ADAS calibration documentation is among the most frequently incomplete service records, particularly when the underlying work (glass, body, alignment) is performed by a non-dealer provider. The documentation gap tends to surface only when a later warranty claim references the prior calibration.
'Calibration completed' as a single line on a repair order, without an accompanying scan report or certificate, has been flagged in warranty disputes as insufficient evidence that calibration occurred to manufacturer specification.
Aftermarket windshield use is sometimes recorded on the parts invoice but not propagated to the calibration record, producing inconsistencies between the two documents that can be cited later.
Sublet calibration — where a body shop or glass shop sends the vehicle to a dealer or third-party calibration provider — frequently breaks the documentation chain, with each party assuming the other is providing the certificate to the owner.
Multiple calibration attempts that ultimately succeed are sometimes documented as a single successful event, omitting the failed attempts. Whether this matters depends on the underlying cause of the initial failures.
