Automakers promise that Advanced Driver Assistance Systems make the road safer. Lane keeping assist. When Driver Assistance Technology Fails, People Get Hurt

Automakers promise that Advanced Driver Assistance Systems make the road safer. Lane keeping assist. Automatic emergency braking. Blind spot monitoring. Adaptive cruise control. These systems are sold as safety features, and drivers are taught to trust them.

When they fail, the results are devastating. A braking system that does not engage. A lane assist feature that steers a car into oncoming traffic. A blind spot monitor that never sees the motorcycle. The people hurt in these crashes did nothing wrong. They trusted technology that a corporation designed, tested, and sold for profit.

At Collins Law Group, we represent people who suffered catastrophic injuries, and families who lost loved ones, in crashes caused by defective driver assistance technology. We hold the manufacturers, trucking companies, and repair facilities responsible for those failures fully accountable.

How ADAS Failures Cause Serious Crashes

These systems depend on cameras, radar, sensors, and software working together perfectly at highway speed. A single defect anywhere in that chain takes control away from the driver at the worst possible moment. Failures we investigate include:

  • Phantom braking. The vehicle slams on the brakes for no reason, causing a rear-end collision or a chain reaction crash.
  • Automatic emergency braking that never engages. The system was supposed to stop the vehicle. It did not.
  • Lane keeping malfunctions. False sensor readings steer the vehicle across the center line or into another lane.
  • Blind spot detection failures. The system fails to warn the driver before a lane change.
  • Pedestrian and cyclist detection failures. The vehicle does not see a person in the road until it is too late.
  • Software defects. A bad update disables safety features without warning, or the system behaves unpredictably after a patch.

A federal watchdog report found that many drivers do not understand what these systems can and cannot do, in part because automakers use different names for the same technologies and federal oversight has lagged behind the features themselves. When a manufacturer oversells what its system does, that is not just a marketing problem. It can be a failure to warn.

Who Is Responsible for an ADAS Failure?

Crashes involving driver assistance technology are not ordinary car accident cases. The question is not just who was driving. The question is who designed the system, who built it, who installed it, and who was supposed to maintain it. Depending on the facts, responsible parties may include:

  • The automaker or technology company that designed a defective system, failed to test it adequately, or failed to warn drivers about its limitations.
  • A trucking or commercial fleet company that ignored repeated system warnings, skipped required maintenance, or kept a truck with a known safety defect on the road. These cases often overlap with our truck accident practice, and recent developments in federal law have expanded who can be held accountable in commercial trucking crashes.
  • A dealership that sold a vehicle with a known defect or failed to perform recall repairs and required software updates.
  • A repair facility that botched a sensor recalibration after a windshield replacement or collision repair, leaving the system blind.

Under Illinois product liability law, every company in the chain of distribution can be held responsible when a defective product injures someone. Defects come in three forms: a dangerous design, a manufacturing error, or a failure to warn drivers about what the system cannot do. We pursue all of them.

The Evidence Disappears Fast. We Move Faster.

ADAS cases are won or lost on data. Modern vehicles record what the system saw, what it decided, and what the driver did in the seconds before impact. Event data recorders, telematics, camera footage, and software logs tell the real story of the crash.

That evidence does not preserve itself. Manufacturers and trucking companies have teams working to protect their interests from day one. We send preservation demands immediately, retain engineering and accident reconstruction experts, and force corporations to turn over the data they would rather bury.
