What to Do If Airbags Didn’t Deploy: Car Accident Lawyer Investigation Tips

Airbags are supposed to be the last line of defense when metal meets physics. When they don’t deploy during a serious crash, something feels deeply wrong. Clients come to me rattled, bruised, sometimes grieving, asking the same question: why didn’t the airbags go off? The answer lives at the intersection of design thresholds, sensor logic, crash dynamics, maintenance history, and sometimes corporate shortcuts. If you’re trying to make sense of a no-airbag crash — in Atlanta or anywhere — the path forward is part safety investigation, part legal strategy.

This guide walks you through how seasoned accident lawyers approach these cases, the steps to preserve critical evidence, and how to weigh your options when you’re staring at a wreck that feels like it betrayed you.

Why airbags fail to deploy: what’s normal and what’s not

Airbags are not designed to deploy in every collision. They are calibrated to “fire” in moderate to severe impacts that meet certain acceleration and direction thresholds. That means a low-speed bumper tap or a sideways scrape may not trigger them, and that can be perfectly appropriate. The difficult cases live in the gray zone — a heavy front-end crash with clear structural deformation, a head-on impact at city speeds, or a T-bone collision with cabin intrusion where you’d expect bags to pop.

Modern vehicles rely on multiple sensors and an algorithm in the Restraint Control Module (RCM), also called the Airbag Control Module (ACM). That module reads deceleration patterns in milliseconds. If the pattern matches a deployment map, it commands squibs in the airbags and pretensioners in the seat belts to fire. If the pattern doesn’t cross the threshold, or if the signal is interrupted, the system may stay quiet.

Common reasons for non-deployment in serious crashes include a deployment threshold set too high by the manufacturer, sensor misplacement or failure, damaged or disconnected wiring during the crash pulse, module fault codes from prior events, after-market modifications affecting the electrical system, and chronic non-use or misrouting of seat belts (some systems weigh belt status in their decisions). None of these should be guessed at. They should be tested, verified, and documented, which is where a careful legal investigation earns its keep.

The first hours after the crash: decisions that protect your case

I’ve watched strong claims dim because crucial evidence vanished within days. You don’t need to become a technician overnight, but a few deliberate actions can make a measurable difference.

    Photograph the inside of the vehicle thoroughly, including the steering wheel hub, dashboard, A-pillars, seats, and any visible modules or wiring. Panoramic and close-up shots help later when engineers model the crash. Ask the tow yard not to crush, part out, or dispose of the vehicle. Get the storage location, contact name, and a written hold if possible. Record your injuries and symptoms as they evolve. Airbag burns and bruising aren’t the only “proof” of a serious crash. The absence of those marks does not mean the crash was minor. Avoid altering the vehicle or removing aftermarket electronics. Even a “simple” stereo or dashcam install can matter to a factory electrical system. Call a car accident lawyer early, ideally before insurance adjusters send inspectors or move the vehicle. On serious cases, an Atlanta car accident lawyer can issue preservation letters within a day and line up an independent inspection before data is overwritten or power cycles clear volatile codes.

Those five bullet points are not about theatrics; they are about preserving what can be measured. Once a vehicle is repaired, scrapped, or the battery is disconnected and reconnected repeatedly, some digital traces get harder to authenticate.

What we look for in a no-airbag case

When I’m brought in as an accident lawyer to evaluate a no-deployment crash, I’m balancing three questions: is there a product issue, did crash dynamics explain the non-deployment, and how do we link the outcome to your injuries?

The forensic backbone usually involves:

A targeted vehicle inspection. We authorize a non-destructive inspection first: high-resolution photos of the frontal structure, crush patterns, sensor locations, and the steering column. We note any airbag system fault lights, missing fuses, altered wiring, or aftermarket devices spliced into power or CAN lines. On older vehicles, even a sloppy alarm install can introduce voltage noise that confuses modules during a crash pulse.

Electronic data retrieval. Most late-model cars store deployment decisions in the ACM. A certified technician uses a crash data retrieval (CDR) tool to download pre-crash data, seat belt status, vehicle speed estimates, delta-V (change in velocity), and deployment commands or inhibit flags. On many models, we can see five seconds of pre-crash speed, brake status, and throttle position. It’s not a crystal ball, but it helps anchor the physics.

