When automakers issue a recall, they must effectively alert their customers to bring in their vehicles for repair. But that doesn’t always happen.

The National Highway Traffic Safety Administration (NHTSA) has raised concerns about the slow pace of repairs on 20 recalls involving some 10 million Fiat Chrysler vehicles. The NHTSA has scheduled a public hearing on July 2, 2015 to determine whether the company has failed to remedy safety defects and issue required notices.

“NHTSA has concerns about slow completion rates, slow or inadequate notifications to consumers, faulty remedies, improper actions by dealers and more,” NHTSA Administrator Mark Rosekind said during a press conference yesterday. “Each of these defects presents an unreasonable risk to safety and in each case there is reason to question whether Fiat Chrysler has met its legal obligations.”

For example, in 2013, more than 50 deaths were attributed to the automaker’s Jeep SUV. Jeeps with rear-mounted gas tanks are vulnerable to explosions upon collision. After initially refusing to recall the vehicles, the automaker eventually recalled 1.56 million Jeeps in the summer of 2013. But by the end of 2014, only 3 percent of the vehicles had been repaired. NHTSA issued a special order to Fiat Chrysler ordering the company to provide information on its recall performance.

“Any auto defect that compromises the safety of our driving public is unacceptable,” said U.S. Transportation Secretary Anthony Foxx in a press release. “Auto manufacturers are obligated to effectively remedy safety defects when they are discovered, and if they fail in that responsibility, we are obligated to act."
