I have tried on multiple occasions to charge my 2019 (28) at EA DC 150KW charger and keep getting charging error. Any suggestions?

My 2019 Ionic Electric is due for 15k mile service... Has anyone found a service provider, that is NOT a Hyundai dealer that they feel does a good job with tire rotations, alignments, and brake inspections & repair?? I live in San Bernardino, CA... has anyone tried a national chain, or...
