Smarter Cars, More Problems: Tech Glitches Drive Vehicle Dependability Down

TROY, Mich. – February 12, 2026 – By Melissa Adams

Modern vehicles, running on more lines of code than early spacecraft, are facing a crisis of confidence. A landmark study released today reveals that the very technology intended to enhance the driving experience is becoming a primary source of owner frustration, driving long-term vehicle dependability to its lowest point in years.

The J.D. Power 2026 U.S. Vehicle Dependability Study (VDS) found that problems reported by original owners after three years have climbed to a new high, with an industry average of 204 problems per 100 vehicles (PP100). This marks a steady decline in reliability over the last three years and underscores a growing paradox: as cars get smarter, they are also becoming more prone to glitches, bugs, and failures that are eroding owner satisfaction.

The Tech Headache: When Innovation Becomes Annoyance

At the heart of the issue are the complex digital systems now central to the modern car. For the fourth consecutive year, the infotainment category—encompassing navigation, media, and smartphone integration—remains the most problematic area for owners, accounting for a staggering 56.7 PP100, more than double the next-highest category, vehicle exterior.

Four of the top five most-reported problems industry-wide are directly tied to integrating mobile phones. The top complaint, for the third year running, is faulty connectivity with Android Auto and Apple CarPlay (8.9 PP100). This is compounded by issues with built-in Bluetooth systems (5.5 PP100), unreliable wireless charging pads (5.1 PP100), and buggy manufacturer-developed mobile apps (4.7 PP100). These connectivity headaches alone make up nearly half of all infotainment-related complaints, a sentiment widely echoed in consumer forums and other industry surveys which consistently highlight buggy software as a top grievance.

Over-the-air (OTA) software updates, once hailed as a revolutionary way to improve vehicles post-purchase, are also delivering mixed results. While now a routine experience for 40% of owners, their value is being questioned. A striking 58% of owners who received an update reported no noticeable difference in their vehicle’s performance, and only 27% felt the update provided a tangible improvement. More concerning, updates delivered OTA were associated with a nearly 14% increase in reported problems, suggesting that some fixes may be introducing new issues.

“As owners hold onto their vehicles longer, the long-term ownership experience matters more than ever," said Jason Norton, director of auto benchmarking at J.D. Power. "Software updates and new technologies should enhance the ownership experience over time, yet many vehicle owners cite ongoing mobile phone integration problems and little to no benefit after an update is performed. Automakers should focus on delivering meaningful improvements and clearly communicating the intended benefits."

A Widening Gap Between Brands and Powertrains

The study also reveals a growing divide in the market. Premium brands, often pioneers in deploying advanced technology, are struggling more than their mass-market counterparts. Problems in the premium segment jumped by 8 PP100 to an average of 217 PP100, widening the dependability gap with mass-market vehicles (200 PP100) to its largest point since 2022. Premium vehicles now underperform in seven of the nine categories measured, including features/controls/displays and overall driving experience.

Perhaps most alarmingly for the future of the industry, the study highlights a significant reliability gap for electrified vehicles. While gasoline-powered cars saw a slight improvement in dependability (198 PP100), all electrified powertrains reported more problems. Hybrids came in at 213 PP100, while battery-electric vehicles (BEVs) averaged 237 PP100. Plug-in hybrid electric vehicles (PHEVs) were the most problematic of all, with a dismal 281 PP100, a sharp increase of 39 problems from the previous year. This trend could pose a significant headwind to broader EV adoption, as mainstream consumers who prioritize reliability may hesitate to switch from proven gasoline technology.

Industry at a Crossroads: Leaders and Laggards

Despite the industry-wide decline, some brands have managed to navigate the turbulent tech landscape successfully. For the fourth consecutive year, Lexus ranked highest in overall dependability among premium brands with a score of 151 PP100. It was followed by Cadillac (175 PP100) and Porsche (182 PP100). In the mass-market segment, Buick led for the second year in a row with a score of 160 PP100, with MINI (168 PP100) and Chevrolet (178 PP100) also performing strongly.

Toyota Motor Corporation and General Motors Company demonstrated that combining technology with reliability is achievable, securing the most model-level awards. Toyota received eight awards for models including the Lexus IS, Toyota Corolla, and Toyota Tacoma, while GM earned four for vehicles like the Buick Enclave and Chevrolet Tahoe. The success of these brands suggests that a disciplined approach to engineering and technology integration can mitigate the problems plaguing the rest of the industry.

A Call for Faster Fixes and Better Communication

Recognizing that the traditional annual study cycle may be too slow to address the fast-moving world of software, J.D. Power announced significant changes to its methodology for the 2027 study. By implementing year-round data collection, continuous reporting, and integrating verified repair data, the firm aims to provide automakers with more immediate and actionable insights.

This shift reflects the urgent need for the industry to adapt. As vehicles become increasingly defined by their software, automakers are no longer just metal-benders; they are technology companies. The findings of the 2026 VDS serve as a clear warning that mastering the art of software development and ensuring its reliability is no longer optional—it is fundamental to building customer trust and securing long-term loyalty in an ever-more-connected world.
