When Does a Car Need an ADAS Calibration?
The triggers that mean a vehicle needs recalibration.
Updated June 27, 2026 · 4 min read
Common triggers
A vehicle generally needs ADAS calibration after any work that disturbs a sensor or its mounting point. Even low-speed impacts and routine repairs can knock cameras and radar out of alignment.
- Windshield replacement (forward-facing camera)
- Collision repair, including bumper and panel work
- Alignment or suspension repair
- Sensor, camera, or radar replacement
- Ride-height changes
Why it isn't optional
ADAS features like automatic emergency braking and lane-keeping rely on precisely aimed sensors. A camera off by a fraction of a degree can misjudge distances — so skipping calibration can leave safety systems working incorrectly without any obvious warning light.
With the vast majority of new vehicles carrying at least one ADAS feature, calibration has shifted from a niche service to a routine, essential step on most repairs.
Frequently asked questions
- Does a windshield replacement always need calibration?
- If the vehicle has a forward-facing camera mounted to the glass, yes — almost always, per OEM procedures.
- Will the dashboard warn me if calibration is needed?
- Not always. A misaligned sensor can operate incorrectly without triggering a warning light, which is why following OEM triggers matters.
