Modern vehicles are packed with technology, from touchscreens and sensors to wireless updates. However, a recent study from JD Power reveals that as cars become smarter, their dependability is declining.
Dependability Declines
The latest JD Power Vehicle Dependability Study, surveying 33,268 owners of 2023 vehicles, shows a worsening trend. Problems rose by 2 per 100 vehicles compared to the previous year, bringing the industry average to 204 problems per 100 vehicles (PP100). This is the highest rate since 2022, extending a three-year decline in long-term reliability.
The problem isn’t mechanical breakdown, it’s software and connectivity. This is new; cars used to fail due to failing parts. Now, they fail because of bugs, glitches, and updates gone wrong.
Infotainment Systems Drive Complaints
Infotainment systems are the primary source of frustration, generating 56.7 PP100. The biggest headaches involve smartphone integration, with Apple CarPlay and Android Auto connectivity issues leading at 8.9 PP100. Bluetooth and wireless charging also contribute significantly to complaints.
This matters because drivers expect seamless tech integration. Modern cars are designed around the smartphone experience; when that fails, it ruins the entire driving experience.
Over-the-Air Updates Underperform
Over-the-air (OTA) software updates promise improvement, but the study shows they often fall short. Only 27% of respondents noticed a positive change after an update, while 58% reported no difference. Vehicles receiving OTA updates actually showed more problems.
The disconnect between promise and reality is damaging trust. Owners are skeptical of updates if they don’t deliver tangible benefits.
Powertrain Reliability: Hybrids Struggle
Plug-in hybrids are the least reliable powertrain type, with 281 PP100, up 39 from last year. Electric and hybrid vehicles also saw increases (14 PP100 each), while traditional gas engines improved slightly to 198 PP100.
The transition to electrified vehicles is exposing new failure points. While gas engines are mature, hybrid and EV technology is still evolving, and owners are paying the price.
Top Performers and Worst Offenders
Lexus ranked highest in dependability with 151 PP100, well below the industry average. The Lexus IS was the single most reliable vehicle. Other strong performers included Honda Civic, Kia Forte, and Toyota Camry.
At the bottom, VW, Volvo, Land Rover, Tesla, and Mercedes-Benz all recorded higher issue rates. Premium brands overall underperformed mass-market brands, reversing a recent trend.
Brand reputation isn’t always a guarantee of reliability. Luxury vehicles aren’t necessarily more dependable; in some cases, they are far worse.
The core takeaway is clear: modern cars have become too complex. The relentless push for features and connectivity has come at the cost of dependability. Drivers want reliable transportation, not another software beta test.
