Which car insurance company denies the most claims?

National auto insurance companies do not publish exact, ranked percentages for outright claim denials, but major carriers like Allstate, State Farm, and Liberty Mutual frequently receive the highest volume of consumer complaints regarding delayed, undervalued, or contested claims.

Understanding Auto Insurance Denials

• Lack of Central Data: State insurance commissioners track consumer complaints, but national denial rates for auto claims are rarely published as transparent leaderboards.
• The "Delay, Deny, Defend" Tactic: Legal analysts and former adjusters note that major firms like Allstate historically utilize strategies to minimize payouts through lowball offers rather than full rejections.
• Frequent Complaint Targets: According to legal reviews and consumer watchdogs, Progressive, Farmers Insurance, and State Farm frequently face bad-faith accusations or lawsuits for disputing severity and delaying settlements.
• Geographic Trends: Industry data indicates that states with high litigation rates like California, Texas, and Florida experience the highest overall volume of disputed and denied auto claims.

For Affordable Care Act (ACA) marketplace health insurance, Oscar Health recorded the highest average in-network claim denial rate nationally at 25%.

Denial rates differ by the type of insurance and market. Major insurers show distinct trends across different categories:

Health Insurance (ACA Marketplace)

• Oscar Health: Denied 25% of in-network claims.
• Molina Healthcare: Denied 22% of in-network claims.
• Guidewell (Florida Blue parent): Denied 22% of in-network claims.

Medicare Advantage Prior Authorization

• UnitedHealth Group: Denied 17% of prior authorization requests, the highest among major national payers.
• Centene: Denied 15% of prior authorization requests.
• Kaiser Permanente: Denied 13% of prior authorization requests.

Homeowners Insurance

• Allstate and USAA: Closed roughly 50% of property and homeowners claims without payment in recent industry reviews, significantly higher than the industry norm.
• State Farm Florida: Reported high property claim denial rates near 59% in high-risk regional markets.

Several major auto insurance companies frequently rank poorly in consumer satisfaction reports and legal analyses due to claim delays and low settlement offers. Legal advocacy groups and consumer watchdogs often highlight the following five large national carriers among the most difficult to deal with regarding claims handling:

• Allstate: Often cited by legal researchers for using aggressive "delay, deny, and defend" tactics and software like Colossus to minimize payout amounts.
• Liberty Mutual: Frequently criticized for high consumer complaint volumes, slow adjuster response times, and disputes over vehicle valuations.
• State Farm: Known in legal and consumer commentary for employing strict defense strategies that frequently result in delayed or contested payouts.
• Progressive: Often flagged by policyholders and consumer advocates for undervaluing vehicle damage claims and protracted dispute processes.
• Farmers Insurance: Routinely scores below average in consumer satisfaction surveys concerning collision repair experiences and claim settlements.

Allstate is frequently ranked by consumer advocacy groups and legal watchdogs as one of the worst insurance companies for paying claims fairly.

Top Poorly Rated Insurers for Claims

Consumer reports, legal studies by the American Association for Justice, and policyholder complaints often single out these companies for difficult claims processes:

• Allstate: Frequently tops the "worst" lists. It uses a software tool called Colossus to lower injury and damage payouts. It is known for a strict strategy to delay or deny valid payments.
• State Farm: Often criticized for dragging out investigations, fighting repair estimates, and refusing to admit fault quickly.
• Liberty Mutual: Ranked low in customer satisfaction surveys for auto and home claims. Policyholders frequently report high complaint ratios regarding adjuster communication.
• Safeco and Homesite: Ranked at the bottom of the J.D. Power's Best and Worst Home Insurance Companies property claims survey for customer satisfaction.

Why Insurers Deny or Delay Claims

• Cost-Cutting Software: Many large companies use internal computer programs to calculate lower settlement offers than what repairs or medical bills actually cost.
• Profit Focus: Consumer advocacy groups report that some insurers place corporate profit over paying valid policyholder claims.

Avoid "fly-by-night" ultra-budget insurers, carriers with persistent consumer complaint trends regarding delayed payouts, and stripped-down policy coverages that leave you financially exposed.

Companies and Categories to Avoid

• Fly-by-Night Budget Insurers: Companies like Fred Loya, BlueFire, and Mendota often feature very low upfront prices. However, personal injury attorneys and consumer reports note they frequently suffer from understaffed claims departments, poor communication, and automatic policy cancellations or lapses.
• Carriers with High Complaint Volumes: Major firms like Allstate and Liberty Mutual frequently appear at the bottom of consumer satisfaction indexes and draw criticism from legal professionals for utilizing aggressive claims-adjustment software or low settlement offers.
• Insurers Flagged for Slow Processing: National General, Safeco, and Farmers also surface in consumer data and regional studies for lower customer trust and slower payout communication.

Coverages to Avoid (or Reconsider)

• State-Minimum Liability Only: Choosing the absolute lowest legal limits saves money upfront but leaves you personally responsible if you cause a serious crash with expensive medical bills or property damage.
• Skipping Uninsured/Underinsured Motorist (UM/UIM) Coverage: Skipping this protection means you have no recourse for medical or repair costs if an at-fault driver has no insurance.
• High Collision Deductibles on Low-Value Cars: If your car is worth less than $3,000 to $5,000, paying for collision or comprehensive coverage often costs more than the vehicle is worth.
