New TOPDON Survey Sheds Light on U.S. Automotive Repair, Highlights Industry Shifts and Key Insights of Professional Technicians, DIY Mechanics

TOPDON US recently released the results of a national survey of more than 3,000 professional automotive technicians and DIY mechanics across North America. Conducted in September 2025, the survey highlights the repair challenges facing technicians in the age of advanced vehicle technology, as well as key shifts in the adoption of diagnostic tools that support integrated, platform-based workflows.

Of all respondents, 47% identified as professional technicians and 53% identified as DIY mechanics.

“Our survey goal was to better understand the customers we serve and secure clear, actionable data that can help us meet their needs in a rapidly changing industry,” said Chad Schnitz, Vice President of TOPDON US. “Among the key takeaways is that despite decades of experience among our professional respondents, 73% cited limited OE data access and other digital restrictions—not lack of skill—as their biggest challenge.”

Professional Technician Survey Results

Among professional technicians surveyed, 66% reported having more than 10 years of experience, and 51% indicated they hold ASE certification.

When asked about their biggest diagnostic challenges:

• 73% cited limited OE data access
• 67% identified vehicle network communication systems as difficult to diagnose
• 39% reported challenges working with EV and hybrid battery systems, inverters, and isolation faults
• 33% pointed to ADAS as a growing source of complexity

“The biggest obstacles that professional mechanics face parallel the features and functions they want in their diagnostic tools,” Schnitz said. “For example, 68% cited a need for more in-depth OEM-level diagnostics and coverage. Additionally, 46% want wiring diagrams and guided repair steps, and 45% would like faster scan speeds.”

Survey results also showed a shift in how technicians evaluate diagnostic tools. While price has historically been a major factor, respondents indicated that accuracy and ease of use are now the top priorities. In addition, 77% reported learning about new diagnostic tools through YouTube, while 57% rely on manufacturer websites.

When asked about broader industry trends, 81% of respondents pointed to increased use of OEM-secured gateways and encrypted vehicle systems. Another 55% cited the growth of EV and hybrid vehicles as a major factor shaping the future of diagnostics.

DIY Mechanic Survey Results

The increasing complexity of modern vehicles is also influencing DIY repair behavior and contributing to the rise of the “prosumer” mechanic.

Among DIY respondents:

• 85% reported using diagnostic tools to determine whether they can complete repairs themselves
• 81% cited reading and clearing trouble codes as their primary use case
• 60% said they use diagnostic tools to avoid unnecessary repair costs at service shops

Nearly 90% reported engine diagnostics, oil changes and fluids, brake and rotor repair, and electrical or battery-related work as their most common repair activities.

However, only 49% said they currently use a full-featured scan tool. Many cited limited support resources or unclear next steps after retrieving a fault code as their biggest frustration.

“Similar to professional technicians, our survey found that 74% of DIY mechanics cited features and functions as the most important factor when shopping for a diagnostic tool,” Schnitz said. “We also found that features outrank both brand reputation and price. This means the tool market is shifting from legacy loyalty to merit-based trust in product capability.”

The Road Ahead

TOPDON’s survey results suggest that vehicle diagnostics are evolving from fragmented tools toward integrated, data-driven repair platforms.

“The data from our survey makes one thing very clear—the future of automotive diagnostics depends on access, education, and adaptability,” Schnitz said. “These are all at the core of TOPDON’s mission.”
