GMC Suburban 2500 ProblemsPower Door Lock Actuators May Fail
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The inside and outside door handles are prone to breaking.
Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.
