One problem related to engine failure has been reported for the 2003 Chevrolet Suburban. The most recently reported issues are listed below.
I have been experiencing complete engine failure while driving at highway speeds without any warning. I notice a loss of power and notice the engine light is on and the vehicle is difficult to steer. After coasting to the left side of the road, the vehicle igition is turned off and after several attempts, the car starts again and I can drive to my destination. Fuel pump and fuel ines were replaced less than 2 years ago when a similar problem was experienced.
