Four problems related to ignition switch have been reported for the 1997 Oldsmobile Bravada.
Bravada shuts down while driving. While on highway I was traveling at 70 mph. Then the truck is completely dead. I was able to pull over and sat for 5 to 10 minutes trying to restart it. It finally started. (no check engine light came on) after I let it sit for a few month I decided to replace the egr valve gasket and clean the carbon out of the throttle body. A few months go by I was driving on a road off of a high way going 40 mph. Same thing occurred. I got it started in the same amount of time and it will run fine like nothing ever happened. After reading the other complaints I am going to replace the ignition switch even though the dealer said it could be numerous of other things and not the ignition switch. In fact they never heard of an ignition switch doing this.
My 1997 Oldsmobile Bravada had a problem where the car would "die" anytime and then outomatically turn back on while driving on the highway. The same would happen during city driving but I wiould have to re-start the car. A very dangerous occurrence if I was in the middle of making a turn when the car would suddenly stop. It turned out to be the ignition switch that needed replacement and the dealer said that this was becoming a very common problem with this kind of automobile (bravada, blazer, jimmy). I was fortunate not to have had an accident before I turned into the dealership.
The vehicle was serviced at least four times for stalling and cutting off. The ignition switch was replaced.
The engine shut down on several occasions, consumer was informed there was an internal problem with the ignition switch.
