Dutch prosecutors said on Monday they will look into possible misuse of emissions software by Suzuki (7269.T) and Fiat Chrysler's (FCHA.MI) Jeep.
The announcement followed a report by the Dutch road authority earlier on Monday, which found that the Jeep Grand Cherokee and Suzuki Vitara had unacceptably high levels of toxic emissions.
The RDW said in a statement its tests of more than a dozen car makers since the Volkswagen emissions scandal singled out Jeep and Suzuki, adding that other manufacturers were not found to have violated regulations.
