Hello all. I found this thread after experiencing the same problems with my Wife's 2012 Explorer that many of you were discussing on here.
I was driving at a Slow speed in parking lot, bells and whistles on dashboard went on and I lost all power steering. Which in reality, is the same as losing all steering. It was almost impossible to drive. After muscling the truck back home with my 18 month old in the back I called my wife to let her know what happened. She chooses then to tell me it's happened to her twice before and restarting the truck fixes the problem. (Wish I knew that before the workout I got driving it back home). So after seeing these posts, I call the dealer to make an appt .......
True story, as I pull into the dealers lot it happens again!! Perfect! Left it running, brought service writer outside so he could confirm the problem exists. He acts dumbfounded but I could clearly tell he knew exactly what it was. I made sure to tell him I researched this problem online (Thanks to you guys/gals) and that I know it's the steering rack that's causing the problem. (They love hearing that haha).
So he takes the truck in and I await the call. Sure enough, he calls me and says they looked into it and its definitely the steering rack that needs replacing. Before I can ask how long it will take, he starts asking about some scuff marks on the wheel and if we've ever hit a curb with the truck because that would cause this problem. Hahahah.
After literally laughing at him on the phone I explained to him that I'm well aware that its been an ongoing problem with the 11,12 Explorers and it not from rubbing a curb while parking. He then pulls the old "Ok, let me go talk to my manager" routine. He gets back on the phone a minute later and says "Ok, we're going to do you a solid because you're a good customer and replace the steering rack for free". Hahahaha I couldn't believe the nerve of this guy.
Anyway, I explained to him that he's not doing it because I'm a good customer, btw this is the first truck we've purchased there lol. He's doing it because its a defect and is covered under the warranty. Brought the truck in Tuesday, it was ready today. (Friday). So far so good. Ill update on whether or not it happens again. Interesting side note.. When I picked up the truck I asked "Is this the first explorer you've had come in with this problem?" He replied "No, this is like my fourth". UGH!!! Yet he still tried to play dumb when I initially brought it in!
Some advise: When it happens, take a picture of the dashboard when those messages pop up. Also, DO NOT let them accuse you of doing anything to cause the problem. They know damn well 99% of cars on the road have at least a scuff or two on the wheels. And let them know you've done your own research on the problem. The minute I mentioned this sight and the info on here his tone changed immediately. Good Luck.
PS: I absolutely love this truck. I hope it's fixed for good.
