A class action lawsuit against Shell was authorized for consumers in Québec on July 18, 2003.
From March 2001 to March 2002, Shell included an additive to its regular-grade "Bronze" gasoline that allegedly damaged the fuel supply system of many vehicles. Shell estimated that between 100,000 and 200,000 consumers bought "Bronze" gas during that period; the exact number of adversely affected vehicles remains unknown, however the number of incidents reported is highly significant. The most commonly damaged vehicles are from the Acura, Chrysler, Dodge, Ford, General Motors, Hyundai and Volvo brands.
In July 2004 the Superior Court of Quebec approved a settlement in the class action filed on behalf of consumers who purchased regular-grade Shell gasoline from early 2001 to early 2002. The settlement completed the voluntary reimbursement program undertaken earlier by Shell Canada. The closing date for claims in the Shell class action was November 5, 2004.
