One problem related to transmission not engage has been reported for the 2003 GMC Envoy. The most recently reported issues are listed below.
The gear shift selector cable became disengaged from the transmission while backing out of a parking spot. According to my mechanic, there is a small plastic bushing that became brittle and fell off causing the failure of the cable to maintain a connection with the transmission. This caused my transmission to become locked in the park position and unable to be moved into any other drive. While I was in a safe location, I'm concerned that other drivers in similar situations will become stranded in locations that are not safe. I conducted a recall search and found that this item has not been recalled. I placed a call to general motors and lodged a complaint. According to gm, they have received a number of complaints about this issue but are not issuing a recall at this time. I asked gm to provide me the number of complaints they have received about this and they declined to give me that information. I am seeking to file this complaint, have it reviewed, and determine whether a recall should be issued for this vehicle.
