Best/ Worst JDPower Vehicle Reliability Survey

In the past two weeks, we introduced and analyzed J respectively. D. Power New Car Quality Survey related information in the United States and China. This week, let's look at J again. D. According to Power's survey on the reliability of new vehicles, vehicle reliability (VDS) is also an important measure of the quality of automobiles. Investigation of this data also has a guiding role in the automotive market. In this issue of J. D. In the Power New Vehicle Reliability Interpretation article, the editors are still based on the survey data in the United States first, and are analyzed based on the important and characteristic data shown in the chart.

● What is a vehicle reliability survey?

The Vehicle Reliability Study (VDS) is called the Vehicle dependability Study in English. It is a measure of the reliability of a new vehicle. The vehicle content includes nine aspects: appearance, driving experience, configuration, control, and dashboard. , audio entertainment systems, seats, air conditioning systems, interiors, engines and gearboxes.

●J. D. How does Power investigate vehicle reliability?

The Vehicle Reliability Survey (VDS) is based on the consumer's purchase of a car for a period of one year and summarizes the various faults encountered. The scope of the survey is based on the body's appearance, driving experience, configuration, and engine. The 9 major aspects mentioned in the above paragraph are as follows. There are 217 detailed items. In other respects, the contents of the two surveys (new vehicle quality survey and vehicle reliability survey) are exactly the same. The result analysis is also similar to the IQS, and the PP100 (the number of problem points per 100 vehicles) indicates that the lower the score, the higher the reliability.

● What is the difference between Vehicle Reliability Survey (VDS) and New Vehicle Quality Survey (IQS)?

After understanding, we found that the biggest difference between the Vehicle Reliability Survey (VDS) and the New Vehicle Quality Survey (IQS) is that the survey has a different time frame. The former is based on one year after the consumer purchases a car, and the latter is based on the consumer's purchase. 2-6 months for the standard research work.

Investigate the time to purchase the vehicle during the period of 2-6 months after purchasing the vehicle . ● J. D. Power US Regional Vehicle Reliability Survey

Through the Internet, we have found a vehicle reliability survey report for the United States from 2003 to 2011, which is the same as the previous analysis of the new vehicle quality survey. The editor here does not list the annual chart for everyone, but instead focuses on the key information. Explained. The specific year report image you can view on the third page.

â—† Most reliable award winner: Lexus

In the list of U.S. regional vehicle reliability surveys for the nine years from 2003 to 2011, Lexus topped the survey list five times, and won the first place in the reliability survey for four consecutive years between 2003 and 2006. In the four survey rankings, Lexus, although not achieving the first result, still ranks high.

â—† Most Unreliable Award Winner: Land Rover

During 2003-2011, Land Rover’s ranking in terms of vehicle reliability still did not satisfy people, but from the brand’s achievements in new car quality, this did not exceed our expectations. Judging from the trend of the polyline in the chart, Land Rover has been at the bottom of the vehicle reliability survey since 2003. It has not improved much in 9 years, and has achieved the bottom of the survey ranking 5 times. Therefore, the most unreliable award is awarded by Land Rover. "Do not let it go."

â—†Disgraced and then brave winner: Mercedes-Benz

Mercedes-Benz, as one of the troikas of German cars, has a profound influence in the international market both in terms of brand value and high-end product positioning. It has never caused consumers to question the quality. It is beyond our expectation that from 2003 to the three years of 2005, Mercedes-Benz ranked higher in terms of vehicle reliability, later in the period of 2006-2009 and 2009-2011. In terms of reliability, it has made two major steps. Until 2011, Mercedes-Benz has risen to the 8th position in the survey of vehicle reliability. Mercedes-Benz’s attitude of knowing shame and braving is worthy of our recognition, but its performance in reliability surveys is inconsistent with its brand value over the years.

â—† Most Active Award Winner: Subaru

From the chart, Subaru is extremely unstable in the 9-year survey of vehicle reliability. During the period from 2006 to 2008, Subaru once had a significant ups and downs. In 2007, it reached the peak of the 9-year survey. , scored the ninth place, and then immediately fell to the lowest point in nine years after one year, ranking 22nd. This erratic ranking movement has made Subaru the most "active" winner.

Next, based on the ratio of nationalities, we will present the top five cars and the bottom five cars in the new car quality survey for the nine years from 2003 to 2011. The specific calculation method is: During the nine-year US vehicle annual vehicle reliability survey from 2003 to 2011, the top five and the bottom five cars were selected, and then the nationality was used as the unit to calculate and calculate the model of each country in the questionnaire. The proportion of the total. (including the top five most reliable and the last five most unreliable)

The above pie chart makes everyone intuitively see that the U.S. Department has occupied 47% of the U.S. Department, which accounts for the vast majority of vehicle reliability surveys. Eighty-seven percent of the remaining 13 percent were occupied by German cars and British cars. In this way, in the 2003-2011 US homeland reliability survey, the American model is the most reliable.

Let's take a look at the cars ranked in the bottom five of the new car reliability surveys. Six countries participated in the survey. The British and Japanese departments ranked 27% in the reliability survey ranking, and the Korean cars ranked second. Followed by it, it reached 16%, followed by 13% of German cars and 11% of American cars. Finally, Swedish cars accounted for about 7%.

Next, we will use the 2003-2011 new car quality survey and vehicle reliability survey to conduct a comparative analysis of the trend of failure rate passing scores to see how much the gap between the two is.

Before analyzing the charts, the editor will briefly introduce the difference between the IQS (Vehicle Quality Survey) and the VDS (Vehicle Reliability Survey). The former is based on the survey conducted one year after the consumer purchased the car, while the latter Consumers conduct research work for the standard 2-6 months after the purchase. Therefore, according to common sense, because the vehicle reliability survey is longer in time, the failure rate value should be higher than the failure rate value of the new vehicle quality survey.

From the chart, we can see that both the new vehicle quality survey and the vehicle reliability survey have generally improved in terms of failure rate passing scores in the nine years from 2003 to 2011. The faults and grid lines of the new car quality have been improved. From the initial 133 failures per 100 vehicles to 107 failures per 100 vehicles, the failure and gridlines of vehicle reliability dropped from the initial 273 failures per 100 vehicles to today's 151 failures. One hundred cars. Over the years, the quality of new cars has made significant progress in the United States.

By comparison, we can also find that in the 9-year survey in the United States, the gap between the failure rate test standard for vehicle reliability surveys and the failure rate pass criteria for new car quality surveys is narrowing year by year. In 2003, the gap between the two was 140 failures per 100 vehicles. In 2011, the gap between the two was only 44 failures per 100 vehicles. From this point of view, major automobile manufacturers in the United States have also improved the long-term quality assurance of their products over the years so that they can perform outstandingly in vehicle reliability surveys. (PS: The survey on the reliability of new vehicles involved in this article is only for the United States and has no connection with the Chinese market)

Editor's note: The Vehicle Reliability Survey (VDS) is also a key reference for car quality measurement. Its survey results will provide consumers with a strong brand of car for a period of one year. Therefore, it is a guiding role for the market. it goes without saying. For automakers, the new research project will give them more pressure and it will also be a driving force to improve their auto products.
