Consumer Description

The Rear Window leaks when it rains on the truck. I brought it back to the GM Chevy dealer and they applied a sealant. it immediately leaked right after. the truck now smells musty and im assuming there is mold growth. it has been at the dealership for the past two weeks while they try to figure it out
