Burn injuries from a car accident carry a combination of physical pain, medical complexity, and visible, permanent disfigurement that few other injury types involve at the same time. A second-degree burn across a forearm heals differently, and is valued differently in a legal claim, than the same burn across half of someone’s face. Because burn injuries can come from more than one legal source in a car crash, the vehicle’s own fuel system or battery pack failing, not just the other driver’s negligence, these claims often involve more moving parts than a typical Chicago accident case.
This guide covers how car accident burns are classified, what scarring and disfigurement damages actually look like under Illinois law, and how liability can run to a vehicle manufacturer as well as, or instead of, the driver who caused the crash.
How Burns Happen in a Car Accident
Vehicle fires are less common than other crash injuries but tend to produce some of the most severe outcomes when they occur. The mechanisms include:
- Fuel system rupture: A high-speed rear-end or side-impact collision can rupture a fuel tank or fuel line, especially in older vehicles or ones with design flaws that have triggered past recalls.
- Battery and electrical fires in EVs and hybrids: Lithium-ion battery packs damaged in a collision can ignite, sometimes with a delay of minutes to hours after the crash, and these fires burn hotter and are harder to extinguish than a conventional gasoline fire.
- Airbag deployment injuries: Airbags deploy through a small chemical explosion, and defective or improperly designed airbags have caused chemical and thermal burns to the face, hands, and chest even in survivable crashes.
- Contact burns: Exhaust systems, hot engine components, or a deployed airbag’s hot gases can cause contact burns even without a full vehicle fire.
- Chemical burns: Battery acid, coolant, or other fluids released in a collision can cause chemical burns on contact with skin.
Burn Degree Classifications and Why They Matter to a Claim
First-degree burns
Affect only the outer layer of skin (epidermis). Painful but typically heal within about a week without scarring. These generate real but limited claims.
Second-degree burns
Extend into the dermis, causing blistering, significant pain, and a real risk of scarring, especially without prompt, proper wound care. Deep second-degree burns often require skin grafting and can take months to fully heal.
Third-degree (full-thickness) burns
Destroy the full depth of the skin and often underlying tissue. These burns are frequently less painful at the burn site itself because nerve endings are destroyed, which sometimes misleads people about severity in the immediate aftermath. Third-degree burns virtually always require surgical intervention, including skin grafting, and produce permanent scarring.
Fourth-degree burns
Extend through the skin into muscle, tendon, or bone. These are the most severe classification and frequently require amputation or extensive reconstructive surgery, with permanent, life-altering functional and cosmetic consequences.
The degree of the burn drives the medical treatment pathway, and the medical treatment pathway drives the claim’s value. A second-degree burn treated with outpatient wound care is a very different claim than a third-degree burn requiring multiple grafting surgeries at a specialized burn center.
Total body surface area (TBSA) burned is another factor physicians use to gauge severity and predict complications, since burns covering a large percentage of the body carry significant risk of infection, fluid loss, and systemic complications well beyond the burn site itself. A burn covering 20% or more of TBSA is generally treated as a critical injury requiring specialized burn-center care, and the size of the burned area, not just its depth, factors directly into how a claim should be valued.
Scarring and Disfigurement as a Distinct Category of Damages
Illinois law recognizes disfigurement as its own compensable category, separate from pain and suffering and separate from medical expenses. This matters because a burn scar, particularly on visible areas like the face, hands, or neck, causes harm that persists long after the physical pain of the burn itself has resolved: social anxiety, employment discrimination in public-facing roles, difficulty in relationships, and a permanent, daily reminder of the crash every time the person looks in a mirror.
Proving disfigurement damages effectively typically involves:
- Photographic documentation at multiple stages of healing, not just the worst moment immediately after the injury.
- A plastic surgeon’s assessment of the permanence of scarring and the realistic outcome of any reconstructive procedures, including how many additional surgeries may be needed over a lifetime.
- Testimony about functional limitations where scarring restricts movement, such as scar contractures across a joint that limit range of motion.
- Testimony about the psychological and social impact, often supported by a mental health professional treating anxiety, depression, or body-image issues that developed after the injury.
Liability: Driver Negligence vs. Product Defect
A burn injury claim frequently involves two separate legal theories that can run alongside each other:
Ordinary negligence against the at-fault driver
If another driver caused the underlying collision that led to the fire, standard Illinois negligence law applies regardless of what ultimately ignited the fire, the driver who caused the crash is responsible for the injuries that resulted, including burns, as a foreseeable consequence of causing a serious collision.
Strict product liability against a vehicle manufacturer
Separately, if the vehicle itself had a defect that caused or worsened the fire, a fuel tank positioned in a way that made rupture more likely in a foreseeable rear-end collision, a battery management system that failed to prevent thermal runaway, or a defective wiring harness, the manufacturer can be held strictly liable under Illinois product liability law. This claim doesn’t require proving the manufacturer was careless, only that the product was unreasonably dangerous as designed or manufactured, and that the defect caused or worsened the injury. These claims are subject to Illinois’s product liability statute of repose under 735 ILCS 5/13-213, which generally bars a strict liability claim more than 12 years after the product was first sold or 10 years after it was first delivered to its initial user, whichever comes first, with exceptions where the product was later modified or where the discovery rule applies.
