Predictive maintenance is not enough, says CEO
Detroit, MI, USA – April 16th, 2026 — Questar Auto Technologies, specializing in highly advanced fleet health management powered by its exclusive 5 stack AI architecture, today announces that its Total Fleet Health solution is being released worldwide. Already renowned for providing fleets with actionable recommendations and substantial cost savings, the newest version of Total Fleet Health delivers expanded precision and accuracy as well as new features in a fully proactive process based on deep AI intelligence. Total Fleet Health integrates with any existing telematics platforms.
Questar’s enhanced AI models deliver accurate root cause analysis, early fault detection, and high-confidence predictions of what is likely to fail and when. Each vehicle receives a dynamic health score that continuously updates based on real-time data, fault history, and predictive models. Fleet managers instantly see which vehicles are healthy, which need attention, and which are approaching critical thresholds, turning complex diagnostics into a single, actionable metric.
What’s New:
A new, embedded AI Assistant lets every stakeholder explore fleet data in natural language – no technical expertise required. Maintenance managers can ask which vehicles need immediate attention; finance teams can query the total cost burden of open alerts; and operations can surface the most common recurring faults across the fleet.
A new predictive ranking flags vehicle most likely to experience a breakdown or critical failure. By scoring each vehicle’s risk of deterioration, fleet managers can prioritize repairs before a minor issue becomes an unplanned roadside event.
Also new, the estimated cost of ignoring calculates the estimated financial impact of delaying repair, giving decision-makers a clear, dollar-based reason to act now rather than later.
The ability of the Total Fleet Health solution to assess any vehicle’s condition with very high accuracy is derived from its exhaustive data along with critical context gained from patterns and trends the solution identifies across the entire fleet. Questar continuously learns from these vast streams of vehicle and operational data to anticipate issues before they occur and recommends the best actions to resolve them.
“We are living in an era where AI can truly transform the way fleets maintain vehicles,” says Questar CEO Vered Mandelboum Josef. “Questar’s technology supports fleet managers every step of the way – from understanding what happened to seeing what is going on right now, anticipating what is likely to happen next, and ultimately, what to do about it; all in clear, actionable language.”
Josef further explains thatpriority is defined by the risk of deterioration and the estimated cost of ignoring it – so fleet managers can make confident, data-driven decisions and act before small issues become costly failures.
“That’s how you move from reactive maintenance to truly proactive fleet health management,” Josef says. “Predictive maintenance is not enough.”
The newest version of the Questar vehicle health management solution is available C2C or with Questar telematic hardware. It can also be integrated with existing telematics platforms. New North American partnerships include Atmus’ Fleetguard subsidiary and Geotab.
Accessible to all Stakeholders
Questar engages stakeholders in a highly responsive and easy-to-use environment; accessible to not just maintenance but to all permitted users including management, finance, and operations. The solution communicates in natural, everyday language with everyone.
Powerful Insight
The Total Fleet Health product design, including Questar’s patent pending foundations, captures the most comprehensive historical and real time data on individual vehicles to assess health with unparalleled, granular insight. This results in:
– proactive, early insights
– root cause analysis
– risk of mechanical deterioration
– instructions for repair
– cost estimates of delaying repair
“Rather than reacting to isolated fault codes,” Josef says, “Questar applies data-driven prediction models to calculate failure probability and estimated cost of inaction, giving fleets foresight into what is likely to fail and when.”