Damage energy analysis. Photos and measurements tell a story. A severe crush without bag deployment could mean a sensor didn’t “feel” the event due to off-axis impact, or that the thresholds were too conservative. Conversely, a surprisingly light crush paired with major injuries can suggest a freak angle or a secondary event — for instance, a combination of curb strike followed by a pole impact.

Maintenance and recall review. We run the VIN through recall databases and technical service bulletins. Some manufacturers have acknowledged issues with modules, clocksprings, or software logic. A dealership service history can show prior fault codes or related warranty work. If a recall existed and wasn’t performed, responsibility can shift in interesting ways: manufacturer, dealer, or even a prior owner who ignored notices.

Biomechanical linkage. Medical experts compare injury patterns to the restraint system performance. Seat belt only, seat belt plus knee-to-dash, or unrestrained occupant dynamics can be modeled. In severe frontal impacts, lack of an airbag often increases head and chest injury metrics, particularly at city speeds between 25 and 45 mph. We want to connect that increased risk to your specific harm, not a theoretical curve.

When it’s a product case versus a crash-dynamics case

Manufacturers argue thresholds and software logic the way chefs defend recipes: with conviction and a binder of charts. Some no-deployment outcomes are defensible. For example, a shallow-angle glancing blow that peels back a fender can look dramatic but impart relatively low deceleration to the cabin. Other outcomes are harder to justify, like a straight-on collision with a solid object at 30 mph that cripples the bumper reinforcement and rails.

We sort cases into rough baskets:

Likely product defect. Serious frontal impact above typical deployment thresholds, proper seat belt use, no significant aftermarket tampering, clean power supply history, and a module download showing either inhibit flags or a suspicious lack of recorded data. If we can tie this to a known issue — a recall, a design change mid-generation, or a documented series of complaints — the case strengthens.

Crash dynamics explain non-deployment. Off-axis strike, underride/override configurations involving a high-sitting truck, or a secondary event where the most severe deceleration occurred after the initial impact in a direction not covered by that airbag’s deployment map. In some SUVs and trucks, certain low-speed barrier collisions don’t cross thresholds that bags require, even if the sheet metal crumples.

Mixed causation. The bag might have deployed late, or a single-stage deployment fired too gently for occupant size and position. These cases require deeper engineering analysis and sometimes component teardown to test squibs, inflators, and squib continuity.

The takeaway is not that you should accept the manufacturer’s first explanation. It’s that classification frames your next step — expert investment, negotiation posture, or both.

The clock is not your ally

Two time pressures loom: statutes of limitation and data volatility. In Georgia, the general statute of limitations for personal injury claims is two years from the date of the accident, with different rules for minors and government entities. Product claims can involve additional timelines and tolling issues. Practical deadlines are shorter. Tow yards want storage fees, insurers want vehicles moved, and salvage yards want metal processed. If you’re in or around Fulton, DeKalb, Cobb, or Gwinnett County, an Atlanta accident lawyer can usually get a preservation letter and storage coordination out within 24 to 48 hours, which buys room for a proper inspection.

Data volatility is even trickier. If the vehicle is powered repeatedly, some modules log “ignition cycles” that can change available data slices. If the battery is disconnected and reconnected, volatile memory can clear. That doesn’t make your case impossible, but it raises the cost and complexity of proof.

How an experienced injury lawyer builds leverage

A good injury lawyer is part investigator, part storyteller, and part strategist. The goal is to turn technical facts into a narrative that makes responsibility clear and compensation plausible.

We start by locking down physical and digital evidence, then mapping the crash in human terms. If the driver braked hard while trying to avoid a turning vehicle, we explain how that deceleration should have cued the algorithm, how similar models deploy under matching conditions, and how a failure increased head injury risk. We put doctors and engineers in the same room, literally or figuratively, so the medical picture syncs with the physics.

