Do you believe that increasing vehicle technology makes your car less reliable?
The 2026 Vehicle Dependability Study from JD Power reveals that vehicle issues have risen to an average of 204 problems per 100 vehicles. This annual survey of 33,268 owners of 2023 model-year cars indicates that technology-heavy features, particularly infotainment systems, are the primary drivers of these reliability gaps.
Why it matters
As modern vehicles integrate more complex software and electronics, owners are seeing an increase in mechanical and digital malfunctions that can affect long-term maintenance costs and vehicle usability. This trend suggests that higher tech density in newer models often correlates with more frequent service visits.
The study tracked 184 unique reliability points across 33,268 vehicle owners. While pure internal combustion engines averaged 198 problems per 100 vehicles, those with over-the-air update capabilities saw a 14% increase in reported issues.
The players
JD Power
A global consumer intelligence firm that tracks vehicle quality and reliability through annual owner surveys.
Chevrolet Tahoe
A large SUV model featuring V8 engine options that earned top marks in its segment despite broader industry reliability trends.
National Highway Traffic Safety Administration
The federal agency tasked with investigating safety-related defects in motor vehicles, including specific engine component failures.
Jeep
An automotive brand that recorded 267 problems per 100 vehicles in the latest industry rankings.
Volkswagen
An automotive manufacturer that recorded 301 problems per 100 vehicles in the study.
The details
JD Power evaluates dependability by surveying owners about nine distinct categories including climate control, driving assistance, and powertrain components. Infotainment systems consistently record the highest volume of malfunctions, accounting for 56.7 problems per 100 vehicles. Additionally, complex systems like the 6.2-liter V8 engine found in the Chevrolet Tahoe remain under NHTSA investigation for specific lubrication and component failure concerns.

The Home Front
The rising frequency of vehicle problems aligns with the industry-wide shift toward high-tech infotainment and software-dependent features. This trend challenges previous expectations of long-term vehicle reliability as manufacturers prioritize advanced digital capabilities over simple mechanical design.
If you own a 2023 model-year vehicle, check your owner portal for any available software patches that may address reported infotainment glitches. Owners should also review their maintenance schedule, as complex engine systems like those in larger SUVs may require professional inspection to avoid potential component failures.
The takeaway
Vehicle reliability is increasingly tethered to electronic stability rather than just mechanical performance. To manage these risks, keep a detailed record of all software updates performed at the dealership and consult a licensed professional if you notice persistent performance lag.
