We’re all aware that buying a first-year car can be risky, especially early in its production run. But how soon does the risk go away? Conversely, a new car model can initially seem problem free, only to have a common problem pop up once the cars have a few thousand miles on them. To cover both scenarios, TrueDelta promptly updates its car reliability stats four times a year, not just once a year after a half-year delay. Our recently updated reliability stats over owner experiences through the end of September 2011.
Put another way, the stats you’ll find elsewhere cover the same time period TrueDelta’s did two updates ago, back in May. How much difference can half a year make? In the case of some new Fords, quite a bit. A year ago the Fiesta had a reported repair frequency of 130 repair trips per 100 cars per year, about three times the average. Six months ago this had improved to 102, still much worse than average but heading in the right direction. With the latest update it’s 66 and within the range we consider “about average,” if still a little on the high side. Our earliest data for the 2012 Ford Focus suggested that it might similarly have a buggy launch, but after including more recent months its stat is 42 repair trips per 100 cars per year, very close to the average. Ford appears to have fixed the early bugs very quickly. But not quickly enough: other sources, using survey data from last spring, will report “worse than average” for at least the next year.
