Four problems related to transmission failure have been reported for the 1997 GMC Jimmy. The most recently reported issues are listed below.
Ignition switch has failed and been replaced twice in past 4 years (10/2000 & 8/2003). When it fails, the transmission fails to shift properly and the vehicle loses power and/or stalls. This creates a very dangerous situation, especially if you are in heavy traffic with your entire family. I have been told by gm technicians that this is a common problem due to poor design, engineering and mfg quality.
Transmission failed on interstate and the emergency flashers failed, transmission has been replaced on two occasions, the electrical system experiences continual malfunctions (emergency flashers, brake lights, warning buzzer).
