Electronic air suspension when I come.outside my rear end driver side is lower

This needs hands on troubleshooting, plain and simple. Compressor failures will fail to raise or vent the vehicle properly. This does not appear to be what is happening here. I would be focusing on the individual air springs and checking for any chassis related diagnostic trouble codes that could be related to an individual strut not operating properly. A Hyundai GDS diagnostic tool (or equivalent) is essential for this diagnostic testing. www.repairpal.com/repair-shops
