Even "Consumer Reports" Can Be Wrong

Posted November 20, 2015 12:00 AM by Engineering360 eNewsletter

Few quality adjudicators have a better reputation for unbiased analysis than Consumer Reports. Back in August, the organization awarded Tesla Motors' $130,000 Model S with the highest quality rating ever, an improbable 103 out of 100. More recently, however, the rating service has withdrawn some of its accolades. Apparently, although the car's out-of-the-showroom quality rating remains high, reports from drivers are less complimentary. Numerous reliability problems have ranged from the innovations, such as its touchscreen dashboard and state-of-the-art software, to more mundane issues such as warping brakes. Although Tesla fixes the problems under warranty at no cost to the cars' owners, reliability questions have dented the carmaker's reputation - and made investors and future car-owners at least a little skittish.

'Even'?

I've always found their reviews (car reviews in particular) to contain a fair amount of bias. I.e., how they choose to rate cars, and their weighting factors, reflect the lifestyle and attitudes of their writers and test personnel.

I've learned to be fairly skeptical of their reviews, and throw them in the mix with other car review sources. What 'Consumer Reports' rates as good is often quite different from what, say, 'Road and Track' thinks is good.

GA. That was my same sentiment regarding the "even", like CR is some infallible organization. They are people, subject to the same foibles as the rest of us.

They can only be right at any time to a certain percentage and a specific moment in time...it's still a crapshoot as to whether your gizmo is going to work as advertised...things change too fast for them to be accurate, and their sampling of the product is a small percentage...by the time you read the article they have changed component supplier or design characteristic for profit optimization...the environment that the gizmo is used in also varies, and the interaction with the owner varies, the handling of the gizmo presale varies, everything varies...

Two fold problem with magazine reviews:

1. Not all cars produced on the same assembly line are equal. The individual parts all have tolerance limits. If you get one with more parts near the limits, well.... (I have personal proof of this one)

2. They have a limited time to test. They can't really tell us what happens after normal wear and tear of 75000 miles, or the reviews would be three to five years old.

It might be interesting to read their original report on the Cavalier when it first hit the market. Do they have an archive?
