UPDATE: So I've been sitting at the dealership for over 5 hours.... And they're still working with Jeep technician through the "Star" network to diagnose the problem. To make matters worse they won't give me a loaner if they can't figure it out by days end... Am I wrong to request a loaner jeep so I can actually do something other than sit around at the dealership on my day off while they work on my 5 month old vehicle?
Did you mention the two solutions I posted for you? Sounds identical to my problem that I had.

Well its possible there is a failure, I would suggest reading your owners manual again. I beleive that the ride height will only be at NORMAL unless you are in ROCK or SAND mode. Not 100% sure on that but I do beleive that is indeed the case. In other words the jeep won't let you drive it around town and try to look bad a$$ unless its in the off road configuration...ie... ROCK or SAND... if it works in every other mode I doubt you have a "leak"...

No you are wrong. In auto mode it should be able to go up to OR2 as long as you are under 25 mph and up to OR1 under 50 mph.

Here's some Operation information from the service manual:

WARNING: All pressurized air suspension components contain high pressure air (up to 220 psig). Use extreme caution when inspecting for leaks. Wear safety goggles and adequate protective clothing when inspecting or servicing the air suspension system. A sudden release of air under this amount of pressure can cause possible serious or fatal injury.

WARNING: Support the vehicle by supplemental means before performing any work on the air suspension system to prevent the vehicle from changing height. Before any given component is to be serviced it must be deflated. Servicing the air suspension system without supplemental support, or with pressure in the specific component, can cause possible serious or fatal injury.

CAUTION: When removing an air line from a component and the air line is to be reused, do not remove the 90° fitting or the brass fitting from the air line. If either is removed, the air line must be replaced. New components have air line fittings attached; however if the original air line is used the original fitting must also be used. Do not remove protective caps or plugs from air lines or components until ready to install the air line to prevent moisture or dirt intrusion. All air line fittings must be hand started to avoid cross threading.

NOTE: The air suspension system will auto-disable when lifted on a frame hoist, or when jacking one corner of the vehicle. The air suspension may attempt to change height slightly prior to switching to auto-disable. A manual disable is also available by pressing the "Up" and "Down" switches of the terrain select switch simultaneously for more that 5 seconds. The air suspension system will return to normal operation when the vehicle speed reaches 25 kph (15 mph).

NOTE: The air suspension system will not lower if any of the doors or liftgate is open (normal operation) or the engine is not running. Doors and liftgate status are ignored when using a scan tool.

NOTE: When the Air Suspension Control Module (ASCM) or any height sensor is replaced the ASCM will need to be initialized using a scan tool. Refer to the appropriate installation procedure for specific instructions.

General Information
The air suspension system is designed to raise and lower the vehicle height as required depending on driver request using the terrain select switch, or automatically with the terrain select switch in the Auto position. There is an Air Suspension Control Module (ASCM) located under the driver's seat which contains the logic and controls for the system. Multiple modules work together to increase vehicle stability and traction along with vehicle ride height. The ASCM uses several Controller Area Network (CAN) data bus systems for inputs and outputs of the information necessary for the different systems to operate. The use of a scan tool is necessary for diagnostics, and replacement of any pressurized components. Height sensors on each corner of the vehicle monitor the vehicle height. The front of the vehicle is raised/lowered with two air suspension spring and shock assemblies, and the rear uses two air suspension springs.

The air suspension is a closed type system that does not draw in fresh air during vehicle lifting or leveling. Instead, it moves pressurized air back and forth between an air suspension reservoir and the four air springs as required to raise or lower a specific corner of the vehicle. The air suspension compressor assembly includes an air suspension valve block, controlled by the ASCM. The valve block isolates and actuates the raising and lowering of each pressurized component using individual air lines for the air springs and reservoir. The air suspension compressor does have a filtered air suspension hose assembly for adding air volume if a component of the system loses its air pressure and is replaced. The compressor is not intended to replenish the entire systems air volume. There is a procedure for complete system fill using an external source if it is necessary; however, this should only be necessary if the air suspension compressor or air compressor valve block is replaced.

Refilling the System
If the air suspension system is fully depleted of air it can be refilled using a scan tool and Air Suspension Refill Tool - 10247 which is used with a nitrogen supply tank (can be acquired at a local gas supplier). The nitrogen must be Purity Class 5 (99.999% pure). The size and volume of the nitrogen supply tank will determine how many air suspension systems can be filled.

