What owners wrote

Crack in body seam above driver and passenger side of the tailgate AND underneath the roof rail cover caused water leakage. This resulted in a short of the power tailgate control module which draws down my battery and causes unexpected trunk closing during normal use. Family members have been hit in the head by the trunk due to the unexpected automatic emergency closing.
