To elaborate on the reliability data from CR……..
They collect reliability data on 17 “potential trouble spots” for cars their subscribers own in their annual auto survey. The ratings go from
much better than average
better than average
average
worse than average
much worse than average
For the Clarity, 15 of the 17 trouble spots rate as “much better than average” in reliability. The other 2 trouble spots (drive system and body integrity) rate as “ better than average”. From this, CR calculates the 2018 Clarity PHEV will be “much worse than average” in reliability. Go figure.
“Drive System” problems reported to CR are likely related to operation of the ICE, as discussed on this forum in several threads. “Body Integrity” problems reported to CR may stem from the door and trunk closing issues some have noted on this forum.
I wrote to the CR auto test director last year and asked about the reliability algorithm used for the Clarity because it went from a predicted “average” reliability to “much worse than average” reliability in just 3 months. I never heard back.
I researched their reliability algorithm some myself and discovered it takes a very small change in percentage of owners reporting a problem to have a car go from average to much worse than average. For example, in their description of how the numbers are crunched, they write that an additional 3% of owners reporting a problem will change a rating in a specific CR trouble spot from average to much worse than average. Or, if 3% fewer owners report a problem, the trouble spot will go from average to much better than average. Given the very small sample size they had for the Clarity, that shift (of less than 3% in this case because the shift was only to “better than average” from “average”) was likely caused by only a few owners at most.
The Clarity does rate “above average” in “owner satisfaction”, another data point from their annual survey.
I try not to be obsessed by the CR rating of the Clarity PHEV as much worse than average in reliability and the CR ranking of dead last among mid-size cars. But, that information does not represent my experience at all. Sadly, given the influence of CR in the marketplace, their ratings and rankings undoubtably affect value.
