Every year, millions of components move through Indian workshops as vehicles age, break down, from brake pads and filters to batteries, sensors, and body panels. Owners pay a premium for genuine replacements because they want their vehicle to stay safe, reliable, and covered under warranty. Yet once a technician closes the hood, there is rarely any way for that owner to confirm the part actually installed is the part they paid for. This gap in certainty reaches far beyond the immediate risk of a fake product. It touches on the quality of the service data recorded against that vehicle, the warranty decisions an OEM will eventually have to make, the visibility manufacturers have into a component’s life on the road, the accuracy of predictive maintenance models trained on that data, and how confident an owner feels about the vehicle itself.

The scale of the underlying problem is not abstract. ACMA’s review of FY25 put the country’s auto component domestic aftermarket alone at reaching USD 11.8 billion. Counterfeit parts have already captured a significant share of the market, with ASSOCHAM estimates showing that roughly one in three auto parts sold in India is not genuine. The impact extends beyond the market itself to consumer confidence. ASPA and CRISIL’s State of Counterfeiting in India 2025 report, released this year, reports 22 percent of consumers surveyed had identified counterfeit automotive parts in the vehicle replacement market, underscoring how common such encounters have become and how it’s leading to loss of consumer confidence while diverting revenue away from legitimate manufacturers and channel partners..FICCI CASCADE has linked roughly 20 percent of road accidents in India to counterfeit auto parts, which turns auto parts counterfeiting from a commercial nuisance into a major public safety concern.

None of this is an argument against independent repair. Customers have earned the freedom to service their vehicles wherever they choose, at an authorized dealership, a neighborhood garage, or anywhere in between. The issue was never where a vehicle gets serviced. The issue is whether the customer receives the genuine component they paid for. Picture someone who pays a premium price for what is represented as a genuine replacement part for their prized vehicle. The packaging looks right. The invoice reflects accurate pricing. However, if the part underneath the packaging is counterfeit, the customer loses more than money. They lose confidence in the vehicle, the workshop, and eventually the brand whose name was printed on a box that never held a genuine product. Every customer deserves the same certainty about what sits inside their vehicle, regardless of where they choose to have it serviced or where they buy whether it’s e-commerce or distributors.

This is where authentication needs to be understood differently. We have long treated it as a narrow anti-counterfeiting tool, something added to packaging to catch fakes at the point of sale. That framing undersells what verified component identity can do. Built into a digital platform, authentication becomes part of the vehicle’s own digital identity, alongside its service records, ownership history, and diagnostic data. A verified component can enable a trusted service history that follows the vehicle rather than the workshop. It can enable accurate warranty validation instead of disputes built on guesswork. It can enable recalls that reach the exact vehicles carrying an affected part instead of blanket notices sent across an entire model line. As vehicles become more connected and software-defined,the ability to verify the identity of every critical component becomes fundamental to safe servicing, accurate recalls, and reliable vehicle data.

QR codes, holograms, serial numbers, and tamper-evident packaging were all designed for an earlier generation of counterfeiting, when a fake label or a scannable code created enough friction to stop most casual buyers. Counterfeiters have since caught up. Codes get copied along with the packaging around them. Holograms get replicated at scale. What the modern aftermarket needs is an anti-counterfeiting solution for autoparts built on identity that is physically unclonable, independently verifiable by anyone and anytime in the supply chain, rather than only by the brand that issued it. That shift, from visible deterrents to structural, unclonable verifiable identity, is becoming essential rather than optional.

The commercial case for making that shift keeps strengthening. OEMs that lean into aftermarket sales and services rather than treating them as an afterthought have recorded profit margins up to four times higher than new unit sales, and roughly double the total shareholder returns of OEMs that underinvest in service. India‘s active vehicle base, currently around 333 million units, is projected to reach approx. 430 million by 2030 (source:mckinsey), pushing the domestic aftermarket toward USD 16 billion at a 6 to 7 percent CAGR. Capturing that value takes more than parts availability. It takes customers who trust the ownership experience enough to stay engaged, and 76 percent of vehicle and mobility service customers (source: capgemini) already expect the same seamless, end-to-end experience they receive from other industries. Remote diagnostics, fleet uptime monitoring, and subscription-based service offerings all depend on that same underlying trust. None of it works if the brand cannot say with certainty what is inside the vehicle it is servicing.

That certainty matters most where the industry is placing its biggest bets, in predictive maintenance, artificial intelligence, and telematics. Predictive servicing assumes the system knows exactly which component is operating inside a given vehicle. Introduce a counterfeit brake pad, an unapproved filter, or an incompatible sensor into that picture, and the assumption breaks. Diagnostics built on unreliable inputs produce unreliable outputs. Warranty decisions become harder to defend. Predictive models trained to estimate a component’s remaining useful life end up estimating the life of a part that was never installed. McKinsey’s research on connected vehicle data found that predictive maintenance can reduce downtime by 30 to 50 percent, extend equipment life by 20 to 40 percent, and cut maintenance costs by 15 to 30 percent, but only when the underlying data can be trusted. Authentication and traceability make that trust possible at the component level, linking every data point back to a verified part rather than an assumed one.

Authentication, then, is evolving into something closer to connective tissue than a checkpoint. Supported by traceability and a genuine digital identity for every component, it strengthens ownership experiences, protects brand loyalty earned over decades, sharpens warranty management, and gives predictive systems the reliable foundation they need. As an industry, we have spent years optimizing what happens after a vehicle is sold. The next stage of that work depends on something more basic: knowing, with certainty, what is actually inside the vehicle. The leaders who treat that certainty as core infrastructure, rather than a line item under compliance, will define what trust means for the next decade of automotive ownership.
