Buick, Jaguar pass Lexus to top reliability study

Buick and Jaguar shared first place for brands with the most-dependable vehicles in a study released today, ending Lexus's 14-year reign.




Buick climbed from sixth place last year in market research firm J.D. Power and Associates' Vehicle Dependability Study, and Jaguar soared from 10th. They were followed by Lexus, Toyota and Mercury in the survey of owners of 3-year-old vehicles.

Buick's No. 1 ranking reflects General Motors' efforts to shake a reputation of poor dependability, said David Sargent, J.D. Power's vice president of automotive research.

"Part of GM's historical challenge has been that the customer's perception of GM's vehicles has been not in line with reliability. GM, as well as Ford, has made a lot of strides recently," he said. "Maybe 10 or 15 years ago their vehicles weren't as reliable as some of the imports, but I think today they've virtually caught up."

Jaguar, sold by Ford to India's Tata Motors last year, has fought similar stereotypes, Sargent said. In the U.S., the brand has had a reputation "of being somewhat unreliable."

Original owners of Buick and Jaguar models reported an average of 122 problems per 100 vehicles, four fewer than Lexus. In compiling the rankings, J.D. Power used surveys taken in October of more than 46,000 owners of 2006 model-year vehicles.
 
Recession protection

Dependability is becoming more important to consumers as the recession stretches into its 16th month, Sargent said. Owners now keep their new vehicles for an average of 73 months, up from 66 in 2006, he said.

Toyota Motor Corp. led all automakers with 10 segment-leading vehicles (Scion xA; Toyota Prius, Solara, Highlander, Sequoia, Tundra; and Lexus ES 330, LS 430, SC 430, GX 470). The LS 430 sedan had the fewest problems -- 61 -- reported per 100 vehicles.

Ford Motor Co. followed with four segment winners (Ford Ranger; Mercury Grand Marquis; Lincoln Zephyr and Mark LT).

Other class leaders were made by Honda Motor Co. (Honda Element, Acura RL); GM (Buick LaCrosse); Chrysler LLC (Dodge Caravan); Nissan Motor Corp. (Nissan 350Z); and Mazda Motor Corp. (MX-5 Miata).

Below average

Six GM brands finished below the industry average of 170 problems per 100 vehicles.

The five brands at the bottom of the dependability rankings were all imports. Suzuki finished last; the next-worst was Volkswagen, below Land Rover, Isuzu and Mazda.

Study authors changed their methods slightly for this year's version, their 19th iteration. They added and deleted questions about some components and reworded questions to ask if parts had "broken," instead of just letting consumers call them problematic.

That means small changes in rankings like Lexus' drop from first place are not significant, Sargent said. Buick tied Lexus for the top spot in the study released two years ago.

Consumer Reports has a similar study, which points to reliable used-vehicle models. In its annual April auto issue, the magazine said Toyota and Honda dominated its reliability rankings, based on vehicles from model years 1999 through 2008.

For model year 2006, the Lexus SC, Toyota Highlander and Toyota Prius earned the top three Consumer Reports reliability rankings, based on problems per 100 vehicles. Those vehicles all topped their segments in J.D. Power's study.
 

Sarebbero le peggiori queste??

Mazda   227
Isuzu   234

non mi so spiegare tutta questa differenza tra vw e audi... come affidabilita' non dovrebbero essere poi troppo distanti, o sbaglio?

fa sempre piacere vedere che la toyota va sempre cosi' bene.

Sorprendente, oltre al fatto che Audi fiancheggia Porsche e con un distacco abissale da VW, il fatto che Bmw, premium, è vicina a Chrysler.

Non so come giudicare questo indice, in fondo sono americani.... 

Piu' che la vw in fondo sorprende, imho, jaguar... davvero notevole.

< staff: rimosso su richiesta dell'utente >

mi sembra che dica numero di inconvenienti ogni cento veicoli.dovrebbe essere piuttosto oggettivo

< staff: rimosso su richiesta dell'utente >

Giusto  Si registrano il numero di problemi per ogni 100 veicoli in modo da registrare, nell'intervista, la fedeltà del Cliente al marchio.
Piu alto è il valore e piu scarse sono le performance rilevate su un determinato marchio.

concordo

La Audi è made in Germany, la VW è made in Mexico, hombre.

Qui stiam parlando del mercato Americano. 

