I was able to get my car in quickly, late in the afternoon, for them to look at it. They performed a thorough analysis of all systems and identified a bad battery cell. While it was not until the next morning they they received a new battery, the replacement was performed immediately. Yes, I paid more than I hoped it would cost, but I got the peace of mind that their diagnosis showed no other issues, and I will be able to return to my home in another state without further worry.
