One problem related to tailgate has been reported for the 2004 Toyota 4Runner. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Toyota 4Runner based on all problems reported for the 2004 4Runner.
The tailgate of the SUV opens it while driving. The tailgate clothing latch sounds as if it has closed, but has not. This results in the tail gate opening up while driving. This began after having a repair on the back window system, that was a recall from Toyota. Also, there's no protection from the edge of the tailgate rusting. I've been told this is in every Toyota 4runner from 2004. This has been a problem for many years for me, but I did not know that there was a way to report it.
