Two problems related to tailgate hinge have been reported for the 2002 GMC Envoy. The most recently reported issues are listed below.
In regard to my prior complaint I notice that my hinges holding my tailgate on were rusted about a month after I purchase my truck, and took it the dealer service shop. I was told that the hinges were not covered under the certified warranty,although according to the certified car and truck warranty it should have been notice during the bumper to bumper inspection before selling the truck. I can't remember the exact day I took it in I believe it was near the end of the month.
: the contact stated the electronic mirrors re-adjust without warning. The mirrors should maintain the last setting, but require re-adjustment every time the vehicle is driven. Occasionally the mirrors re-adjust while driving making it difficult to change lanes. The vehicle was taken to a service dealer twice for repairs. The dealer replaced the mirrors and made adjustments to the electrical unit. The problem was only alleviated temporarily by the repairs and the mirrors began malfunctioning again a year ago. . . . The mirrors will self adjust the settings. While driving the contact looked in the mirrors to change lanes and they were out of adjustment. Had to constantly adjust the mirrors prior to changing lanes. Also, when shutting the vehicle off, and restarted it, had to adjust the mirrors. The mirrors will not hold the set adjustment. In addition, the tailgate could only be opened with the remote, there was no other way to open the tailgate. In a situation where the contact's only exit from the vehicle was from the inside, could not open manually from the inside.
