Vehicle reliability drops as tech problems increase in 2026

The latest J.D. Power 2026 U.S. Vehicle Dependability Study reveals that despite technological advances, vehicle reliability is declining. The average score worsened from 202 to 204 problems per 100 vehicles, marking the highest figure since the methodology was updated in 2022. The main trouble spots are electronics, multimedia systems, and software.

The study highlights that over-the-air updates, intended as a convenient way to maintain functionality, have contributed nearly 14% of new issues to the industry. Meanwhile, 58% of owners reported no noticeable benefit from these updates. Technological complexity is outpacing the infrastructure and integration quality needed to support it.

Smartphone connectivity services have become one of the market's biggest pain points. Out of the five key problem areas in the study, four relate to the link between cars and phones. Android Auto, Apple CarPlay, Bluetooth, wireless charging, and proprietary apps collectively account for 24.2 problems per 100 vehicles—nearly half of all multimedia malfunctions.

The premium segment isn't faring much better. Its problem count increased by 8 PP100 over the year, the sharpest rise since 2022. The gap between mass-market and luxury models is widening: premium vehicles struggle more with control ergonomics and overall user experience, though they still outperform mainstream models in powertrains and seating.

A significant reliability drop is noted for hybrids and plug-in hybrids. Plug-in hybrids emerged as the most problematic category, with an increase of 39 PP100. They are followed by electric vehicles and conventional hybrids, while gasoline models show slight improvement.

The report delivers a clear conclusion: technological sophistication is outpacing implementation quality. If the industry doesn't adapt its approach to electronics development, the reliability crisis will deepen as digital features expand.
