New York (CNN Business) Fiat Chrysler will pay about $800 million to settle charges that its diesel vehicles sold in the United States had improper software that allowed it to violate emissions rules.

The Justice Department and EPA announced the settlement Thursday morning. Fiat Chrysler will pay about $400 million in civil fines to different federal and state agencies. The company also reached a $280 million settlement with the owners of 100,000 diesel-powered Jeep SUVs and Ram pickup. Fiat Chrysler will pay them up to $2,800 per vehicle.

The vehicles involved in the settlement are the 2014, 2015 and 2016 model year Jeep Grand Cherokee SUVs and Dodge Ram 1500 trucks with 3-liter diesel engines. To receive the payments, the car owners will have get their cars repaired. If Fiat Chrysler doesn't get at least 85% of the vehicles brought in for repairs, it will face additional fines.

The added costs beyond the fines and payments to vehicle owners are for various mitigation efforts to curb emissions, and for future warranty costs.

"Today's settlement sends a clear and strong signal to manufacturers and consumers that the Trump administration will vigorously enforce the nation's laws designed to protect the environment and public health," said Acting EPA Administrator Andrew Wheeler. He said not only did Fiat Chrysler break the law but that it worked to hide its conduct.
