The Japanese arm of Volkswagen AG said Wednesday it has found 83 cases in which exhaust emissions and fuel economy data were improperly recorded for new cars since 2012 in another blunder for the German automaker that was previously wrapped up in an emissions test cheating scandal.

The latest revelation follows a number of similar cases at rival automakers, including Nissan Motor Co. and Subaru Corp. that admitted to falsifying emissions and fuel efficiency data during final vehicle checks.

Volkswagen Group Japan K.K. said out of 1,113 vehicles that were subjected to sample inspections conducted from 2012 to 2018, there were 83 cases in which employees wrongly recorded tests as valid even though they did not meet Japanese regulations for speed and humidity test conditions.
