What drivers actually complain about to insurance regulators

Drivers complain to state insurance regulators mostly about claims: slow responses, denials, and settlement offers that seem too low. Pricing, cancellations and nonrenewals come next, with sales and agent conduct a smaller share. Where states publish the breakdown, claim handling is the largest group by a wide margin, and several of the problems it covers can be reduced before a claim ever happens.

Few shoppers look past a company's overall complaint number to the reasons behind it. The reasons are more useful, because they show where the relationship between insurer and customer tends to break.

How regulators sort complaints

Every state keeps its own complaint records, but most follow a common structure that traces back to the NAIC's model regulation on complaint records. The 1992 version of that model tells insurers and departments to classify each complaint by the function of the company involved and by the nature of the complaint. It names four functions, plus a miscellaneous one:

The model also asks for a disposition (it gives examples such as corrective action taken, no action deemed necessary, or a satisfactory explanation given to the complainant), the line of insurance, the dates received and closed, and the state of origin. It also records the license number of any agent or adjuster involved. Notice that a complaint is classified by "function(s)", plural; one complaint can touch more than one.

Modern state systems are more detailed. Missouri's Department of Commerce and Insurance, in its 2022 complaints report (published July 2023, covering 2020 to 2022), breaks private passenger auto complaints into four groups. Claim Handling includes adjuster handling, claim delay, claim denial, unsatisfactory settlement or offer, subrogation and fraud. Marketing covers items such as misleading advertising and misrepresentation. Policy Service covers delays or no response and billing issues. Underwriting covers cancellation, nonrenewal, premium and rating, surcharges, credit reports, CLUE reports and refusal to insure. That four-way split is what most readers will find in their own state's report.

Claim handling: the largest group

Where the data are published, claim handling leads, and the margins are large.

• Kansas, 2024. The Kansas Department of Insurance's 2024 complaint index report says 67 percent of its complaints concerned claims handling, with 18 percent about policyholder service, 10 percent underwriting and 5 percent marketing and sales. That figure covers all six major lines, not just auto, and automobile was the largest line at 32 percent of complaints.
• Washington, 2023. The Office of the Insurance Commissioner reported that auto complaints rose from 2,216 in 2020 to 3,276 in 2022, and that claim handling was cited in more than 80 percent of complaints as of May 15, 2023, a record figure, in its June 2023 announcement. Its examples included denials without a suitable explanation, delays in hearing back from insurers, and app-based repair estimates well below final costs.
• Arizona, fiscal 2025. Arizona's Department of Insurance and Financial Institutions closed 4,077 insurance complaint cases and healthcare appeals. According to Insurance Journal's summary, about 60 percent of consumer complaint cases were personal lines, and the top reasons were claim handling (adjuster handling, delays, denials and unsatisfactory settlements), premium and rating, and policy cancellations and nonrenewals.

The three states differ in year, scope and counting, so do not compare the percentages across them. What they share is the order.

The three claim complaints behind the headline

Delay. The insurer takes too long to acknowledge a claim, inspect the car, issue an estimate, decide coverage or pay. Time limits come from state claims-practices laws and regulations, and they differ; see how fast an insurer must respond to your claim: state time limits and unfair claims practices acts: the deadlines insurers must meet. For orientation, the NAIC's Model Regulation 902 contemplates acknowledging a claim within 15 days, but a state's own rule controls.

Denial. The insurer says the policy does not cover the loss, an exclusion applies, or the policy was not in force. Many denials are legitimate. Complaints arise when the explanation is thin, cites no policy provision, or rests on a fact the policyholder disputes. Our guides on why car insurance claims get denied and how to read a car insurance claim denial letter explain the common grounds.

Unsatisfactory settlement or offer. The insurer agrees the loss is covered but the amount is too low. For a total loss, the dispute is usually the valuation; for a repair, it is the estimate versus what the shop says is needed. Related reading: how a car is declared a total loss: formulas and state thresholds and when the shop charges more than your insurer will pay.

A fourth subtype deserves mention: complaints about the claim process itself, such as repeated requests for the same documents, an adjuster who does not return calls, or confusion over who is authorized to speak for the insurer. The model regulation's separate "claims procedure" and "policyholder service" reasons capture these.

