1999 GMC Suburban Electrical system Problems

“Gm passlock system faulty leaving me stranded far from home.thankfully, I was not in the road. My vehicle wouldn't start. This is a huge problem and many people have experienced it.”

“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. …”

“Repeated excessive wear on front brake pads and now on rear brake drums. We are very conservative drivers and typically get 80-100,000 miles on a set of brakes. This is our second set of front pads. We do tow heavy loads. The Suburban is equipped with a heavy duty towing package . It has already had the steering gear box replaced by the dealer. The front pads have been replaced once and the rear brakes have been adjusted, also the master cylinder has been replaced by the dealer. The brakes just do not seem of sufficient capacity to stop a vehicle of this mass towing load. …”

“Engine failed to start numerous times. Engine back fired and damaged starter. Found oem battery had leaked acid from positive terminal all over electrical wiring harness, rubber hoses, AC tubing, frame and dissolved protective hose wear shields. Dealer said he had seen this a lot and to call Gmc as the battery only had 36 month warranty. Battery warranty has nothing to do with leaking acid and extensive damage to wiring and hoses.”

“The right rear transmission seal broke twice and leaked fluid onto the rear brake. This resulted in loss of braking ability. The positive battery terminal leaked acid and caused the battery tray to rust”
