So glad to finally find a shop to actually know how and to give a fair evaluation / trouble shooting report on my Chevy Volt. I have a better understanding now and know more from Mobil Tech than I have ever gotten from the local Chevy dealer which has been expensive and debatable BS. I highly recommend Mobil Tech for any EV or Hybrid vehicles. With most EV/Hybrids, its not a mechanic that is needed to trouble shoot, its an electrician and or a tech who can read and understand the computer programing. Mobil Tech seems to have this.
