Honda Motor Co <7267.T> said on Friday it would recall a total 646,000 units of the Fit/Jazz and City models globally, including 140,000 in the United States.

The recall covers the models sold in North America, South America, Europe, South Africa and Asia, but not Japan, a spokeswoman said.

The Fit is Honda's best-selling model in Japan.

Honda said the recall was to fix a defective master switch, which could cause water to enter the power window switch and in some cases cause a fire.

There were three reported cases of fires due to the defect, two in the United States and one in South Africa, the spokeswoman said.
