Honda customers who inadvertently had their monthly car payment deducted twice this month should expect to see refunds appear in their bank account starting Thursday.
The automaker said the double-billing was a payment processing error.
Honda's customer-service phone lines were overwhelmed after the mistake.
Customers who couldn't get through on the phone posted on Twitter and Facebook in frustration.
In a Facebook post, Honda also said any overdraft fees would be waived or reimbursed.
