Lexus J.D. Power Vehicle Dependability Results

J.D. Power Vehicle Dependability Study 2010

J.D. Power and Associates has released the results of its annual Vehicle Dependability Study (VDS) for 2010.  In the study, Lexus took third position in a tie with Buick, earning an average score of 115 problems per 100 vehicles.  Just ahead was Lincoln (114), moving up from seventh last year, and taking the lead was Porsche (110), moving up from ninth place last year. Lexus also won a segment award for the GX 470, which beat out the RX 350 for the Highest-Ranked Premium MAV. The ES 350 and LS 460 placed second in their segments to the Audi A6 and Cadillac DTS respectively. Survey details from J D. Power:

The study, which measures problems experienced by original owners of three-year-old (2007 model year) vehicles, includes 198 different problem symptoms across all areas of the vehicle.  Overall dependability is determined by the level of problems experienced per 100 vehicles (PP100), with a lower score reflecting higher quality.

Overall vehicle dependability has improved by 7 percent in 2010 to an average of 155 PP100, compared with 167 PP100 in 2009-a rate that is consistent with historical industry gains. In addition to the improvement in overall dependability, the rate of component replacement has also been reduced from 2009. Approximately 65 percent of owners indicate they replaced a vehicle component in 2010, compared with 68 percent in 2009.

Historically, Lexus has done well in the VDS, taking the top spot every year from 1995 to 2008, and ranking in the top three since 2009.  Lexus’ score for 2010 (115) is an improvement over 2009 (126) and 2008 (120).  With the 2010 VDS measuring vehicles purchased three years ago, this year marks the introduction of the 2007 LS 460 and ES 350 into the long-term survey pool.  Both models have a hefty legacy to follow, with the prior ES 330 having been the highest-ranked premium mid-size model and the LS 430 the highest-ranked vehicle among all cars in past editions of the VDS. The 2007 model year also represented Lexus’ highest-ever US sales total, with the luxury division gaining more customers than any of its quality rivals.

The 2010 VDS rankings further mark a shift in the survey leaders compared to 2009, when Buick and Jaguar tied for first, followed by Lexus.  The addition or removal of certain models in the survey reportedly had a significant effect on Porsche and Jaguar VDS scores.

  1. hmmm… new vehicles usually have a lot of problems, but could it be that in 2007 the growth of the Lexus lineup and sales volume interfered with quality? ...or that when there are more mothers driving RX’s (refreshed in 2007), more realized that something was not normal with their RX - problems usually ignored in average cars and Mercedes?

    Is Vehicle Dependability the survey that Lexus usually scores less than 100 in?

  2. @WorldofLuxury: Lexus hasn’t ever scored less than a 100 in the VDS manufacturer ranking, in fact no carmaker ever has in the history of the study.  Above, there are Lexus’ scores for recent years: 2010 (115), 2009 (126), and 2008 (120).  It was the LS 430 that was the first car ever to score less than 100, which means that the average LS 430 has less than 1 problem after 3 years (or practically no problems).  But that is an individual model score and not the whole make’s score. I do believe that the introduction of new models in 2006 and 2007 showed up in the 2009 and 2010 VDS manufacturer results for Lexus.  The LS 430 itself also had higher scores (more complaints) in its early years vs. late; one notes that the DTS which assumed the luxury sedan class leader after the LS 430, is on the end of a 6 year model cycle.

  3. @Dan: LOL There is recall information of the HSh on Lexus USA’s website. There seems to be ABS problems. My LS was like that with Lexus’ (then) new VSC system. It was so annoying! VSC randomly engaged and the car wouldn’t move, and it took quite a few visits to the dealer to fix the problems.

    And now, I just have to use the right tires and appropriate brakes to keep the system working properly (in other words, use the expensive ones, particularly the ones from the Lexus dealers).

    One good thing is that in my LS, the VSC can be turned on to save my life, prevent me from getting into too much trouble, let me slide on slippery grounds and come to a safe and complete stop, and… it can be turned off COMPLETELY to have some good ol’ FUN!!! LOL LOL LOL

  4. @WorldofLuxury: Yeah, the HSh ABS software update is related to the Prius software update, mainly ABS kicking in on uneven or rough surfaces.  It’s possible that this recall may show up in the 2013 VDS (directly), or as an aggregate effect or owners looking for presumed issues, earlier or later. Also whoever decided to put that black recall banner on, it looks tacky, why not just integrate it into the flipper box below or next to it.

    Your experience with the LS VSC system is interesting, good to hear how it was dealt with and that there is an off button. smile

  5. Buick Lincoln and Mercury more dependable than Honda and Toyota?  I’m shocked.

  6. Hope ... Lexus & Toyota Can Go Well After March Of 2010 ... smile
