Unraveling The Mystery Of Consumer Reports' Brand Spread

Michael Karesh
by Michael Karesh

Some things have been repeated so often that many people have come to accept them as facts. I tripped across one of these in Bob Lutz’s new book, Car Guys vs. Bean Counters (review on the way). Lutz offers “a curiosity I have observed several times at various stages of my career”: when the domestics rebadge an import, the resulting model has scored “way lower” in Consumer Reports reliability survey. This has been Exhibit A in the argument, also repeated by Lutz, that import owners under-report problems on surveys in order to “retroactively justify the wisdom of their purchase.” I’ve come across this claim about CR so many times in the past that it just had to be true. Then I checked.


The cars Lutz mentions: Eclipse / Laser, Corolla / Prizm, and Matrix / Vibe. I happen to have some Consumer Reports annual auto issues from the years in question. In the 1992 issue, the Plymouth Laser and Eagle Talon sometimes scored lower than the Mitsubishi Eclipse, and sometimes scored higher, depending on the model year and powertrain. The differences are mixed and never substantial. CR pooled the samples for the Diamond Star hatches beginning with the 1993 issue, so the scores for the triplets were absolutely identical from that point on.

Also in the 1992 issue, the Prizm scored lower than the Toyota Corolla, but just by a little, not “way lower” as Lutz states. In the 1995 and 1996 issues the Prizm actually scored higher than the Corolla, with the margin in the former year a substantial ten points.

With the Vibe and Matrix, Lutz gets his snark on. “Have you been paying attention? Test question: which of the ‘twins’ performed better in quality surveys?” Well, in the 2005 issue the Pontiac Vibe and Toyota Matrix had virtually the same scores, with both better than average. In the 2009 issue the Matrix scored a little higher than the Vibe, but in the 2007 and 2008 issues the reverse was true. In fact, in the 2008 issue the Vibe had the highest score in the entire “wagons and hatchbacks” category. It seems that Lutz either wasn’t paying attention or saw the unfair playing field he wanted to see, didn’t check the facts either way (always a good idea), and consequently failed his own test.

    The one major flaw in this article is there are no numbers given except when an American branded car beat it's twin. Why are there no numbers given? I'm no expert in statistics but I know that margin of error becomes lower as the sample size increases. If the difference between two identical cars with different brands is outside of the margin of error then bias is likely the cause. How far outside of the margin or error were the results? Without hard numbers to back up their claims Bob Lutz's AND Michael Karesh's assertions are both garbage. Another interesting bit of information brought up was that CR merged the results of cars that are twins or triplets. I'm not a conspiracy-minded person but I have to wonder if it's possible CR did this in part to avoid the controversy regarding the bias of consumer union members. Here are some observations of mine that are not backed up by numbers but are hard to ignore. Just the fact that "twin" cars such as the Corolla and Prism SOLD in vastly different numbers shows bias of consumers. Beginning in the 1980s Japanese brand cars did very well in reliability according to Consumer Reports. I don't dispute this at all but not all Japanese car makers are equal. In Consumer Reports Mitsubishi ranks very, very low yet car buyers keep purchasing Mitsubishi cars because they think all Japanese cars are superior. Another misconception is that Japanese cars are ranked number one in consumer reports and American cars ranked worst and European cars are in the middle. According to consumer reports it's European cars that are the most unreliable and American cars were in the middle. A friend of mine purchased a Volkswagen Toureg which is one of the most problematic vehicles according to Consumer Reports, J.D. Power and Associates and my friend, David, who warns everyone he knows not to buy a Volkswagen.

    This theory can be taken a step further: As a BMW and Benz owner, I am typically obsessive and likely to notice and complain about unsatisfactory details. I have always suspected this is why these brands don't typically score so high on Consumer Reports surveys and such. A typical Camry owner, by contrast, is just happy to have an appliance that starts and rolls to its destination...ergo, few complaints. I have always been happy and impressed with the BMWs and Benzes, and willing to have necessary maintenance done on them, but my detail orientation allows me to see the most minor flaws. My expectations are higher. Bottom line: Consumer Reports is crap when it comes to cars, as we all know.

  • Ronin Let's see the actuals first, then we can decide using science.What has been the effect of auto pollution levels since the 70s when pollution control devices were first introduced? Since the 80s when they were increased?How much has auto pollution specifically been reduced since the introduction of hybrid vehicles? Of e-vehicles?We should well be able to measure the benefits by now, by category of engine. We shouldn't have to continue to just guess the benefits. And if we can't specifically and in detail measure the benefits by now, it should make a rational person wonder if there really are any real world benefits.

  • TheEndlessEnigma Top Gear of the 2000's was a fresh concept and very well done. Sadly to say there isn't a TV show concept that doesn't eventually exhaust fresh ideas and, as a result, begins to rehash and wear out once were fresh ideas. The show eventually becomes a pale imitation of itself, then begins to embarrass itself, it will get to a point where it jumps the shark. Top Gear began to get stale, the Clarkson, Hammond and May left and the formula failed - surprise! the presenters were part of the magic. Fast forward many years and Grand Tower is trying hard to be Top Gear but it's all very obviously scripted (it always was by felt spontaneous in its original form), Clarkson, Hammond and May are much older, tired and have become caricatures of themselves. Guys, just stop. You should have stopped 10 years ago. Now you're just screwing with your reputations and legacies.
