i'm thinking the same thing.. though i won't really know until i get the paperwork. i will test drive and if i purchase the car will take it to a dealer for a thorough going-through. there are a few months left on the 3/36 so perhaps what they find will be covered.
odd that it will take 3 days to repair though.. if simply a ground cable bolt. simple repair in other vehicles i've owned.. just wondered if it were something different in the volt.
A grounding issue can affect ANY vehicle.
To the best of my knowledge there is no "chronic" grounding issues present on the Volt (or the Cruze for that matter)
In any case they are easily repaired for the most part. Usually it's as easy as remove, clean, and tighten.
The "delay" might be them waiting for parts to repair a bad ground though.
There are special repair processes for things like grounding studs on body panels, riv-nuts, and specially plated fasteners, etc that they might be waiting for.
IMO nothing to worry about for the most part , but get them to explain what exactly they did if only for your own peace of mind
