The software used in the diesel engines of the Suzuki Vitara and the Jeep Grand Cherokee seems to be messing with the vehicles emission data, the Dutch service for road traffic RDW said in an intermediate report on investigations done into 16 different vehicles. Both these cars' engines are made by Fiat Chrysler, NU.nl reports.
In both cars the system that reduces nitrogen oxide emissions turns off for no apparent reason, according to the RDW. The Public Prosecutor was informed of these results. A criminal investigation may follow.
