One problem related to tailgate latch has been reported for the 2004 Chevrolet Avalanche. The most recently reported issues are listed below.
I have experienced two separate incidences where upon acceleration the tailgate has dropped causing it to fall extremely hard on the rear bumper. One of the times we were on the freeway with heavy traffic causing us to immediately pull to the side of the road so our luggage did not fall out onto the road which would have caused an accident.
