Right now, most heavy‐truck maintenance tasks still rely on human skill. The most advanced AI is used for diagnostics and maintenance planning, not for physically doing the work. For example, new scanner tools can read a truck’s computer and use AI to analyze thousands of data points in seconds, spotting likely faults and even suggesting repair steps ^{[1] [1]}.

Fleets also use predictive maintenance systems: sensors and telematics feed data into machine learning models that forecast when parts might fail ^{[1] [2]}. Studies show this can slash downtime and costs, since repairs happen before a breakdown ^{[2] [1]}. In other words, computers help mechanics decide what to fix and when.

Adoption of AI tools in this field will depend on cost, benefits, and trust. For large fleets, the return on investment can be clear: AI-driven maintenance can reduce costly breakdowns and keep big vehicles running longer ^{[2] [1]}. But high-tech systems (sensors, data analysis software, training) can be expensive up front.

Small shops and independent mechanics may adopt new tools more slowly if the cost or training is high. Fundamentally, heavy-vehicle repair is safety-critical and regulated, so any AI tool must prove it really works. Experts warn that AI advice (for example, from chatbots) is sometimes general or uncertain, so technicians still need to double-check recommendations with trusted data or expert judgment ^[4].
