Lexus Places Second in J.D. Power 2007 Initial Quality Study

J.D. Power & Associates published the results of their 2007 Initial Quality Study, and Lexus placed second in the overall rankings, behind Porsche:

J.D. Power's 2007 Initial Quality Study Results

As you can see, it was a very close race, with Lexus owners reporting 94 problems per 100 Vehicles as compared to Porsche’s 91.

The individual vehicle results were less flattering, with only the RX 350/400h placing first in its class.

Midsize Premium Car

1. Mercedes-Benz E-Class 2. Lexus GS 350/430/450h 3. Infiniti M-Series/Volvo S80

Large Premium Car

1. Audi A8/Mercedes-Benz S-Class 3. Lexus LS 460

Premium Sports Car

1. Mercedes-Benz SL-Class 2. Porsche 911 3. Lexus SC 430

Midsize Premium MAV

1. Lexus RX 350/400h 2. Lincoln MKX 3. Lexus GX 470

As for the rest of the the Lexus lineup, the ES 350, IS 250/350 and GX 470 all failed to place in top three of their respective segments.

All in all, a strong showing for the brand, with just enough room for improvement to keep them on their toes.

  1. Reflecting on Initial Quality : The Passionate Pur

    [...] not Lexus specific, Joseph B. White of the Wall Street Journal has taken a deeper look at J.D. Power’s Initial Quality Survey and is driven to wonder, Is Initial Quality still relevant? Now, most of the major auto makers have [...]

  2. Agreed.  INITIAL quality is of minor significance.  how many people trade their cars every 90 days!!???

    much more significant are longer spans like 3 years, 4-7 years, and even 10+ years, for those who buy cars to drive “until the wheels fall off.”  and for those who don’t, getting a quality, reliable car still pays off with higher retained values at trade-in time.

    from that perspective, regardless of 90-day ratings, ONLY TWO car companies have less than 100 problems per 100 vehicles after 10 years:  Honda and Toyota (includes Acura, Lexus).

    most Euro brands get to that 100/100 point in about 5.5 years or less.  best non-japanese brand is ford, which takes 7 years.

  3. source of the above data, is Consumer Reports, with a much longer history and far better reputation than JDP.

    also, how nitpicky are the standards of THIS study, when most of the supposedly new cars are already getting 100 and more “problems” per 100 cars?

    most OTHER studies put the figure at a mere 12 to 19 problems/100.

  4. True Delta, a competitor to JD Power, put together a rather substantial rebuke to the Initial Quality Survey.

    The main criticism is that the IQS has grown from production issues (problems with build quality) to design issues (problems with the car’s actual design).

    Design by its very nature is subjective, and to include it in the results of a survey of initial quality seems curious. After all, these aren’t necessarily problems, but rather issues that the car owner finds annoying.

    This explains the high scores, but why does JD Power do it? Here’s a quote from the above article:

    It’s becoming clearer why J.D. Power lumps design quality into the IQS: without it the absolute differences become small. And the smaller the differences get, the less people will care about IQS. And the less people care about IQS, the less manufacturers will be willing to pay lavishly the detailed findings and for the right to advertise top scores.
