Ummm, guys, what Mazda and Lexus did was not really motivated by customer service but rather, to avoid the possibility of a lawsuit.
The Mazda case is well documented and actually, not the first time, it happened with the Miata couple of years back as well, same problem, product had much less horsepower than advertised.
Here's a quote from a car news site:
"Detroit News featured a note that automakers can no longer make inaccurate performance claims. Blueovalnews.com's exposure of Mustang "under-horsepower" gave Ford a black eye (and gave blueovalnews.com a lawsuit), and Nissan and Ford both compensated owners for inaccurate claims (the 2001 Miata was sold as having 155 hp but really only had 142 hp). The latest "offender" is Nissan's Infiniti Q45, whose 0-60 times apparently may be about a second longer than company claims (Nissan explained that the Q45 used in testing was lighter than the ones supplied to journalists, was tested by light people, and was run under the best possible weather and altitude conditions)."
If a manufacturer advertises a particular specification clear enough and without the necessary disclaimers or update to their information if the product has changed, customers are in their every right to sue for deception or false claims.
In the case of the radio, there aren't any false claims involved at this time, they never advertised "a bright radio display".
It really isn't even faulty BUT it should work better. The new Toyota Camery has a similar problem now with their radio, the display (also LED) is not visible if you have sunglasses on because of the type and angle of polarization they used on the display. This problem was highlighted by a Car and Driver TV segment.
Now, if people who are familiar with NHSTA requirements can show that the current condition of the radio promotes a serious safety hazard, then that's a totally different story, we can all sign up and threaten a class action suit.
I'm lobbying for the radio to be replaced as well, there aren't any good aftermarket radios that really fit the same shiney silver plastic, but let's not compare apples to oranges to get there...unless we can turn this apple into an orange
