Connected Cars: The Digital Nervous System Changing Repair

by Chasidy Rae Sisk

The automotive and collision repair industries have weathered aluminum, high-strength steel, electrification and ADAS. Shops have adapted, invested and trained. But the next disruption isn’t bolted to the frame rail – it’s invisible.

“The connected car is the next big disrupter that is going to change the landscape of collisions and what mechanics are working on,” says AASP Executive Director Linden Wicklund. She’s right, yet most of the industry still doesn’t fully understand why.

Today’s automobile is no longer simple transportation; it’s a rolling data center capable of bidirectional communication with manufacturers, infrastructure, other vehicles and sometimes even insurance carriers. It can collect up to 25 gigabytes of data per hour — geolocation, speed, braking patterns, camera feeds, biometric inputs and even cabin activity in some cases. And that data doesn’t just stay in the car…it often streams directly to the OEM, and that changes everything.

So, what does “connected” really mean? Many people envision this as nothing more than connecting their phone to their vehicle via Bluetooth, yet connectivity goes far beyond streaming music or real-time traffic.

Modern vehicles use cellular telematics and, in some cases, dedicated short-range communications operating in the FCC-granted 5.9 GHz spectrum to enable vehicle-to-everything (V2X) communication. Autonomous driving – even in its current partial forms – doesn’t function without this digital handshake between car and cloud.

But here’s the part that matters most to repairers: connectivity shifts diagnostics and service alerts away from the OBD-II port and into manufacturer-controlled ecosystems.

For decades, the OBD-II port leveled the playing field. Independents could plug in, scan, diagnose and compete.

Now, the vehicle may detect a failing module and transmit that data wirelessly to the OEM before the driver ever sees a warning light. The dealership gets the alert, the appointment gets scheduled, and the consumer never even contemplates where they’re going to take their vehicle to be repaired. Is this a savvy business model or outright steering?

Fears related to this have shifted the Right to Repair debate from service manuals and scan tools to server access, subscription paywalls and whether independent shops can afford OEM-level credentials.

Organizations like the Auto Care Association have warned that wireless telematics could create a closed-loop system where data flows exclusively to manufacturers. Their position is simple: whoever controls the data controls the repair.

Some argue — including voices within Society of Collision Repair Specialists (SCRS) — that shops already have full access to necessary data through OEM subscriptions, and while that’s technically true, it doesn’t always translate to practical application due to the high subscription costs, proprietary software, required hardware, bandwidth demands and ongoing calibration investments which create financial barriers that small and mid-sized independent facilities simply can’t absorb.

Access behind a paywall isn’t equal access. And when data bypasses the physical vehicle entirely, even the best aftermarket scan tool can’t retrieve what it never receives.

In early 2025, SCRS, the Automotive Service Association and the Alliance for Automotive Innovation proposed new federal legislation to address some of these concerns. Building upon a 2023 Right to Repair agreement with vehicle manufacturers, the Safety as First Emphasis (SAFE) Repair Act adds further safeguards for consumers by ensuring “consumers and independent repair shops have the data they need to repair their vehicles,” “ensuring consumers retain the right to decide where and how their vehicles are repaired” and “guaranteeing that repairs are performed in accordance with manufacturer-produced repair procedures to restore vehicle safety systems and structural integrity,” according to a joint letter submitted by those three organizations to members of Congress.

Vehicle repair has always been about safety. But while safety used to merely mean weld integrity and structural measurements, it now includes software calibration, firmware updates and cybersecurity awareness.

Complicated ADAS installed in modern vehicles rely on precise camera, radar and sensor calibration, and a missed step doesn’t just affect performance – it affects liability. And now, with connected vehicles, repair facilities interact with mobile networks, internal vehicle servers and cloud-based systems, creating the potential for even greater liability; it’s entirely plausible that a repair facility could be drawn into litigation if a connected vehicle is hacked or compromised in some way.

A repair is no longer a mere matter of wrench work. It now requires a clearer understanding of the digital infrastructure of these vehicles.

And as vehicles collect a greater array of consumers’ vehicle data (including location tracking and driving behavior), repair shops find themselves in custody of sensitive information, creating an expansion of the technician’s role.

Here’s the uncomfortable truth: connected vehicles favor larger organizations like MSOs which can spread subscription costs and other investments across multiple locations. For a single-location independent, those costs have a different impact. And if the vehicle itself is programmed to communicate primarily with OEM networks, the independent shop starts the race a lap behind.

Although consumers may not realize they’re being digitally steered, they will feel the price tag when dealership service becomes the default. That’s why the conversation around telematics access matters. Not just for shop survival – but for market competition and consumer choice.

There are pros and cons to just about every new technology that makes its way onto the market. By introducing predictive maintenance capabilities, connected vehicles can trigger proactive service scheduling for brake pads, batteries and system faults, creating efficiency and fewer roadside breakdowns. But at the same time, if the OEM controls the alert, they control the appointment funnel.

Independent shops must find ways to stay visible in a predictive world by investing in training, leveraging customer education and advocating for legislation that ensures equitable data access.

Moving forward, autonomous features will expand, over-the-air updates will become standard, and data volume will increase. The question isn’t whether connected vehicles will reshape the repair industry; it’s whether independents will have a seat at the digital table – or if they’ll get locked outside the server room.

The mission to restore safety and mobility hasn’t changed, but safely repairing connected cars requires more than what meets the eye. These cars are no longer merely metal and mechanics; they are a digital nervous system on wheels, and safe, proper repairs demand software precision, data literacy and vigilance.

Whether shops like it or not, they’re not working on both the car’s body AND its brain.
