There is no doubt that vehicle safety technology is becoming more advanced every year. With equipment like lane-keeping assist, lane departure warning, blind spot monitoring, adaptive cruise control, and sign recognition coming standard in more and more vehicles, drivers are safer than ever before. With the advent of this technology, though, mechanics and repair facilities must follow manufacturer procedures more closely to ensure the equipment functions as intended. Even slight modifications or repairs on a vehicle can cause a loss of calibration in the Advanced Driver Assistance Systems (ADAS), which means they won’t work correctly, and this has become a massive issue.

In order for drivers to benefit from the ADAS technology on their vehicles, repair facilities need calibration information from the automakers, who have been reluctant to provide it. Some manufacturers have limited access to certain calibration data, which has historically directed many repairs back to dealerships.

A new bill, called the ADAS Functionality & Integrity Act, was introduced in Congress and, if enacted, would require manufacturers to provide certain calibration information to aftermarket businesses. Knowing how this bill will affect the functionality of your vehicle and your warranty will help you stay safe and keep your car running smoothly.

Why ADAS Is Becoming a Used Car Issue

For many years, ADAS safety features were limited to high-end luxury vehicles. In recent years, though, this tech has become common in all kinds of new vehicles, and many of those once new cars have made it to the used market. When you buy a vehicle that is equipped with ADAS equipment, you naturally assume that it is in good working order and has been properly calibrated. If the vehicle has been repaired or modified, though, the ADAS equipment might not be reading the road correctly, and you won’t be as safe as you should be behind the wheel. This is because there were no clear standards for how this equipment should be calibrated, which is why Congress has introduced this bill.

What the New ADAS Bill Changes

With the introduction of the ADAS Functionality & Integrity Act, Congress hopes to create clear, actionable standards for the calibration of ADAS features. It will require federal safety regulators to define how much a vehicle can be modified without breaking ADAS equipment, how to recalibrate equipment after repairs or modifications, and validation methods for ensuring proper functionality.

Since the bill’s introduction in December 2025, momentum has continued to build. In February, the ADAS Functionality & Integrity Act cleared an initial House subcommittee review and was advanced for further consideration, signaling growing bipartisan support. While the legislation has not yet been passed into law, this progress shows that federal regulators are actively working toward clearer standards for ADAS calibration and repair access.

For drivers, repair facilities, and warranty providers alike, this indicates that federal regulators are formally evaluating clearer standards, though the legislation has not yet been enacted.

In the past, aftermarket repair shops had to rely on incredibly vague guidance from OEMs to get safety equipment recalibrated. If this legislation passes, there will be concise guidelines and data provided to repair facilities. It will create benchmarks and consistency across the industry and help keep drivers safe, no matter what repairs they have gotten or what changes they have made to the vehicle.

How This Could Affect Used Car Value and Safety

When buyers purchase a car, even if it is used, they expect the safety systems to work properly. Without standard calibration information, though, this is next to impossible. Any kind of repair or modification, even something as simple as adding a bike rack, could potentially cause inaccuracies in the ADAS equipment readings. If this bill passes, though, buyers can rest easy knowing that their vehicles are going to be as safe as possible. Even if major modifications have been made, the aftermarket repair facility will have the information it needs to ensure that all safety equipment is working correctly.

As time goes on, ADAS calibration records are going to become more important. While things like maintenance documentation, accident reports, and title status already have a big impact on vehicle value, properly calibrated ADAS equipment will also determine how much a car is worth. Opening up this information to repair facilities beyond the dealership is beneficial for both service providers and drivers and will help sellers get more for their cars on the used market.

Where Extended Auto Protection Fits In

One of the issues that has come up with ADAS-equipped vehicles is that it can be very expensive to repair. The complex systems of cameras, sensors, and control units mean that any kind of problem can result in a repair bill costing thousands of dollars. This has been exacerbated by the fact that most systems could only be repaired at the dealership, which will almost always be more expensive than a third-party shop. If enacted, the bill could expand access to calibration information, which may improve repair accessibility.

Clearer calibration standards could help warranty providers more accurately assess ADAS system-related claims. In the past, unclear calibration guidance and post-repair modifications have made it harder to determine whether a failure was due to a defect or improper servicing. More defined standards may allow providers to better distinguish between the two, leading to more consistent claim evaluations.

What Used Car Buyers Should Know Moving Forward

Anyone who is considering purchasing a used vehicle moving forward needs to be thinking about ADAS equipment and taking its condition and calibration into consideration. Just like you would want to know what kind of condition a vehicle’s engine is in, you will want to have a good idea of how accurate the ADAS equipment is and when it was last checked and serviced.

One way to decide whether or not a vehicle’s ADAS equipment needs to be calibrated is to find out what repairs or modifications have been made. If, for example, the bumper was recently replaced, it is a good idea to find out what attention was paid to the ADAS equipment. Replacing exterior components can often affect the accuracy of the ADAS sensors and cameras, so requesting this documentation can ensure that a used vehicle is as safe as possible.
