What front radar calibration does
Bumper work or a minor hit can shift your front radar. Adaptive cruise control and automatic braking use it to watch the car ahead.
Calibration re-aims the front radar sensor so it looks straight down the road. Adaptive cruise control calibration is this same job.
The wheels are checked first, since the radar is aimed the way the car drives. Calibration can't fix a bent bracket or damaged radar.
Static calibration aims it at a target in a level bay. Dynamic is a drive while the radar learns its angle.
Either way, it's one price per radar.
Three ways a front radar ends up needing calibration
-
The bumper, grille or emblem came off
Body work, or a headlight job with the bumper off, can move the radar. If your car's procedure calls for it, we re-aim it.
-
A new radar went in
A new radar may need setting up for your car before it is aimed. Tell us who installed it and if it is new.
-
Cruise control acts up, dash is clear
Braking for nothing, or losing the car ahead on a straight road. Tell us when it happens and what work was done.
Front radar calibration prices
Re-aiming your front radar is one price, whichever method your car needs. A new radar also needs setting up, priced on its own row.
Prices are before sales tax. Whether labor is taxed depends on your state; any tax that applies is itemized on your written quote.
What happens after you send the form
- 1
Send the VIN and what was done
Say what was repaired or replaced at the front, and any dash message. The VIN shows which radar your car has.
- 2
Get your written quote
A written price comes from the service center or mobile technician that covers your ZIP code. You agree before a date is set.
- 3
Checks before aiming
The technician checks the radar's mounting and your wheel alignment. Anything bent or out of spec is named before aiming.
- 4
Aiming and checking
The technician aims it with a target, a drive or both, as your car's procedure says. The result is checked against the automaker's limit.
What to have ready
- Your VIN, and the exact dash message, or say the dash is clear.
- The work done: what was repaired, removed or replaced at the front.
- A replaced radar: new or used, and who installed it.
- Paperwork: the repair order, an alignment printout or a scan report.
Lifted, or on bigger tires? Say so. Missing a detail? Send what you have.
Know your front radar calibration
After front-end work, your radar may need aiming. Your car's maker decides when, and how.
The radar aims where your car drives. One degree off misses by five feet at 300 feet.
So two things are checked before aiming:
- The steering sensor reads straight ahead when the wheels are straight.
- The rear wheels push the car straight, not slightly sideways (the thrust angle).
An alignment out of spec is fixed first. Send the printout if you have one.

Static: a target stands at a set height and distance. The floor is level, the bay lit.
Dynamic: a drive while the radar learns its angle. Hills, sharp curves, tunnels and empty roads slow it.
Both: some cars, Ford's among them, need a hand adjustment and then the drive.
Your VIN tells us which your car takes. You don't need to know.

Each automaker draws the line in its own place:
- Toyota: a radar, grille or bumper cover removed or replaced, or a wheel alignment.
- Honda: the radar removed or replaced, or bumper repair within a foot of it. Alignment alone, usually not.
- Ford: the radar, its bracket or the bumper beam moved. Not a bumper cover alone.
- Nissan: any driver assist part removed or replaced, and even an alignment.
A clear dash doesn't settle it; an off-aim radar may stay silent. Your quote says if yours needs it.

Most front radars sit low in the bumper or behind the grille emblem. See where yours sits.
These stop a good aim:
- A bent bracket, sometimes too slight to see.
- Paint: three or more coats over the radar can weaken or deflect its signal.
- The wrong grille or emblem, or a painted or wrapped radar cover.
- A lift kit or bigger tires, which change the radar's height.
Each one is found and named first. Aiming again fixes none of them.

A new radar may need coding, setup for your car, before aiming. Coding costs $275, aiming $330.
Service manuals call it a millimeter wave radar, a driver assist (ADAS) sensor.
Order a new one by VIN. Nissan's January 2026 statement calls salvaged or aftermarket radars "strictly prohibited".

Front radar calibration questions
$330 per front radar sensor at a service center, static, dynamic or both. A new radar that needs coding adds $275.
Prices are before sales tax. A diagnostic scan, when your job needs one, is priced and itemized separately.
Body work, the radar part and any alignment aren't included. See the full price list.
It can. A radar knocked slightly off aim often keeps working with no light on. You notice it as cruise control braking for nothing.
If the radar or bumper around it moved, it needs checking against your car's procedure. Blocked message, no work? See front radar blocked.
The car drives normally. But cruise control that keeps your distance and automatic braking may misjudge the car ahead.
Don't rely on them until the radar is re-aimed. Book it soon after the work.
Often, yes. Dynamic calibration runs on the road, so it can be done as a mobile visit.
Static calibration needs a level, lit, measured space, so whether your job can be done mobile depends on what your car's documented procedure calls for.
On a mobile visit, the radar costs $330. That's the same as at a service center.
Then something else needs fixing first. It might be a bent bracket, a cover the radar can't see through, or a faulty radar.
The technician tells you what was found and what has to change. Nothing extra is done without a new written quote.
Check your policy. After a collision claim, ask the adjuster whether the calibration belongs to the repair, since the repair caused it.
Your written quote lists the calibration, and the scan if your job needs one. Share it with the adjuster.
