Key points from the chart
- The chart ranks 29 car brands by problems per 100 vehicles (PP100) in the J.D. Power 2024 U.S. Vehicle Dependability Study. A lower score means fewer problems.
- Lexus ranks highest overall at 135 PP100, for a second year in a row, and Toyota is the top mass market brand at 147 [1].
- The industry average rose 4 points from 2023 to 190 PP100 [1].
- Chrysler has the most problems of the ranked brands at 310. Tesla scores 252 but is not ranked because it does not meet the study’s award criteria.
- The study surveyed 30,595 original owners of 2021 model year vehicles after three years of ownership [1].

Notes printed under the chart: Lexus ranks highest among Premium brands, and is noted by a gold bar. Toyota ranks highest among Mass Market brands, and is noted by a gold bar. Brand is not rank eligible because it does not meet study award criteria (Tesla). Source: J.D. Power 2024 U.S. Vehicle Dependability Study. The chart also carries J.D. Power’s statement that rankings are based on numerical scores, and not necessarily on statistical significance.
What the 2024 study found
J.D. Power says owners reported lower dependability than a year earlier, with more problems for nearly two thirds of brands [1]. The rate at which problems grew between 90 days and three years of ownership rose to 17%, from 12% in 2023 [1]. Its senior director of auto benchmarking linked the decline to the difficult period in which these vehicles were built, and noted that the average vehicle on American roads is about 12 years old [1].
- Infotainment was the most problematic category at 49.1 PP100, nearly twice the next category, exterior. Android Auto and Apple CarPlay connectivity (6.3 PP100) and built in voice recognition (6.1 PP100) were the top complaints [1].
- Electrified vehicles had more problems: battery electric vehicles 256 PP100 and plug-in hybrids 216, against 191 for hybrids and 187 for petrol vehicles [1].
- Most improved brands: Porsche (33 PP100 better), Mercedes-Benz (22) and Toyota (21) [1].
- Segment awards: Toyota Motor Corporation won nine model awards (Lexus ES, IS, NX and RX, and Toyota 4Runner, Camry, Corolla, Tacoma and Tundra), General Motors four and BMW two [1].
Among premium brands, Porsche (175) ranked second and BMW (190) third. Among mass market brands, Buick (149) was second, with Chevrolet and MINI tied third at 174 [1].
How the study works
The study, in its 35th year, covers 184 specific problem areas across nine categories: climate, driving assistance, driving experience, exterior, features and controls and displays, infotainment, interior, powertrain and seats [1]. The 2024 survey was fielded from August to November 2023 [1]. Because it asks about three year old cars, the 2024 results describe 2021 model year vehicles, not cars on sale when the study was published.
Notes on this infographic
- Eight brands scored better than the 190 average, three (BMW, Dodge and Jeep) matched it, and 18 scored worse.
- Scores are not necessarily statistically different from each other, as J.D. Power’s own note on the chart says, so brands a few points apart may not differ in a meaningful way.
- PP100 counts problems owners report, which include design and usability complaints such as infotainment, not only breakdowns [1].
Questions about the vehicle dependability study
What are the top 5 most dependable car brands in the 2024 study?
Lexus (135 PP100), Toyota (147), Buick (149), and Chevrolet and MINI tied on 174. Porsche follows at 175 [1].
What car brand has the worst reliability rating in the 2024 study?
Among ranked brands, Chrysler, with 310 problems per 100 vehicles, followed by Audi (275) and Land Rover (268). That is more than double Lexus’s score of 135.
Why is Tesla not ranked in the 2024 vehicle dependability study?
The chart says Tesla is not rank eligible because it does not meet the study’s award criteria. Its score of 252 PP100 is shown separately in grey, and would sit between Lincoln (251) and Volkswagen (267).
