Just five years ago, after a minor bumper impact, drivers typically replaced the plastic, mountings, and perhaps a headlight. Today, the same impact can damage the adaptive cruise control radar , the automatic braking camera, the parking sensors, and the ADAS control units. As a result, repairs become two to three times more expensive than they initially appear.
Modern cars are packed with safety electronics: radars behind the grille and bumper, cameras in the mirrors and windshield, and ultrasonic sensors around the body. Even if the part appears to be intact, the system may require calibration after repair—a procedure that adds between 10,000 and 33,000 UAH to the bill and increases repair time by 3–5 days.
In this article, we'll explore which ADAS components are most often damaged in minor accidents, how much they cost to replace and calibrate, and when a used, original part can be a reasonable alternative to a new one—without sacrificing quality or safety.
Why has repairing modern cars become more expensive?
According to CCC Intelligent Solutions, 35.6% of all auto body repairs already require ADAS system calibration—that's one in three cars in the shop. A year ago, only one in four cars required such calibration, and forecasts for 2027 indicate that this figure will approach 50%.
The reason is simple: automakers are introducing safety assist systems en masse, even in budget models. What was once an option for premium models is now standard on most new cars.
European Euro NCAP requirements effectively oblige manufacturers to install automatic braking, lane control and other systems to achieve high safety ratings.
As a result, what drivers perceive as a "light bump in the corner" now regularly results in large repair bills.
Which ADAS components are most often damaged in a crash?
Adaptive cruise control and automatic braking radars
Front radars are typically located behind the grille or inside the front bumper. Even if an impact doesn't visually damage these areas, a misalignment of a few millimeters renders the radar inoperative.
The cost of replacing a front radar sensor is 20,000–54,000 UAH for the part alone, plus 12,000–25,000 UAH for calibration. Rear radar sensors for the cross-traffic alert system cost about the same.
Cameras in the windshield
A camera for lane keeping, sign recognition, and pedestrian detection is mounted behind the rearview mirror inside the car. When replacing a windshield, the camera must be removed and reinstalled, and then calibrated—even if the windshield is being replaced not because of an accident, but simply because of a crack.
The camera costs between UAH 25,000 and UAH 33,000, the windshield and installation costs up to UAH 62,000, and camera calibration costs between UAH 10,000 and UAH 21,000. The total cost of replacing a cracked windshield on a car with ADAS can reach UAH 90,000.
Cameras and radars in mirrors
Side mirrors in modern cars are often equipped with all-round cameras and blind-spot monitoring radars. Replacing such a mirror costs between 30,000 and 66,000 UAH for the part alone.
At the same time, mirrors are one of the most vulnerable parts: they are broken in parking lots, hit in narrow passages, and hit by cyclists and pedestrians.
Ultrasonic parking sensors in bumpers
Parking sensors are built into the front and rear bumpers. A collision with a corner of the bumper often damages one or two sensors, and in some cases, the entire bumper, including its mountings and wiring, must be replaced.
The cost of replacing parking sensors ranges from 4,000 to 10,000 UAH for calibration, plus the cost of the sensors and bumper. If the bumper is severely damaged, the total cost of repairing the rear of the vehicle can reach 74,000 to 103,000 UAH, 40% of which is for ADAS components.
Control units and wiring
Modern bumpers, grilles, and fenders contain not only sensors but also control units, connectors, and wiring harnesses. Damage to wiring or connectors can cause system errors even if the sensors are intact.
ADAS control unit replacement: from 16,500 to 50,000 UAH depending on the vehicle model and system functionality.
What is ADAS calibration and why is it so expensive?
ADAS calibration is the process of precisely adjusting sensors and cameras to the manufacturer's specifications. Even if the component is not being replaced, but merely removed and reinstalled, calibration is mandatory.
There are two types of calibration:
Static calibration. The vehicle is installed in a special room in front of a screen with calibration targets; the procedure takes 1–2 hours.
Dynamic calibration. The vehicle must drive on a road with specific conditions (markings, speed, trajectory) to automatically adjust the system.
Failure to recalibrate after repairs may result in automatic braking not working, false system activations, or complete deactivation of the assist systems. In the event of an accident, the insurance company may deny payment if it is discovered that the safety systems were not recalibrated after the previous repair.
New, Replacement, or Used Original: What to Choose
Option | Pros | Cons | When it suits |
New original part | Maximum compatibility, factory calibration, manufacturer's warranty | Very high price (20,000–66,000 UAH for a radar or camera) | New car under warranty, sophisticated LiDAR systems |
New analogue | 30–50% cheaper than the original | May not be recognized by the control unit, no guarantee of compatibility | Simple ultrasonic parking sensors |
Factory quality, exact compatibility, price 2-3 times lower than a new part | Requires verification of the donor vehicle's performance and history | Radars, cameras, mirrors with sensors, bumpers with fasteners |
Used genuine ADAS radars and cameras are a reasonable alternative for vehicles older than 3-5 years, provided the part is removed from the vehicle without significant damage to the front end.
