When at a DCFC it is getting DC directly from the station.Did you read my long thread?They are going to give you a spiel about the next thing in their official trouble tree is to replace the $800 SDM.Evidently GM can not do scientific troubleshooting and simply follows an old fashioned Trouble Tree. Beg them not to do that nonsense. It is not the problem. It is HPCM 2 (I think, read my thread) that handles the DCFC functions.I can give you an email address at GM if your dealer won't play nice.However, my car never gave me 'Reduced Propulsion' msgs. So yours may have other problems also.  Time to bale out? I would and let Carvana get it fixed and then you buy it later.</blockquote>
