High underhood temperatures that could damage the alternator and cause a fire have prompted Mercedes-Benz USA LLC to recall SLR McLaren sports cars from the 2005 and 2006 model years.
The problem occurs under "hard operating conditions," Mercedes-Benz said Monday. The automaker does not have any reports of engine fires caused by the problem, a spokesman said.
Mercedes-Benz said the recall covers 433 vehicles in the United States.
An alternator damaged by heat will not provide enough power for the vehicle's electrical systems. If the problem occurs, the vehicle's computer control system will warn the driver and shut down convenience features such as the air conditioning and radio.
Mercedes said dealers will fix the car by improving engine compartment cooling and by installing a new alternator and a modified engine control unit.
