2012 mustang gt electric steering issue and service advancetrac msg

I have been having this steering problem for about 2 weeks now. When i first start the car and try to back out my driveway the steering wheel starts to lock up and the service advancetrac msg comes on. Once I get going up to speed the steering is back to normal and msg stays on. So I have been doing a lot of research on this issues and it seems to be common yet no real solution other than a big headache and horror stories with dealerships. So after my own horror story with a ford service center (which they wanted to change out my steering rack ) I decided to pass up the $2000 giveaway and pick at it myself. What I found was a $20 fix. I decided to look at the electrical wiring since it was an intermittent problem. I thought maybe a loose wire or so. I took apart the positive side terminal and cleaned it very well individually then put it back together. Next I got under the car and took off the oil change cover to expose the steering rack. The steering module just so happens to be right under the oil filter. I decided to unplug the steering module connectors and found them to be really oily and dirty inside. I cleaned them very well and also the connector on the module side. Make sure the battery is disconnected by the way since i believe it has direct power to this connector. Onced they were clean and dry and put some dielectric grease and plug them back up. Took the stang on a test drive and so far so good. So it seems like when the oil filter is being removed , residual oil is getting into this connectors. I hope this helps at least one person. If you have this similar problem might want to check this out before taking it into a dealership.

ps $20 was on electrical cleaner and dielectric grease and a small steel brush

Great information. After a month or so, please update the thread so that we'll know if this actually fixed the problem.

Thanks for letting us know about that. I noticed that those connectors tend to get some oil on them if you are not careful when changing the filter. I think I will cover them during oil changes going forward.

I suspect simply unplugging the connectors and re-plugging them improved conductivity since oil shouldn't cause any conductivity problem?? After all dielectric grease is just more (thick) oil!!

Glad it's working for ya.....

If oil can get in there, that means other corrosion inducing stuff can as well.

Nice find orlandovls2!!
