DETROIT (AP) - Fiat Chrysler is back in hot water with U.S. auto safety regulators.

DETROIT (AP) Fiat Chrysler is back in hot water with U.S. auto safety regulators.

The National Highway Traffic Safety Administration says the company under-reported deaths, injuries and other information to the agency as required by law.

The agency says a preliminary inquiry found a number of problems with Fiat Chrysler's system for gathering and reporting data.

Automakers have to report injuries and deaths so the agency can spot trends and investigate auto safety problems.

Fiat Chrysler says it found the problems and notified the agency. The company says it's cooperating.

The government says it will take appropriate action after gathering more information.

In July, the safety agency slapped FCA with a record $105 million penalty for violating laws in a series of vehicle safety recalls.
