DETROIT (AP) — The U.S. government’s highway safety agency says it will hold a public hearing in July to determine if Fiat Chrysler has met its legal obligations in 20 safety recalls.

Witnesses and the automaker will be able to present evidence at the July 2 hearing by the National Highway Traffic Safety Administration.

If the agency finds that Fiat Chrysler failed to fix safety defects, it could take action that includes ordering the company to buy back or replace vehicles.

Also, the agency ordered Fiat Chrysler to provide information on the pace of repairs of several recalls.

The agency has been feuding with the company over the recall of 1.56 million older Jeeps with gas tanks positioned behind the rear axles, making them susceptible to fires.