Preserving the vehicle itself, not repairing or scrapping it before an engineer can inspect the fuel system, battery pack, or wiring, is critical evidence in any case where a product defect is a possibility. Once a damaged vehicle goes to salvage, that evidence is frequently gone for good.
The Real Treatment Path for a Serious Burn
Burn treatment doesn’t end when the wound closes. A patient with a significant second- or third-degree burn typically goes through an acute phase at a specialized burn unit, sometimes a lengthy ICU stay if the burn covers a large body surface area or involves inhalation injury from smoke, followed by debridement procedures to remove damaged tissue, and skin grafting where the burn is too deep to heal on its own. After the wound itself closes, the harder part often begins: months of physical and occupational therapy to prevent scar contractures from limiting joint movement, compression garment therapy worn nearly around the clock to flatten and soften developing scar tissue, and in many cases, laser treatments or additional revision surgeries over the following one to two years as the scar matures.
Pain management deserves particular attention in a burn claim. Dressing changes on a significant burn are, by consistent medical and patient accounts, among the most painful routine procedures in medicine, and they may need to happen daily for weeks. A claim that only accounts for the surgical bills and misses the extended course of therapy, compression garments, and the pain of the recovery process itself is significantly undervaluing what the person actually went through.
Insurance Coverage Layers in a Vehicle Fire Case
Because a vehicle fire claim can involve both a negligent driver and a potentially defective vehicle, the available insurance and liability sources are often broader than a typical crash: the at-fault driver’s auto liability policy, the vehicle manufacturer’s product liability insurance if a defect contributed to the fire, and in some cases a parts supplier’s insurance if a specific defective component, rather than the vehicle’s overall design, caused the failure. Umbrella and underinsured motorist coverage on the injured person’s own policy can also come into play when the driver’s liability limits are insufficient for the scale of a serious burn injury, which is common given that Illinois’s minimum liability requirements are far below what extensive burn treatment and reconstructive surgery actually cost.
Hypothetical Example: Two Claims From One Fire
The following is a hypothetical scenario illustrating how these claims can run together. It is not a description of any real client or case outcome.
Imagine a driver rear-ended at a stoplight on the South Side whose vehicle catches fire minutes after the initial impact, causing second- and third-degree burns to her arm and hand as she exits the vehicle. The rear-ending driver is liable under ordinary negligence for causing the crash that led to the fire. Separately, if an engineering inspection reveals the fuel line ruptured in a way inconsistent with the vehicle’s own safety design specifications, a product liability claim against the manufacturer may also be available, potentially reaching insurance coverage far beyond what the at-fault driver’s personal auto policy could ever provide for the scale of a serious burn injury.
Illinois Deadlines to Know
A standard negligence claim against an at-fault driver follows Illinois’s two-year statute of limitations under 735 ILCS 5/13-202. A strict product liability claim against a manufacturer follows a similar two-year discovery-based limitations period but is also bound by the outer statute-of-repose deadline described above. Because a burn injury case may involve both theories, and because vehicle preservation and expert inspection need to happen quickly before evidence is lost, getting legal advice soon after a vehicle fire, not months later, materially affects what claims remain available.

Frequently Asked Questions
Can I sue the car manufacturer if a defect caused my burn injury?
Potentially, yes. If a vehicle defect, such as a fuel system that ruptured in a foreseeable collision or a battery pack that failed to contain thermal runaway, caused or worsened your burn, Illinois strict product liability law allows a claim against the manufacturer separate from any claim against the at-fault driver.
What if my burn scars are on a part of my body that isn’t usually visible?
Disfigurement damages aren’t limited to visible scarring. Scars anywhere on the body that cause functional limitations, chronic pain, or psychological impact are compensable, though visible scarring on the face, hands, or neck often carries additional weight given its unavoidable daily social impact.
How many surgeries might a serious burn require?
It varies widely by severity and location, but third- and fourth-degree burns frequently require an initial grafting surgery followed by one or more revision surgeries over subsequent years as scar tissue matures and, in growing children, as the body changes. A burn injury claim should account for this realistic surgical timeline, not just the initial hospitalization.
Should the vehicle be preserved after a fire?
Yes, whenever a product defect is even a possibility. Once a burned vehicle is scrapped or repaired, the physical evidence an engineer would need to determine whether a defect caused or worsened the fire is typically lost permanently.
Is a burn injury claim worth more than a typical car accident injury claim?
Burn injuries often involve more extensive medical treatment, higher permanent impairment, and a distinct disfigurement damages category, all of which tend to increase claim value compared to injuries that heal without visible permanent effects. The actual value still depends on severity, documentation, and available insurance coverage.
What if I can’t identify what caused the fire myself?
That’s exactly what a fire origin-and-cause investigation and, where appropriate, an automotive engineering expert are for. Determining whether a fire started from crash-related fuel or battery system damage versus some other cause requires physical inspection of the vehicle and often review of the local fire department’s own incident report as a starting point. Waiting too long to preserve the vehicle can make that determination impossible.
