Lexus Tops J.D. Power Reliability Ranking for the Second Consecutive Year

Lexus has retained the top spot in J.D. Power’s annual vehicle dependability survey for the second year in a row, after three years of ownership, even though long-term quality and reliability in the industry slightly declined after improving in 2023.

Toyota, ranked second, was the top-performing mass-market brand in terms of dependability, dethroning Kia, which held the title for three consecutive years. The average number of problems per 100 vehicles increased to 190 in the latest study, up from 186 in 2023, due to various challenges faced by automakers.

According to Frank Hanley, senior director of automotive benchmarking at J.D. Power, the average age of a vehicle on the road is 12 years, raising questions about the ability of these new technologies to meet customers’ needs in 12, let alone three years.

The survey also revealed that many cars assessed for dependability were built in 2020 and 2021, a period when the COVID-19 pandemic disrupted global production schedules, parts supply chains, and logistics.

Which is the most reliable brand? According to J.D. Power’s Vehicle Dependability Study, Lexus ranks first among luxury brands, while Toyota ranks first among mass-market brands.

J.D. Power’s Vehicle Dependability Study evaluates problems per 100 vehicles over a 12-month period reported by three-year-old vehicle owners.

At the top of the list, the Vehicle Dependability Study evaluates problems per 100 vehicles over a 12-month period reported by three-year-old vehicle owners. The survey queries owners about their experience in nine major areas including climate controls, driving assistance, driving experience, exterior, features/controls/displays, infotainment, interior, powertrain, and seats.

Infotainment technology again generates the most reported problems by owners, with Android Auto and Apple CarPlay connectivity topping the issues, followed by voice recognition software.

Electric vehicles also generate more problems than plug-in hybrids and gas vehicles, according to the survey. Tires are particularly problematic, with 39% of EV owners reporting having replaced their tires within three years of purchase, compared to only 20% of gas vehicle owners.

The survey also revealed an increase in problems related to driver assistance systems.

The Porsche 718 was ranked as the most reliable model in the industry, according to the survey. The Toyota C-HR and Lexus RX tied for the title last year.

Rising issues across all manufacturers J.D. Power stated that the number of problems reported by owners increased for nearly two-thirds of the brands evaluated. The brands showing the most significant improvement were Porsche, Mercedes-Benz, and Toyota.

While Lexus remained at the top, it reported two more problems on average than the previous year, with 135 problems per 100 vehicles. Kia, which won the award in 2022, dropped five places to eighth, with an average of 187 problems per 100 vehicles. Genesis, ranked second in last year’s survey, dropped to 16th place, with an average of 200 problems per 100 vehicles.

In 2022, the three Hyundai Motor brands – Hyundai, Kia, and Genesis – were among the top five. This year, only Kia is among the top ten, with Hyundai ranking 13th.

Hanley stated that 2021 was “a very important launch year for the three” brands. “One thing that we observe across the industry is that a [new vehicle launch] tends to increase issues,” added Hanley. “It’s not abnormal for anyone in the industry.”

General Motors took the 3rd and 4th spots with Buick and Chevrolet.

J.D. Power’s U.S. Vehicle Dependability Study in 2024, conducted from August to November 2023, is based on responses from 30,595 original owners of 2021 model-year cars and light trucks after three years of ownership.

The latest study includes responses from Tesla owners for the second time, with the EV manufacturer scoring 252 problems per 100 vehicles, up from 242 the previous year. Tesla remains unranked as the brand does not allow J.D. Power access to owner information in states where such authorization is required by law.
