Car Insurance Claim Denied? Why Nearly Half Go Unpaid

Auto insurers closed 45% of resolved liability and medical claims without paying policyholders in 2025, up from roughly 35% a decade earlier — and the shift has little to do with a single bad-faith decision and everything to do with how claims files get built, disputed, and closed.

That figure comes from a Wall Street Journal analysis of thousands of insurer filings submitted to state regulators through the National Association of Insurance Commissioners. It does not mean 45% of drivers were wrongly denied: a claim can close without payment because another driver’s insurer paid instead, the loss fell below the deductible, the customer withdrew the file, or the damage sat outside the policy’s terms. What it does mean is that a policyholder filing a liability or injury claim today has meaningfully worse odds of collecting than one did in 2016, even as auto damage claims for collision and comprehensive repairs have closed without payment at a nearly flat rate — just under 25% — for a decade. This guide breaks down which carriers moved the most, why liability and medical claims are the ones absorbing the shift, and exactly what a driver can do before and after filing to protect a legitimate claim.

In practice, a driver who gets a no-payment letter from their insurer almost always assumes it means their claim was rejected outright. A very common scenario I run into when reviewing claim files is a driver who never filed anything wrong — the claim simply landed in a category, like an unlisted household driver or a comparative-negligence dispute, that carriers have started scrutinizing far more closely than they did five years ago. This guide walks through the mechanics behind the 45% figure, which companies and states show the widest swings, and the specific documentation habits that separate a claim that gets paid from one that doesn’t.

Why Are Car Insurance Claims Being Denied More Often in 2026?

Car insurance claims are being denied more often because insurers have tightened how they evaluate liability, injury, and medical claims specifically — not because they’ve become stricter across the board. The Wall Street Journal’s analysis, published August 9, 2026 and built on thousands of insurer filings to state regulators, found the no-payment rate on liability and medical claims climbed from about 35% in 2016 to 45% in 2025. Auto damage claims covering collision and comprehensive repairs barely moved over that same period.

BMO Capital Markets insurance analyst Michael Zaremski attributed part of the shift to insurers adding more procedural checkpoints, or “guardrails,” around liability and medical files, since those claims are more expensive on average and more likely to draw in an attorney before they close. The insurance industry has also pointed to rising fraud, including fabricated claims assisted by generative AI tools, as a contributing factor. Consumer advocates, including the Consumer Federation of America, argue tighter claims handling is at least partly a profit lever rather than a fraud-prevention measure — a tension this guide covers in more detail below.

During a claim analysis, the number that actually predicts trouble isn’t the headline percentage — it’s how much of a state’s or a carrier’s claims mix has shifted toward bodily-injury and liability files versus straightforward damage repairs. CCC Intelligent Solutions data cited in industry coverage shows bodily-injury claim frequency up 11% over two years, with claim cost up roughly 10.3% over the same window. When both frequency and severity rise on the exact category of claims that already draws the most scrutiny, a rising no-payment rate isn’t surprising; it’s close to mechanical.

Which Car Insurance Companies Deny the Most Claims?

Among the ten largest U.S. personal auto insurers, Liberty Mutual and Allstate closed the highest share of liability and medical claims without payment in 2025, both landing around 54%. Liberty Mutual saw the largest swing of any major carrier, climbing from 29% in 2016 to 54% in 2025 — a 25-point jump in a decade. Travelers sat at the opposite end, closing just 20% of liability and medical claims without payment in 2025, up only modestly from 13% in 2016.

A single-year snapshot can be misleading on its own, so before choosing or renewing with any carrier, it’s worth checking that company’s confirmed-complaint history through the NAIC’s Consumer Information Source, which lets you search complaint index data by company and by state for the past three years. A high no-payment rate paired with a low complaint index can mean a carrier is simply writing more complex liability business; a high no-payment rate paired with a high complaint index is a much stronger warning sign.

Why Do Liability and Medical Claims Get Denied More Than Damage Claims?

