People who were mis-sold finance agreements when buying cars could face a delay to potential compensation payouts.
A decision by judges at the Court of Appeal has blown open an ongoing saga into hidden commission payments, with buyers possibly in line for payouts totalling billions of pounds.
Now the Financial Conduct Authority (FCA) is consulting on giving dealers extra time to deal with complaints.
However, lawyers say this could further delay compensation which should be paid to car buyers who may not have given their informed consent for the commission payments.