We talk costs in real numbers. Hospital bills, imaging, follow-up care, physical therapy, time off work, help with daily tasks you can’t perform, and the grim math of future treatment. If an airbag failure turned a survivable collision into a life-altering injury, that differential becomes the heartbeat of the claim.

We also acknowledge alternative causes early, not at the last minute. If there’s a credible argument that an underride with a semi’s trailer shifted vectors outside a frontal bag’s map, we fold that into a claim against the trucking company whose equipment lacked proper underride guards. A skilled truck accident lawyer looks beyond one georgia car accident lawyer defendant. Multi-defendant claims are complex, but they often mirror real-world causation more accurately.

Special considerations with different crash types

No two crashes are the same, but patterns emerge over years of case work.

Frontal impacts at city speeds. Pedestrian islands, traffic lights, turning lanes — lots of Atlanta collisions happen between 25 and 45 mph. These are classic airbag territory when the strike is direct and the bumper reinforcement takes the hit. If the bag didn’t deploy, look hard at thresholds, sensor location, and wiring integrity.

Side impacts and oblique angles. Side curtain and seat-mounted airbags are governed by different algorithms. A T-bone can cause serious injury even when frontal bags stay quiet, which can be appropriate. The question is whether the curtain or side bag should have fired.

Underride with trucks. In an underride, a passenger car’s nose can submarine under a higher chassis, especially on older trailers missing compliant guards. The frontal crash pulse can be strange — severe structural crush without a conventional deceleration signature at the module’s location. Here, a claim against the trucking company and trailer owner may be stronger than a pure product claim. An Atlanta truck accident lawyer will analyze the guard design, maintenance, and lighting.

Motorcycle collisions. Motorcycles with factory airbags are rare, limited to specific models and configurations. Most riders rely on helmets and protective gear. If an automotive airbag fails in a car-versus-motorcycle crash, the analysis focuses on the passenger vehicle. A motorcycle accident lawyer examines visibility, right-of-way, and speed while also looking at the car’s restraint system performance.

Rollover events. Some vehicles fire curtains in rollovers using gyroscopic sensors. If a curtain doesn’t deploy and occupants strike the side glass or roof rails, module downloads and sensor orientation become crucial.

The role of manufacturer communications and prior incidents

Discovery can surface internal documents that change the tone of a case: evolution of deployment thresholds across model years, supplier emails about inflator variability, engineering debates about sensor placement, or field reports of non-deployment under real-world conditions. A pattern of complaints, even without a formal recall, can support notice and feasibility arguments. You don’t get those documents by asking nicely; you get them with focused requests, depositions, and the willingness to push past “confidential” stamps. That’s where an experienced Atlanta injury lawyer earns their keep.

What your own actions mean for the claim

The defense will scrutinize seat belt use, occupant position, and modifications. If you were belted, sitting upright, and the crash geometry points frontal, non-deployment looks worse for the manufacturer. If you were out of position — leaning forward to reach the console, for example — deployment could have caused injury, which complicates causation. Aftermarket changes to electrical systems, especially those tapping into ignition or accessory power, give the defense something to blame. We don’t sugarcoat these realities, we manage them with facts and qualified experts.

Medical proof and the airbag’s missing cushion

Airbags do two things in the first 50 milliseconds: slow the head and chest and spread force over a broader area. Without that cushion, occupants tend to hit the steering wheel, dash, or A-pillars. We often see facial fractures, dental trauma, sternal or rib fractures, and cervical injuries. Seat belts save lives but can’t prevent all forward motion. A properly functioning airbag reduces peak forces measurably.

Your medical records, imaging, and treating physician testimony are not just about pain and recovery; they are about physics. If the evidence shows a 30 to 40 percent reduction in head injury criterion when airbags deploy in comparable conditions, that data helps a jury understand why the missing bag matters.

Realistic settlement dynamics

Not every no-airbag case goes to trial. Many resolve when the technical report lands on the other side’s desk. The size of a settlement depends on injury severity, clear causation, and the strength of the defect proof. A modest soft-tissue case with disputed deployment expectations may settle in the tens of thousands. A traumatic brain injury tied convincingly to a non-deployment can reach seven figures, sometimes more when punitive exposure exists due to ignored warnings or delayed recalls. Numbers vary by venue, facts, and insurance layers. In the Atlanta metro courts, juries take seriously the idea that safety systems should work when people need them most.

