I purchased my 2011 Explorer is April. Since then, I have had it to the dealer 5 times for repair. I get the power steering assist warning and the terrain system warning lights.. Signal lights will not work, and it's nearly impossible to steer. They have replaced the rack and pinion twice, updated the software, and the other two times the codes were reset. The last rack and pinion only lasted 3 days. The code is showing that it is bad again, but the service dept. doesn't want to change it. They suggested that I replace the tie rod ends, but when I ask if they were bad, they told me that they were not. I was told that they were able to align the front end without any problem, so the tie rod ends are not at fault. They also tried to say the battery was going bad, but I had it checked and it was fine also. The strange thing is, the steering has failed in the same curve (right hand) three times. I mentioned this but they didn't really say anything about it. It's very frustrating to think that I still owe on this vehicle for four years. I'm afraid to drive it anywhere, especially with the children. Ford customer service has worked with me so far. The dealer didn't want to replace the rack the second time, but once I called Ford, they did. I'm not sure what the next step is, unless I take it to another dealer and let them check it.
