Three problems related to tailgate latch have been reported for the 1999 GMC Sierra. The most recently reported issues are listed below.
Repeated abs brake failure. This has not been corrected despite numerous attempts to repair problem(s). Heater motor malfunction, repeated wiper arm replacement, tailgate handle malfunction.
1999 GMC Sierra 1gtek19tsxe504480 tailgate cables breaking. Replaced first cable just after warranty ran out. I should have replaced both cables at that time. Some time later I replaced both cables. These only lasted a very short time. At the present time I have one cable broken and the one left is streched to the breaking point. I had one incident of the tail gate falling off. I feel buying more cables from gm is a waste of money. The incident date is a guess.
I complained to GMC directly about abs failure and reported it to atty. Gen of nys. I was told its normal wear in states with salt, funny that the paint is good to this day.
