One problem related to brake light has been reported for the 2001 Chevrolet Express. The most recently reported issues are listed below.
A Chevrolet Express/explorer limited se caused serious issues on the highway for me and 4 other drivers (that I witnessed). . Brake lights are so high off the ground, they are not detectable! I almost slamed into the back of this van 5 times before I could get around it. I could not tell when the van was slowing or stopping. This is a serious misjudgment in engineering. Those lights are easily 4 foot about the height of an 18 wheelers. No one is accustom to looking that high up for brake lights.
