Wells Fargo denied wrongdoing but settled to avoid the risks, cost and distraction of litigation, court papers show.
The bank had no immediate comment on Friday. Lawyers for the customers did not immediately respond to requests for comment.Wells Fargo has been beset since September 2016 by a series of scandals over how it treats customers, including wrongly charging an estimated 600,000 auto loan borrowers for insurance when they already carried auto insurance of their own.
In April 2018, Wells Fargo agreed to pay $1 billion to the Consumer Financial Protection Bureau and Office of the Comptroller of the Currency to settle U.S. probes of the San Francisco-based bank's auto insurance and mortgage practices. Subsequently it was fighting to exclude some of the 600,000 loan recipients from a payout.
The bank was still smarting from a prolonged scandal in which bank employees created millions of fake bank accounts in customers' names.
Wells Fargo is taking steps to rebuild customer trust, but remains unable to expand under restrictions imposed in February 2018 by the Federal Reserve until the bank, now the nation's fourth-largest by assets, cleans up its culture and oversight.
Thursday's proposed settlement covers Wells Fargo customers charged for "collateral protection insurance" between Oct. 15, 2005 and Sept. 30, 2016.
The complaint said Wells Fargo's wrongful practices caused nearly 275,000 customers to become delinquent, and nearly 25,000 vehicles to be illegally repossessed.
Through Thursday, Wells Fargo's share price had been little changed since the scandals broke, while the KBW Nasdaq Bank Index had risen 33 percent.
The case is In re Wells Fargo Collateral Protection Insurance Litigation, U.S. District Court, Central District of California, No. 17-ml-02797.
