JD Power released its 2026 Vehicle Dependability Study, which highlights an industry-wide rise in reported malfunctions for 2023 model-year cars. The study reveals that modern vehicles are averaging 204 problems per 100 vehicles, an increase of two points over the prior year.
Why it matters
The study identifies the increasing integration of complex electronics and automotive technology as the primary driver behind the rise in vehicle reliability issues. This trend suggests that as cars become more digitized, the frequency of technical problems is expected to climb further.
The study surveyed 33,268 owners across 184 specific reliability points, finding that infotainment systems represent the largest majority of reported malfunctions. Vehicles relying on over-the-air software updates saw a 14% increase in total issues.
The players
JD Power
This global company provides data, analytics, and consumer insights based on independent surveys of product quality and customer satisfaction.
Chevrolet Tahoe
This large SUV model is manufactured by General Motors and is currently available with 5.3-liter and 6.2-liter V8 engine options.
National Highway Traffic Safety Administration
This federal agency is responsible for keeping people safe on America's roadways through the enforcement of vehicle performance standards.
The details
JD Power evaluated nine categories including powertrain, features, and driving assistance to reach their findings. While pure internal combustion engine vehicles ranked at 198 problems per 100, brands like Jeep and Volkswagen ranked higher at 267 and 301 problems respectively.
Timeline
The study evaluated 2023 model-year vehicles.

Roadmap
The rise in reported problems highlights a broader industry shift where increasing vehicle complexity often outpaces traditional mechanical reliability. This positions automakers at a crossroads as they attempt to balance advanced digital capabilities with the durability standards expected by consumers.
Consumers should be aware that highly digitized vehicles with frequent over-the-air updates currently demonstrate a higher likelihood of reported technical issues. Prospective buyers may want to factor these reliability trends into their decision-making process when considering new model-year vehicles.
The takeaway
Vehicle reliability is increasingly defined by software performance rather than just mechanical longevity. Owners should prepare for potential technical troubleshooting and remain informed about manufacturer-issued software updates.
