Hyundai has expanded its recall of the Veloster.

In December, the automaker issued a recall of more than 13,000 Veloster hatchbacks from the 2012 model year. The company says the panoramic sunroof can shatter and cause injuries.

Hyundai is now adding 6,100 more Velosters in the U.S. to the recall.

At least five people have suffered minor injuries from the sunroofs shattering.

Hyundai says the assembly of the sunroof may have been weakened during installation.
