Aging Vehicles Are Changing the Work Inside Dealership Service Departments

As vehicles stay on the road longer, service departments have an opportunity for more repair business. Capturing that opportunity will require processes built for more complex work.

The vehicles coming into dealership service departments are changing, and MTN is helping dealerships prepare for what that shift means for their technicians, advisors, and customers.

S&P Global Mobility reported that the average U.S. light vehicle reached 12.8 years old in 2025, while the average passenger car reached 14.5 years. S&P also expects vehicles entering the six-to-14-year range to create significant maintenance and repair demand as owners keep them on the road longer.https://www.spglobal.com/automotive-insights/en/blogs/2025/05/average-age-of-vehicle-in-us

On the surface, that sounds like good news for fixed operations. More aging vehicles should mean more service opportunities. But more work does not automatically mean more productive work.

CBT News recently highlighted how older vehicles are bringing more diagnostic and complex repair work into dealership shops. Those jobs can consume significantly more technician time, create backlogs, put pressure on multipoint inspections, and make customer communication more difficult.https://www.cbtnews.com/aging-vehicles-pressure-service-departments/

The challenge for service leaders is recognizing that the mix of work has changed, so the process has to change with it.

Plan Tomorrow's Work Today

A shop built primarily around predictable maintenance can operate differently than one handling a growing number of drivability concerns, electrical problems, intermittent failures, and larger repairs. Service leaders should know before the next morning which vehicles are likely to require significant diagnostic time and which technicians are best equipped to handle them.

That means looking ahead at appointments, identifying potentially complex jobs, protecting diagnostic time, and avoiding schedules that assume every vehicle will move through the shop at roughly the same pace.

The objective is not to slow the shop down. It is to give technicians enough room to solve difficult problems correctly without allowing one complicated repair to disrupt the entire day.

Protect the Multipoint Inspection

When a shop gets backed up, the MPI can easily become one of the first processes to suffer. That is a mistake.

CBT's reporting specifically noted that overloaded technicians may technically complete inspections while the quality of those inspections declines. That can mean missed tire, brake, and maintenance needs that should have been identified.https://www.cbtnews.com/aging-vehicles-pressure-service-departments/

A busy shop needs more process discipline, not less. Service leaders should reinforce what a complete inspection looks like and make sure technicians have enough time to perform it consistently. If the dealership wants customers to trust its recommendations, the inspection cannot become a box that gets checked when the schedule gets difficult.

Make Communication Part of the Repair Process

More complicated repairs also create more complicated conversations.

A service advisor should not have to translate incomplete technician notes into a confident explanation for the customer. Technicians and advisors need a clear handoff process that answers a few basic questions: What did we find? Why does it matter? What does the customer need to see or understand? What happens next?

That communication becomes even more important when the recommendation is expensive or the diagnosis took longer than expected. The technical repair may happen in the shop, but the customer's confidence is often determined by how clearly the dealership explains it.

Video Inspections Matter More as Repairs Become More Complex

This is also where technician video becomes increasingly valuable.

CBT emphasized video MPIs as part of communicating vehicle conditions and recommendations to customers.https://www.cbtnews.com/aging-vehicles-pressure-service-departments/

When customers are being asked to approve a larger or less familiar repair, seeing the condition can make the explanation easier to understand. But simply having video technology is not enough.

The technician still needs a repeatable communication process: show the condition, explain what the customer is seeing, connect it to the recommendation, and communicate professionally and consistently.

That principle is central to the work we do with technicians through MTN PATH. Good video communication is a trained behavior. The camera provides the opportunity for transparency, but the technician determines whether the customer actually understands what they are seeing.

Keep the Customer Ahead of the Delay

Finally, dealerships should reconsider how they communicate when diagnosis takes longer than expected. Customers can usually understand that a difficult repair requires time.

What creates frustration is uncertainty If the shop is backed up, tell them. If diagnosis will continue into the next day, explain why. If additional testing is required, communicate that before the customer has to call asking for an update. Proactive communication does not eliminate the delay, it changes the experience of the delay.

More Opportunity Requires Better Execution

An aging vehicle population creates a meaningful fixed-operations opportunity. S&P Global Mobility's data suggests the demand for maintenance, repairs, and replacement parts should remain substantial as millions of older vehicles stay on the road.https://www.spglobal.com/automotive-insights/en/blogs/2025/05/average-age-of-vehicle-in-us

But dealerships will not capture that opportunity simply by putting more vehicles on the schedule. The service departments positioned to benefit will be the ones that adapt their processes to the work actually entering the shop: plan complex jobs earlier, protect diagnostic time, maintain inspection quality, strengthen technician-to-advisor communication, use video effectively, and keep customers informed.

The vehicles are changing. The service process should change with them.
