After a bumper repair my parking sensors started reacting late and the blind spot alert went quiet in spots where it used to warn me. How do you normally confirm that ADAS calibration was really performed and not just skipped

Sharing what I went through with my own car after a rear panel replacement. Visually the work looked clean, but the assistance systems behaved differently from before, and the shop that handled the body work never mentioned recalibration once. That pushed me to read up on how radar, lidar, and camera based systems have to be reset to factory spec any time a bumper, windshield, or panel near a sensor is touched. One page laid out the scope of that work clearly and you can view it here, mainly because it lists what recalibration actually covers instead of leaving it vague. My general takeaway is that this step is not an extra add on but part of finishing the repair properly, and I would rather deal with a place that explains its equipment and standards than one promising the fastest turnaround.