Premium and rating complaints

Arizona's second-ranked reason is premium and rating, and Missouri lists it under underwriting. These complaints are about price at sale or at renewal: a renewal increase the customer did not expect, a surcharge for a violation or claim, a quote that changed between the online estimate and the issued policy, or a rating factor the customer thinks is wrong (such as a vehicle garaging address, driver list or mileage).

A regulator's power over an individual policy is narrower than many complainants expect. A department can check whether the insurer applied the rates and rules it filed, and whether a surcharge or credit was applied as the filing says. It reviews filed rates in general, but a complaint about one policy does not usually lower the price just because it seems high. Why prices move is covered in how car insurance rates are calculated and from filing to your bill: the timeline of an auto rate increase.

The most useful complaints in this category are about application, not level: "my policy shows a driver who moved out," or "a ticket outside the lookback period was surcharged." Those are checkable.

Cancellation, nonrenewal and underwriting

This group covers an insurer ending a policy (policy cancellation mid-term, nonrenewal at the end), refusing to insure, or issuing the policy on terms the customer did not expect. It includes non-payment cancellations, which are among the most avoidable: a payment that bounced, an autopay card that expired, a notice sent to an old email address.

The regulator checks whether the insurer followed the state's notice rules and used a permitted reason. Notice periods and permitted reasons are state-specific. For one common trigger, see Nonrenewal after a ticket or DUI: your rights and next steps. A cancelled policy also creates the problem described in claim denied because your policy was cancelled or lapsed.

Agent and sales conduct

Marketing and sales complaints are the smallest group in the Kansas data (5 percent in 2024), but they can be the costliest per case. Typical issues are an agent who said a coverage was included when it was not, a policy bound for a lower limit than the customer asked for, a premium financed or collected in a way the customer did not understand, or an unlicensed seller. Licensed agents are regulated separately from insurers, and you can confirm one using how to verify an insurance agent's license and the insurer.

Complaints about the company versus its people and vendors

A complaint is often filed against "the insurer" when the conduct belongs to someone else, and the distinction matters.

• The insurer is responsible for claim decisions, rate application, and the terms of the policy.
• An agent or producer is responsible for what they said or did at sale. Captive and independent agents differ in whose agent they are; see captive agents vs independent agents vs buying direct.
• An adjuster, staff or independent, handles the investigation and the estimate. The NAIC model's record asks for the license number of any agent or adjuster involved, because departments license individuals as well as companies. Missouri lists "adjuster handling" as its own claim reason.
• A vendor or tool, such as a photo-estimate app or a valuation service, produces a number the insurer then adopts. Washington's examples of app-based estimates below final costs illustrate this. The insurer is still accountable for the outcome, but the fix is often a request for a re-inspection; see photo estimates and virtual appraisals: how accurate are they?.
• A repair shop or rental company is a separate business. A department that regulates the insurer may have no authority over a shop's work, which is covered in bad collision repairs: who is responsible when the work is wrong.

When you file, name the entity and the person if you know them, and say what each did. A complaint that says "the adjuster has not called in 12 days" is easier to act on than "terrible service."

What happens to a complaint

Regulators treat a complaint as a formal written communication, not a call. In Kansas, the department notifies the insurer and any agents, sends a copy, asks for a review and explanation, and requires the company to respond within 15 business days, according to its 2024 report. What the department concludes is then recorded.

Two measures describe the result.

Confirmed (or justified) complaints. The NAIC's closed, confirmed complaint data count complaints where the department found a violation of law, regulation or policy terms, or where the complaint and the company's response together show the company was in error. This is the definition Kansas quotes from the NAIC. The NAIC publishes closed confirmed complaints by reason and by disposition, which shows how complaints were resolved. The share of complaints that end up confirmed varies by state and year, so look at your own state's figure rather than a national average.

Consumer relief. Missouri reports the percentage of complaints resolved with consumer relief by line. For private passenger auto it rose from 34.9 percent in 2018 to 46.1 percent in 2022. That is a measure of outcome, not fault: relief can mean a claim was paid, reconsidered or corrected after the department got involved. Kansas reported $12,491,218.32 recovered for consumers across all lines in 2024.

