Eight problems related to power train have been reported for the 2003 GMC Envoy. The most recently reported issues are listed below.
Shift cable broke between the shifter and the transmission while shifting from drive to reverse to park on a street. If this had happen while shifting down gear to lower speed while driving down a hill, a loss of control of the vehicle would have happen that would have led to a crash with extreme property damage and most likely driver and passenger injury and possible death. The vehicle was towed to ourisman Chevrolet in marlow heights maryland for repair after the tow truck driver manually shifted the transmission into drive from underneath the vehicle that would've been extremely dangerous for the tow driver to do if the vehicle had been facing down hill or in a heavy traffic situation. For some reason, however, my vehicle still hasn't been repaired nor have I've been given a reason as to why.

This is the second occurrence of an issue with the vehicles manual switch for 2hi,awd,4hi,4low. The dealer I bought the used vehicle from fixed the issue right after purchase and I'm having another problem with the switch. I try to select anything besides 2hi and the selector will just continue to blink on the selection without any action. Sometimes the service 4wd will illuminate on the dash. This seems like a frequent occurrence/complaint of other Envoy owners online.