The main thing is to check compatibility using the OEM number, ensure there is no mechanical damage to the case and fasteners, and obtain a return guarantee in case of incompatibility.
What to Look for When Buying Used ADAS Components
Checklist before buying a used radar or camera
Does the OEM number match your model and year? Even within a single model, there may be different radar versions depending on the configuration.
Condition of the body and fasteners: cracks and deformations of the body make the part unusable.
Connectors and contacts: oxidation, traces of water, or melted contacts are signs of a problematic part.
Donor vehicle history: If the vehicle was in a serious frontal impact, the radars and cameras could have sustained hidden damage.
Completeness: the radar must come with fasteners and, if necessary, with a control unit.
Possibility of checking the functionality: Some auto dismantlers offer diagnostics of the part before sale or a return guarantee within 7-14 days.
Driver errors during ADAS repairs
Error | What is dangerous? | What is the correct way? |
Buy a radar or camera without checking the OEM number | The part may be physically suitable, but not recognized by the control unit due to incompatible software versions. | Always check the full OEM part number, not just the vehicle model name. |
Skip calibration after replacing a part | Automatic braking and lane control systems may not work or may trigger falsely. | Calibration is mandatory even when replacing with an identical part. |
Replace only the sensor without checking the wiring and connectors | The error may not be in the sensor, but in damaged wiring or an oxidized connector. | Diagnostics should include checking the entire circuit, and not just replacing a part by trial and error. |
Buy a used part from a car after a serious frontal impact | Radars and cameras may have suffered hidden damage that will only become apparent after installation. | Check with the seller about the nature of the damage to the donor vehicle |
Just reset the error without fixing the cause | ADAS systems are deactivated, the car loses safety functions | Resetting the error is not a repair; a full calibration is required. |
When a used original ADAS part is a good solution
A used part is suitable if:
This is an original radar, camera or mirror, removed from a vehicle without significant frontal or side damage.
The OEM part number matches your model and trim level.
There are photos of the part from all sides, including connectors and fasteners.
The seller provides information about the donor car (model, year, mileage, nature of damage)
The auto dismantling service provides a guarantee for the possibility of return or exchange within 7-14 days
A new original part costs 2-3 times more, and analogs do not guarantee compatibility.
The vehicle is older than 3-5 years and is not under factory warranty
It's best to be careful if:
The part was removed from the vehicle after a serious frontal impact or rollover.
The radar or camera housing has cracks, signs of repair or deformation
The connectors are oxidized, the contacts are melted or damaged
Missing mountings, control units or components
The seller cannot provide an OEM number or a photo of the back of the part.
There is no way to check the functionality of the part before installation
Your vehicle is under factory warranty, and installing a used part may void it.
FAQ
Is it possible to buy used ADAS radars and cameras?
Yes, if the part is genuine, the OEM number matches your model, and it was removed from a vehicle without significant damage to the front end. The main thing is to check the condition of the housing, fasteners, and connectors, and also check for returnability.
Is calibration required after replacing a radar or camera?
Yes, calibration is mandatory even when replacing an identical part. Without calibration, automatic braking, lane control, and adaptive cruise control systems may not function or may trigger incorrectly.
What is cheaper: a new analogue or a used original?
For ADAS components, used originals are often more cost-effective because similar products may not be recognized by the vehicle's control unit. A radar or camera from an unknown manufacturer costing 12,000 UAH may be useless if the system doesn't recognize it, while a used original costing 19,000 UAH is guaranteed to be compatible.
Can a damaged radar or camera be repaired?
In most cases, no. Radars and cameras are sealed units with precise factory settings. Attempts to open or repair them will result in complete loss of functionality.
Is it possible to install a used radar or camera yourself?
Physical installation is possible, but the system won't work without calibration using specialized equipment. Calibration requires a stand, calibration targets, and the manufacturer's software.
Conclusion on how to reduce the cost of ADAS repairs without sacrificing quality
Used genuine ADAS components offer a real opportunity to reduce repair costs by 2-3 times without sacrificing quality or compatibility. The key is to carefully check the OEM number, part condition, and the donor vehicle's history, and choose auto dismantlers that provide photos, descriptions, and a return guarantee .
When selecting a used radar, camera, or mirror with sensors, it's important not only to check the part number, but also to ensure there is no mechanical damage, check the condition of the connectors and fasteners, and clarify the return policy in advance in case of incompatibility.