Insurance angles you shouldn’t overlook

Two insurance streams can apply in parallel: the crash liability claim and a product liability claim. If another driver caused the collision, their liability coverage is still primary for your injuries. The product claim against the vehicle manufacturer or component supplier addresses the increased harm from the airbag failure, and those defendants typically bring their own insurers and counsel. Your own uninsured/underinsured motorist coverage can also come into play, especially if the at-fault driver’s limits are low. The choreography here matters, because releases signed in one claim can affect the other. Coordinate these pieces through a single injury lawyer who can protect subrogation rights and settlement sequencing.

Spoliation: the quiet threat to your case

Evidence that disappears — intentionally or not — can cripple your claim. Georgia law recognizes spoliation, and courts can sanction parties who let crucial evidence vanish after being put on notice. That’s why preservation letters go out early to tow yards, insurers, dealerships, and manufacturers. We specify no battery disconnects, no module clearing, no teardown without notice. If you hand your car to a body shop before counsel is involved, you risk losing the most important components of your case to a well-meaning repair estimate.

Cost, experts, and how fees work

Airbag cases are expert-heavy. Expect fees for a crash reconstructionist, a biomechanical engineer, and a restraint systems expert who understands module logic and component testing. Add in a medical expert, sometimes a human factors specialist, and the cost climbs. Reputable firms front these expenses and work on contingency, meaning you don’t pay unless there is a recovery. Ask about how costs are handled if the case doesn’t resolve, and make sure you understand the firm’s plan for expert selection. A generalist won’t do. You want someone who can talk squib resistance and inflator chemistry in a way a jury can grasp.

How Atlanta-specific experience helps

Atlanta’s traffic patterns, road designs, and court practices shape these cases. Intersections along Peachtree, Northside, and Buford Highway generate particular crash angles and speeds. Local hospitals and trauma centers produce consistent medical documentation that can help anchor causation. Juries here respond to clear technical explanations and credible, practical testimony. An Atlanta car accident lawyer who has litigated against manufacturers and big insurers understands the tempo in Fulton and DeKalb courts, the judges’ expectations, and the defense firms’ playbooks. If your crash involved a commercial truck, an Atlanta truck accident lawyer will know where to find maintenance records, telematics, and driver logs that can add leverage. Motorcycle cases benefit from a lawyer who can counter bias against riders; an Atlanta motorcycle accident lawyer can present speed and visibility evidence that keeps the focus on the negligent driver and the car’s failed restraints.

A grounded path forward

Don’t let a silent airbag silence your claim. Start by preserving the vehicle and its data. Document your injuries and treatment without delay. Involve an injury lawyer who understands both crash reconstruction and product liability. Ask the hard questions about thresholds, module decisions, and prior incidents. Demand a narrative that ties engineering truth to human consequence.

If you’re in the Atlanta area, a consultation with an Atlanta injury lawyer can set the investigation in motion before crucial evidence slips away. If the crash involved a commercial vehicle, fold in a truck accident lawyer to widen the lens. If a motorcycle was part of the collision, bring in a motorcycle accident lawyer who can manage both the roadway analysis and the vehicle systems piece. The point isn’t to create a cast of thousands; it’s to assemble the few professionals who can prove, with clarity and rigor, that a safety system failed and that failure mattered.

A short checklist you can act on today

    Place a written hold on the vehicle at the tow yard or storage facility; request no repairs, teardown, or power cycles. Photograph the vehicle interior and exterior, your injuries, and the crash scene if safe to do so. Get medical evaluation within 24 hours, even if symptoms feel “manageable” at first. Call a car accident lawyer with product liability experience to issue preservation letters and schedule a CDR download. Avoid statements to opposing insurers about why the airbags didn’t deploy until you have counsel.

Airbags are supposed to work in the moments you can’t bargain with. When they don’t, you deserve a clear explanation and a fair outcome. With the right investigation and a deliberate legal strategy, you can move from bewilderment to answers — and from answers to accountability.
