46 SMT007 MAGAZINE I JULY 2026 Throughout this series, we have examined the technologies, materials, architectures, and environmental challenges that influence the reliability of EV electronics. Yet reliability is ultimately judged in only one place: the field. Customers do not experi- ence qualification reports, design reviews, or acceler- ated test results. They experience vehicles that either perform as expected or do not. As EV adoption expands globally, the industry has accumulated a growing body of field experience. These lessons reveal both the strengths of current designs and the areas where improvement remains necessary. They also reinforce an enduring reality of electronics engineering that failures are often the result of multiple contributing factors rather than a single root cause. Design decisions, manufacturing variation, environ- mental exposure, software behavior, and operational stresses can interact over time to produce outcomes that were not fully anticipated during development. 1,2 The good news is that the industry is gaining access to tools, data, and standards that can help identify emerging issues before they become widespread field failures. The challenge is learning how to use them effectively. Failures, Monitoring, and Standards on the Path to EV Reliability ROA D TO R E L I A B I L I T Y BY STA N TO N R A K , S F R A K C O M PA N Y
