Automotive OEMs Are Extending Product Lifecycles. Manufacturing Strategy Is Changing With It.
Automotive OEMs are rethinking manufacturing strategy as vehicles remain on the road longer, aftermarket demand grows, and uncertainty continues to reshape the industry.
For years, production planning was largely driven by new vehicle launches and high-volume manufacturing programs. Today, the market looks different. Consumers and fleets are holding onto vehicles longer, replacement cycles are extending, and OEMs are balancing electrification, connected systems, supply chain pressure, tariffs, and changing customer expectations all at once.
As a result, lifecycle support is becoming far more strategic. OEMs are no longer focused only on how quickly they can launch a program. Increasingly, they also need to think about how they will support, adapt, and sustain that product years after launch.
Longer Vehicle Lifecycles Are Reshaping Manufacturing
One of the clearest indicators is the age of vehicles currently in operation.
According to S&P Global Mobility, the average age of light vehicles in the U.S. reached 12.8 years in 2025, continuing a steady upward trend driven by higher vehicle costs, improved durability, and economic pressure. That trend is having a direct impact on manufacturing strategy. Older vehicles create growing demand for replacement electronics, service parts, upgrades, repair programs, and sustaining production support. In many cases, OEMs are supporting platforms much longer than originally expected.
The aftermarket is growing alongside that shift. The Auto Care Association and MEMA Aftermarket Suppliers reported that U.S. light-duty aftermarket sales reached $413.7 billion in 2024, with continued growth projected through 2028.
For OEMs, this is no longer just a service opportunity. It is becoming an operational and manufacturing challenge.
The Aftermarket Is Becoming More Strategic
Traditionally, aftermarket support operated separately from core production strategy. However, many OEMs are now treating it as a critical growth area.
Syncron’s 2025 aftermarket research found that 80% of OEM leaders plan to increase aftermarket investment over the next five years, while nearly half already consider it a top strategic priority.
This shift changes how companies think about sourcing, production planning, and supplier relationships. Supporting products over a longer lifecycle requires better forecasting, stronger supply continuity, and the ability to manufacture or source components well after peak production has ended.
For electronics manufacturing, that creates additional complexity. Modern automotive platforms increasingly rely on sensors, communication modules, embedded systems, displays, and power electronics. As these systems age, OEMs face growing pressure around component obsolescence, software updates, cybersecurity requirements, and long-term reliability.
At the same time, connected systems continue to expand across automotive platforms. Frost & Sullivan’s 2026 analysis of North American automotive OEMs highlights continued investment in connected services, software-enabled platforms, AI-driven features, diagnostics, and cloud ecosystems.
This means OEMs are no longer supporting only the mechanical life of the vehicle. They are supporting electronics, data infrastructure, and connected systems over a much longer operating lifecycle.

OEMs Are Managing “Stacked Uncertainty”
Another major challenge is the amount of uncertainty OEMs are navigating simultaneously. Ihe industry is often described as operating in an era of “stacked uncertainty,” driven by supply chain disruption, changing regulations, electrification, tariffs, and shifting demand.
That pressure is forcing manufacturers to rethink how flexible and resilient their operations really are. A manufacturing model optimized only for high-volume efficiency may struggle when demand fluctuates, parts become difficult to source, or programs require lower-volume sustaining production years after launch.
As a result, OEMs are placing greater value on manufacturing flexibility, responsiveness, and long-term operational support.
Manufacturing Strategy Is Moving Beyond Launch
The manufacturing conversation is changing from:
“How fast can we ramp production?”
to:
“How reliably can we support this product over time?”
OEMs increasingly need manufacturing partners that can:
- support low-to-mid volume production
- adapt to changing demand
- manage supply chain variability
- support legacy electronics and replacement assemblies
- maintain quality across long lifecycle programs
This is especially important in electronics manufacturing, where component lifecycles are often shorter than the products they support.
Cost still matters, but risk is becoming part of the cost equation. A lower-cost supplier provides little advantage if supply disruptions, obsolescence issues, or inflexible production models create delays later in the program lifecycle.
That is why many OEMs are shifting toward manufacturing strategies that prioritize resilience alongside cost competitiveness.
Supporting Automotive Programs
At DSM, we see these industry changes through the lens of electronics manufacturing and long-term customer partnerships.
As automotive and mobility OEMs extend product lifecycles, they increasingly need manufacturing partners that can combine technical sophistication, operational flexibility, and cost competitiveness while supporting programs beyond the initial launch phase.
DSM supports customers across PCB assembly, box build, system integration, testing, inspection, conformal coating, repair, and lifecycle support throughout Canada and the U.S. More importantly, our approach is built around adaptability and long-term collaboration rather than transactional production alone.
As manufacturing priorities continue to evolve, OEMs will need partners that can help manage complexity, respond to change, and support products throughout their full lifecycle.
Automotive OEMs are extending product lifecycles. Manufacturing strategy is changing with it. Companies that adapt early will be better positioned to reduce risk, maintain continuity, and support customers in an increasingly complex market.
