I don't have a subscription (dropped it after the early CR Volt bashing), so I don't have the detailed list.
I just checked online. I can't find a complete list, but CR lists the best and worst for each brand. The Volt is the most reliable Chevy. The Volt is listed as 37% Better than average, while the Corvette is 43% worse than average.
Another interesting comparison: Nissan Armada: 101% worse than average, while the Leaf is 54% better than average. Since Consumer Report's reliability is self-reported by owners I suppose the Leaf would be actually be higher if it weren't for the battery degradation in etremely hot areas. (Or maybe Nissan intercepted the Consumer Reports surveys destined for households in near the Mexican border...heh heh)
