Dec 23 (Reuters) - Stellantis ( STLA ) unit FCA US

agreed to pay $4.2 million to resolve a California investigation

into excess emissions, the state said on Monday.

The California Air Resources Board (CARB) said the vehicles

covered by the settlement include 2014 through 2016 Ram

ProMaster 1500, 2500 and 3500 vehicles equipped with 3.0L diesel

engines.

The state said the vehicles had an unapproved device that

circumvented emissions control and resulted in nearly 55 tons of

excess oxides of nitrogen being released into the air.

Stellantis ( STLA ) in 2022 paid a $5.6 million settlement for similar

allegations involving gas-powered vehicles.