Liability and medical claims get denied more often than damage claims because they’re harder to value objectively, more likely to involve a dispute over who’s actually at fault, and far more likely to bring an attorney into the file before it closes. Auto damage claims, by contrast, usually come down to a repair estimate that either matches the vehicle’s actual condition or doesn’t — a narrower, more mechanical dispute.

A very common mistake I see drivers make is assuming that because their collision claim was paid quickly last year, their liability claim from a more recent accident should move just as fast. In many states, a liability claim triggers a fault investigation the moment another party reports an injury, and that investigation runs on a completely different timeline and evidentiary standard than a straightforward repair estimate. Higher accident severity nationally has compounded this: bodily-injury claim frequency has risen roughly 11% over two years, with claim cost up about 10.3% over the same period, according to claims-data provider CCC — meaning more of these harder-to-resolve claims are entering the system every year.

One meaningful counter-trend on the damage side: a growing number of states are giving policyholders a formal right to independent appraisal when they dispute the dollar amount of a physical-damage loss. Illinois Gov. JB Pritzker signed a right-to-appraisal law on August 7, 2026, taking effect July 1, 2027, joining Texas, where a similar law took effect September 1, 2025, and Washington, whose version applies to auto policies issued or renewed on or after January 1, 2026. These laws don’t touch liability or medical claim denials directly, but they give drivers a structured, binding way to challenge a lowball damage estimate without going to court — worth knowing about alongside Illinois’s separate efforts to curb rate hikes starting in 2027.

Are Insurers Making More Money While Paying Out Less?

Yes. Personal auto insurers paid about 61 cents in claims for every premium dollar collected in 2025 — the industry’s lowest net loss ratio since 2020, according to S&P Global Market Intelligence data cited in the Journal’s reporting — while posting a record $68.7 billion in underwriting income industry-wide. State Farm alone swung from a $2.7 billion auto underwriting loss in 2024 to a $4.6 billion gain in 2025. Allstate’s underwriting income hit $5.7 billion, more than triple its 2024 result.

State Farm, the nation’s largest auto insurer by market share, began issuing cash-back dividends to policyholders this month after roughly doubling its 2025 profit — even as its own no-payment rate on liability and medical claims climbed to 47% from 26% over the decade. That combination is exactly what’s driving the rate increases many drivers are already seeing on their renewal notices; if you’re trying to understand both sides of that squeeze, our coverage of rates climbing again in 32 states for 2026 lays out the premium side of the equation.

Consumer Federation of America insurance director Douglas Heller has argued that tightened claims practices help some insurers extract additional profit from policyholders who lack the resources to contest a denial. The Insurance Information Institute, for its part, counters that a claim can close without payment for entirely legitimate reasons and cautions that differing reporting practices across carriers can distort direct comparisons. Both points have merit: the underlying data shows a real, decade-long shift in outcomes, and reasonable people can disagree about how much of that shift reflects tighter fraud controls versus tighter profit management.

What Are the Most Common Reasons an Auto Insurance Claim Gets Denied?

The most common reasons a car insurance claim closes without payment fall into a short, fairly predictable list — and knowing which one applies to your situation determines whether an appeal is worth pursuing.

1. The loss fell below your deductible. If your $500 or $1,000 deductible exceeds the repair cost, the insurer correctly closes the claim without a payout.
2. The claim was withdrawn by the policyholder. Sometimes drivers file a claim, then decide to pay out of pocket to avoid a premium increase, and the file closes with no payment recorded.
3. Another driver’s insurer paid instead. In a clear liability case, the at-fault driver’s carrier — not yours — issues the payment, and your own claim shows as closed unpaid.
4. The loss fell outside the policy’s terms. Coverage exclusions, lapsed payments, or a loss type your policy doesn’t cover (like mechanical breakdown under a standard liability policy) all produce a no-payment outcome.
5. A comparative-negligence review reduced or eliminated the payout. If an adjuster determines you share fault, your recovery can shrink or disappear entirely depending on your state’s negligence rules.
6. An undisclosed regular driver was involved. As noted above, several carriers now treat an unlisted household driver as grounds to deny or limit a claim.
7. Suspected fraud. Insurers have flagged a rising volume of fabricated or exaggerated claims, including some assisted by generative AI, as a factor behind more claims being contested.
8. Complexity in a UM/UIM claim. When the at-fault driver carries no insurance or too little, your own uninsured/underinsured motorist coverage has to step in, and those claims are processed against your own carrier — sometimes with the same scrutiny as a third-party liability claim.