What this tells you: a complaint is not a verdict, and many complaints are resolved by getting a stuck process moving. Also, a complaint that is not confirmed may still have been worth filing, since the insurer must respond in writing. For the process, see how to file a complaint against a car insurance company and after you file a department of insurance complaint: what to expect.

Practical lessons: heading off the common problems

The aim is to prevent the trouble the data show, without assuming your insurer will behave badly. Use this sequence.

1. Pay attention to the payment path. Put the renewal and billing dates on a calendar, confirm autopay works and note the grace period in your policy. Non-payment cancellations are the easiest complaint to avoid.
2. Read the declarations page at purchase and each renewal. Confirm drivers, vehicles, garaging address, limits and deductibles. Mismatches here become premium complaints and coverage disputes later.
3. Get promises in writing. If an agent says a coverage is included, ask for the endorsement or a written confirmation.
4. Know your valuation rights before a total loss. Keep service records and photos so you can support the value; see how to read a total loss valuation report line by line.
5. Report claims promptly and keep a log. Note dates, names, and what was said. If an insurer misses a state deadline, the log is your evidence.
6. Ask for the denial or low offer in writing, with the policy provision. Thin explanations are the seed of denial complaints.
7. Escalate inside the company first when it is quick. escalating a problem inside your insurer before you complain covers that; but a regulator complaint does not require you to wait if deadlines are being missed.
8. Know when to go to the department. If there is a clear violation, a missed deadline or a refusal to explain, file.

Questions worth asking your insurer or agent

• "If my car is a total loss, how do you value it, and will I see the valuation report?"
• "What happens if the shop finds more damage after your estimate?"
• "How many days do I have to pay before the policy cancels, and how will you notify me?"
• "Which of my discounts depend on information that could change, such as mileage or garaging?"
• "Who is my contact for the claim, and what is the process if they are unavailable?"

Reading complaint data without being misled

A few cautions apply whenever you use complaint figures to compare companies.

• Counts versus ratios. Large companies receive more complaints in absolute terms. Indexes compare complaint share with premium share; an index of 1.00 means the two are equal, as explained in The NAIC complaint index: how to look up an insurer.
• Small numbers swing. A tiny insurer with three complaints can look worse than a giant with thirty. See the small-numbers problem in insurer complaint ratios.
• Reasons matter more than the total. A company with few complaints that are all about claim denials is a different risk from one with many complaints about billing.
• Not all dissatisfied customers complain. Complaints are a floor on dissatisfaction, which is why satisfaction surveys are a useful complement.
• Year and state. Compare like with like, and check the year in the report.

Common questions

Which complaint reason is most common for car insurance?

In the state reports reviewed here, claim handling. Kansas put it at 67 percent of complaints across lines in 2024, Washington reported it in more than 80 percent of auto complaints in 2023, and Arizona named it the top reason in fiscal 2025.

Can a regulator make my insurer pay a claim?

A department can require the insurer to respond, review its decision and correct violations of law or policy terms, and many complaints end with the claim reconsidered. It does not act as a court. Disputes over facts or value may end in the policy's appraisal process or in litigation; a licensed attorney is the place for specifics.

How long does a complaint take?

It varies by state and by how complicated the dispute is. The one deadline in the sources reviewed here is Kansas's: the insurer must respond to the department within 15 business days of being notified. Resolution of the underlying problem can take longer, so ask the department for its typical timeline when you file.

Is a company with zero complaints safe?

Not necessarily. A zero can mean few customers in that state or customers who did not file. Check the premium volume behind the figure and use other sources as well.

Key takeaways

• In state complaint data, claim handling is the largest group: delay, denial and unsatisfactory settlement or offer.
• Premium and rating, cancellations and nonrenewals follow, then agent and sales conduct.
• Complaints can concern the insurer, an agent, an adjuster or a vendor; naming the right party helps resolve them.
• A confirmed complaint means the department found a violation or an error; many complaints are resolved without that finding.
• Most common problems can be reduced by tracking payment dates, checking the policy documents, getting promises in writing and keeping a claim log.
