Wells Fargo also defrauded 800,000 car loan customers and stole 25,000 cars

For borrowers, delinquencies arose quickly because of the way the bank charged for the insurance. Say, for example, that a customer agreed to a monthly payment of $275 in principal and interest on her car loan, and arranged for the amount to be deducted from her bank account automatically. If she were not advised about the insurance and it increased her monthly payment to, say, $325, her account could become overdrawn as soon as Wells Fargo added the coverage.

The report tried to determine how many Wells Fargo customers were hurt and how much they should be compensated. It estimated that the bank owed $73 million to wronged customers.

State insurance regulations required Wells Fargo to notify customers of the insurance before it was imposed. But the bank did not always do so, the report said. And almost 100,000 of the policies violated the disclosure requirements of five states — Arkansas, Michigan, Mississippi, Tennessee and Washington.
