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.
The best car insurance companies have a few things in common: They have straightforward shopping experiences, take good care of policyholders after a crash and treat their customers with respect and courtesy. That means only insurers with high customer satisfaction scores and relatively few complaints to insurance commissioners make it to the top of our list of the best auto insurance companies.
