Using complaint and exposure data from the California Department of Insurance, we calculated the justified complaint ratio for auto insurance companies in California. We've listed them from the best (lowest complaint index) to the worst (highest complaint index). If a company has an index of 1.05, then that means it has a 5% higher share of complaints compared to its share of underwriting exposure.

I was with Liberty Mutual for about 15 years and was very satisfied with their prices and service, although I never filed a claim. When I retired and moved from California to Florida, my auto rate went up a ridiculous amount, to almost $10,000 a year even though I had no accidents and one minor moving violation in the last ten years. On top of that, Liberty Mutual screwed up my umbrella policy and told me it was “unenforceable,” whatever that means, but I had to pay for the policy anyway up to the time I canceled and switched to Progressive, which cost about one third the cost of Liberty Mutual for an identical policy. Even good companies change over time.
