Cameras And Radar Are Making Fender Benders Cost More, With AAA Finding Driver Assistance Systems Can Add Up To 37.6 Percent To Repair Bills, Including $1,540 After A Minor Front Hit

Remember when a minor fender bender meant a new bumper cover and a little paint? These days, the bumper may be hiding cameras and radar sensors, and replacing them can turn a small mishap into a surprisingly big bill.

A AAA study on advanced driver assistance systems, often shortened to ADAS, looked at what these safety features add to the cost of repairs. As reported by Repairer Driven News on December 19, 2023, the finding was that these systems can raise repair costs by up to 37.6 percent.

The study is a few years old, but the technology it describes has only become more common on new vehicles, so the lesson is still timely.

What the numbers look like

In the example of a minor front collision, the cost of the ADAS components came to $1,540. That was 13.2 percent of an $11,708 repair estimate. In other words, more than a thousand dollars of that bill went to the safety technology, even though the crash itself was minor.

Other figures from the study show how the costs add up:

Side mirror replacement: $1,067
Windshield replacement and calibration: $360
Individual ADAS component costs ranged from $290 to $1,596

A side mirror used to be a simple piece of glass in a plastic housing. Today it may have a camera, a turn signal and a sensor tucked inside, which is why one can cost more than a thousand dollars to replace.

Why the cost goes up

These systems are the reason many vehicles can warn you about a car in your blind spot, brake on their own or nudge you back into your lane. They rely on cameras behind the windshield, radar units behind the bumper or grille, and sensors in the mirrors and elsewhere around the body. Those parts are expensive, and they sit in exactly the places that get hit in a minor crash.

There is also the matter of calibration. After a repair, the cameras and sensors often have to be aimed and tested so that they see the road accurately. That takes special equipment and trained technicians, and it adds to the labor charge. The windshield figure in the study, which includes calibration, shows that even a glass replacement is no longer just a piece of glass.

What this means for your wallet

You do not need to avoid safety technology. These features are meant to help prevent crashes in the first place, and many drivers value them. But it pays to be realistic about the repair side of the equation. Here are some practical steps:

Call your insurance agent and ask how your policy handles repairs on a vehicle with these systems. Ask about your deductible and whether it fits your budget now that a small repair can cost more.
Check what your coverage includes for glass. Because windshields can involve calibration, a glass claim may be bigger than you expect.
When shopping, ask about repair costs, not just sticker price. A quick call to your insurer for a quote on a particular model can tell you a lot.
Park with care. Pull in slowly, back out slowly and leave a bit more room around your bumper and mirrors in tight spots.
Keep your tires properly inflated and your following distance generous. The cheapest repair is the one you never need.

When you do need a repair

If you do get into a collision, ask the repair shop directly whether the estimate includes the cost of checking and calibrating the driver assistance systems. Ask them to explain each line. A good shop will walk you through what is being replaced and why, and will make sure the safety features are working again before you drive away. If the estimate seems high, you are always free to get a second opinion.

It is also smart to keep your paperwork. Hold on to the estimate, the final invoice and any notes about calibration. If a warning light or a strange behavior shows up after the repair, you will have a record to take back to the shop.

The bottom line

Cameras and radar are doing a lot of good work on the road, but they have changed what a fender bender costs. The AAA study found that these systems can add up to 37.6 percent to repair bills, and that a minor front hit can carry $1,540 in ADAS component costs alone. Know your insurance coverage, ask smart questions before you buy and drive like a fender bender can be expensive, because these days it very well might be.

Questions worth asking your agent

When you next speak with your insurance agent, a few plain questions can save you a nasty surprise. Ask whether your policy pays for calibration after a repair. Ask whether there is a separate deductible for glass. Ask whether choosing a different deductible would change your premium by much. You may find that a slightly higher monthly payment buys real peace of mind, or you may decide your current setup is fine. Either way, you will be making the choice with open eyes instead of finding out after a crunch in the parking lot.
