Two problems related to power steering pump have been reported for the 1999 GMC Suburban. The most recently reported issues are listed below.
Door acuators faulty. Power steering pump replaced. Fuel guage faulty. Security system overrides starter which does not allow the vehicle to be started. We have had the vehicle "serviced" three times for "door actuators" as we were told this is what was causing security system to shut down vehicle. This did not solve the problem. GMC national service center was not helpful. They did not return calls or set-up special service appointment at local dealer as they promised. There are several incident dates of when we could not start our vehicle. Will use July 29th as one date, unable to start vehicle while on summer vacation in lake tahoe area. If this happens during real emergency it would be unfortunate.
While traveling at approximately 10 mph in traffic power assisted steering pump failed, forcing the consumer to pull off to side of road. Consumer stated that braking system also ran through this steering pump, and should be under separate systems. Dealership has examined vehicle, and was repairing this problem.
