Mercury Car Insurance Review

Mercury Insurance is a California-centered budget-value personal-auto specialist sold only through independent agents, with publicly traded parent Mercury General Corporation (NYSE: MCY). The CA-centric footprint, the IA-only distribution, and the 2024-2026 California regulatory environment (Sustainable Insurance Strategy, January 2025 LA-area wildfires, 2026 Safeco wind-down absorption) together make Mercury materially different from mass-market national competitors. Modeled California rates frequently beat the CA state average; the trade is an 11-state footprint and no direct-channel buy. AM Best FSR A (Excellent); confirm the current rating action date against news.ambest.com before signing.

MercuryGO (telematics)

MercuryGO is Mercury's smartphone-based telematics program. The app tracks hard braking, hard acceleration, speed, phone use while driving, time of day driven, total mileage Mercury publicly describes MercuryGO as a discount program. In California specifically, Proposition 103 restricts behavior-based premium rating in the mold used by competitor two-way UBI programs, so a MercuryGO-driven surcharge is not permitted on the CA book. State-by-state program mechanics are governed by filed rate manuals with each state's DOI; confirm per-state rules at enrollment before relying on the discount-only framing for your specific state.⁵

• Enrollment discount: participation discount at enrollment⁵
• Max renewal discount: renewal discount based on measured driving score⁵
• Can it raise your rate? MercuryGO is reported as a discount-only program; the headline savings are the only published outcome. Confirm your state's rules at enrollment.⁵

Pricing

Every Mercury quote is personal. What follows are modeled premiums for defined driver profiles from reputable publisher analyses — not personalized quotes. Use them to calibrate what to expect, not to replace a real quote in your state.

How to read these numbers. Different publishers model different profiles and may use different underlying data (Quadrant Information Services is the most common dataset). Your quote depends on your driving record, credit-based insurance score where allowed, vehicle, garaging ZIP, mileage, prior insurance history, age, household composition, telematics participation, and the coverages and deductibles you select.

Complaints and regulatory record

The National Association of Insurance Commissioners publishes a complaint index that normalizes complaint counts against a company's share of premium written. A value of 1.0 represents the baseline expected complaint volume for a company of that size; lower is generally better.

Mercury writes personal auto through four rated entities. California DOI regulatory actions and complaint data are the primary YMYL signal for a CA-centered carrier; pull current California DOI company profile data and per-entity NAIC CIS values before signing.⁸

To look up the current complaint index for the specific Mercury underwriting entity that writes policies in your state, use the NAIC Consumer Information Source or your state Department of Insurance. The entities most commonly rated for Mercury are:

• Mercury Casualty Company
• California Automobile Insurance Company
• Mercury Insurance Company
• American Mercury Insurance Company

Complaint index measures regulator-filed complaints, not overall service quality; treat it as one input among several. Index values vary by underwriting entity and by state and can shift year over year, so pull the current number for your state before signing.

Financial strength

AM Best affirmed Mercury at Financial Strength Rating A (Excellent) and Long-Term Issuer Credit Rating a (Excellent) on February 24, 2026 with a stable outlook³. AM Best affirmed Mercury Casualty Group members at FSR A (Excellent) and ICR "a" (Excellent) on February 24, 2026, with outlooks REVISED TO STABLE from Negative. Mercury General Corporation Long-Term ICR affirmed at "bbb" (Good). AM Best cited that LA wildfire net losses were materially lower than feared ($380M net against a $2.4B policyholder surplus; $362M surplus increase year-over-year) and that reinsurance uncertainty had been resolved. Supersedes the interim February 20, 2025 outlook revision to Negative over LA wildfire exposure. California market concentration and the state Sustainable Insurance Strategy remain the key rating-pressure factors in secondary coverage.

What these ratings mean and do not mean. A high financial-strength rating indicates the insurer has the resources to pay claims under a wide range of adverse scenarios. It is not a guarantee of any specific claim outcome, service quality, or price competitiveness in your quote. Ratings can change; check the affirmation date.

• Safeco California personal-lines wind-down absorbed into IA channel (January 2026): Liberty Mutual retired Safeco effective April 25, 2026 and non-renewed CA non-good-driver auto starting January 1, 2026.
