I left out another important factor to consider...
CR's ratings of any given model varies year by year. Not just model year by model year, but this year they rate the 2018 Clarity 1/5 in reliability, next year, it could be quite different. The current Civic came out in 2016. A year or two ago, the 2016 was rated at 1/5 (much worse than average), and now the 2016 is rated as 4/5 (better than average) in reliability. Now, since it is based upon how a car fares v. the average, it is possible that Hondas have more initial issues than other makes (especially other reliable makes), but that it ages better than most. It is possible that they are statistical anomalies based upon who choose to return the surveys in a given year. It is also possible it has a completely different cause. CR doesn't really address that, and it is just speculation as to why it happens. However, it is one of many reasons IMO to consider what they say, but to consider the larger picture as well and not take their current ratings as gospel.
