Has anyone that has test driven or owns a 4-cylinder Terrain or Equinox experienced rough engine / powertrain operation while in ECO mode? During our second test drive of a 4-cylinder Terrain the engine ran very rough when got into ECO mode and eventually stalled on us when we came to a stop. I think there were about 100 miles on the vehicle and there was at least a 1/4 of tank of fuel. Are there any TSBs out there regarding this issue?
