Honda said it will expand a March headlight recall to include 820,000 model-year 2002-2003 Civic sedans and model-year 2004-2005 Pilot sport-utility vehicles in the United States.
Honda dealers will inspect and, if necessary, replace components of the headlight wiring system.
The automaker said a problem with the wiring of the headlight switch could cause the low-beam headlights to not work. The loss of headlights could limit a driver's ability to see the road and potential hazards and increases the risk of a crash. However, Honda said no crashes or injuries have been reported in connection with the problem.
In March, Honda recalled 550,000 CR-V small SUVs from the 2002 through 2004 model years and Pilots from 2003 because of the same problem.
This was the second large expansion of a Honda recall this week.
On Monday, Honda said it would expand a recall of Acura TL sedans to include 572,000 model-year 2003-2007 Accord V6 vehicles in the United States.
But the automaker said the Accord recall, to fix leaking power steering hoses that could cause fires, will be delayed into next year because the automaker doesn't have enough parts to fix the problem. The updated power steering hoses won't be available until early 2013.
Honda is sending out a notice to Accord owners telling them of the problem and describing the symptoms. Drivers who think their cars are affected should take them into the dealership for an "interim" repair, the automaker said. The most commonly reported symptom is a smell from the seeping fluid.
