GMC 3500 Pickup Repair and Maintenance

A guide to problems, costs, maintenance and repair for your GMC 3500 Pickup

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.

The inside and outside door handles are prone to breaking.

The power door lock actuators may become slow to operate or stop working completely and require replacement.
