The automaker said it had received 32 complaints of the front seat electric heater element overheating or leading to a fire. DaimlerChrysler spokesman Max Gates said the automaker knew of a few cases of injuries but did not have an exact number.
DaimlerChrysler does not know of any crashes resulting from the defect, Gates said.
The recall involves the 2003-2004 model years of the Grand Cherokee sport utility vehicle with heated seats.
Owners are expected to receive letters about the recall in July.
