One problem related to door hinge has been reported for the 1999 GMC Jimmy. The most recently reported issues are listed below.
My 1999 GMC Jimmy has been given us problems shutting the drivers and passengers doors. It leaked in the car wash or when raining as the doors did not properly close, and now they didn't close at all. I must spend $300 , not in my budget so will get behind with bills, to have the pins and hinges replaced as they were made with nylon , but the replacementwas made of brass. I had to pay already to have the door fixed to close. I tell my son to fasten his seatbelt and stay away from the door as even if it locked. I was afraid it might open.
