J.D. Power’s 2024 vehicle dependability study highlights Toyota and Lexus as most reliable, with EVs improving but plug-in hybrids having more issues. Get key insights and rankings.
J.D. Power has released its annual vehicle dependability study, focusing on cars up to three years old. Amid a general rise in reported issues, Toyota and its premium brand Lexus have reinforced their reputations as some of the most reliable manufacturers, while Volkswagen, Volvo, and Land Rover found themselves among the laggards.
The average number of problems per 100 vehicles climbed to 204 points—the highest since 2022. The premium segment showed particularly negative trends, reaching 217 points. Analysts note that luxury brands are increasingly underperforming compared to mass-market ones.
Lexus secured the top spot among premium brands for the fourth consecutive year with a score of 151 points. It was followed by Cadillac (175 points) and Porsche (182). In the mass-market category, Buick led with 160 points, ahead of Mini (168) and Chevrolet (178).
Toyota placed eighth overall with 185 points but stood out for having the most models ranked best in their classes: the Lexus IS, UX, and GX, along with the Toyota Corolla, Camry, Tacoma, and 4Runner.
GM also performed well, with four of its models—the Buick Enclave, Cadillac XT6, Chevrolet Equinox, and Tahoe—earning segment awards.
Plug-in hybrids proved the most problematic, averaging 281 points. Electric vehicles improved to 237 points, while gasoline-powered cars became more reliable, lowering their issue rate to 198 points.
