But given that this condition has only shown up in early production cars that are operated in severe environments, that many have higher than average mileage for their time-in-service, and that this condition has not affected cars that were made after the late summer of 2011, or in cars that are operated in less severe conditions or have lower time-in-service/miles driven ratios, leaves this possibility quite probable.
In this scenario, this bug is present in all cars that were manufactured prior to say August 2012, but only those cars that have been driven in a severe and high-mileage mode trigger the condition.
Given the relatively small number of cars from the entire fleet that have this issue, it is totally possible.
Granted, my car is in a hot area of the country, but it was manufactured in 8/11, originally sold to Hertz in Oct 2011, has only 1200 miles on it, obviously has a very low number of charge cycles on it (due to the low mileage), and yet it already has 10% capacity loss as measured by Gidmeter.
My car might be considered a hot weather "control" car because of the low usage in the 12 months since it was manufactured. However, my car does not completely fall within your proposed scenario listed above.
