Bottom line up front: if your vehicle has driver-assist features and you've had body work — even something that sounds minor, like a bumper cover replaced — there's a real chance one or more of those systems needs to be recalibrated. Here's what triggers it, why it gets missed, and how to make sure it actually got done.
Where your safety sensors actually live
The sensors behind your driver-assist features sit in exactly the places a collision tends to hit:
- Front radar — behind the grille or bumper (adaptive cruise, automatic emergency braking)
- Front camera — behind the windshield (lane-keep, lane departure)
- Blind-spot radar — in the rear bumper corners
- Surround-view cameras — in the mirrors, grille, and tailgate
- Parking sensors — in the bumpers
Why a repair throws them off
These systems work off precise aim. When a bumper cover comes off and goes back on, a radar behind it can shift by enough to matter. Replace a mirror, and the camera behind it needs re-aiming. Change ride height, alignment, or suspension parts, and the forward radar's reference to the road moves. Even a low-speed hit can knock a sensor bracket out of true. Once that aim is disturbed, the system can misjudge distances and react wrong — and it won't necessarily light up a warning to tell you.
Which repairs commonly require it
Bumper removal or replacement on radar-equipped vehicles, windshield replacement, mirror replacement, suspension/alignment/ride-height work, grille or emblem work in front of a radar, and any direct sensor replacement. When in doubt, it's a question worth asking before you take the car back.
Static, dynamic, or both?
Same as with glass work: static calibration uses targets in the shop on a level floor, dynamic uses a road drive so the system re-learns, and some vehicles need both. It's a measured procedure with a pass or fail — not a reset. (More on that in our windshield calibration post.)
Why it gets missed
Here's the gap: not every body shop is equipped to calibrate. Some sublet it, some don't do it at all, and whether it lands on the estimate can vary. That can leave you with a car that looks perfectly repaired but has a safety system that's slightly off. If your repair paperwork doesn't list the ADAS calibration, ask — and if the answer is fuzzy, get it verified. Many insurers do cover a required calibration as part of a proper repair, so it's fair to raise with your shop or adjuster.
How to get it checked or done at Spot-On
By appointment, in-shop. Call (210) 439-7905 with your year/make/model and what was repaired, and we'll confirm what your vehicle needs. We can also work with your body shop directly.
We're at 4715 N Stahl Park, Suite 105, San Antonio, TX 78217.
Look for "ADAS calibration" line-itemed on the estimate or final invoice. If it isn't there and your vehicle has driver-assist features, ask the shop directly — or call us to verify.
If you're a body shop
You don't have to own every target and fixture to hand back a properly calibrated car. Sublet the calibration to us and deliver the repair complete.
