One problem related to starter has been reported for the 1999 GMC Suburban. The most recently reported issues are listed below.
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.
