Just got a 2011 Expedition Limited 4x4 and already having rear air suspension issues at 40K miles. Noticed something wasn't quite right and later that day the "check air suspension" indicator came on. Next time I started vehicle indicator was gone so I took into dealership and they couldn't find anything wrong. Next day I hauled my ATV to my hunting camp via trailer and while slogging through deep water in 4 low my rear suspension gives out completely. Unreal! Unhook the trailer and it goes back up. Hook up the empty trailer and it goes back down.
Drive home without trailer and it stays up for 2 hour interstate drive.

Is there a simple fix like a sensor or something I could change myself? I see a lot of folks on here changing out the air suspension but on older vehicles.

Any help would be mucho appreciated.

Hi Smoke,

Even though you sound like a DIY kind of person, you can always stop by your dealership so they can help. If you need any additional assistance, just let me know.