During a claim analysis, the fault-percentage dispute is the one that trips up the most policyholders, mainly because state law on the subject varies more than drivers expect. Some states follow a pure comparative-negligence rule, where you can recover damages even if you’re 90% at fault, just reduced proportionally. Others follow a modified rule that bars recovery once your share of fault crosses 50% or 51%, and a small number still follow contributory negligence, which can bar recovery entirely if you’re found even 1% at fault. Because these rules differ by state and directly determine whether a liability claim gets paid, it’s worth confirming your own state’s standard with your state insurance department or a licensed attorney rather than assuming your situation works the way a friend’s did in a different state.

Does the Car Insurance Claim Denial Rate Vary by State?

Yes, significantly. A separate Weiss Ratings review, cited by the advocacy group Citizen Action of New York, found large insurers operating in New York closed nearly half of liability claims in 2025 without payment, up from about a third in 2005 — and the largest carrier in the state closed 55.5% of claims without paying. That’s a steeper long-run climb than the national 35%-to-45% figure, suggesting some states are seeing the shift play out even faster than the countrywide average.

State-level variation isn’t limited to claims handling — it shows up in how many drivers on the road even carry the coverage that’s supposed to back up a liability claim. The Insurance Research Council found 15.4% of U.S. drivers, or about one in seven, were uninsured in 2023, with combined uninsured-and-underinsured driving reaching 33.4% of all drivers, roughly one in three, up about 10 percentage points since 2017. When the at-fault driver in your accident falls into either group, your own claim shifts from a straightforward liability filing against their insurer into a UM/UIM claim against your own policy — one of the more complex categories inside the same rising no-payment trend.

Regulatory response also differs sharply by state. New York enacted 2026 reforms requiring insurers to return “excess profits” to policyholders and restricting several rating factors — reforms our team covered in detail in New York’s new prior-approval rate law — even as the state’s own claims data shows one of the steepest liability no-payment climbs in the country. Not every state has moved on claims-handling transparency the way New York has moved on rate approval, so don’t assume your state offers the same consumer protections; check your own state department of insurance directly, since requirements genuinely differ from state to state.

How Can You Protect Your Claim Before You Ever File One?

The strongest protection against a claim closing unpaid happens before the accident, not after. Thin documentation, an unlisted household driver, or inadequate UM/UIM limits are the three most preventable reasons a legitimate claim gets denied or reduced.

• Document everything at the scene. Photos of all vehicles and the surrounding area, contact information for witnesses, and a copy of the police report close off the easiest grounds an insurer has to dispute a liability or medical claim.
• Review who’s listed as a driver on your policy today. If a household member regularly drives the insured vehicle and isn’t listed, notify your insurer before an accident happens — several carriers are now scrutinizing this detail closely at claim time.
• Consider raising your uninsured/underinsured motorist limits. With roughly a third of U.S. drivers uninsured or underinsured, this coverage is what stands between you and an out-of-pocket loss when the other driver can’t pay.
• Keep a written log of every adjuster interaction. Dates, names, and summaries of every call and email create the paper trail that strengthens any later appeal or state complaint.
• Shop around at renewal, not just on price. No-payment rates vary sharply by carrier, and comparing quotes can also surface companies with stronger claims-handling reputations.

How Do You Appeal a Denied Car Insurance Claim?

You appeal a denied car insurance claim by first getting the insurer’s reasoning in writing, then escalating internally, and finally taking the dispute to your state regulator or a licensed attorney if it remains unresolved.