Changing Ride Height

Using the terrain select switch, ride height can only be changed while the air suspension system is in normal operating conditions. To change the ride height using the terrain select switch. Air suspension system normal operating conditions are as follows:
Scan tool disconnected
All doors closed
Liftgate closed
Engine running
Minimum battery voltage greater than 10.5 volts

Using a scan tool, ride height can be changed regardless of the engine state (running or not), doors or liftgate state (open or closed). The only condition necessary is that battery voltage must be greater than 10.5 volts.

Ride Heights for Suspension Measurements or Adjustments
When checking or performing an alignment the air suspension system must be in the manually selected "Sport" position of the terrain select switch or the Aero mode if using a scan tool. When measuring curb height, the air suspension system must be in the manually selected "Auto" position of the terrain select switch, or the Normal Ride Height (NRH) mode if using a scan tool.

Manual Control
A terrain select switch is located on the console for driver control of the system. When the driver presses the terrain select switch to manually (two RH buttons) raise or lower the vehicle height the Electronic Vehicle Information Center (EVIC) displays a vehicle "up" or "down" icon and a LED indicator on the switch changes position. The EVIC displays the current position of the vehicle when it is achieved. When lowering the vehicle, the front is always first to move. When raising the vehicle, the rear is always the first to move. When the ASCM receives a command to change the vehicle more than one ride height position the action is performed in multiple steps. If request to change by two positions the rear will raise one position, then the front will raise one position, the rear again raises one position, then the front will raise to the final position. If requested to lower more than one position the same steps happen, EXCEPT the front moves first. This multi-step motion controls the angle the headlights are projected by controlling the pitch of the vehicle, keeping them from going above their normal projection plane.

There are five predetermined manual height settings; Normal Ride Height (NRH), two above and two below NRH. The predetermined vehicle heights (above or below NRH) are as follows:

Off-Road 2 (OR2), + 65 mm (2.6 in.) (Except if equipped with AMS + 56 mm [2.2 in.])
Off-Road 1 (OR1), + 33 mm (1.3 in.) (Except if equipped with AMS + 28 mm [1.1 in.])
Aero Mode, - 15 mm (0.59 in.)
Park Mode, - 40 mm (1.57 in.)

Automatic Control
There are five choices for automatic control using the center rotating knob of the terrain select switch. The choices are Auto, Sport, Snow, Sand/Mud, and Rock. When the driver chooses an automatic setting multiple systems are affected for the best vehicle performance. Some of the modules whose systems use these settings are:

Air Suspension Control Module (ASCM)
Antilock Brake Module (ABS)
Automatic Headlamp Leveling Module (AHLM)
Drivetrain Control Module (DTCM)
Powertrain Control Module (PCM)
Steering Control Module (SCM)
The basics of how the different automatic settings effect the systems are listed below:

Auto - When in 4WD High range the vehicle height is at NRH. The vehicle systems are set to normal performance settings. Combines optimal traction with seamless steering feel. When in 4WD Low range the vehicle height adjusts to 38 mm (1.49 in.) above NRH, the transfer case locks, and the transmission shifting adjusts to off road shifting.
Sport - When in 4WD High range the vehicle height adjusts to 15 mm (0.59 in.) below NRH. Electronic Stability Control (ESC) and traction control tuning thresholds are raised, and the Antilock Brake Control (ABS) allows less wheel slip, all to allow more driver control. Also the transmission shifting adjusts to a higher performance shifting. Not available in 4WD Low range.
Snow - When in 4WD High range the vehicle height is at NRH. Traction control is adjusted to allow less wheel slip, and initial vehicle launch will be in second gear. When in 4WD Low range the vehicle height adjusts to 33 mm (1.3 in.) above NRH, the transfer case locks, the transmission shifting and ABS adjusts to off road settings.
Sand/Mud - When in 4WD High range the vehicle height adjusts to 38 mm (1.49 in.) above NRH. Electronic Stability Control (ESC) tuning threshold is raised, and the ABS allows less wheel slip to allow more driver control. When in 4WD Low range the vehicle height adjusts to 38 mm (1.49 in.) above NRH. The transfer case and the Electronic Limited Slip Differential (ELSD) locks, the transmission shifting and ABS adjusts to off road settings.
Rock - Not available in 4WD High range. When in 4WD Low range the vehicle height adjusts to 65 mm (2.6 in.) above NRH. The transfer case and the ELSD locks, the transmission shifting and ABS adjusts to off road settings, and hill descent control is activated for steep downhill control.
