Toyota and Lexus swept the 2026 J.D. Power dependability study yet again.

Every year, J.D. Power asks owners of three-year-old vehicles to report every problem they experienced, then tallies the results into one of the industry’s most closely watched dependability rankings. For 2026, the results landed close to where they have landed for years running: Toyota Motor Corporation and its luxury division, Lexus, dominated the list of most dependable models, extending a streak that has become one of the more predictable storylines in the auto industry.

What makes this year’s results notable is not just who won, but how the industry as a whole performed around them. Even as Toyota and Lexus racked up awards, the study recorded the highest number of overall reported problems since its methodology was redesigned in 2022, pointing to a broader dependability slide across most other manufacturers.

A fourth straight year at the top for Lexus

Lexus ranked highest overall among all brands in the study and highest within the luxury segment for the fourth consecutive year, according to Autoblog’s coverage of the results. The Lexus IS took the top spot as the single most dependable model in the entire study, beating out every other vehicle across all categories and price points included in the survey.

Among mass-market, non-luxury brands, Buick claimed the top ranking for a second consecutive year, a result that has become one of the more surprising fixtures of recent J.D. Power studies given the brand’s comparatively modest sales volume in the United States relative to larger competitors.

Eight awards for one automaker

Toyota Motor Corporation, which owns both the Toyota and Lexus brands, collected more individual model-level awards than any other manufacturer in the 2026 study, with eight vehicles recognized as the most dependable in their respective segments. The award-winning lineup spanned Lexus IS, Lexus UX and Lexus GX on the luxury side, alongside Toyota Corolla, Toyota Camry, Toyota Tacoma, Toyota Sienna and Toyota 4Runner on the mainline brand.

That breadth is part of what distinguishes Toyota’s showing from a single standout model elsewhere in the industry. The awards cover compact and midsize sedans, a minivan, a midsize pickup and multiple SUV segments, suggesting the dependability advantage runs through the automaker’s engineering and manufacturing approach broadly rather than being concentrated in one especially well-built vehicle.

How the study actually measures dependability

J.D. Power’s Vehicle Dependability Study surveys original owners of vehicles roughly three years past their initial purchase, capturing problems experienced over that ownership period across 184 specific problem areas grouped into nine major categories: climate, driving assistance, driving experience, exterior, features and controls, infotainment, interior, powertrain and seats. Results are expressed as problems per 100 vehicles, or PP100, giving manufacturers a standardized score that can be compared across brands and against prior years.

Now in its 37th year, the study has become one of the most cited dependability benchmarks in the industry precisely because of its methodology: it measures real-world experience reported directly by long-term owners, rather than relying on predicted reliability estimates or manufacturer-supplied warranty data, giving it a somewhat different lens than competing studies from outlets like Consumer Reports.

An industry-wide dependability slide

The headline result for Toyota and Lexus sits alongside a less flattering trend for the industry overall. According to J.D. Power’s own release of the 2026 results, vehicles across the industry recorded their highest overall problem rates since the study’s redesign in 2022, with the industry average rising to 204 problems per 100 vehicles, an increase of two PP100 compared with the 2025 results.

That upward trend has been building for several years and has been linked by industry analysts to a combination of factors, including the rapid expansion of complex infotainment and driver-assistance technology, which introduces more potential failure points than traditional mechanical systems, along with software and technology integration challenges that have proven harder for some manufacturers to iron out than legacy hardware problems.

Why Toyota and Lexus keep beating that trend

Toyota’s continued strength inside a generally declining industry dependability picture reinforces a pattern that has shown up consistently across independent studies for years: a conservative approach to introducing new technology, extensive pre-release testing and a preference for proven components over unproven ones. Where some competitors have pushed more aggressively into complex new infotainment systems and driver-assistance features that can introduce new problem categories, Toyota and Lexus models have generally rolled out comparable technology more gradually, giving engineering teams more time to work out issues before they reach large numbers of owners.

That approach has costs of its own, including a reputation in some circles for slower feature rollouts compared with more technology-forward competitors. But for buyers prioritizing long-term dependability over the newest available features, the 2026 results extend a now well-established pattern: when it comes to owner-reported problems after three years on the road, Toyota and Lexus remain difficult for the rest of the industry to catch.

How other manufacturers fared

Beyond the Toyota-Lexus sweep at the top, the 2026 study highlighted a wider spread of performance across the rest of the industry, with several mainstream brands showing meaningful year-over-year improvement even as the overall industry average worsened. Buick’s continued strength among mass-market brands stood out as one of the more consistent storylines outside the Toyota ecosystem, suggesting that dependability leadership in this year’s results was not confined to a single automaker’s approach to engineering and manufacturing.

Luxury brands generally posted higher problem rates than mass-market brands across the study, a pattern that has held for several consecutive years and is often attributed to the greater technological complexity built into higher-end vehicles, including more extensive driver-assistance suites, larger and more feature-dense infotainment systems, and additional comfort technology that introduces more potential points of failure than a comparably priced mainstream vehicle.

What the results mean for shoppers

For buyers using dependability data to inform a purchase decision, the 2026 study reinforces a now-familiar shopping heuristic: Toyota and Lexus models remain a comparatively low-risk choice for buyers prioritizing fewer post-purchase problems, while shoppers considering brands further down the rankings may want to weigh dependability data alongside other factors like technology features, driving dynamics and purchase price, since the industry-wide problem-rate increase suggests dependability gaps between brands are, if anything, widening rather than narrowing this year.
