if the problem corrects itself. …”

NHTSA complaint #10138943, filed 2005-10, 38,000 miles

“I purchased a 2004 Ford explorer sport tracker 11 monthes ago. The first incident was the shocks towers. So, I thought. When I brought it into the dealership, they said it wasn't the shock towers but the sway bar. This occurred around september 2004.. Than I brought it into the dealership again because the transmission was slipping. I was told the transmission was brought into the shop. I only have 23,000 miles on the truck. When I bought this truck it had 23 miles on it when it brought it. I have put alot of highway miles on it. But the transmission should not have need to be rebuilt.”
