HOW TO REPAIR THE AIR SUSPENSION

The system was 'rebuilt' 2 years ago and now it will not respond other than SYSTEM IS COOLING DOWN.
Is there a inexpensive fix and has FCA owned up that they screwed up?

The OEM air ride system is a closed system and it is filled with nitrogen from the factory. The issue comes about when it thinks the nitrogen is getting low, it has the ability to pull ambient air to ensure there is sufficient volume to maintain the required pressure in the system. If this happens, then there may be problems in the cold due to the moisture in the air freezing the system. The system is sealed and utilizes nitrogen. If it is frozen, water has been introduced to the sealed system and the only way to fix it is to find the leak, then evacuate the system and recharge.

There is a connection behind the passenger side rear wheel to recharge the system with nitrogen. If you're having issues with the system freezing or blowing fuses for the compressor, then have the system purged and refilled to ensure there is no air or moisture present.

Compressed (shop) air contains dirt and moisture, whereas the nitrogen as the system is filled at the factory - has much lower moisture content.

You have choices; a total air suspension delete, and replace the system completely with a conversion kit.

You can repair or rebuild the stock system, or contact FCA to see what they might recommend.
