If you bought a salvage or rebuilt title vehicle, the collision that caused the insurance write-off almost certainly displaced one or more ADAS sensors. The repair shop that rebuilt it may have made the car look perfect - but ADAS calibration requires specialist equipment most salvage rebuilders don't carry.
Every salvage title vehicle was in a collision severe enough for an insurer to declare it a total loss. The repair shop that rebuilt it replaced panels, fixed the structure and made it road-ready. But ADAS calibration requires OEM-grade diagnostic software, manufacturer-specific targets, a controlled workshop environment and trained technicians. Most salvage rebuild shops don't have this equipment. The sensors moved in the crash. The body was fixed. The sensors were never recalibrated.
Salvage title: The vehicle was declared a total loss and hasn't been inspected for roadworthiness. ADAS is almost certainly uncalibrated. Do not drive until checked.
Rebuilt title: The vehicle was rebuilt and passed a state inspection. However, most state inspections don't check ADAS calibration. They verify structural integrity, brakes, lights and emissions - not whether the forward radar is pointing at the right lane or the windshield camera is reading accurate distances. A rebuilt title does not mean ADAS is calibrated.
State inspection requirements vary widely. Some states don't even require a rebuilt vehicle inspection at all. Others check basics but nothing ADAS-related. Maryland SB 789 is the first state bill that would establish ADAS-specific calibration standards - but it's not yet law. Until the regulatory environment catches up, verifying ADAS calibration on salvage and rebuilt vehicles is the buyer's responsibility.
No calibration certificate. If the seller can't provide ADAS calibration documentation, the sensors weren't recalibrated. Ask specifically for the calibration paperwork. "The shop checked everything" is not the same as a calibration certificate from an ASE-certified ADAS provider.
Active ADAS warnings. Test drive and check the dashboard: "Pre-Collision System Malfunction," "Front Assist Not Available," "Forward Collision Alert Unavailable," "Co-Pilot360 Not Available." If any appear, the ADAS was not recalibrated. See our warning lights guide.
Systems that work but behave oddly. More dangerous than visible warnings. Adaptive cruise that tracks erratically. Lane keeping that pulls to one side. AEB that fires randomly (phantom braking). These indicate sensors operating but misaligned. Stellantis vehicles are especially prone to "soft faults" that don't trigger warning lights or DTCs.
Aftermarket windshield. Many salvage rebuilds use aftermarket glass to cut cost. On Honda/Acura models, aftermarket glass has a 30% calibration success rate. On Audi, aftermarket glass is formally rejected for ADAS vehicles. If aftermarket glass was installed, camera calibration may fail until OEM glass is fitted.
Carfax/AutoCheck gaps. Not all ADAS calibration work shows up in vehicle history reports. A clean Carfax doesn't mean the ADAS was properly recalibrated. Only a current diagnostic scan can confirm.
A full-system diagnostic scan covers every ADAS module - not just the visibly damaged area. We scan chassis, body and network control units to identify stored codes, pending codes, and modules in degraded states.
Collision damage cascades. A front impact that broke a sensor can cascade through the CAN bus to affect blind spot sensors at the rear. A windshield replaced during the rebuild may have left the camera uncalibrated. A battery disconnection during repair may have put modules into reset states. The full scan catches all of it.
After the scan, we calibrate every system that's out of spec. Camera, radar, blind spot, parking, surround-view - whatever the vehicle has and whatever the collision displaced. The result is documented with a calibration certificate.
Most salvage vehicles need a full system reset: $599 starting price, covering diagnostic scan, calibration of all affected systems, verification and certificate. If only one system is affected (rear-only impact, BSM only), it's less. Radar calibration from $399. Camera from $249. We confirm scope and price after the initial scan.

Answers to frequently asked questions on this topic
No state currently mandates ADAS calibration on salvage or rebuilt title vehicles. But the collision that totaled the car almost certainly displaced sensors. Driving with uncalibrated ADAS means safety features are non-functional or inaccurate. If uncalibrated ADAS contributes to an accident, it could affect your insurance and liability.
Ask for the ADAS calibration certificate from an ASE-certified or I-CAR certified provider. If no certificate exists, the ADAS was either not calibrated or checked with a basic code scan that doesn't verify sensor alignment. A diagnostic scan at our shop confirms the actual calibration state.
Generally no. Insurance covers ADAS calibration triggered by a new insured event. Calibration needed due to a historical repair is typically the owner's responsibility. The cost is a worthwhile safety investment for a salvage vehicle.
Almost certainly not. Most state inspections check structure, brakes, lights and emissions. ADAS calibration is not part of standard inspection criteria in any state yet. Maryland SB 789 is the first bill establishing ADAS-specific standards, but it hasn't passed. A passing state inspection does not mean ADAS is calibrated.
