Fiat Chrysler Automobiles admitted in a filing this week that it missed deadlines to notify customers in five separate safety recalls, which could mean a hefty fine from safety regulators in the U.S.

Back on May 18, the U.S. Department of Transportation sent FCA a special order demanding the company provide information on its recent recall performance.

The automaker confirmed in an 18-page document sent to the National Highway Traffic Safety Administration on Monday that it exceeded the legal 60-day limit of notifying owners of new recalls in five recent campaigns, according to USA Today.

NHTSA said a scheduled July 2 hearing into 20 different recall delays affecting 11 million vehicles is still on despite the admission. FCA was hoping the information it provided would be enough to cancel the hearing, to no avail.

"The goal of the public hearing is to consider their evidence, but also to consider the evidence and experience of people who own those vehicles," said Deputy NHTSA Administrator David Friedman, according to The Associated Press.

The 20 recalls cited by the safety agency include ones over faulty Takata air bags, ignition switches, gas tanks and loss of steering control.

Four of the five recall misses were by four days or less, but one was 12 days late. Four of the recalls took place in 2014, and one was from earlier this year.

There is a chance the safety agency could hit FCA with a fine of up to $35 million though it will all depend on how the big hearing goes next month.

In its 18-page document, the automaker acknowledged its mistakes and outlined changes it has made in order to "increase recall completion rates," according to the AP report.