As the U.S. economy continues to sputter, consumers are indefinitely delaying many big-ticket purchases. Nowhere is this more evident than on new car dealer lots, where sales are down drastically, and inventory of new vehicles is piling up as consumers opt to hang on to their current vehicles rather than buy new. In fact, the average age of a vehicle at trade-in has increased to 73 months in 2009 from 65 months in 2006. With no end to the nation’s economic troubles in sight, finding a dependable vehicle is even more critical.

To provide both auto industry and consumer audiences insights into the long-term reliability of today’s new vehicles, the J.D. Power and Associates 2009 Vehicle Dependability StudySM (VDS) focuses on problems experienced by original owners of three-year-old vehicles (2006 model-year vehicles). The study is used extensively by the world’s auto manufacturers to help design and build better vehicles—which typically retain higher resale values—and by consumers to help make more-informed choices for both new and used vehicles.

The 2009 Vehicle Dependability Study provides information gathered from over 46,000 original owners. Performance is measured using a “problems per 100 vehicles (PP100)” metric. A lower PP100 score indicates better performance and a higher PP100 score indicates worse performance. The 2009 study covers a total of 202 total problems, broken out into eight major problem categories as follows:


Exterior
The Driving Experience
Features/Controls/Displays
Audio/Entertainment/Navigation
Seats
HVAC
Interior
Engine/Transmission
The study finds that the frequency and severity of component replacement has a particularly strong impact on customer loyalty intentions. Component areas for which the impact is greatest include the Engine/Transmission category. When engine components are replaced or rebuilt, just 11 percent of customers state that they definitely intend to purchase or lease another vehicle of the same make, compared with nearly 40 percent among owners who report replacing no components.

Other highlights from this year’s study:


The average number of problems per 100 vehicles (PP100) for the overall industry has declined this year to 170, which is 36 PP100 fewer than in 2008.
Buick and Jaguar (122 PP100 each) tie for the highest-ranking nameplates in vehicle dependability. Jaguar moves up nine rank positions from No. 10 in the 2008 study. Buick, which ranked No. 6 in 2008 and tied for the highest ranking with premium make Lexus in 2007, has ranked among the top 10 since 2003.
Lexus ranks No. 3, with more than half of its eligible models receiving a segment award. In addition, the Lexus LS 430 sets a new standard in dependability, achieving an industry-best 61 PP100. Toyota (No. 4) and Mercury (No. 5) round out the top five brands.
Lexus and Toyota dominate the majority of the segment awards, with Toyota receiving five awards—Highlander, Prius, Sequoia, Solara and Tundra—and Lexus receiving four—ES 330 (in a tie with the Acura RL), GX 470, LS 430, and SC 430.
Lincoln follows with two awards (for the Mark LT and Zephyr), while Acura, Buick, Dodge, Ford, Honda, Mazda, Mercury, Nissan and Scion each receive one award.

Stiamo parlando di qualita' percepita?? Iniziale?? Lungo periodo??

J.D. Power pubblica diversi tipi di classifiche molto diverse tra loro....

Per quanto mi riguarda, la parola definitiva ce l'ha Consumer Report che stila per ogni modello l'affidabilita' statistica di lungo periodo.

E secondo CR fino a tempi recenti Jaguar era messa abbastanza male...nel segmento Luxury era tra le "Not Recommended"

La migliore delle Tedesche, sempre secondo CR, e' BMW.

Che Jag e Buick abbiano fatto meglio di Lexus e' difficile crederci...sara'...

Si tratta di auto con 1-2 anni di vita??? Riperliamone a 5-6........Chrysler meglio di Nissan o di BMW???....seeee domani.....che chiedano quanto dura mediamente una trasmissione Chrysler...

Mi piace questa frase: "Jaguar, sold by Ford to India's Tata Motors last year, has fought similar stereotypes, Sargent said. In the U.S., the brand has had a reputation "of being somewhat unreliable."

"somewhat unreliable"...ahahah, andatelo a dire ai proprietari Jag inbufaliti....se il marchio ha avuto i suoi bravi problemi c'e' un perche'....

ah, non sapevo.

Ognuno di noi ha dell idee, opinioni o ancora percezioni diverse:
Quello che mi turba è il blocco mentale a non accettare queste indagini e a scaldarsi se le proprie percezioni non vengono suffragate da tali indagini.
È chiaro che queste indagini abbiano i propri limiti statistici, pero' bisogna accettarle come indicazioni di massima.
Il mondo cambia continuamente; perchè continuare a pensare utilizzando i soliti sterotipi su Jaguar, Mercedes o VW?
