AutoNation Chevrolet Airport

I took my Volt in for an intermittent electronic control module problem that I had experienced before in another state, where my car ended up being down for 3 months. I showed videos to my advisor to help understand the issue. I wanted to show the 1 EV tech they had, but he was not available. Advisor swore up and down he'd be able to pull codes from the car, and 6 hours later I get a call back saying no codes came up, tech couldn't reproduce the errors and what I though I was experiencing was just my EV battery idling high to charge the battery. Since no codes populated, they can't help me. If I would have been permitted to speak to the tech and show him first hand, if I would have been heard by the advisor and if the checkout process would have gone differently, I likely would have given 5 stars...but those things didn't happen
