The recall affects about 1,500 Gallardo Coupe and Spyder autos, from model years 2004 to 2006. The cars start at about $200,000.
Lamborghini says in documents sent to US safety regulators that pipes can corrode near the power steering pump. In rare cases, fluid can leak onto the hot engine and cause a fire. The company says it discovered the problem in product monitoring and testing.
No fires or injuries have been reported.
The cars were built from May 2003 through April 2008.
Owners will be notified this month. Dealers will update the power steering system free of charge.
