DETROIT (AP) — Subaru is recalling nearly 634,000 cars and SUVs in the U.S. because lights beneath the doors can overheat and catch fire.

The recall affects all Outback and Legacy cars from model years 2010 and 2011. Also included are Tribeca SUVs from 2006 through 2012 and Forester SUVs from 2009 through 2012. Subaru says the Tribecas and Foresters were sold before January 2012.

The company says moisture can get into puddle lights beneath the doors and cause a short circuit that can melt plastic and cause fires. It says only 54,000 of the vehicles are equipped with the lights and will need to be repaired. But it will send letters to all owners asking them to take their cars to dealers if they have the lights.

Subaru said Thursday that there have been no crashes or fires because of the problem. The company found the problem after getting complaints about smoke coming from the lights on a small number of vehicles.

The National Highway Traffic Safety Administration says on its website that Subaru will install an additional fuse at no cost to the owners. The recall is expected to begin in February.
