One problem related to engine stall has been reported for the 2003 Chevrolet Suburban. The most recently reported issues are listed below.
My Suburban goes to reduced power unexpectantly and the engine will stall causing a loss of power steering and control of the vehicle. My Suburban has been taken in to the dealer I purchased the vehicle from on five occasions and the dealer is unable to fix the problem. . The most recent time was 9/1/2011. It went to reduced power 10 miles after leaving dealership and stalled as I pulled out into traffic from a restaurant. A number of cars had to brake excessively and swerve around me until I could angle my Suburban off the road without power steering. The truck weighs 6700 lbs and I needed all my strength to turn the wheel enough to get off the road. I am fearful about driving my Suburban and the high probability of injury to myself or others.
