Collective proceedings against Renault SA and related parties over emissions defeat devices in dCi diesel engines, following findings by French authorities of "exceptionally high" real-world NOx emissions.
Following the April 2024 ruling allowing the Car Claim Foundation to act as litigant, the Emissions Justice Foundation's parallel proceeding against Renault is progressing through case management. Mercedes-Benz and Renault both raised admissibility questions which the court rejected in 2024.
Renault, Dacia or Nissan vehicles with the 1.5 dCi engine, manufactured between 2009 and 2019.
Engine · 1.5 dCiLarger Renault and Nissan vehicles with the 1.6 dCi engine.
Engine · 1.6 dCiRenault Trafic, Espace, and larger commercial / passenger vehicles.
Engine · 2.0 dCiIn January 2017 the French DGCCRF (consumer protection authority) referred Renault to the public prosecutor following findings that Renault diesel vehicles emitted NOx at levels far above type-approval limits in real-world conditions. The DGCCRF’s report identified what it described as a ‘general’ strategy of engine calibration designed to pass test conditions while emitting substantially more NOx during normal driving.
The DEJF alleges that Renault SA, with the knowledge and participation of its Alliance partner Nissan and its Dacia subsidiary, equipped diesel vehicles with defeat-device strategies and consequently engaged in consumer fraud.
Following the Amsterdam District Court’s April 2024 ruling allowing the Car Claim Foundation to participate as a litigant in parallel proceedings, the foundation’s case against Renault is advancing through case management. We expect substantive briefing to continue through 2025–2026.