1. Request the denial reason in writing. Ask for the specific policy language cited and the exact reason behind the no-payment decision. A vague verbal explanation from an adjuster isn’t sufficient grounds to accept a denial.
2. Escalate to a claims supervisor. If the initial explanation is thin or the file was closed quickly, ask explicitly to have it reviewed by a claims manager before you sign any release.
3. Use your state’s right-to-appraisal process for damage disputes. If the disagreement is over the dollar value of a physical-damage loss and you’re in Texas, Washington, or (starting July 2027) Illinois, invoke the formal appraisal process rather than negotiating informally.
4. File a complaint with your state’s department of insurance. Use the NAIC’s Consumer Information Source to locate your state DOI’s complaint process. Every state maintains one, and regulators track no-payment and complaint patterns by company over time.
5. Consult a licensed attorney for contested liability or injury claims. Comparative-negligence disputes and UM/UIM claims are the categories most likely to benefit from professional representation, particularly when the insurer’s fault assessment conflicts with the police report or witness statements.

Frequently Asked Questions About Denied and Unpaid Car Insurance Claims

What percentage of car insurance claims go unpaid?

Auto insurers closed 45% of resolved liability and medical claims without payment in 2025, up from roughly 35% a decade earlier, according to the Wall Street Journal’s analysis of NAIC filings. Auto damage claims for collision and comprehensive repairs closed without payment at a much lower, largely unchanged rate of just under 25%.

Why did my car insurance claim get denied?

Common reasons include a loss below your deductible, a withdrawn claim, payment issued by the other driver’s insurer instead, a loss outside your policy’s terms, an undisclosed household driver, or a comparative-negligence finding that reduced or eliminated your payout. Insurers also cite rising fraud, including AI-assisted fabricated claims, as a contributing factor.

Which car insurance companies have the highest claim denial rates?

Liberty Mutual and Allstate posted the highest 2025 no-payment rates among the ten largest personal auto insurers, both around 54%. Liberty Mutual saw the steepest climb of any major carrier, rising from 29% in 2016. Travelers had the lowest 2025 rate, at 20%.

Is a claim closed without payment the same as a denied claim?

Not exactly. “Closed without payment” is a broader regulatory category that includes claims paid by another driver’s insurer, claims withdrawn by the policyholder, losses below the deductible, and losses outside policy terms, in addition to outright denials. The rising rate still signals a real shift in outcomes over the decade, even though not every case represents a wrongful denial.

How do I appeal a denied car insurance claim?

Request the denial reason in writing, escalate to a claims supervisor if the explanation is thin, use your state’s right-to-appraisal process for damage-value disputes where available, file a complaint with your state department of insurance through the NAIC’s Consumer Information Source, and consult a licensed attorney for contested liability or injury claims.

Does an undisclosed driver on my policy affect my claim?

Yes. State Farm and other major carriers have tightened enforcement around undisclosed regular household drivers, and an accident involving an unlisted driver who regularly uses the insured vehicle can be cited as grounds to deny or limit a liability or medical claim.

Why does uninsured motorist coverage matter more now?

Because 33.4% of U.S. drivers were uninsured or underinsured in 2023, up roughly 10 percentage points since 2017, according to the Insurance Research Council. UM/UIM claims fall inside the same liability and medical category where no-payment rates have risen fastest, making adequate limits one of the most overlooked ways to protect yourself before an accident happens.

Is car insurance still required if claims are harder to get paid?

Yes. Liability auto insurance remains legally required in 49 states and the District of Columbia, with New Hampshire requiring equivalent proof of financial responsibility instead. A rising no-payment rate doesn’t change that legal requirement — it changes how carefully you need to document a loss and understand your policy before you rely on it.

What This Means for Your Next Renewal

The rising share of unpaid auto liability and medical claims is reshaping what drivers actually get for their premium dollar, even as insurers report record profitability and, in some cases, dividends back to policyholders. For millions of Americans required by law to carry coverage, the honest takeaway isn’t that insurance has stopped working — it’s that a policy is only as strong as the claim file behind it.

The drivers who come out ahead after an accident this year are the ones who treated documentation, driver disclosure, and UM/UIM coverage as routine maintenance rather than an afterthought. If you haven’t reviewed who’s listed on your policy or checked your uninsured motorist limits in the past year, that review is the single highest-leverage move available to you right now, regardless of which carrier’s name is on your declarations page.
