How reliable are the cars? The ranking of JD Power


“Solidity” and “reliability”, we often talk about cars. However, there are objective methods to assess how prone a car is to fail. JD Power has been working on it for some time, and each year draws up the ranking of the most reliable brands.

The study found the number of reported problems on 100 vehicles over the past 12 months. The 2021 report is based on the answers given by 33,251 US owners of 2018 models who then declared the problems encountered in the first three years of the car’s life. The data was collected from July to November 2020. And here’s what emerged.

To give a first clue, the general average level stands at 121 problems for every 100 vehicles involved in the survey. A lower value than the 134 of the report published in 2020. At the top of the ranking is Lexus with 81 reported failures per 100 units. This is the second statement in the last three years for the Japanese premium brand.

In second place we find Porsche with a value of 86 thanks to the few problems found on the 911, the top model of the German brand. Third position instead for Kia with 97.

At the foot of the podium is Toyota with 98 problems per 100 cars and four brands with very close values. Paired at 100 there are Buick and Cadillac, two brands currently not present in the European list.

The result of Hyundai and Genesis is practically identical, a result that is relatively surprising considering that the latter is the premium brand of the South Korean house. Genesis, after having won the JD Power 2020 ranking, therefore drops to eighth place. However, a satisfactory result for a brand that should soon land in Europe too.

Immediately below the average of 121 are Mercedes (122) and Dodge’s Ram division (123), which focuses on pickup production. However, also in this part of the ranking, very close values ​​can be seen for brands that are aimed, however, at significantly different audiences.

The results below average

The results of the British Jaguars and Land Rover were quite negative. The Jaguar brand is in third last place with 196 problems, while Land Rover is even last with 244. Basically, according to these values, a car has reported at least two problems of various kinds in the last three years.

Bad also Alfa Romeo that comes in penultimate position with 196 problems. Tesla’s score is not exceptional either, introduced for the first time in the JD Power ranking. Elon Musk’s House scores 176 problems for every 100 cars. In this case, however, the survey was based on Tesla owners in only 35 US states, as the manufacturer did not allow JD Power to conduct the interview in the other 15 states. For this reason, it is excluded from the ranking which, instead, is based on the opinion found throughout the United States.

Volkswagen, on the other hand, has fallen from 6th position in 2020 to 23rd in 2021. Honda has instead moved from 14th to 22nd this year. FIAT was not included as the sample of cars sold in the USA was not sufficiently representative.

A technology that makes you angry

Presenting the data during a webinar, JD Power’s Dave Sargent said Tesla’s negative result was mainly due to car building problems. A strength of American electric was instead the powertrain.

Sargent also admitted that “most of the cars involved in the survey did not report serious problems, but rather malfunctions in on-board technology”. Among the categories affected by the survey, communication devices, infotainment and navigation showed minimal improvements compared to previous reports. These aspects therefore remain the most critical according to the owners.

Overall, results show some confirmations with respect to the survey conducted by Consumer Reports. This latter ranking, elaborated in a different way than JD Power, showed Mazda, Toyota and Lexus in the top three places. Fourth and sixth place, however, for Buick and Hyundai.

Three of the most reliable Kia models

JD Power’s analysis also covers individual market segments. In this regard, we remind you that the classification of segments in the United States is different and more multifaceted than the European one.

Note the excellent result of Kia which placed Optima, Sportage and Sorento respectively in the Midsize, Small SUV and Midsize SUV segments.

Among the Premium SUVs we find Mercedes GLA, Porsche Macan and Lexus GX (whose electric version is coming to Europe). Among the “compact” Volkswagen Beetle, Lexus ES and BMW 2 Series achieved excellent placings.
