There could be a couple of problems, first and easiest is the rear height sensor became disconnected from its mount. This is common because the sponsor clips on by a kinda weak spring and can be easily disconnected.also where the sensor mounts is a small round metal ball that screws onto frame and rear suspension, the balls after time wear to the point that the sensor spring cannot hold on.there's also an adjustment on the lower mount, if you move it up the vehicle will lower....then you could have a concern with the air compressor vent not allowing it to vent down to ride height. Or the vent solenoid on top of each bag stuck also not allowing it to vent..to ck it yourself, go for a short ride around the block and when you come back park on a level surface, shut off car, exit and close door....listen for an auditable click in the rear, and front left corner of car and watch the distance between rite and wheel lip, see if it drops. If it does I would be leaning towards the simple adjustment...also check thr front ride height on level surface, if you have a suspension problem on 1side of the car and it sits lower,it will throw off rear ride height. ...
there is a ride hieght sensor on rear lower control arms creck for damage and connection.over load rear suspention,4/5 people on back bumper with key on see if pumps up.also check fuses.try jumping compress to test compressor.worst case replace struts and use coil springs,eliminating air ride issues.
Sounds like your air ride suspension is either leaking air in the air bags, air lines,etc, or the compressor is not working. If your truck is still under warranty take it to the dealership to get it fixed or with a good mechanic. If it is an air bag or the compressor start checking online for any good, cheap parts because parts for this SUV run expensive.
Sometimes you can trick the module by opening all the doors,turning on the air ride switch and starting the car. Let it run for aboout 5 minutes.That should straighten out your ride. Let me know if you need more assistance
On this model vehicle the rear shockers should have air bags to keep car at normal ride height, when load changes. The air bag can sometimes become caught between inner and outer tubes of shocker when car is raised and lowered quickly. You will need to jack car up from tow hitch or frame to lower rear axle, this will unfold air bag, slowly lower car, with ignition on, this will make sure air compressor is filling air bags as they take the load. Hope this is helpful, MMP
